Ingredients
  

  • 2 cups rolled oats (old-fashioned; use certified GF if needed)
  • 1 scoop vanilla or unflavored protein powder (about 25–30 g)
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 2 large eggs (or 2 flax eggs for vegan)
  • 1 3/4 cups milk of choice (dairy or plant-based)
  • 1/4 cup maple syrup or honey
  • 1 teaspoon vanilla extract
  • 1 1/2 cups mixed berries (fresh or frozen)
  • 2 tablespoons melted coconut oil or butter (plus extra for greasing)

Instructions
 

  • Preheat the oven to 375°F (190°C). Lightly grease an 8x8-inch baking dish with coconut oil or nonstick spray.
  • In a large bowl, whisk together the rolled oats, protein powder, baking powder, cinnamon, and salt.
  • In a separate bowl, whisk the eggs, milk, maple syrup, vanilla extract, and melted coconut oil until smooth.
  • Pour the wet mixture into the dry ingredients and stir just to combine.
  • Fold in the mixed berries (add frozen berries straight from the freezer—no need to thaw).
  • Spread the mixture evenly in the prepared baking dish.
  • Bake for 30–35 minutes, until the top is golden and the center is set.
  • Cool for 10 minutes before slicing. Serve warm as-is or with yogurt, milk, or nut butter. Refrigerate leftovers for up to 5 days or freeze individual portions for up to 2 months.
