50gNutella spread or Vego spread (for the dairy free/vegan option)
40-60g(2-3 tablespoons)* boiling water American, UK and NZ readers: use 1 tablespoon + 1 teaspoon. Your tablespoons are 15ml whereas ours in Australia are 20ml. 1 tablespoon + 1 teaspoon = 20ml.
Instructions
Whisk the dry ingredients together in a small bowl, then add the Nutella or Vego spread.
Add the boiling water a tablespoon at a time until you reach a glossy and smooth medium consistency batter. You might need to adjust the water if you try other flour combinations.
Microwave the mug cake for 90 seconds - 1 minute. I like to underbake mine slightly so there's an inbuilt sauce. Allow the mug cake to cool for a minute or two before topping with ice cream and serving.
