Very exciting news: June 5 is National Donut Day. Yes, a whole day devoted to that sweet, fluffy, circular dough we know and love. To celebrate, we’re combining our kids’ favorite treats into one glorious indulgence — the Donut Mug Cake. Made in just five minutes!
This special treat is rich and sweet, with the texture of a cake donut. It’s one of those wonderful treats: clever, simple, with minimal prep, and maximal adorability. No matter how long your day has been, no matter how you’ve entirely given up on being that “Pinterest mom,” this easy recipe is so, totally doable.
You’ve likely already got the ingredients in your pantry. Invite your tots to gather around the kitchen and stir up their own mini cake batters. With a little help from mom or dad, they’ll be ready to enjoy the treat in no time. My kids want me to tell your kids that “this recipe is epic.”
Here’s how to make these divine Donut Mug Cakes, with step-by-step photos to make the process extra snappy:
Start with a standard-sized coffee mug. (The recipe at the bottom of this post perfectly fits one regular mug.) Spray that mug with a little nonstick baking spray. And don’t panic if you get some splatters on the outside. It’s all good.
Mix up the chocolatey donut cake batter, and spoon it into that ready-prepped mug. Now microwave for about 60 seconds. This will raise your batter up a bit and make it firm enough to hold the “donut hole” center.
To get that donut hole? Here’s the trick: press a silicone wine stopper into the center of your cake (don’t worry, it’s microwave-safe). Now microwave for 60-90 seconds more, adding 30 second bursts of cooking if needed to cook the cake through completely. You’ll know it’s done because the center of the donut ring springs back when touched lightly.
With the donut cake out of the microwave, allow it to cool slightly before the grown-up gently pulls on the wine stopper, removing it from the cake.
Now it’s time to frost. Drizzle your icing over the top of your warm cake, then sprinkle and grab a spoon. You’re ready to serve and enjoy!
Don’t forget to serve it alongside a cold glass of milk (or almond milk, or whatever you love to sip).
Note from the kids: My tweens want me to share that this cake is extra delish when chocolate or caramel syrup is drizzled down inside the donut hole. It soaks into the cake and makes it extra gooey.
Not particularly sugar-free, but a perfectly fun little treat for Donut Day, eh?
Donut Mug Cake
- 4 tablespoons all-purpose flour
- 3 tablespoons melted butter
- 4 tablespoons sugar
- 2 tablespoons cocoa powder
- 1 tablespoon vanilla extract
- 1 egg
- 3 tablespoons milk
- 1/2 cup powdered sugar
- 1/2 tablespoon milk
- 1/2 teaspoon vanilla extract
- 1 drop red or pink food coloring
- rainbow sprinkles
- Spray a standard-sized coffee mug with nonstick baking spray. In a small bowl, whisk together flour, butter, sugar, cocoa powder, vanilla, egg, and milk. Spoon into the prepared coffee mug.
- Microwave the cake for 60 seconds on high, then remove and press the silicone wine stopper into the center of the mug. Microwave 60-90 seconds more, or as long as needed to set the cake — the center of the donut ring should spring back when touched lightly. Once done, remove the silicone wine stopper.
- To make the frosting, mix together powdered sugar, milk, vanilla, and food coloring. Add more milk, if needed, to make the texture of the frosting slightly thicker than maple syrup. Then spread the icing on top of the warm donut cake. Top with sprinkles. Serve and enjoy!
Note: We frosted our donuts with classic pink frosting, but any icing will do. Chocolate, marshmallow fluff, or even a slather of Nutella will work.
