Instructions

Preheat and Prep – Preheat your oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving an overhang for easy removal.
Mix Dry Ingredients – In a large bowl, combine rolled oats, whole wheat flour, brown sugar, baking powder, cinnamon, and salt. Stir until thoroughly mixed.
Combine Wet Ingredients – In a separate bowl, whisk together the melted butter, egg, and vanilla extract until smooth.
Prepare Blueberry Filling – In another bowl, toss blueberries with maple syrup (or honey), cornstarch, and lemon juice. Stir until the berries are evenly coated.
Assemble Bars – Pour wet ingredients into the dry ingredients. Mix until a crumbly dough forms. Reserve 3/4 cup of the mixture for topping. Press the remaining dough firmly into the prepared pan to form an even base.
Add Blueberry Layer – Spread the blueberry filling evenly over the crust.
Topping and Bake – Scatter the reserved oat mixture evenly over the blueberries. Bake in the preheated oven for 35–40 minutes, or until the topping is golden brown and the blueberry layer is bubbling.
Cool and Serve – Let the bars cool completely in the pan, then lift them out using the parchment paper. Slice into bars and enjoy!

Notes

If using frozen blueberries, do not thaw before mixing to avoid excess moisture.
Bars can be stored in an airtight container at room temperature for up to 2 days, or refrigerated for up to 1 week.
For a vegan version, use coconut oil instead of butter and a flaxseed egg instead of a regular egg.
Substitute honey with maple syrup if you prefer a different sweetener.
