Preheat the oven to 400 degrees F and line a muffin pan with parchment paper liners.
In a small bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
In a bowl, beat the butter and sugar for 2-3 minutes until light and fluffy.
Scrape the bowl down, then add the eggs, maple syrup, and vanilla, greek yogurt and applesauce and mix until fully combined.
While the mixer is on low speed, add your dry ingredients to your wet ingredients. Do not over mix.
Lastly, fold in the grated carrot and chopped apple until evenly incorporated.
Fill the muffin cups all the way up to the top.
Bake the muffins for 18-20 minutes.
Allow muffins to cool for a few minutes in the pan, then transfer them to a wire rack to cool completely.
Notes
*If making for your kids and you want to reduce the sugar, reduce both the coconut sugar and maple syrup to 1/4 or 1/3 each. If the batter seems too thick after you reduce it, add 1-2 tbsp of applesauce.
