In a large mixing bowl, cream the sweetener and softened butter. You can use a wooden spoon for this or an electric mixer.
Add the egg and vanilla to the butter + sweetener mixture.
In a separate bowl combine the dry ingredients: almond flour, coconut flour, pumpkin pie spice, golden monkfruit sweetener, salt, and baking powder.
Add the dry ingredients into the bowl of wet ingredients and mix thoroughly until a smooth dough forms.
Wrap prepared dough in parchment or wax paper and chill for 45 minutes or longer.
After the dough is chilled
Preheat the oven to 350F. Line baking sheet(s) with parchment paper.
Roll out chilled dough between to layers of wax paper or parchment paper.
Use small cookie cutters for the shapes of these cookies. Alternatively, you could use a pastry rolling cutter and cut these into 1" x 2.5" cookie bars.
Bake on parchment paper or silicone mat for 12-14 minutes.
Move cookies to a cooling rack until completely cooled.
If you are using chocolate chips, place one on each cookie and allow it to melt then spread it across the cookie either using the back of a spoon or by "sandwiching" two cookies together.
