Mug cakes. I have a love/hate relationship with them. Love because they are so stinkin’ delicious, and hate because I want more. But that is the whole reason to make a mug cake, isn’t it? So you don’t pig out on an even bigger dessert? That’s mine, anyway.
Another popular reason is because they take such a short amount of time to make, especially if you want one serving . . . no going through the motions to make an entire cake. You avoid messy cleanup. And you can raid your cabinet for ingredients as opposed to driving to get something sweet. I love it.
What is a Mug Cake?
It’s is a single serving cake made in a ceramic mug and then cooked in the microwave. That’s it! The whole purpose is that you can make a quick dessert with ingredients you likely already have AND that you can do it without an oven.
How to Make a Mug Cake
This is where you get to raid your cabinet and see what you have to make your mug cakes. You’re always going to need the following ingredients so I recommend having them on hand should the need for sweets arise:
- Baking powder (if you don’t use self rising flour)
- Salt (enhances the flavor)
- Flavoring – vanilla, cocoa powder, cinnamon
- Butter or oil
There are other optional ingredients as well such as eggs, milk, buttermilk, vinegar, and then toppings. Some mug cake recipes even use cake mix.
Besides ingredients, you’ll obviously need the mug and then a microwave. Mug cakes are made in a microwave and not in the oven. There’s no specific kind of mug you need to use – just one that is microwave safe.
Basic Mug Cake Recipe
Are you wondering how to make the best mug cake ever? I have a basic recipe for you below, with two variations (vanilla and chocolate). You’ll use this base recipe and then experiment from there.
- 2 T butter
- 1/4 cup all-purpose flour
- 2 T granulated sugar
- 1/2 T baking powder
- 1 T milk
- 1 pinch salt
For Vanilla Cake
- 1 tsp vanilla extract
For Chocolate Cake
- 2 T unsweetened cocoa powder
- 2 T chocolate chips
- Place the butter into your mug and microwave about 30 - 40 seconds or until just melted.
- Add remaining ingredients - choosing between a vanilla or chocolate cake. Mix well with a fork.
- Microwave 60 - 90 seconds. Start with 60 seconds and then check. You'll know it's done when the cake starts to pull away from the sides of the mug and the top is dry.

Now that you know the basics, let’s move onto some tips!
Tips for Making Mug Cakes
- Don’t overfill the mug. Fill the mug halfway up at most so that the batter doesn’t spill over the sides when cooking. Grab a bigger mug if you need to!
- Microwave the shortest time the recipe calls for to start. The cake should start pulling away from the sides and the top should look somewhat dry and be spongy. If it’s not, keep going at 15-second intervals until it’s done.
- Small to medium eggs are best for a single size (if your recipe calls for them). If you only have large eggs, either make two cakes (double the dry ingredients) or just use the yolk.
- Don’t worry about looks. Your cake is probably going to sink somewhat, and that’s okay. Mug cakes typically don’t look like the pictures because those are styled for a photo shoot. The point is that your cake in a cup is delicious!
I often get asked about substituting ingredients in mug cakes, and here are some common themes:
- If you don’t have self rising flour, you’ll need baking powder. If you don’t have baking powder, use 1/4 the amount of baking soda. But then I would also substitute the milk (or add) with buttermilk, sour cream, or yogurt. You need something acidic to making the baking soda work and make the cakes rise.
- If you don’t have an egg, find a recipe that doesn’t contain an egg (there are many). OR try 1/4 cup applesauce.
- Cake mix is great if you have a box of it and don’t want to use it for an entire cake. In fact, you can keep a box of cake mix on hand and make your own mug cakes on the regular, when you get a craving! Visit our pumpkin spice recipe as an example.
Topping for Mug Cakes
There are a lot of things you can put on the top of mug cakes, but here are my favorite options:
- Whipped cream
- Decorative sprinkles
- Powdered sugar (best on chocolate)
- Cream cheese frosting (1.5 oz cream cheese, 1/8 c confectioner’s sugar, 1/4 tsp vanilla, 1/2 T milk)
- Glaze (1/8 c confectioner’s sugar, 1/4 tsp vanilla, 1/2 T milk)
- Marshmallow fluff
- Chocolate chips (white, dark, or milk)
- Sugar/cinnamon (1 T sugar, 1/4 t cinnamon)
Just about anything sweet will work. Are you READY for some RECIPES??
