How to Make It
Preheat oven to 350°F. Grease a 12-cup muffin tin with cooking spray.
Stir flour, baking powder, baking soda, salt, nutmeg, carrots, and walnuts in a large bowl until combined. Create a well in the center of bowl, and add melted butter, honey, and eggs. Stir until well combined. Spoon batter into prepared pan.
Bake until a wooden pick inserted in center comes out clean, about 18 minutes. Let cool in pan for 5 minutes. Remove from pan and cool completely on a wire rack.
