About The Recipe
I am always looking for a little something sweet to snack on. A sweet, easy, grab-and-go kinda snack. That’s why we’ve made these delicious raspberry crumble bars!
Raspberries are actually one of my favorite berries ever – so, when we baked homemade raspberry jam between two layers of a delicious and buttery crumble, it easily became my new favorite treat!
They are great for any season because you can use fresh raspberries when they’re available, or frozen when they’re not, to make your own jam. You can even use your favorite store-bought brand.
No matter which you choose to use, these little bars will always be SO good!

Ingredients
- All-Purpose Flour
- Old Fashioned Oats
- Brown Sugar
- Salted Butter
- Raspberry Jam

Instructions
Combine the flour, oats, and brown sugar in a food processor and pulse until it’s combined.


Add in all the butter and pulse until it starts to come together.


Transfer 2/3rds of the crumble mixture into a greased pan and gently press down. Bake at 350 for about fifteen minutes, or until it’s lightly browned.



Spoon the raspberry jam over the baked crumble base and spread evenly. Sprinkle the rest of the crumble mixture over the top of the jam layer. Place back in the oven and bake for 40 minutes.




Let cool, slice, and serve!

Do you think you could substitute Gluten Free Flour? I’m willing to try (with baking powder and a dash of salt).
Hi Val! You shouldn’t have any problem substituting Gluten Free Flour for the All Purpose. You do need to use a binder like xanthan gum. You will need about 1/4 teaspoon. However, if you are using a 1 to 1 or measure for measure Gluten Free Flour, you won’t need to add the binder because it is already mixed in. You don’t need the baking powder or salt. Let me know if you have any more questions.
Great recipe. Didn’t change a thing and it was delicious!
Hi Debbie! we’re so glad to hear you like this recipe just as much as we do!

Very tasty dessert, the only comment/recommendation I would give is to let people know if they double/triple the recipe they need to use a larger dish. Maybe for the 2x use a 9×13 baking dish and the 3x use a 13 x 11 baking dish. Some one new to baking would not think of that adjustment.
