Baked Berry Protein Oatmeal Squares

Preheat your oven to 350°F (175°C) and lightly coat a 9x9-inch baking pan with cooking spray.

In a large mixing bowl, combine 2 cups rolled oats, 145 grams vanilla whey protein powder, 1 tsp baking powder, a pinch of salt, and 35 grams coarsely chopped walnuts.

In a separate medium bowl, whisk together 5 large eggs, 1 cup milk, and 1 tbsp honey until the mixture is completely smooth and the honey is incorporated.

Pour the wet egg and milk mixture into the dry oat mixture and stir with a spatula until all the oats are moistened and no dry protein powder remains.

Gently fold in 1.5 cups fresh blueberries, being careful not to crush them so the batter doesn't turn purple.

Transfer the mixture into the prepared baking pan, using a spatula to spread it evenly into the corners and smooth the top.

Bake for 30 minutes in the center of the oven until the center is firm to the touch and the edges have turned a light golden brown.

Remove the pan from the oven and let it sit for 10 minutes to cool and set completely before slicing into 5 equal squares.
