01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease.
02 - In a large mixing bowl, whisk together whole wheat flour, protein powder, baking powder, baking soda, ground cinnamon, nutmeg, and salt until evenly blended.
03 - In a separate bowl, beat eggs thoroughly. Add ricotta, honey, milk, melted coconut oil, and vanilla extract; mix until smooth and cohesive.
04 - Add wet ingredients to dry ingredients and gently fold together until just combined. Avoid overmixing to preserve muffin texture.
05 - Fold in grated carrots evenly. If desired, gently stir in chopped walnuts or pecans and raisins.
06 - Distribute batter evenly among the prepared muffin cups, filling each about three-quarters full for optimal rise.
07 - Bake for 22 to 25 minutes, or until a toothpick inserted into the center emerges clean.
08 - Allow muffins to cool in the tin for 5 minutes, then transfer onto a wire rack to cool completely.
