Can You Bake Chocolate Cake in a Microwave?

If you’ve never made cake in the microwave this will be a real eye opener and you may not go back to turning your oven on during the Summertime ever again to bake one! It literally takes ONE minute to cook and let’s just say the kids LOVE it this way (ok I am partial to it myself too)!

First thing first, let’s head to the store to get what we need! When you head into Walmart you can see they are all set up for Summer grilling season! You may not have these two already that you’ll need;

1 container Kraft Real Mayonnaise (regular, not low fat variety) is what I use for this and our Mayonnaise Biscuits. Then you’ll need to pick up a box of Jell-O instant pudding mix (vanilla works best for this chocolate cake recipe, found in baking aisle).

Chocolate Mayonnaise Cake with Cake Mix

There’s a video down below so you can take a quick look at how we make it. Watch and then come back. Now that you have the general idea, let’s get to baking the best chocolate mug cake with mayonnaise! This is dairy free too so that is another plus.

Whether you want to make 2 microwave safe 9 inch cake pans full or make a bunch of mugs full you make the batter the same way.

Dairy Free Mug Cake Ingredients

• Box cake mix (chocolate flavor for this one)
• Eggs
• 1 cup mayonnaise and water are needed
• Use a large bowl to combine the chocolate cake mix with other ingredients
  • whisk is helpful if not using an electric mixer to get it smooth
• Cool Whip Frosting – Whisk together defrosted 1 Tub Cool Whip (found in the freezer section of Walmart near the frozen pie crusts) + pudding mix if you want to make the pudding frosting

How to Make Layered Chocolate Mayonnaise Cake

If you want to make two round layers you will need 2 pans or wait until 1 cools and then use the pan again. It is easier to just buy two of them. In a preheated oven at 350 degrees you can bake each in just 7-8 minutes believe it or not!! When toothpick inserted comes out clean you’re ready.

How to Bake Mayonnaise Cake in the Microwave

1. First you want to combine your boxed cake mix with 2 eggs, 1 1/4 cup of water, and 1 cup of Kraft Real mayonnaise. That is ALL you need to make your cake! Now get out a coffee mug (traditional size)
2. Fill mug about 1/4-1/3 way full (if more than that it will overflow). Unless you’re using a pan then lightly grease and lightly flour insides
3. Now….put your mug in the microwave (about 1/3 c. batter) with a paper towel underneath (to catch spills) and cook for 1 minute.

Make sure to watch it especially when you put the first one in to make sure they don’t overflow. If they are beginning to just pause the microwave, check on it and on your next one just put a bit less batter in.

It will rise high like in the video but typically won’t overflow if it’s only filled 1/4 of the way, then it will deflate and look like this when you take it out. This chocolate cake with mayonnaise recipe is seriously so easy and the moistest cake you will ever try!

You do not have to make the pudding frosting if you need a lactose free version but we loved it. My husband had to skip this step.

If you choose to use a round cake pan it cannot be metal obviously, silicone works well though. If the larger form is preferred let it cool on wire rack to room temperature to cool completely before adding whipped topping or chocolate frosting on top.

Jello Pudding Frosting

Now this is how you make Jell-O Cool Whip pudding frosting to go on top. I have made this for other cakes and it is seriously SO tasty and simple to do….the kids can help too. 😉

• Just combine 1 cup of cold milk with the package of Jell-O instant pudding and whisk together for a good minute or so.
• Then, empty the entire tub of Cool Whip together with your Jell-O mixture and you’re done!!!
  • You can just put a dollop on your cakes right then and there or if you are saving for later or want to make then swirly pretty then scoop the mixture into baggies, zip them shut and when you’re ready just squeeze them on top.
  • I put baggies in the refrigerator for a bit while I am cooking my meal to get them cold and they swirl better that way too.

This isn’t just great on your cake mix mayonnaise cake though, we have used it on top of all sorts of other goodies!!

Mug Cake No Milk

Now….enjoy yourself outside while you’re grilling. Eat some yummy food on the barbecue, and when you’re done the cakes will be already done.

Just grab the frosting you’ve made out of the refrigerator (it will be nice and chilled by now). Squeeze a dollop on top with a little fruit slices if you choose. Just wait for the Oooohhhhhhhs and Ahhhhhhs!!

Chocolate Chip Mug Cake

I like to put a few slices of fresh fruit on top of desserts I make and these fresh cherries I grabbed during my grocery trip were just the ticket for this dessert. They added a really nice touch and tasted delicious on top too!

If you only use half the batch of the best chocolate mug cake just cover it and put it in the fridge to make the next day too. Jump to recipe and when you love it come back to try these others below.
