1In a bowl combine 1/4 cup of flour, 2 tablespoons of sugar, 2 tablespoons of cocoa powder and 1/4 teaspoon of baking powder.
2Add 1/4 teaspoon of vanilla extract.
3Add 2 tablespoons of melted and cooled butter and 1/4 cup of milk.
4Get this combined and incorporated; a fork should work fine enough or you could use a small whisk.
5Now transfer this into a large microwave safe mug.
6Put a few chocolate chips on top.
7Take a teaspoon of Nutella and poke this right down into the center so that the chocolate cake batter is covering the Nutella and the chocolate chips.
