Preheat the oven to 350 degrees and line a baking tray with parchment paper.
In a medium mixing bowl, mix wet ingredients together (egg, maple syrup, vanilla, coconut oil) until smooth, then add in dry ingredients (almond flour, coconut flour, baking soda, salt) and mix until fully blended.
Scoop out 2-3 tbsp for each cookie and roll into balls and place on a baking sheet. Once all batter is used up, flatten the balls to 1 inch thick cookies and cook for 10 minutes.
While cookies are baking, puree the strawberries until smooth in a high speed blender or food processor.
Mix ¼ cup icing with 1 tbsp of puree, until you get a smooth strawberry icing.
Remove cookies from oven, let cool and then place strawberry icing in between two cookies creating a sandwich and ENJOY!
