Baked oat muffins with whey protein taste like a real muffin but actually deliver meaningful protein. Snack without the guilt, fuel without the crash.
Preheat the oven to 350°F and line a muffin tin with paper liners.
In a mixing bowl, combine the oats, whey protein powder, baking powder, cinnamon, and salt, stirring thoroughly to distribute dry ingredients evenly.
Mash the ripe banana and whisk together with eggs, almond milk, maple syrup, and vanilla extract until smooth for moist texture.
Add the wet mixture to the dry mixture, stirring gently until just combined; avoid over-mixing to retain muffin fluffiness.
Divide the batter evenly among the muffin cups, filling each about 2/3 full, then bake for 18–20 minutes until tops are golden and a toothpick inserted comes out clean.
Let muffins cool in the tin for 5 minutes to set structure, then transfer to a wire rack to finish cooling completely before serving.
