Have you ever wanted to bake a cake and all you have is a microwave? Most people settle for a simple little mug cake, but I’ve got a Microwave Cake recipe that will get you a deliciously moist layer cake perfect for a little birthday get together. This post contains affiliate links.
What do you bake a microwave cake in?
You can make this cake using the usual 8 x 8 square baking dish. It’s always my go to for cakes and casseroles in the microwave. If you have 9-inch round silicone cake pans, you could also make this as a round layer cake.
Can you make a microwave cake from a box mix?
Yes! I have done this with both regular 15-16 oz cake mix boxes like Duncan Hines or Betty Crocker as well as with 9 oz boxes of Jiffy Golden Yellow Cake.
If you’re using the Jiffy Golden Yellow Cake mix, you’ll need one box per layer, so a two-layer cake will take 2 boxes. For the 15-16 oz cake mixes, you’ll just need one box for two layers.
Use the ingredients listed on the box for each cake mix. Plus, you’ll need instant pudding mix to keep it nice and moist.
You will need the larger size box of instant pudding, it will be 5-6 oz. I use vanilla for yellow cakes and chocolate for chocolate cakes. When using it for the 9 oz Jiffy Cake mixes, you’ll use 1/2 the package of instant pudding for each box cake. For the 15-16 oz cake mixes, you’ll add the whole box of instant pudding.
I also cut a piece of parchment paper to fit the bottom of the pan.
How do you cook a cake in the microwave?
I make each layer one at a time using the same pan, so they’ll all be the same exact size. I wrap each one in plastic wrap and put it in the fridge while the next one cooks.
When you cook the cake in the microwave, cook for about 6 minutes and then check the top of the cake. It should look dry with no wet batter, and it will be pulling away from the sides of the dish. I find my 1000-watt microwave does best with 7 minutes cooking.
I would recommend starting at 5 or 6 minutes and checking to make sure it’s done. Then, pop it in the microwave for 1-minute increments until it’s done.
How do you decorate a microwave layer cake?
This is totally up to you. You can make your own fresh buttercream frosting in a mixer or just buy store bought canned frosting. Unless it’s a very special occasion, I use store bought frosting.
From my experience with microwave cakes, I think Duncan Hines is the best frosting for them. When we used Pillsbury, it kept trying to slide off the cake, but Duncan Hines stayed put. However, I do like buying the Pillsbury prefilled pastry bags of frosting to decorate the top once the cake is completely frosted.
