What you will need

This recipe uses 4 simple ingredients that you can find at any grocery store:

  • 4 tbsp Nutella
  • 1 large egg
  • 2 tbsp all purpose flour
  • 0.25 tsp salt

Step by step instructions

Step 1: Combine the Ingredients

Add the Nutella, egg, flour, and a pinch of salt to a large microwave safe mug and stir everything together vigorously with a fork until the batter is completely smooth with no streaks.

Step 2: Microwave the Cake

Place the mug in the microwave and cook on high power for 60 to 90 seconds. Start checking at 60 seconds as the top should look just set but the center can still appear slightly moist since it will continue cooking from residual heat.

Step 3: Cool and Serve

Allow the mug cake to cool for about 1 minute before eating directly from the mug. Be careful as the mug will be very hot and the cake inside will be steaming.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • Nutella → any chocolate hazelnut spread or peanut butter chocolate spread
  • all purpose flour → almond flour for a lower carb gluten free version

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Overcooking the mug cake which makes it rubbery and dry since it only needs 60 to 90 seconds and continues cooking after the microwave stops
  • Using a mug that is too small causing the batter to overflow during cooking so always use a mug with at least 12 ounce capacity
