Hi Bold Bakers!
When it comes to a mug cake recipe, I have tried them all. From Bold flavors like my Funfetti Mug Cake to a Microwave Mug Brownie, I pride myself on having created almost 100 Mug Recipes for you. Now I’ve taken my Mug Meals magic to the next level by creating mug cakes that can be prepared in advance!
My Microwave Sponge Cake in a Mug is one of my new favorites. The beauty of this recipe is you will never have to worry that your sweet tooth will go unsatisfied again with a microwave cake you can make in minutes.
How Do You Make Mug Sponge Cake?
My Microwave Mug Sponge Cake could not be more authentic. Made from all the usual suspects for cake recipes — like butter, flour, sugar, vanilla and almond extract — this lovely sweet cake with that special soft texture is the perfect end to any day.

Now instead of making a whole cake you can have just 1 serving in no time at all. And this cake batter can sit in its little mug in the fridge for up to 3 days, so you can enjoy a single-serving treat anytime!

How Long Does Mug Sponge Cake Take To Cook?
Whenever I just need a little something sweet I pop this mug cake in the microwave for about 1 minute. I have to say the only thing more satisfying than cake, is cake cooked in minutes. I top off my lovely sponge cake just like I would a traditional one: with loads of whipped cream and fresh berries.
I can’t wait for you all to treat yourself to my Microwave Mug Sponge Cake!
