Step‑by‑Step Instructions for Raspberry Crumble Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). Line an 8-inch square baking pan with parchment paper, letting the edges overhang slightly, which will make removal easier later. This ensures your Raspberry Crumble Bars will bake evenly and have a perfect texture.
Step 2: Mix the Cookie Base
In a large bowl, combine gluten-free all-purpose flour, cane sugar, and salt, mixing well to incorporate the dry ingredients. Add dairy-free butter to the mixture, using your hands or a pastry cutter to blend until a soft dough forms. This will create a beautiful buttery base for your bars.
Step 3: Set Aside Dough
Reserve 1/3 cup of the dough for the crumble topping—set it aside in a small bowl. Now, press the remaining dough firmly and evenly into the bottom of the prepared baking pan. Ensure the dough covers the bottom completely for a uniform layer once baked.
Step 4: Bake the Base
Place the pan in the preheated oven and bake the cookie base for 14-16 minutes, or until the edges are lightly golden brown. Keep a watchful eye on it; this step creates a sturdy foundation for your Raspberry Crumble Bars filled with delicious raspberry goodness.
Step 5: Prepare the Filling
While the base is baking, take a bowl and mix together the raspberry preserves, fresh raspberries, and fresh lemon juice until well combined. This vibrant filling not only brightens the taste but also adds a lovely texture to your filling, preparing it for when it meets the warm crust.
Step 6: Make the Crumble Topping
In another bowl, combine the reserved dough with brown sugar, rolled oats, and chopped pecans or nuts of your choice. Use your fingers to mix until the mixture becomes crumbly. This topping is essential for that delightful crunch on your Raspberry Crumble Bars that everyone will love.
Step 7: Assemble the Bars
Once the base is done baking, remove it from the oven and immediately pour the prepared raspberry filling over the warm cookie base. Then, evenly sprinkle the crumble topping over the filling without pressing it down, creating a lovely contrast that will bake beautifully together.
Step 8: Final Bake
Return the pan to the oven and bake for an additional 22-25 minutes, until the filling is bubbling and the crumble topping has turned a lovely golden brown. Ensure the kitchen is filled with mouthwatering aromas as your Raspberry Crumble Bars reach their perfect doneness.
Step 9: Cool and Serve
Once baked, allow the Raspberry Crumble Bars to cool completely in the pan. This is crucial; cooling fully will ensure they hold their shape when cut. After they have cooled, lift them out using the parchment paper edges and cut into squares for serving.

Make Ahead Options

Absolutely! Using fresh, ripe raspberries ensures the best flavor and texture in your filling. Look for berries that are plump, firm, and free from dark spots or mold.

Yes! To freeze your Raspberry Crumble Bars, let them cool completely, then place them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe container or bag, where they can last up to 3 months. When you’re ready to enjoy, simply thaw them in the fridge overnight or at room temperature.
What if my crumble topping is too dry?
If your crumble topping feels too dry and crumbly, you can add a tablespoon of dairy-free butter or a splash of water to help bind the mixture. Make sure not to overmix; you want that delightful crumbly texture for the topping!
Are there any dietary considerations with these bars?
These Raspberry Crumble Bars are naturally gluten-free, vegan, and can be made nut-free by substituting pecans with extra oats. However, if you or your guests have allergies, always check the ingredients of your flour and preserves to ensure they are safe for everyone.
