WHAT YOU’LL NEED FOR THIS MUG CAKE RECIPE:
Butter – Salted or Unsalted
White Granulated Sugar
Milk
Vanilla Extract
All-Purpose Flour
Baking Powder
Salt – omit if using salted butter
Cinnamon Sugar – blend of white granulated sugar and ground cinnamon.
How to make Coffee Cake in a Mug:
Melt the butter in a mug.
Add the sugar and stir to combine.
Stir in milk and vanilla extract. Then stir in flour, baking powder, and salt (if using).
Sprinkle on half of the cinnamon sugar and give a quick stir – not enough to fully combine but just to make a big swirl. Sprinkle remaining cinnamon sugar on top of batter.
Microwave 40 seconds to 1 minute, until just set.
Allow to cool a couple of minutes and enjoy!
Can I make more than one coffee cake?
This recipe is written for one cake in a mug, but you can easily double it to make two! You can mix them up separately in two mugs or mix up the batter before adding cinnamon sugar, divide between two mugs, and then add the cinnamon sugar to both. It’s best to microwave them separately, though.
What size of mug should I use?
Any standard size coffee mug works! I used mugs that were at least 8 ounces to leave room for the cake to puff up and rise while ‘baking’. The most important piece is to use a mug that is microwave safe!
Do I need to grease my mug?
Because you eat the coffee cake right out of the mug, you do not need to grease. Although, if you want easier clean up you could spray with cooking spray before cooking. I do not grease and instead just soak the mug in some warm soapy water for a few minutes before cleaning to remove any cooked on cake.
