Grandma’s Authentic Matrimonial Cake: The Ultimate Canadian Date Square Recipe
Step into a world of nostalgic Canadian baking with our cherished Matrimonial Cake recipe. This dessert is more than just a treat; it’s a piece of culinary history, a comforting staple, and an old favorite that has graced countless tables across Canada. Known by a delightful array of names—date square, matrimonial bars, date slice, date crumble, date sandwich cake, and simply date bar—this particular recipe holds a special place in our hearts. It’s my Grandma’s secret, and I can confidently say it’s the absolute best date square I have ever had the pleasure of tasting! Its perfectly balanced sweetness and tender, crumbly texture set it apart, making it an irresistible delight.

This deceptively simple recipe enjoys immense popularity, especially during the festive Christmas season. However, its versatility ensures these delightful date bars are a fantastic choice any time of the year. You’ll often find them gracing tables at bustling Christmas markets, warm family reunions, lively bake sales, welcoming church gatherings, joyous bridal showers, and even solemn funerals, offering a moment of sweet comfort. Its rich, subtly sweet flavor pairs exquisitely with a warm cup of freshly brewed coffee or a soothing mug of tea, making it the perfect accompaniment for any occasion. In fact, this very recipe was the inspiration behind my equally popular Rhubarb Squares, showcasing its enduring appeal.
The Unique Charm of Matrimonial Cake
While this delightful date slice is widely known as Matrimonial Cake in many culinary circles, its name might be a bit misleading for those unfamiliar with Canadian traditions. Interestingly, especially in Western Canada, you’re far more likely to encounter it at a funeral gathering, providing solace and warmth, rather than at a wedding celebration. This charming paradox only adds to the unique character and beloved status of this iconic dessert.

If your love for delectable squares runs deep, you absolutely must explore some of my other celebrated recipes! Don’t miss out on the vibrant flavors of my Saskatoon Berry Squares, a true taste of the Canadian prairies.

Essential Ingredients for Matrimonial Cake
One of the many beauties of this date slice recipe lies in its simplicity. You’ll be pleased to find that you likely already have most, if not all, of these basic ingredients readily available in your pantry and fridge. We believe in using fresh, quality components to achieve the best flavor and texture for your homemade Matrimonial Cake.

- Quick Oats: For this recipe, quick oats are our preferred choice. They cook relatively faster than old-fashioned rolled oats and yield a softer, less chewy texture, which is ideal for the crumbly topping and base. It’s crucial, however, to steer clear of instant oats, as their finer consistency can result in a mushy texture in your squares.
- Unsalted Butter: We opt for unsalted butter to maintain precise control over the overall salt content in the recipe. This allows us to perfectly balance the flavors and avoid an overly salty outcome, ensuring the natural sweetness of the dates shines through.
- Dates, Pitted: Any variety of pitted dates you have on hand will work wonderfully for this recipe. While Medjool dates are often praised for their soft, caramel-like flavor, regular dates are perfectly acceptable. Since we’ll be simmering them in hot water, they will soften beautifully regardless of their initial texture, creating a rich and tender filling.
- Lemon Zest and Fresh Lemon Juice: This combination is a unique and essential element in my Grandma’s date square recipe. The bright, zesty notes of fresh lemon juice and finely grated lemon zest are not just for flavor; they play a critical role in balancing the inherent sweetness of the dates. This touch of citrus prevents the dessert from being overwhelmingly sweet, adding a delightful freshness that truly elevates the overall taste experience.

Versatile Variations & Smart Substitutions
One of the great things about this Matrimonial Cake recipe is its adaptability. Feel free to experiment with these variations and substitutions to suit your dietary needs or personal preferences, without compromising on flavor.
- Butter: If you only have salted butter available, you can certainly use it as a substitute for unsalted butter. Just remember to omit the additional salt from the recipe to prevent it from becoming too savory.
- Lactose-Free: To make this delicious dessert suitable for those with lactose intolerance, simply swap out regular butter for a high-quality lactose-free butter. The taste and texture will remain wonderfully consistent.
- Gluten-Free: Achieving a gluten-free version is straightforward. Replace the all-purpose flour with your favorite gluten-free flour blend. Ensure your oats are certified gluten-free as well to maintain a truly gluten-free treat.
- Dates: While regular pitted dates work perfectly, you can also use fresh dates or the softer, more luxurious Medjool dates. Don’t worry too much about their initial firmness; the cooking process with hot water will tenderize any variety, making them ideal for the creamy filling.
- Oats: If quick oats aren’t on hand, old-fashioned or rolled oats make an excellent substitute. To achieve a similar texture to quick oats, simply give the old-fashioned oats a few pulses in a food processor. This breaks them down slightly, ensuring they blend seamlessly into the crumb mixture.
Step-by-Step Guide: How to Make Matrimonial Cake
Crafting this classic Matrimonial Cake is a straightforward and rewarding process. Follow these simple steps to create a dessert that will impress your family and friends.
Preparation: Begin by preheating your oven to 350 degrees F (176 degrees C). Lightly spray a 9×13 inch baking pan with a non-stick cooking spray to ensure your squares don’t stick and are easy to remove.

