Step 1

Prepare the Muffins:Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or lightly grease it.

Step 2

In a large bowl, whisk together the flours, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger.

Step 3

In another bowl, combine the granulated sugar, brown sugar, vegetable oil, applesauce, eggs, and vanilla extract until well mixed.

Step 4

Gradually add the dry ingredients to the wet ingredients, stirring until just combined.

Step 5

Fold in the grated carrots, zucchini, and apple.

Step 6

Divide the batter evenly among the muffin cups, filling each about 2/3 full.

Step 7

Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.

Step 8

Allow the muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Step 9

Prepare the Cream Cheese Frosting:In a medium bowl, beat the softened cream cheese and butter until creamy and smooth.

Step 10

Gradually add the powdered sugar and vanilla extract, beating until smooth and well combined.

Step 11

Assemble the Muffins:Once the muffins are completely cool, spread or pipe the cream cheese frosting over the top of each muffin.

Step 12

Optionally, garnish with additional grated carrots, zucchini, and apple for a decorative touch.
