Preheat oven to 350°F and melt butter down that you are using for dough (4 TB)
Mix dry ingredients almond flour, coconut flour, sweetener, xanthan gum, salt, ground cinnamon, baking powder
Mix wet ingredients melted butter, egg, vanilla extract and monk fruit extract
Combine dry and wet by folding with a spatula such as video. Dough will get really thick. Too thick for a hand mixer.
Oil 2 sheets of parchment paper and lay dough down on top of the oiled side.
Lay other half with oil side down on top of dough the being rolling into a rectangle shape. A tip I would cut off pieces to form a rectangle shape then just rolled them back down into the dough.
Don't roll dough too thin. If dough is sticking to the paper you have rolled too thin
Spread softened butter leaving about an half an inch at the end. Then sprinke cinnamon and sugar across after you have mixed those 2 together.
Being your roll, slowly
Cut into pieces and make sure the end piece isn't hanging. A little pressure will cause the dough to stick to itself easily. Spread out on the baking sheet.
Bake for 20-25 minutes in preheated oven. The tops will brown slightly but be mindful of the bottoms.
