How to Make These High-Protein Apple Cinnamon Muffins
Making these high-protein apple cinnamon muffins is so simple, and your kitchen will smell irresistible while they bake. Here’s how to bring them together:
Make the crumble
Combine the dry crumble ingredients in a small bowl, then mix in the melted coconut oil until coarse crumbs form. Set aside while you prepare the muffin batter.
Mix the wet ingredients
In a large bowl, whisk together the applesauce, Greek yogurt, eggs, maple syrup, and melted coconut oil until smooth and creamy.
Add the dry ingredients
Stir in the protein powder, oat flour, baking powder, baking soda, cinnamon, nutmeg, and salt until just combined.
Fold in the apples
Gently mix in the chopped apple pieces so they’re evenly distributed throughout the batter.
Assemble the muffins
Fill each lined muffin cup halfway with batter, add a spoonful of crumble to the center, then top with the remaining batter. Finish by sprinkling the rest of the crumble evenly on top.
Bake and cool
Bake until golden and set, then let the muffins cool in the pan for a few minutes before transferring them to a rack. Enjoy warm or at room temperature.
