Ingredient Overview
The raspberry crumble tart bars are crafted from a handful of pantry staples and fresh berries. Lets break down the key components:
- Almonds: Toasted and roughly chopped, these add depth and a subtle, nutty crunch to the crust and crumble. For nut allergies, substitute with toasted coconut flakes.
- All-purpose flour: The backbone of the crust and crumb topping.
- Kosher salt: Essential for balancing sweetness and amplifying flavor.
- Cold, unsalted butter: Provides richness and ensures the crust is tender and crumbly.
- Granulated sugar: Delicately sweetens the filling and bonds the crumb.
- Fresh raspberries: The true stars, bringing tangy juiciness and color.
- Optional: Powdered sugar for finishing.
Equipment Youll Need
- Large mixing bowls
- Parchment paper
- Pastry blender or your fingertips
- Rolling pin (optional but helpful)
- Square (8×8-inch), round, or quarter-sheet (9×13-inch) baking pan
- Serrated knife for cutting bars or wedges
Step-by-Step: How to Make Raspberry Crumble Tart Bars
1. Prepare the Ingredients
- Toast almonds if using, then roughly chop.
- Wash and dry raspberries. Remove any leaves or stems.
- Cut cold unsalted butter into cubes for easy blending.
2. Make the Crust and Crumble
By hand: Place flour and kosher salt in a large bowl and stir. Add cold butter cubes and toss to coat. With your fingertips or a pastry blender, work the butter into the flour until the mixture looks like small peas. Stir in sugar, then add chopped almonds; combine until the mixture forms clumps but is not fully cohesive.
Add cold water one tablespoon at a time, tossing until the dough begins to hold together. It should stay crumbly but clump easily when pinched between your fingers. If it feels dry, add additional water sparingly.
3. Form the Crust
Lay out parchment paper in the baking pan for easy removal after baking. On a floured surface, roll the dough into a square or circle large enough to fit your pan—about 10×10 inches for an 8-inch square or 13-inch circle for a tart pan. Press the dough into the bottom and 1-inch up the sides. If there’s extra dough, fold it over to reinforce edges. Patch up any holes as needed.
4. Add the Raspberry Filling
Spread the fresh raspberries in an even layer over the prepared crust. If the berries are especially tart, you may toss them with a touch of granulated sugar first, but typically raspberries’ natural sweetness and tartness shine here. There’s no need for jam, cornstarch, or excess sweeteners.
5. Top with Crumble
Evenly sprinkle the reserved crumb mixture over the berries. It may look like a thick layer, but it will bake down and create the signature crunchy, golden topping that defines the tart bars.
6. Bake
- Bake in a preheated oven at 375°F (190°C) for 40 to 50 minutes.
- If the topping browns too quickly, tent loosely with foil during the last 10-15 minutes.
- Bars are done when the top is deeply golden and berry juices bubble up through the crumbs.
7. Cool and Serve
- Let bars cool for at least 20 minutes in the pan on a wire rack.
- Use the parchment sling to lift them out and cool completely before slicing.
- Optional: Dust with powdered sugar before serving.
- Slice into bars or wedges with a serrated knife.
Storage
Store at room temperature or refrigerate, lightly wrapped, for up to 5 days. The bars can also be frozen for up to a month in an airtight container.
