While other people hoard toilet paper and canned goods preparing for Coronavirus lockdown...I'm "social distancing" in the RV  just trying to figure out how to stretch the gluten free treats we have on hand. Tonight, its a MICROWAVE CAKE in just 10 minutes!

Who would have thought that making cakes in the microwave would be a thing? We stumbled across "mug cakes" years ago an have been hooked ever since. But, to make one for everyone means 5 messy mugs to wash and our kids don't really need an entire mug sized cake to themselves.

So I decided to try this made in one dish instead of 5 individual mugs. This microwave cake used half a boxed cake mix and made 6 small servings...just the right amount for a little sweet treat before bed. 

Give it a try and let me know how yours turns out!

The best part is you don’t even have to heat up the oven. That’s great in the summer.

Microwave Cake, What You'll Need:

I cannot vouch for other brands/flavors but just follow the directions on the box and cut everything by half.

For cake: 

1/2 a box of cake mix (I used Pillsbury gluten free Funfetti!) I did not measure and just estimated.

2 eggs

3 Tbsp butter, melted

1/2 cup water

For frosting:

1 1/2 cups powdered sugar

1/4 box of cream cheese

2 Tbsp softened butter

1/2 tsp vanilla/almond extract/etc

splash of milk (optional)


Mix all ingredients in a mixing bowl and stir until well combined.

I used a Pampered Chef Micro Cooker but you could also pour this into a microwave safe bowl and cover with a plate. 

Microwave cake on high for 5 minutes. The cake is done when a toothpick comes out clean. Microwaves (especially in RVs) vary. You may need to cook for an additional few minutes. 

I flipped my cake onto a plate and sat it aside to cool. 

While it was cooling, I mixed up a quick frosting. Any ol frosting will do but I love cream cheese icing. I softened the butter and cream cheese for about 30 seconds in the microwave, then beat them together with a whisk. 

Add in the vanilla, stir well. 

Add powdered sugar a little at a time, blending after each addition til smooth. 

If the frosting gets a little thick, give it a tiny splash of milk (like a tsp) and stir well. Repeat until you reach a good spreading consistency. 

Spread over cooled cake and top with sprinkles or whatever other topping you like!

Voila! If you've never had a cake made in the microwave...you're in for a surprise. It will transform your weeknight desserts! And the kids will be thrilled...and none the wiser!
