I’ve been leaning hard into nostalgic bakes lately; and these coffee date squares are my latest crush. An oat-flecked bar cookie with a layer of sweet date filling, date squares make a perfect sweet bite alongside your warm beverage of choice.
Date squares are popular coffeehouse fare here in Canada. Apparently in some parts of the country they’re known as “matrimonial cake” — possibly because the varying flavors and textures mirror the complexities of marriage (I know…it’s a stretch), or maybe because they were frequently served at weddings.
Name speculations aside, these old-fashioned treats are simple to make and enjoy. I’ve added coffee to help balance the sweetness of the dates, but these bars just call for personalization. Try simmering the dates in a mixture of water and orange or lemon juice (add some orange zest to the crumble if you want to play up the citrus notes!), or swap in your favorite medley of warming spices.
A few notes:
- I use a food processor to make the crumble mixture for speed’s sake, but if you can also rub the butter in by hand. In general, I prefer using cold butter (vs. softened or melted) for crumb bars and streusels as I find the crumbs hold their shape well and have my ideal firm-but-tender texture after baking.
- If you don’t want to use nuts, you can swap in an additional 45 g (1/2 c) oats instead (add them at the end with the rest of the oats).
- You can use plain all-purpose flour for the crumble, but I think whole grain flour adds extra character and flavor to these bars! I’m a big fan of Flourist sifted Red Fife in baked goods, but you could try white whole-wheat, a mix of all-purpose and whole grain, or all whole grain for a heartier texture.
Coffee date squares
Makes one 8×8 pan
For the coffee date filling:
- 300g (1 3/4 c) dried Medjool dates, pitted and chopped
- 200g (3/4 c plus 2 Tbsp) freshly brewed coffee
- 1/2 tsp baking soda
For the crust and crumb:
- 188g (1 1/2 c) flour (I used Flourist sifted Red Fife)
- 45g (1/3 c) toasted walnuts or hazelnuts
- 1 tsp Diamond Crystal kosher salt
- 100g (1/2 c) light brown sugar
- 1/4 tsp baking soda
- 1 tsp finely ground coffee
- 1 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/4 tsp ground cardamom
- 200g (14 Tbsp) unsalted butter, cubed and cold
- 90g (1 c) rolled oats (preferably regular, not quick)
- Preheat the oven to 350F with a rack in the middle. Line an 8×8 square pan with two criss-crossed pieces of parchment paper, leaving a few inches of overhang on all edges. (This makes it easy to remove the squares from the pan later.)
- Make the coffee date filling: In a medium saucepan, combine the chopped dates and coffee. Cook over medium heat, stirring and mashing the dates frequently, until the dates have broken down and the mixture is thick and relatively smooth, about 10 minutes. Add the baking soda and stir to combine thoroughly. Scrape filling into a bowl and let cool while you continue with the recipe.
- Make the crust and crumb: In the bowl of a food processor, add the flour, nuts, salt, sugar, baking soda, ground coffee, and spices. Pulse several times until well combined. Scatter the cold butter over the top and pulse until the mixture starts to form small clumps. Add the oats and pulse just a few times to incorporate — you don’t want the oats to completely break down as they add a nice texture.
- Assemble and bake the squares: Transfer approximately 2/3 (400g) of the crumb mixture to the prepared pan. Use a small glass or measuring cup to press the crumbs firmly and evenly across the bottom. Bake for 10 minutes, or until just set.
- Use a small offset spatula to spread the date filling evenly over the par-baked base (no need to let the base cool) and sprinkle the remaining crumbs evenly over the top. Bake until the top is golden brown, about 22-30 minutes. Let cool completely before slicing — I find chilling the bars in the fridge for a couple hours makes slicing a breeze. Refrigerate leftovers in an airtight container for up to 5 days or freeze for longer storage.
