What you will need

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

  • 4 tablespoons Nutella
  • 1 large egg
  • 2 tablespoons all-purpose flour
  • 1 tablespoon cocoa powder

Step by step instructions

Step 1: Mix Ingredients

Add Nutella, egg, flour, and cocoa powder into a large microwave-safe mug. Stir vigorously with a fork until completely smooth and no streaks of flour remain.

Step 2: Microwave

Microwave on high for 60 to 90 seconds until the brownie is just set on top but still slightly soft in the center. Check at 60 seconds to avoid overcooking.

Step 3: Cool and Serve

Allow the mug brownie to cool for 1 to 2 minutes before eating as it will be extremely hot. Top with a scoop of ice cream or a dusting of powdered sugar if desired.

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 slightly denser gluten-free version

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Overcooking the brownie in the microwave which results in a rubbery dry texture instead of fudgy
  • Using too small a mug which causes the batter to overflow during cooking
