These customizable protein muffins are perfect for busy mornings, post-workout fuel, or a satisfying sweet treat. Packed with protein and naturally sweetened with fruit of your choice, they’re a nutritious and convenient option. Plus, you can customize it with any protein shake, fruit, or mix-ins to suit your taste and dietary needs.
Preheat oven to 350 degrees. Line a 12-cup nonstick muffin tin with silicone liners or generously grease the tin.
In a large bowl, whisk together all ingredients. If using frozen fruit, don’t thaw — fold right into batter.
Scoop batter evenly into the prepared muffin tin, filling each cup about 3/4 full.
Bake for 22-30 minutes, or until a toothpick inserted into the center of a muffin comes out clean. (When we were testing this recipe, 22 minutes is typically perfect!)
Cool in the tin for 10 minutes, then transfer to a wire rack to cool completely before enjoying.
