Taste and texture:

This homemade chocolate mug cake is rich, fudgy and chocolatey. It tastes like a dark chocolate brownie. It is never dry, but is so moist and decadent. It's perfect if you have a sweet craving and is the fastest way to make a chocolate cake that I know of.

Key ingredients and substitutions:

You should be able to find all of these basic ingredients at any local grocery store. For the exact measurements refer to the recipe card at the bottom of the post.

  • Cacao powder - cacao powder is what gives this mug cake that delicious, dark chocolate flavour. Instead of cacao powder you can use cocoa powder.
  • Egg - one egg is used to bind the ingredients in this cake together and help it rise when it cooks in the microwave.
  • Maple syrup- maple syrup is used to naturally sweeten this delicious chocolate cake and keep it refined sugar free.

Step-by-step instructions:

Step one:

First, put the dry ingredients and wet ingredients into a large, microwave-safemug.

Step three:

Place the mug in the microwave and heat it on high heat for approximately 60-70 seconds (until it puffs up and has a cake-like consistency).

  • I recommend using a large mug to make this gluten-free mugcake. If you use a short mug it might overflow when you cook it.
  • Be sure to use a microwave-safe mug for this cake. Otherwise the mug might break or explode in the microwave.
  • Be sure to stir or whisk the ingredients well so there aren't any clumps remaining.
  • For best results don't cover the mug when you heat it in the microwave. If you do the cake ends up with more of a slimy texture or rubbery texture rather than a cakey texture.
  • Let the cake cool for a couple minutes before adding the caramel and peanut toppings. This helps give the cake the perfect cake-like texture.
  • Don't overcook this cake - if you cook it too long it will turn out more dry and crumbly rather than moist and fudgy.
  • Cooking time may vary depending on the type of microwave you use.

Variations and optional ingredients:

  • You can use cacao powder or cocoa powder to make this coffeemug cake.
  • Feel free to add a handful ofchocolate chips to make this into a double chocolate mug cake.
  • You could add some nuts such as chopped pecans or walnuts to give this mug cake even more texture.
  • You could add a teaspoon of vanilla extract to give this cake even more flavour.
  • Feel free to add a pinch of salt to the top of this chocolate cake. Salty chocolate is my favorite!

How to serve:

This mug cake is delicious served as is, but you could also top it with vanilla ice cream, whipped cream, coconut whipped cream, fresh berries, vanilla yogurt, chocolate sauce or even chocolate chips.

You could also top this easy mug cake recipe with creamypeanut butter to turn it into a chocolate peanut butter mug cake or Nutella to turn it into a chocolate Nutella mug cake.

How to store:

This 3 ingredient chocolate cakeis best served right away but you could cover it and store it in the fridge overnight. I don't recommend trying to freeze mug cake.
