A fluffy and easy chocolate mug cake that can be made in approximately 5 minutes, without the help of an egg. All you need are the ingredients, a mug, and a microwave. Top with whatever you’d like!


  • 2 tbsp cocoa powder
  • 1/4 cup flour (all-purpose, oat, buckwheat, 1:1 GF, whole wheat)
  • 1 1/2 tbsp granulated sugar
  • 1/2 tsp baking powder
  • 1/8 tsp salt
  • 2/31 tbsp oil
  • 1/4 cup milk 
  • 1/2 tsp vanilla
  • 12 tbsp chocolate chips


  1. In a mug, mix together the dry (cocoa, flour, sugar, salt, baking powder).
  2. Then, mix in the wet (oil, milk, vanilla, chocolate chips).
  3. Top with more chocolate chips if you want, and cook in microwave for around 1 minute. This time depends on your microwave. I would recommend cooking in 20 second intervals after the minute until the cake is cooked through.
  4. Let cool, and top with nuts, vanilla ice cream, frosting, whipped cream, homemade nut butter, or whatever you’d like!


*Results will vary depending on which type of flour you use. For the fluffiest/lightest mug cake, use all-purpose. If you would like to use almond flour, I recommend using less milk and oil.

For Vegan: Use plant milk & vegan chocolate chips (e.g. Enjoy Life Brand)

For Gluten Free: Use gluten free flour (GF 1:1 all-purpose, buckwheat, oat, almond, etc.) and gluten free chocolate chips (e.g. Enjoy Life Brand)

For Nut Free: Use a nut free flour and a nut free milk