In a small saucepan, combine your pitted dates, hot water, white granulated sugar, fresh lemon juice, lemon zest, and a pinch of salt. Cook this mixture over medium heat, stirring occasionally, until the dates become wonderfully soft and most of the water has been absorbed. This process typically takes about 5 to 10 minutes, transforming the dates into a rich, pulpy consistency.

Once the date mixture has achieved its desired soft texture, remove the saucepan from the heat. Stir in the vanilla extract, which adds a beautiful depth of flavor. Allow the filling to cool completely before proceeding to the next steps. Cooling is essential to prevent it from melting the butter in your crumb mixture later on.

In a large mixing bowl, combine the all-purpose flour, baking soda, brown sugar, and quick oats. Whisk these dry ingredients together thoroughly to ensure they are well combined and evenly distributed. This forms the basis for both your bottom crust and crumbly topping.

Add the cold, unsalted butter into the dry ingredients. Use a pastry cutter to cut the butter into the mixture until it resembles coarse crumbs. Alternatively, for a clever shortcut, refer to our “Top Tip” below about grating frozen butter. Continue mixing until the butter is evenly distributed and the mixture has a uniform, crumbly texture, perfect for both layers.

Take approximately half of the prepared crumb mixture and spread it evenly into the bottom of your greased baking tin. Use a spatula to gently but firmly pat it down, creating a compact and consistent base layer for your Matrimonial Cake. This forms a sturdy foundation for the delicious date filling.

Now, carefully spread the cooled date mixture over the pressed crumb base. For the best results and to prevent the crumb from mixing into your smooth date layer, here’s a helpful hint: dab spoonfuls of the date filling all over the crust first. Then, very gently spread it out with a butter knife or the back of a spoon, avoiding excessive pressure that could disrupt the bottom layer. Patience is key here to achieve a clean, distinct filling layer.

Gently sprinkle and pat the remaining half of the oat and flour crumble mixture evenly over the date layer. Use a spatula to lightly press it down, creating a beautiful, golden brown topping that will become wonderfully crisp during baking.

Place your assembled Matrimonial Cake into the preheated oven and bake for approximately 25 to 28 minutes, or until the oatmeal crumble topping turns a beautiful golden brown and the edges are slightly firm. Once baked, remove the pan from the oven and let it cool completely on a wire rack for at least 20 minutes before attempting to slice. Cooling thoroughly ensures clean cuts and prevents the squares from crumbling.
Expert Hint for Spreading the Filling: To ensure your date filling remains beautifully smooth and free of crumbs from the base, adopt this patient technique. First, drop small dollops of the cooled date mixture all over the bottom crust using a spatula or spoon. Then, with extreme care and a gentle hand, use a butter knife to spread these dollops together, working them across the crust. The key is to avoid dragging the knife across the dry crumb mixture underneath. This method requires a bit of patience, but the result will be a pristine, well-defined date layer.

Top Tip for a Perfect Crumbly Texture
For an exceptionally even crumbly texture in both your base and topping, and to make the process less messy, here’s a fantastic trick: instead of laboriously cutting cold butter into the flour and oat mixture with a pastry blender, try freezing your butter beforehand. Once frozen solid, simply grate the cold butter directly into your dry ingredients using a cheese grater. This method not only makes incorporating the butter significantly easier and faster but also ensures it is perfectly distributed throughout the mixture, leading to a consistently delicious and crumbly texture every time.

Serving Your Delicious Matrimonial Cake
This recipe for Matrimonial Cake yields approximately 18 generous slices, making it perfect for sharing with family and friends. However, you have complete flexibility to adjust the serving size to suit your needs. For larger gatherings or if you prefer smaller bites, simply cut the squares into more, smaller pieces. Conversely, if you desire fewer, more substantial portions, opt for larger cuts. You can also easily halve, double, or even triple the entire recipe by adjusting the serving number in the recipe card, and the ingredient quantities will automatically scale for your convenience.
For optimal flavor and texture, this date slice recipe is best served at room temperature or chilled. The slight chill enhances the firm structure of the squares and often deepens the flavors of the date filling and buttery oat crumble. For a charming presentation and easy handling, consider serving individual squares in extra-large paper muffin liners. This not only looks lovely but also makes them mess-free for guests.

