Ingredients
Equipment
Method
- Line an 8×4-inch loaf pan with parchment paper (leave overhang for easy removal) or grease lightly with cooking spray.
- In a medium skillet, add blueberries and water. Simmer over medium heat for about 7 minutes, gently pressing down on half of the berries to release juices. Remove from heat and let cool slightly.
- In a large mixing bowl, stir together peanut butter, maple syrup, coconut oil, rolled oats, and oat flour until combined. The mixture should stick together when pressed.
- Spread ⅔ of the oat mixture evenly into the prepared loaf pan and press firmly.
- Spoon the blueberry mixture on top, spreading evenly but leaving a slight border around the edges.
- Crumble the remaining oat mixture over the blueberries and press lightly.
- Place the pan in the fridge for at least 2 hours (or overnight) until set. Slice into bars and enjoy!
