2 tablespoons butter, melted, plus more for greasing
1 teaspoon vanilla extract
1 1/2cups blueberries, fresh or frozen
Crumble Topping (optional):
2 tablespoons butter
2 tablespoons rolled oats
1 tablespoon brown sugar
1 tablespoon almonds, chopped or sliced
Instructions
Preheat the oven to 350° F and grease a 9×9′ baking pan.
In a large bowl, combine the dry ingredients; rolled oats, brown sugar, almonds, cinnamon, baking powder and salt, and stir to combine.
In a medium bowl, combine the wet ingredients; milk, eggs, melted butter and vanilla extract, and whisk to combine.
Add the wet ingredients to the dry ingredients and mix until well incorporated. Add blueberries and gently fold into the oatmeal mixture.
Transfer the mixture to the greased baking pan, gently spreading it evenly into the pan with a spatula.
Optional: In a small bowl, combine the crumble topping ingredients and mix together with your hands until well incorporated, then gently scatter the topping over the top of the pan.
Transfer baking pan to the oven to bake for 30-35 minutes until bars are cooked and the top is golden brown.
Once cooked, removed from the oven, allow to cool slightly (5-10 minutes), and then slice into 9 even squares.
The bars can be served immediately, stored in an airtight container in the fridge for 5 days or in the freezer for 3 months.
