- Step 5: In a medium bowl, gently toss the raspberries with granulated sugar, cornstarch, lemon juice, and vanilla extract until well combined.
- Step 6: Press the remaining crumble mixture firmly into the bottom of the prepared baking pan to form an even layer.
- Step 7: Spoon the raspberry mixture over the crust, spreading it evenly.
- Step 8: Sprinkle the reserved crumble mixture over the raspberry filling.
- Step 9: Bake in the preheated oven for 30–35 minutes, or until the top is golden brown and the raspberry filling is bubbly.
- Step 10: Allow the bars to cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
- Step 11: Once cooled, slice into squares or bars. Serve and enjoy warm or at room temperature.
Tips & Variations
- For a nuttier texture, add 1/2 cup chopped walnuts or pecans to the crumble mixture.
- If fresh raspberries aren’t available, frozen ones work just as well; just thaw and drain excess juice before mixing.
- Try swapping raspberries for blueberries or blackberries for a different berry twist.
- Chill the baked bars in the refrigerator for firmer slices if preferred.
Storage
Store the raspberry crumble bars in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. To reheat, warm them gently in a microwave or oven to bring back their soft, crumbly texture.

FAQs
Can I use frozen raspberries for this recipe?
Yes, frozen raspberries can be used. Thaw them first and drain any excess liquid to prevent the bars from becoming too soggy.
How do I prevent the crumble topping from being too dry?
Make sure to use cold butter and mix it with dry ingredients until you get coarse crumbs. This ensures a tender, moist crumble. Avoid overbaking to keep the topping from drying out.
