Mash the beans

• Rinse and drain the black beans, then mash them in a mug with a fork until smooth.

Mix the batter

• Stir in the cocoa powder, sprouted flour, sweetener and baking powder.
• Add the egg and milk and mix until you get a thick, even batter.

Add the molten centre

• Push the dark chocolate pieces into the centre of the batter so they stay hidden.

Microwave

• Cook in the microwave until the top is set but the middle is still fudgy.

Serve

• Let it cool for a moment and eat warm straight from the mug.
