Preheat oven to 350 degrees F. Line a large baking sheet with parchment paper and set aside.
In the bowl of a stand mixer, add in vegan butter, applesauce, sugar, maple syrup, flax egg, vanilla and almond extract. Process for 30 seconds-1 minute until well combined.
Next, add in almond flour, coconut flour, baking powder and salt. Mix until a dough forms.
Use your hands to roll the dough into golf ball sized balls (about 1.5 tablespoon per cookie). Place on prepared cookie sheet then flatten each dough ball (until about ¼-1/2 inch thick) with the bottom of a glass. Tip- flour the bottom of the glass between cookies to ensure it doesn't stick!
Bake for 10-12 minutes. Remove from oven and allow cookies to cool completely.
To make the frosting- beat together all ingredients (butter, icing sugar, vanilla and colouring) on high until smooth. Frost each cookie and sprinkle with coloured sprinkles.