Storage Tips for Freshness
To ensure your Matrimonial Cake remains as delicious as the day it was baked, proper storage is key. Follow these guidelines to keep your date squares fresh and enjoyable for longer.
Refrigerator: For short-term storage, place your date slices in an airtight container at room temperature for up to 2 days (48 hours). If you need them to last longer, transfer them to the fridge where they will stay fresh for up to a week in an airtight container. The cooler temperature helps maintain their texture and prevents the dates from drying out.
Freezer: Matrimonial Cake freezes beautifully, making it an excellent make-ahead dessert! To freeze, arrange the squares in a single layer in an airtight container, separating layers with parchment paper if stacking. They will keep well in the freezer for up to 3 months. For added convenience, you can even freeze individual squares directly in their paper cupcake liners, allowing for easy thawing and serving whenever a craving strikes.

Frequently Asked Questions About Matrimonial Cake
Why is it called Matrimonial Cake?
The name “Matrimonial Cake” is quite endearing, and much like Italian Wedding Soup, it refers more to a “wedding of flavors” than an actual marriage ceremony! While these delectable squares are often found at bridal showers, they don’t typically make an appearance at weddings themselves. The rich, sweet date filling marrying perfectly with the savory, crumbly oat crust creates a harmonious blend that inspired its unique name, symbolizing a perfect union of tastes.
Are Date Squares also known as Matrimonial Cakes native to Western Canada?
Yes, the names “Matrimonial Cake,” “Date Slice,” or “Date Square” are most commonly used in the Canadian Western Provinces. In contrast, in Eastern Canada, this dessert is more typically recognized as “Date Crumbles.” Growing up in Western Canada, specifically Winnipeg, we affectionately referred to slices, squares, or any small baked treats and goodies as “dainties.” This regional nomenclature highlights the rich culinary diversity within Canada.
What are date squares made of?
At its heart, a date square is a delightful two-part creation. It features a luscious, sweet, and often subtly spiced date filling, generously sandwiched between two layers of a rich, buttery, and satisfyingly crumbly oat mixture. This oat crumble serves as both the sturdy base and the irresistible crunchy topping, providing a perfect textural contrast to the soft date center.
What is the difference between quick oats and rolled oats, and why choose quick oats for this recipe?
The primary difference between rolled oats (also known as old-fashioned oats) and quick oats lies in their processing and cooking time. Rolled oats are larger, thicker flakes that are steamed for a shorter period, retaining more of their original shape and requiring a longer cooking time. Quick oats, on the other hand, are cut into smaller pieces and steamed for a longer duration, making them thinner, smaller, and much faster to cook. For our Matrimonial Cake, we prefer quick oats because their finer texture integrates more smoothly into the crumb mixture, creating a softer, more uniform base and topping that doesn’t feel overly chewy. This contributes to the overall melt-in-your-mouth experience of these squares.
Where do date squares (Matrimonial Cake) originate from?
The precise origins of the date slice, date square, or Matrimonial Cake are a subject of much delightful debate among culinary historians. Some attribute its heritage to Scottish baking traditions, given the prevalent use of oats and a simple, wholesome ingredient list. However, it is also a deeply traditional and widely loved dessert in Quebec, suggesting strong French culinary influences. Furthermore, it is a well-known and cherished treat in Newfoundland, indicating potential Irish connections. Regardless of its exact birthplace, this beloved dessert has clearly found a home and loyal following across diverse Canadian cultures, cementing its status as a true national classic.

Notes
Variations & Substitutions
- Butter – you can use salted butter instead of unsalted, but be sure to skip the salt in the recipe!
- Lactose-free – you can make this lactose-free by using a lactose-free butter.
- Gluten-free – use gluten-free flour.
- Dates – you can use regular pitted dates, fresh dates, or Medjool dates (they are softer). However, you are cooking them in hot water (which softens them) so regular dates are fine.
- Oats – You can use old fashioned/rolled as a substitute for quick oats. Just pulse the old-fashioned oats in the food processor a few times to break them down.
Top tip
Instead of using a pastry blender, I freeze my butter and grate it into the flour and oat topping/base. It’s less messy and helps to distribute the butter evenly into the mixture.
