Ingredients
  

  • 200 grams rolled oats
  • 120 grams natural peanut butter
  • 50 ml maple syrup
  • 1 large egg
  • 50 ml milk dairy or plant-based
  • 120 grams blueberries fresh or frozen
  • 1 teaspoon baking powder
  • Pinch of salt
  • 20 grams of chopped peanuts or walnuts optional
  • Powdered sugar for dusting after baking optional

Instructions
 

  • Preheat the oven to 180°C (350°F) and line a small baking pan (about 20 × 20 cm / 8 × 8 inches) with parchment paper.
  • In a medium bowl, whisk together the egg, peanut butter, maple syrup, and milk until smooth.
  • Stir in the rolled oats, baking powder, and salt until everything is evenly combined.
  • Gently mix the blueberries into the batter so they are evenly distributed.
  • Transfer the batter to the prepared pan and spread it evenly, pressing lightly to level the surface. Sprinkle chopped nuts on top if desired.
  • Bake for about 25–30 minutes, or until the edges are lightly golden and the center feels set.
  • Cool completely before slicing into squares. Dust lightly with powdered sugar if desired.
