I had a craving for a sweet chocolate biscuit one night, and came up with these. The pieces of Mars Bar make chewy chocolate caramel chunks within the dough. I cooked mine for too long, and they’re more crunchy than I’d like, although the chewiness of the Mars Bars do contrast well with a crunchier biscuit.

1/2 cup butter
1 cup brown sugar
1 egg, beaten
1 tsp vanilla essence
1 3/4 cup self-raising flour
4 Mars Bars, chopped into small chunks

Preheat the oven to 180C. Beat the butter and sugar together until smooth. Beat in egg and vanilla. Stir in the pieces of Mars Bar – they’ll stick together, but a vigorous beating should separate them. Beat in the flour.

Blob the mixture onto greased baking trays with a dessert spoon, and bake for 8-12 minutes. Cool a little to firm.
