I know I crave yellow cake often but I don’t want to make a whole batch – and that’s when this recipe is perfect.
Ingredient Notes
I cut this recipe down from my traditional birthday cake recipe – all the math is done for you! If you love a single serving cake (like my chocolate mug cake) this one is perfect for you.
- Egg Yolk: You only need half an egg, which I compensated for by using one large egg yolk. I tried it with the white and it didn’t turn out, so the fat in the yolk is needed for a soft and moist cake recipe.
- Vanilla Extract: Use a good quality to get that rich vanilla cake flavor.
- Flour: While I used all-purpose flour, you can also use gluten-free flour (the 1:1 AP flour). You’ll also need a pinch of salt and some baking powder.
- Butter: Like my cake recipe, this one starts with melted unsalted butter, although you can substitute vegetable oil to make it dairy-free.
- Milk: You can use any kind of milk (regular, fat free, low fat) or non-dairy milk (like almond milk).
How to make Vanilla Mug Cake
- While it might be easier to make the cake in the mug you’re cooking it in, I prefer to use a separate bowl.
- Whisk your dry ingredients, then stir the butter and sugar together and add the flour mixture to the wet ingredients.
- I always add sprinkles because they’re fun!
- You’ll need a microwave-safe mug or ramekin that is at least 7 ounces. The batter will rise as it cooks, so be sure that your vessel is big enough.
Expert Tips
- All microwaves cook differently so you might need less or more time. Once you make it a few times you’ll get to know how yours cooks.
- How do I know when it’s done? The cake is done when a toothpick inserted into the center comes out clean.
- Be careful not to overfill the mug! The batter will rise as it cooks, so leave some room at the top.
- The cake won’t fill a regular size coffee mug all the way to the top.
- The texture is as close to the real thing as you’re going to get with a microwave cake, but know it won’t be exactly like the real thing.
- Can you bake this cake in an oven? Yes, at 350°F for about 10-15 minutes.
