Hey there, and welcome back, friends.
You are in for a sweet treat!
Don’t you just love a good bar recipe? These bars check all the boxes! A jammy filling, crumbly buttery topping, and easy to make.
I think of these bars as a classic recipe that you should have in your recipe box. They’re very versatile. You can use any fruit in the filling. Blueberries, mixed berries, and strawberries all make great substitutes.
These bars will always be a hit at any gathering. They’re easy for you to whip up last minute and everyone always gobbles them up. I always get compliments when I serve these bars.
I love the simplicity of this recipe. You can use fresh or frozen raspberries; which is perfect because sometimes all you have is frozen fruit on hand.
The bar crust and crumble topping is made with flour, rolled oats, and almond flour. Almond flour can be replaced with all-purpose flour if needed. The crust and crumble topping will still be soft, buttery, and crumbly.
Ingredients
- all-purpose flour
- almond flour
- rolled oats
- brown sugar
- salt
- ground cinnamon
- unsalted butter
- frozen raspberries
- granulated sugar
- a lemon
- vanilla extract
How to Make Raspberry Crumble Bars
Preheat the oven and lightly grease a square baking pan with some of the melted butter then line it with parchment paper leaving an overhang. To keep the parchment paper secure while baking, you can use a binder clip on each side of the pan.
Mix the flours, oats, brown sugar, salt, and cinnamon in a large bowl.
Add the melted butter and stir thoroughly until the mixture is moist and crumbly.
Press a third of the crumble mixture into your lined baking sheet in an even layer to form the crust. Reserve the remainder and set it aside.
Bake the crust in the preheated oven for 15 minutes until it is just beginning to turn golden around the edges.
While the crust is baking, add the thawed raspberries to a bowl along with the rest of the filling ingredients. Mix well.
In order to allow enough time for the raspberries to thaw, place the bag on the counter at room temperature about an hour before you’d like to bake the bars. Or, you can place it in the refrigerator to thaw overnight.
Spoon the raspberry filling over the baked crust in an even layer. It’s okay if the crust layer is still hot.
Sprinkle the remaining crumble mixture evenly over the top of the raspberry filling.
Bake the bars until golden brown and the raspberry juices are bubbling and have thickened.
Cool the bars for at least 1 hour.
Use a butter knife or palette knife to gently loosen the edges then remove the bars from the pan using the parchment paper. Cut the bars into 16 equal squares before serving.
The cooling process is vital to the final texture of the bars, so don’t skip it! The raspberry layer will thicken as the bars cool. To hasten the cooling process, place the pan in the refrigerator.
How to Store
Leftover raspberry crumble bars can be stored in an airtight container in the refrigerator for up to 5 days. You can also freeze them for up to 3 months. Unthaw the bars on a plate at room temperature.

- 2 ½ tablespoons all-purpose flour
