Pre-heat the oven to 325*F.
In a large bowl, beat together the butter and sweeteners until light and fluffy (~2 minutes).
Add the egg and extracts and beat again until combined.
In a separate bowl, whisk together the almond flour, coconut flour, shredded coconut, slivered almonds, baking soda, xanthan gum and salt.
Add the dry ingredients to the wet and stir until a thick batter forms.
Line cookie sheets with parchment paper and roll the batter into small balls. Flatten each ball slightly and sprinkle the top with additional slivered almonds and shredded coconut if desired.
Bake the cookies for ~8-9min. The edges should be lightly browned.
Let the cookies cool FULLY on the tray before trying to remove them. They will firm up and hold together once cooled.
Serve with a glass of coconut or almond milk and enjoy your Keto Coconut Almond Cookies!
