Preheat oven and Prepare Cake Mix according to Directions.
Coat the inside of the Mugs with Nonstick Cooking Spray.
Fill Mugs halfway with prepared Cake Batter - place mugs onto a cookie sheet.
Follow baking directions on the cake mix box. Begin checking your cakes at the time allotted for cupcakes. Cakes are done when a toothpick inserted into the center of one comes out clean or with just a few crumbs.
Allow the cakes to cool for about 30 minutes.
Top with Marshmallow Creme.
Serve in cup with a spoon - yummy!
- This would be too cute decorated with red and pink sugar sprinkles, or conversation hearts... let your imagination be your guide after all, it's Valentine's Day!
