Don't be nervous about using beetroot in these cupcakes. They help make a rich chocolate batter and there is just a faint, sweet earthiness.

The Method

Pre-heat the oven to 180°C/350°F/Gas Mark 4 and line the bun tray with paper cases.

Melt the chocolate in a bowl over a pan of gently simmering water and then stir in the puréed beetroot.

In a large bowl, using a hand mixer, beat the sugar and butter until light and fluffy. Whisk in the eggs, one at a time, until incorporated. Mix in the flour, baking powder, milk and the chocolate and beetroot mix.

Divide the batter evenly among the paper cases and bake in the oven for 15-20 minutes, or until firm. Allow the cupcakes to stand for a minute before transferring to a wire rack to cool.

To make the chocolate frosting, beat the butter and vanilla extract together in a bowl until light and fluffy. Then, add the icing sugar and cocoa powder, a little at a time, to the double cream until it is all incorporated and the mixture is smooth.

Using a palate knife, frost the cupcakes when they are completely cool.
