For the Cream Cheese Frosting:
In a large bowl, beat the butter and cream cheese with an electric mixer. With the mixer on low speed, add the powdered sugar one cup at a time, until smooth and creamy. Mix in the vanilla extract.
For the Cake:
Pour the Foodstirs™ Organic Cinnamon Swirl Coffee Cake Minute Mug Cake into a microwave-safe mug. An 8 oz mug is recommended. Add 2 Tbsp. of hot water and stir with a spoon until well combined. Microwave on high for 1 minute or until fully cooked. Cooking time may vary based on the microwave.
Carefully, remove the mug from the microwave, using the handle. The mug will be hot. Let cool for one minute.
Spread a generous layer of the cream cheese frosting on the top of the mug cake. Starting in the middle of the cake and working your way out in a spiral, dust the top of the cake with cinnamon. The cake is best consumed warm. Enjoy!
