Nutella lava brownie mug cake

After I made the brownie mug cake which I absolutely love, I couldn’t help but wonder if I could do anything to improve on it.

So, of course, the first thing I thought was to experiment with Nutella. I’ve had Nutella lava brownies before and decided to try to do something similar. Since the brownie is enclosed in a mug, it’s hard to have a real lava flowing effect when you break into the cake, but you can create a liquid gooey center of Nutella that comes up with a spoonful of brownie.

I was worried that the Nutella might sink to the bottom, but it was thick enough to bake right in the middle of the brownie. From the outside the brownie looked the same. But dig in and you’re treated to a rich brownie plus some melty Nutella. This was soo good.

This brownie mug cake has gooey Nutella baked in the center. It's a decadent treat for two that takes only a few minutes to make!


  • 2 oz semisweet chocolate chips or chopped chocolate
  • 2 tbsp butter
  • 1 egg
  • 4 tbsp sugar
  • 2 tbsp flour
  • 3 tbsp Nutella


  • Select two microwave-safe mugs. In each mug place one tbsp of butter and 1 oz of semisweet chocolate. Microwave each mug for 40 seconds (microwave them separately). Remove and stir until chocolate is completely melted with a small fork.
  • Add 2 tbsp sugar to each mug and stir. Beat egg in a small bowl, add half to each mug and mix. Add in 1 tbsp flour to each cup and mix until smooth. Add in 1 1/2 tablespoons of Nutella into the cup, trying to center it in the middle of the batter (you don't need to squish down as the Nutella will start to sink and the cake will rise over it when baking.
  • Cook each brownie for 1 minute in microwave (do each separately). Serve while warm.

  1. I love these cakes, over time this one has become my go to. To cut back a bit on calories/sugar I have cut the amount of sugar and Nutella in half and it is still plenty sweet. These are perfect for those cravings without having a whole tray of baking in the house tempting you, thank you very much!

  2. If anybody is finding it too sweet , you could replace the nutella with pb or use 1/2T nutella and 1T pb. It tastes better than the choc-pb cake. Also using 3T flour and sugar makes it a bit firmer but it still works if you don’t have/want to use pb.
