Raspberry Crumble Bars Ingredients

For the Cookie Base

• Salt – Enhances flavor and balances sweetness. No alternative needed.
• Dairy-Free Butter or Regular Butter – Contributes to the richness and texture of the crust. Substitution Note: For a more robust buttery flavor, use 9 tablespoons; coconut oil can serve as a dairy-free alternative.
For the Crumble Topping
• Packaged Brown Sugar – Adds moisture and a deeper flavor to the crumble. No alternative needed.
• Pecans, finely chopped – Offers crunch and flavor in the crumble topping. Substitution Note: Substitute with additional oats for a nut-free version.
• Gluten-Free Old-Fashioned Rolled Oats – Contributes texture to the crumble. Substitution Note: Can be omitted if oat-free is necessary; extra pecans can fill in.
For the Raspberry Filling
• Raspberry Preserves – Sweetens and flavors the filling. Note: Ensure it’s gluten-free.
• Fresh Raspberries – Provides fresh flavor and a jammy texture to the filling. Fresh or frozen can be used, but thaw and pat dry to avoid excess moisture.

Step‑by‑Step Instructions for Raspberry Crumble Bars

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 375°F (190°C). While it heats up, line an 8-inch square baking pan with parchment paper, allowing some overhang on the sides for easy removal later. This simple step ensures your Raspberry Crumble Bars will come out intact and beautifully presented.

Step 2: Make the Cookie Base
In a mixing bowl, combine gluten-free all-purpose flour, cane sugar, and salt, blending them well. Gradually incorporate softened dairy-free butter into the dry ingredients, using your hands or a spatula to mix until a dough forms, pulling away from the bowl sides. This dough creates a buttery, rich foundation for your bars.

Step 3: Reserve Dough and Press
Set aside 1/3 cup of the cookie dough for the crumble topping. Press the remaining dough firmly into the bottom of the prepared baking pan, ensuring an even layer about 1/4 inch thick. This forms the sturdy base of your Raspberry Crumble Bars that will hold up beautifully under the fruity filling.

Step 4: Bake the Crust
Place the pan in the preheated oven and bake for 14-16 minutes or until the edges begin to turn a lovely golden brown. Keep an eye on the crust to prevent over-baking. Once done, remove it from the oven and set it aside to cool slightly while you prepare the filling.

Step 5: Prepare the Raspberry Filling
In a medium bowl, mash together the raspberry preserves, fresh raspberries, and fresh lemon juice using a fork or potato masher. Mix until well combined but still lumpy, allowing some texture to shine through. This vibrant mixture will provide a sweet and tangy contrast to the cookie base of your Raspberry Crumble Bars.

Step 6: Make the Crumble Topping
Return to the reserved cookie dough and combine it with packed brown sugar, finely chopped pecans, and gluten-free rolled oats. Mix gently until it resembles a crumbly texture, perfect for sprinkling. This topping adds a delightful crunch to your bars, enhancing both flavor and texture.

Step 7: Assemble the Bars
Once the crust has cooled slightly, spread the raspberry filling evenly over the baked base with a spatula. Evenly sprinkle the crumble topping on top of the filling, ensuring new bites reveal layers of tasty goodness in your finished Raspberry Crumble Bars. This step layers the flavor beautifully.

Step 8: Bake the Bars
Return the assembled pan to the oven and bake for an additional 22-25 minutes, or until the filling is bubbling and the crumble topping is golden brown. The tantalizing aroma will fill your kitchen as these bars become an irresistible treat, promising a delightful balance of textures.

Step 9: Cool and Serve
Allow the Raspberry Crumble Bars to cool completely in the pan on a wire rack, which will help the flavors meld beautifully. Once cooled, lift out the bars by the parchment paper overhang and cut them into squares for serving. Enjoy the fruits of your labor in every delicious bite!

Raspberry Crumble Bars Recipe FAQs

How do I select ripe raspberries for this recipe?
Absolutely! When choosing fresh raspberries, look for berries that are plump, firm, and vibrant in color. Avoid any with dark spots or mold, as these can affect the flavor and texture of your Raspberry Crumble Bars. If raspberries aren’t available, feel free to use frozen ones; just make sure to thaw and pat them dry to remove excess moisture beforehand.

What is the best way to store leftover Raspberry Crumble Bars?
Store your bars in an airtight container in the refrigerator for up to 5 days. Ensure they have completely cooled before placing them in the container to keep them fresh. You can also place parchment paper between layers to prevent sticking!

Can I freeze Raspberry Crumble Bars? How?
Yes, you can definitely freeze them! Wrap each bar individually in plastic wrap and then place them in a freezer-safe bag. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw them in the refrigerator overnight or at room temperature for about 2 hours. If you prefer them warm, pop them in the microwave for 10-15 seconds after thawing.

What if the topping is too crumbly or doesn’t stick?
Very! If your crumble topping isn’t sticking together, ensure that you mixed the ingredients sufficiently so the butter is evenly distributed. If it still seems too dry, try adding a touch more melted butter—about 1 tablespoon at a time—until the desired crumbly consistency is achieved. This adjustment will help it adhere beautifully over the raspberry filling!

Are there any dietary considerations with these Raspberry Crumble Bars?
These bars are naturally gluten-free, vegan, dairy-free, and egg-free, making them a fantastic treat for a variety of dietary needs. However, if you’re serving them to someone with nut allergies, just substitute the pecans with additional gluten-free oats or seeds for a satisfying crunch without the nuts. Enjoy peace of mind while sharing these delightful treats!

Can I use different fruits in this recipe?
The more the merrier! While raspberries provide a delightful tartness, feel free to swap them out for other fruit preserves like blueberry, strawberry, or even apricot. Each variation brings its own unique flavor that enhances the crumble bars wonderfully, so have fun experimenting!
