We love enjoying Raspberry Oatmeal Bars as a quick snack or dessert! The recipe is easy to make and super versatile. Plus, the contrast of the fruity raspberry preserves with the oat crumble is just so delicious. We are giving you many options for the flour, sweetener, and fruit filling, so you can customize these and make them your own. They can easily be adapted to be gluten-free and vegan, plus you can change the flavor with any fruit preserves you like best.

Why you should make this recipe

  • Hearty & delicious: The oat crumble crust and topping has the best texture and is perfectly sweetened. In addition, the raspberry filling is a good mix of tart and sweet.
  • Easy to make: Everything is stirred together in one bowl, and these raspberry bars can be popped in the oven in no time at all!
  • Versatile: They can be made with all-purpose, whole wheat, spelt, or gluten-free flour. You can also use a variety of sweeteners and fruit fillings.
  • Great for meal prep: We like to make a batch of these on the weekend to enjoy all week long for quick snacks and sweet treats! They store well and can even be stored in the freezer.

Ingredients needed

Raspberry crumble bars are made with simple, healthier baking ingredients, like coconut oil, your choice of flour, natural sweetener, and sugar-free preserves. Here’s everything you’ll need:

  • Flour: Use your choice of all-purpose flour, whole wheat flour, or spelt flour. You can even make these gluten free by using a gluten-free all-purpose flour.
  • Instant oats: For this particular oat bar recipe, instant oats will give you the best texture.
  • Coconut oil: Adds just enough moisture to the oat crumble.
  • Sweetener: To perfectly sweeten and moisten the oat layer, you can use honey, agave or maple syrup to make these vegan.
  • Flavorings: Both vanilla extract and cinnamon add warm subtly sweet flavor.
  • Sugar: To keep these naturally sweetened, use coconut sugar. However, brown sugar or cane sugar works too.
  • Baking powder: For proper baking.
  • Salt: To enhance the flavors.
  • Preserves: We used sugar-free raspberry preserves to make this recipe, but the bars would be delicious with other varieties of preserves too.

How to make this recipe

  1. Make the oat crumble: Preheat the oven to 350°F. In a large bowl, add all the ingredients except for the preserves you will be using for the filling. Using a spoon or spatula, toss everything together until they are combined.
  1. Press the crust into the pan: Next, spray an 8×8-inch baking pan with non-stick spray. Using a spatula, pour about ⅔ of the mixture onto the pan. Then using either your hands or the spatula, press the mixture into the bottom of your pan until it is even throughout.
  1. Add the filling: Using a spoon, spread the preserves all over the oat/flour mixture and avoid spreading it too close to the edges. This will prevent the preserves from burning and sticking to the pan.
  2. Top with crumble mixture: To add the remaining mixture, use your hands to spread them over the preserves in a crumble-like fashion. Gently press down the crumbles with your fingers so they lightly stick to the preserves.
  1. Bake: Place the pan in the oven and bake for 25-30 minutes or until they are lightly browned on the top.
  2. Cool & serve: Remove from the oven, place the pan onto a cooling rack, and allow it to cool completely. Cut the oat bars into 9 even square pieces and serve!

Expert tips

  • Cool before slicing: You will get the cleanest slice if you let the bars completely cool before slicing. If you are in a hurry to cut them, place the pan in the fridge to speed up the process.
  • Cutting the bars: Be sure to use a sharp knife to cut the bars. A sharp knife will help you make a nice, straight cut and get completely through the bottom layer of crust.
  • Meal prep: Meal prep these to enjoy throughout the week. We love them cold straight out of the fridge, but they also taste great at room temperature. If you want to enjoy them a bit warm, pop them in the microwave for about 20 seconds.
  • Double the filling: Like more Raspberry filling? Double it up if you like.

Frequently asked questions

Can I use a different filling?

Yes, some other delicious fillings are strawberry, blueberry, peach or apricot. The options are endless!

Can I use rolled oats?

Since we have not tried old-fashioned rolled oats in this recipe, we cannot recommend this substitution. It may work but it will change the texture of the bars.

Raspberry oat bars are a healthier snack or dessert. The recipe uses wholesome ingredients with plenty of fiber, antioxidants, vitamins, and minerals.
