Preheat the oven to 350° F.
In a bowl, combine the dry ingredients and set aside.
In a smaller bowl, melt the coconut oil, then add in the maple and vanilla and stir.
Pour the liquid ingredients into the dry ingredient bowl and mix until fully combined and a dough forms.
Roll into 12-14 balls. One by one, flatten each ball with your hand and using your thumb, create a well in the middle to allow for the sun butter after baking.
Bake for 10 minutes, until beginning to brown slightly (the bottom will be golden).
Allow cookies to cool completely and then fill each well with ½-1 teaspoon of sun butter. The amount depends on how deep the the hole is and how sun buttery you want your tagalong.
Freeze the cookies until the sun butter is firm to the touch -- this will take several hours.
