This isn’t quite the same as some of the other mug cakes I’ve made in the past. I didn’t create a recipe that can be made into one single serving, but it’s still delicious and easy and you can always store the leftover batter for later.

I was making a batch of our favorite baked donuts and I had some leftover batter and I decided to stick it in a mug and see if it would turn out okay. And it did! A minute and half later I was treated to a fluffy donut mug cake. Much quicker than making mini donuts in the oven.

The donut taste is similar to cake donuts and comes from the mini donut muffin recipe that’s been widely shared on the internet.

Even though this doesn’t make just one single serving, you can refrigerate the rest of the batter for later. Or you can make a few mug cakes rather than having to take the time to make mini donuts or mini donuts in the oven. If you’re impatient like me, being able to eat the donut cake in one minute rather than 10-15 is a definite plus.

I wasn’t quite sure how to decorate them so I drizzled chocolate ganache, which is what I use for my mini donuts. Now I kind of wish I added some sprinkles, especially when I added the little mini donut top hat.

Donut Mug Cakes


3/4 cup sugar
1 large egg
1 1/2 cups all purpose flour
2 tsp baking powder
1/4 tsp salt
1/4 tsp ground nutmeg
1/4 cup vegetable oil
3/4 cup fat free milk
1 tsp vanilla extract

For the chocolate ganache:
4 oz bittersweet chocolate, chopped
1/2 cup heavy cream


1. In a large bowl, whisk together sugar and egg until combined. Add in flour, baking powder, salt and nutmeg. Then mix in vegetable oil, milk and vanilla extract. Mix until batter is smooth.
2. Fill an oversized mug about 1/2 full with batter. Cook in microwave for about 1 minute and 30 seconds. Careful not to overcook or cake will become hard. If cake is puffy and toothpick inserted comes out clean, then it is done. You can repeat with remaining batter or store batter in fridge for later use.
3. While donut mug cakes are cooling make the ganache. Heat heavy cream microwaveable glass cup for about 40 seconds in microwave. Pour heavy cream into bowl of chopped chocolate. Stir and mix until chocolate is completely melted and smooth.
4. Let ganache cool for a few minutes before drizzling over donut mug cakes.

    all these recipes have no microwave wattage,
    what was the wattage used to make these?

    • Kirbie replied: — June 25th, 2012 @ 8:40 am

      That’s one of the reasons the time is an approximation because it will vary depending on your microwave. I have a 1000 watt microwave, which I believe is pretty common.

    approx how many mug cakes does this recipe yield?

    • Kirbie replied: — June 25th, 2012 @ 12:53 pm

      I don’t know the exact number, and of course it would also vary depending on your mug size. Like I mentioned in my post, I put in some leftover batter from donuts I was making, so I didn’t try using this batter exclusively for just making the mug cakes. But I would estimate that you can get about 6-8 mug cakes from this batter. Hope that helps!

    Um.. I was wondering if I could shape the batter into other shapes, will it stay the same shape while it is being microwaved? And if I use a microwaveable bowl instead do I still microwave it for 1 1/2 mins?

    • Kirbie replied: — October 6th, 2013 @ 7:18 am

      The batter will be too wet to shape. It should be the same amount of time in a bowl.

    1, 2, 3, BAKING POWER! (sorry- noticed the typo, and couldn’t help it! ) :)
