How to Make

  2. In a one-cup capacity, microwave-safe mug, whisk together the dry ingredients.
  3. Whisk in the wet ingredients, then the chocolate chips.
  4. Microwave for about 45 seconds or until risen and the top is firm, though it’s OK to have the very center look underdone.
  5. Remove and let cool a minute or two before topping with ice cream, whipped cream, berries, etc.

Expert Tips

  • Always make sure your mugs are microwave-safe and hold a cup or more of liquid.
  • Check to see if your baking powder (different from baking soda) is active. Spoon some into a cup of hot water and stir. It should bubble vigorously. If it does not, replace it before proceeding with the recipe.
  • Do not overfill your mugs.
  • Do not overcook or the cake will be dry and/or spongy.
  • Test with the least amount of time if given a range. You can always cook a few seconds longer.
  • Make sure to garnish with ice cream or sweetened whipped cream for the ultimate mug cake experience!

Frequently Asked Questions

Do Mug Cakes Really Work?

Yes! Though they will never be quite the same as a great homemade cake recipe made from scratch. As long as you measure correctly and use fresh baking powder, they work well. The timing may vary depending on the wattage of your microwave.

Are Mug Cakes Bad for You?

As long as they’re properly cooked so any possible bacteria in the flour or eggs is rendered harmless, mug cakes are no worse for you than any other cake.

How Do You Make Mug Cakes Better?

If you have not liked previous mug cake recipes you’ve tried, try one with egg and chocolate chips. Both add some fat which provides richness. Also, don’t overcook. Try the lower value in the range of times. You can always cook longer.

Adpated from Gemma's Bigger Bolder Baking. Gemma used a small egg, but I didn't want to purchase a whole carton. You may use a small egg, whisked, instead of 3 tablespoons.

Check the expiration date on your baking powder. It often expires before you can use it all. To test, put a spoonful in a cup of very hot water. If fresh, it will bubble vigorously.
