Preparing Raspberry Crumble Bars
Making raspberry crumble bars is a delightful experience that combines the sweet-tart flavor of raspberries with a buttery, crumbly topping. Follow these steps to achieve a delicious treat everyone will love!
Step 1: Prepare the Raspberries for Filling
The first step in creating your raspberry crumble bars is to prepare the raspberries. Begin by preheating your oven to 350°F. For this recipe, you’ll need two 12-ounce bags of frozen raspberries. Place them in a large colander and run warm water over them for about a minute. This helps to thaw them while removing excess ice. Let them drain for about an hour until they’re soft and thoroughly drained. Remember to mix the raspberries with ½ cup of granulated sugar, 2 tablespoons of flour, 1 tablespoon of cornstarch, and the juice of one lemon. This mixture will give your bars the perfect balance of sweetness and tartness!
Step 2: Make the Crumble Mixture
While the raspberries are draining, it’s time to work on the crumble. In a large mixing bowl, combine 3 cups of rolled oats, 3 cups of flour, 2 cups of brown sugar (loosely packed), 1 teaspoon of baking powder, 1½ cups of melted butter (I prefer salted for added flavor), and ½ teaspoon of salt. Stir the mixture until it resembles coarse crumbs. This crumble layer is what makes your bars so decadent!
Step 3: Press the Bottom Layer into the Pan
Next, grab a 9×13 inch baking pan and line it with parchment paper for easy removal later. Press two-thirds of this crumble mixture into the bottom of the pan firmly, creating a solid base. Once you've got it nicely packed down, bake it for 10 minutes. This step helps create a sturdy foundation for your raspberry filling.
Step 4: Layer the Raspberries on Top
After the base has baked, it’s time for the star of the show: the raspberries! Remove the pan from the oven and pour your prepped raspberry mixture evenly over the baked layer. Spread it out gently to cover the entire area with those juicy, vibrant berries. This layer will caramelize beautifully and offer that scrumptious fruit flavor.
Step 5: Add the Remaining Crumble and Bake
Finally, sprinkle the remaining crumble mixture over the raspberry layer. This will create a lovely, crunchy topping. Pop the pan back into the oven and bake for an additional 25-30 minutes, or until the top is golden brown. The aroma will be irresistible, and you might find it hard to wait for them to cool! After baking, allow the bars to set up by chilling in the refrigerator for a few hours. Trust me, the wait is worth it!
With these simple steps, you're on your way to enjoying stunningly delicious raspberry crumble bars that are sure to impress friends and family alike. Enjoy!

Variations on Raspberry Crumble Bars
Exploring Different Fruit Fillings

Each fruit offers a unique flavor profile that can elevate your bars to new heights. For more inspiration, check out this list of summer fruits that work beautifully in desserts.
Experimenting with Nut and Spice Additions
Adding nuts or spices is an easy way to customize your raspberry crumble bars. Throw in some chopped almonds or walnuts for extra crunch and richness. If you’re feeling adventurous, spices like cinnamon or nutmeg can enhance the comfort of these bars, blending harmoniously with the fruity filling. How about a hint of ginger for a warming kick? Experimenting not only personalizes the recipe but also gives you a chance to create something truly extraordinary that reflects your taste.
Cooking Tips and Notes for Raspberry Crumble Bars
Importance of Properly Thawing Raspberries
Thawing your frozen raspberries properly is crucial for delicious raspberry crumble bars. Placing them in a colander and running warm water over them helps release excess moisture.

Best Practices for Achieving a Perfect Crumble Texture
To create that irresistible crumble texture, use old-fashioned rolled oats instead of quick oats.

Remember, pressing two-thirds into the pan provides a solid base for your raspberry filling. After baking, the crumble should be golden brown and fragrant, giving you that comforting homemade dessert satisfaction!
