These healthy berry oat crumble bars burst with flavour! They are made with an easy vegan oat crust and crumble and are loaded with fresh mixed berries! They make a wonderful breakfast, snack or dessert.
The days have gotten warmer and berry season is right around the corner, so I felt an urge to bake with berries! My strawberry and raspberry crumble bar recipe is the most popular on the blog, which led me to make a new mixed berry version.
These healthy berry oat crumble bars are naturally sweetened, dairy free, gluten free and vegan, but trust me – you would never know! They make a fresh and nourishing dessert, snack, or breakfast. They basically consist of a delicious oat crust, a layer of strawberries, raspberries and blueberries in the middle and more oat crumble on top. So good!
WHAT INGREDIENTS WILL YOU NEED FOR THESE HEALTHY BERRY OAT CRUMBLE BARS?
Let’s take a closer look at the key ingredients you will need for this recipe:
The oat crust and crumble
- Oats: I’d recommend using rolled (also called large flake) oats for this recipe for the best texture. I love including oats in healthier treats for their health benefits. They are a healthy source of carbs, and are rich in fiber and antioxidants.
- Almond flour: I like baking with almond flour mostly for its taste. It also helps keep baked goods moist and tender, which is what I wanted for this crust and crumble mixture.
- Maple syrup: the crumble mixture is naturally sweetened with maple syrup.
- Coconut oil: coconut oil is my favourite substitute for butter. I prefer it over olive oil, which can often have a stronger taste in baked goods.
- Other ingredients: vanilla extract, baking powder and salt.
The fruit filling
- Fresh berries: I used a combination of strawberries, raspberries and blueberries for this recipe.
- Lemon juice: lemon juice is acidic, which helps balance the sweetness of the fruit, and it also adds a note of freshness.
- Cornstarch: adding a bit of cornstarch to the fruit helps thickening the juices.
- Maple syrup: I included 2 tbsp of maple syrup for sweetness but I would adapt the quantities depending on how sweet your fruit are. If they are a bit more tart, add an extra tablespoon of maple syrup; and if they are really sweet, only add one tablespoon.
HOW TO MAKE THESE BERRY OAT CRUMBLE BARS?
These crumble bars are really easy to make! I’ve included pictures below with a step by step of how the layering is done.
First, you’ll want to make the oat crumble mixture, which will be used for both the crust layer and crumble layer. Mix your oats, almond flour, baking powder and salt in one bowl. In a separate bowl, whisk your melted coconut oil, maple syrup and vanilla extract. Add the wet ingredients to the dry ingredients and mix. Once all the ingredients are combined, you will pack 2/3 of the crumble in an 8×8 pan lined with parchment paper, and bake at 350F for 10 minutes. This will ensure that your bottom layer is “strong” and doesn’t get mixed with the berry layer.
While the crust is baking, mix in a bowl your strawberries, raspberries, blueberries, lemon juice, maple syrup and cornstarch. I personally like to mash the berries a little with my spatula to have a mix of fruit purée and some chunks.
Layer your berry mixture on top of the baked crust. Crumble the last third of the dough on top and bake for another 25 to 30 minutes. Let the bars cool a bit at room temperature and then chill them for about 2 hours in the fridge. This step is really important to have nice solid bars. Once completely cooled, remove the bars from the pan with the help of the parchment paper and cut them into 9 squares.
HOW TO STORE THESE CRUMBLE BARS?
Once cut, store the bars in an airtight container in the fridge for up to 5 days (that’s if they last that long). The bars might become a little more tender and soft after the first day, but they will still be as delicious!
