How to Make Raspberry Crumble Bars Recipe
Simple to put together and quick to bake, Raspberry Oatmeal Bars will become one of your favorite EASY go-to dessert recipes!
PREHEAT AND PREP. First, preheat the oven to 350 degrees and line a 9 x 9-inch baking pan with parchment paper, leaving enough to overlap the sides.
MAKE THE CRUMBLE TOPPING. First, add the oats, flour, brown sugar, and cinnamon to a medium bowl and mix with a fork.
MIX IN BUTTER. Add the butter to the bowl and mix with the fork (or your fingers) until you have coarse crumbs. Then, set the bowl aside until you’re ready to add it to the top of the filling.
SWEETEN THE RASPBERRIES. Once the crust is finished baking, empty one package of raspberries into a bowl and sprinkle with sugar, mixing with a fork.
SPREAD ON WARM CRUST. Then, spread the sweetened raspberry mixture on top of the warm crust and top it with the other package of whole raspberries.
LAYER CRUMBLE ON TOP AND BAKE. Sprinkle the crumble mixture over the raspberries and return the pan to the oven. Continue baking for 30 to 35 minutes until the crumble is golden brown.
COOL, SLICE, ENJOY! Finally, cool the baked bars in the pan on a wire rack for 20 minutes, then use the sides of the parchment paper to remove them from the pan. NOTE: The bars will be easier to slice into squares if chilled for a few minutes in the fridge first – Enjoy!

Frequently Asked Questions
Yes! The Raspberry Oatmeal Crumble Bars can be left out at room temperature for about 2 hours. After that, it’s best to refrigerate them to help preserve the freshness of the raspberry filling. The berries spoil more quickly at room temperature.
Sure, you can use frozen raspberries, but fresh berries will give you the best results. If you do use frozen, thaw and drain them well to remove the excess moisture before adding them to the filling. This helps prevent the bars from becoming too soggy.
You can reduce the sugar by using less in both the crust and crumble mixture or substitute with a sugar alternative like stevia or erythritol. Keep in mind that this may slightly change the taste and texture, but the bars will still be delicious!
It’s best not to use quick oats or instant oats for the crumble topping. These oats are processed differently and tend to become too soft and mushy when baked.
