These healthy Blackberry Oat Crumb Bars are one of my favorite healthy desserts! They are so delicious, especially in the summer when fresh blackberries are in season. The best part is that these crumb bars are made with healthy ingredients yet taste like an indulgent dessert!
Blackberry Crumble Bars are so easy to make. The base doubles as the crumb topping and is made entirely in a food processor. The blackberries are also pureed in the food processor. The longest and most difficult part of this Blackberry Oat Crumb Bars recipe is letting them cool in the refrigerator for a few hours so that they cut without making a mess.
HOW TO MAKE HEALTHY BLACKBERRY OAT CRUMB BARS
These Blackberry Crumble Bars are SO easy to make. I’ll walk you through the whole process step-by-step to ensure your bars come out perfect!
- COMBINE THE DRY INGREDIENTS: Combine the rolled oats, almond flour, cinnamon, and salt in the bowl of a food processor. Pulse 3-4 times until the oats are slightly ground.
- COMBINE THE WET INGREDIENTS: Next, combine the wet ingredients by melting the coconut oil in a small pot over medium-low heat or in a microwave. Once the oil is melted, stir in the honey, and cashew butter until smooth.
- ADD THE WET INGREDIENTS: Add the wet ingredients to the food processor and process until everything is well combined.
- PRESS MIXTURE INTO A BAKING PAN: Remove 1 cup of the mixture and set aside for later (this will be the crumb topping). Using a spatula or your hands, press the remaining of the mixture into the bottom of an 8×8″ baking pan that has been lined with parchment paper. Use a fork to pierce holes in the crust to prevent it from puffing up during baking.
- BAKE THE CRUST: Bake the crust in a preheated oven for 10 minutes.
- MAKE BLACKBERRY PUREE: In the same food processor (there is no need to clean it), add the blackberries and tapioca starch. Pulse 3-4 times to break up the blackberries. If you want a smooth filling, pulse until the blackberries are completely pureed.
- POUR BLACKBERRY PUREE AND TOPPING: Pour the blackberry puree on top of the baked crust and use a small offset spatula to spread it out evenly. Use the crumb mixture that you set aside earlier and sprinkle it over the blackberry puree.
- BAKE BLACKBERRY OAT CRUMB BARS: Return the pan to the oven and bake for 25-30 minutes, until the crumb topping is golden brown. Once baked, remove the pan from the oven and place on a cooling rack to cool completely. Place the Blackberry Oat Crumb Bars in the refrigerator for at least 4 hours to set completely.
- CUT CRUMBLE BARS AND SERVE: Remove the Blackberry Crumble Bars from the refrigerator. Cut into squares and enjoy!
BLACKBERRY OAT CRUMB BARS: INGREDIENTS & SUBSTITUTIONS
Let’s chat about the ingredients and a few possible substitutions in this Blackberry Crumble Bar recipe!
- Rolled Oats. Quick-cooking oats can also be used here. Just be careful not to turn them into flour in the food processor!
- Almond Flour. I use superfine almond flour made from blanched almonds. Natural almond flour that is ground from whole almonds also works.
- Coconut Oil. Grass-fed butter can be substituted for coconut oil.
- Honey. I have made this recipe with a few different natural sweeteners, but honey is my favorite! For a vegan version use maple syrup.
- Cashew Butter. Any nut or seed butter works well in this recipe. My favorite is cashew or almond butter.
- Blackberries. You can use fresh or frozen blackberries. If you are using frozen blackberries, make sure to thaw them before pureeing. If you don’t have blackberries on hand, any other berry or fruit can be used!
