Ingredients

4 tablespoons self-raising flour

3 tablespoons cocoa powder

3 tablespoons nutella

3 tablespoons skim milk

1 tablespoon raw sugar

1 tablespoon olive oil

1 egg

Method

Combine all ingredients in an oversized microwave safe mug. Whisk lightly with a fork until combined and smooth. Microwave for a minute watching as the cake rises in the mug, stopping if it is about to overflow and continuing a couple of times for 10 second intervals till cooked. [Don’t be tempted to overcook. The cake virtually finishes cooking in that first 1 minute rise]
