Ingredients
Oat Crust & Topping
- 1 cup old-fashioned oats
- 3/4 cup all-purpose flour (or gluten-free flour blend)
- 1/3 cup light brown sugar
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 teaspoon cinnamon (optional)
- 6 tablespoons unsalted butter, melted (or coconut oil)
- 1 teaspoon vanilla extract
Blueberry Filling
- 1 cup blueberries (fresh or frozen)
- 1/4 cup granulated sugar
- 2 teaspoons cornstarch
Instructions
- Preheat & Prep Pan: Preheat your oven to 375°F (190°C). Line an 8-inch square baking pan with parchment paper, leaving enough overhang on the sides for easy removal of the bars once baked.
- Mix Dry Ingredients: In a large bowl, combine the oats, flour, brown sugar, baking soda, salt, and cinnamon (if using). Stir until evenly mixed.
- Add Wet Ingredients: Pour in the melted butter and vanilla extract. Stir until the mixture forms a crumbly texture. It should hold together when pressed between your fingers.
- Form the Base: Transfer half of the oat mixture into the prepared pan. Press it down firmly and evenly to create the base layer for the bars.
- Prepare Blueberry Filling: In a separate bowl, toss the blueberries with the granulated sugar and cornstarch until the berries are well coated and the mixture looks syrupy.
- Layer the Blueberries: Spread the blueberry filling evenly over the oat base in the pan.
- Add the Crumble Topping: Sprinkle the remaining oat mixture over the blueberries. Gently press down, just enough to hold things together but still leave a crumbly texture.
- Bake: Place the pan in the oven and bake for 35–40 minutes, or until the top is golden brown and the blueberry filling is bubbling.
- Cool & Slice: Allow the bars to cool completely in the pan on a wire rack. Once cooled, use the parchment paper overhang to lift them out and cut into squares.
Notes
- For extra texture, add a handful of chopped nuts to the oat mixture.
- Substitute coconut oil for butter for a dairy-free version.
- Make the bars gluten-free with a certified gluten-free flour blend and oats.
- Store leftovers in an airtight container in the fridge for up to 5 days.
- Bars can be frozen for up to 3 months. Thaw overnight in the fridge.
