Blend all of the crepe ingredients (except the butter) together in a blender or magic bullet until smooth. Let the batter rest for 5 minutes. Heat butter in a nonstick pan on medium heat until sizzling. Pour enough batter into the pan to form a 6 inch crepe. Cook for about 2 minutes, then flip and cook for an additional minute. Remove and stack on a warm plate. You should end up with about 8 crepes. Meanwhile, mix your sweetener and cinnamon in a small bowl or baggie until combined. Stir half of the mixture into your softened butter until smooth. To serve, spread 1 Tbsp of the butter mixture onto the center of your crepe. Roll up and sprinkle with about 1 tsp of additional sweetener/cinnamon mixture.
