Heat oven to 350 degrees. Put 4 paper liners in either cupcake tin or silicone cupcake molds on a cookie sheet. Spray with vegetable oil spray, if desired.
In a small mixing bowl (or cereal bowl) stir together the dry ingredients: almond flour, sweetener, salt, xanthan gum, and baking powder.
Add all the wet ingredients: melted butter, cream, vanilla extract, vanilla, imitation butter flavoring (opt) , and egg.
Stir all ingredients until thoroughly mixed and not lumpy.
Divide batter evenly into 4 previously prepared cupcake liners. Place in oven and bake 14-16 minutes. (Tops of cakes will be light colored, but lose their glossiness when cupcakes are done.)
