Old-fashioned date squares feature a buttery oatmeal crumble and a chewy date filling. This recipe balances crumble and filling perfectly with a touch of cinnamon for a warm, comforting flavor. 
Date bars are a classic, simple treat that always attracts attention. Some call them date crumbles or matrimonial bars, but whatever the name, they belong on any dainty tray. The oat crumble is rich and buttery without drying out, while the date center is thick and chewy. A splash of orange juice in the filling adds natural sweetness and helps tenderize the dates for a smooth, jammy texture.
The Best Date Squares
Medjool dates are my top choice for flavor and texture, though any pitted dates will work. The date mixture should be cooked briefly to soften the fruit and break down the skins—this prevents hard bits in the finished bars. Prepare the date filling first and allow it to cool while making the base and topping.
The oatmeal crumble serves as both the base and the topping. Brown sugar and a hint of cinnamon intensify the flavor, while real butter delivers that classic, rich taste. Quick oats create a more uniform crumble, but old-fashioned rolled oats will also work if you prefer a heartier texture.
To assemble, set aside about 1 cup of the crumble for the topping and press the remaining mixture into a lined 8×8 inch pan for the base. Spread the cooled date filling over the base and crumble the reserved oat mixture on top. Bake until the top is golden and set, usually 50–60 minutes in an 8×8 pan. A 9×9 pan can be used instead; the bars will bake slightly faster (around 40–50 minutes) and be a bit thinner.
Allow the bars to cool completely—about 4 hours—before slicing. Cooling gives the filling time to set and yields clean slices. Use the parchment overhang to lift the bars from the pan and place them on a cutting board to slice easily.
Make-Ahead and Freezing
Date squares store well in an airtight container at room temperature for 3–4 days or in the fridge for up to a week. They also freeze nicely: cool completely, pack airtight, and thaw overnight in the refrigerator.
I love these bars for their tender, jammy date layer and crumbly oat topping—classic, comforting, and full of flavor. They’re perfect for potlucks, tea parties, holiday trays, or anytime you want a vintage dessert with modern appeal.
Date Squares
Equipment
- 8×8 inch pan
Ingredients
Date Filling
- 3 cups pitted Medjool dates (about 400 g)
- 3/4 cup water
- 1/4 cup orange juice
- 1 tablespoon brown sugar
Oatmeal Crumble (base and topping)
- 1 1/2 cups quick oats*
- 1 cup all-purpose flour
- 1/2 teaspoon cinnamon
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 3/4 cup unsalted butter, softened (not melted)
- 1 cup brown sugar
Instructions
- Preheat the oven to 350°F (180°C). Position a rack in the center and line an 8×8 inch (20×20 cm) pan with parchment, leaving an overhang.
- Date layer: Chop the dates into pieces. In a saucepan over low-medium heat, combine dates, water, orange juice and brown sugar. Stir gently as the mixture comes to a simmer and the dates begin to break down. When the dates are soft enough to mash with a fork, remove from heat and let cool.
- Oatmeal crumble: In a medium bowl, whisk together oats, flour, cinnamon, baking powder and salt. In a larger bowl, beat the brown sugar and softened butter until smooth and lump-free. Fold the dry ingredients into the butter until just combined; the mixture should be crumbly.
- Assemble & bake: Reserve about 1 cup of the crumble for the topping. Press the remaining crumble evenly into the bottom of the lined pan. Spread the cooled date filling over the base, then sprinkle the reserved crumble on top. Bake 50–60 minutes, until the top is golden brown.
- Remove from the oven and cool on a wire rack in the pan until completely cooled, about 4 hours. Use the parchment overhang to lift the slab onto a cutting board and slice with a sharp knife.
Notes
- A 9×9 inch pan is acceptable; bars will be thinner and bake for about 40–50 minutes. Bake times can vary with metal vs. glass or ceramic pans.
- Any dried, pitted dates can be used; Medjool offers a richer flavor and softer texture.
- Old-fashioned rolled oats work too; avoid instant or steel-cut oats.
- Store in an airtight container at room temperature for 3–4 days or refrigerated up to a week. Freeze cooled bars for up to 2 months and thaw in the fridge.
- Nutrition is an estimate based on cutting the pan into 16 bars.
