1 TB of Erythritol = We use this
2 TB Melted Butter

Melt 2 Tblsp of butter in a large mug or small Pyrex dish or large mug

Add in the Almond Flour, Baking Powder, Cinnamon, Erythritol, Egg and mix well.

Microwave on high for 90 second. The mug cinnamon roll will puff up and pull away from the sides of the mug.

When the microwave beeps, use a fork to loosen the cinnamon roll (it will have pulled away from the sides, so focus on the bottom) then flip onto a plate.

Butter Glaze Instructions

Melt the butter for the Butter Glaze, then add the Cinnamon and Erythritol to it and mix well. Pour the glaze over the mug cinnamon roll for added sweetness, texture, and moisture.

Cream Cheese Instructions 

In the mug or Pyrex bowl, microwave the cream cheese for 30 seconds on half power, or until you hear the cream cheese start to crackle in the microwave. Add in the ½ Tblsp Erythritol  and mix well, then top your keto cinnamon bun with this cream cheese “icing”
