Microwave Mug Sponge Cake - Thee perfect single serve dessert that can be made in less than 5 minutes in the microwave

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!

Didn’t like the taste of the mugcake however making it was easy but was unsure on the wattage of the microwave too and was a bit eggy for my liking.

I baked it for 2 mins 20 seconds in the microwave and it came out PERFECTLY. Much love from South Africa.

Would it work if the flour in the recipe is completely substituted with almond and/or coconut flour? Basically looking for a complete vegan-gluten free way of making this. Thank you for sharing your creations..

Absolutely amazing!! Just made for my hubby. We had some frozen raspberries so I thawed and put on top and the juice on the bottom when I plated it. It was so good. He liked the plate!!

My 9 yr old daughter, Chandana absolutely loves your YouTube Channel. She keeps on surprising me by making these mug cakes and meals for me, for New year, for my birthday and for Mothers day. I really cant thank you enough for sharing such easy recipes with us all. God Bless You and hope you have a wonderful 2019 ahead!

PS: Its her birthday on March 18th and can you mention her name in any of your new videos. I am sure that would be a wonderful surprise for her. Her fav is cookies and cream 🙂

Cheers
Archana
