Peanut Butter Chocolate Mug Cake

I am off of work today. I am on summer vacation aka – maternity leave. Oh, you didn’t know I was pregnant? Then I guess you don’t follow us on Facebook. I look forward to sleeping in, laying by the pool, and baking cupcakes all summer. Why are you laughing? In all seriousness, I was due, oh about 4 days ago, so we should be welcoming a baby any time now. While we wait, I am just going to lay on the couch, read, and maybe make those cupcakes. Cliff has a fun nursery decorating post coming up soon. I like to call him Martha Stewart; he is so crafty! So, if we disappear sometime next week, now you will know why.

Well, today is the last day of our mug cake week. I hope that you all were making mug cakes for dessert every night. Sorry if we ruined your summer body diet! I really liked all the cakes we made this week. And who could possibly say no to a peanut butter and chocolate cake that can be made in 3 minutes. Does it get any better. Talk about instant gratification. Is there any better pairing than peanut butter and chocolate? If there is, I can’t think of it. I hope you had as much fun making/eating your mug cakes as we did!

For the Cake

  • 4 tbsp self rising flour
  • 4 tbsp sugar
  • 1 egg, whisked
  • 3 tbsp cocoa powder
  • 3 tbsp milk
  • 3 tbsp vegetable oil

For the Topping

  • 1/4 cup heavy cream
  • 1 tbsp sugar


  • Combine all ingredients for the cake right in the mug.
  • Stir together well.
  • Microwave for 1-3 minutes. We found it best to microwave for 1 1/2 minutes and then 30 second intervals until it was no longer gooey.
  • Allow the cake to cool. While the cake is cooling make the whipped cream topping.
  • Whip the heavy cream and sugar in a stand mixer until stiff peaks form. Spoon over cooled cake.
  • We sprinkled the cake with a little cocoa powder for garnish as well.
