I have a recipe for chocolate drop biscuits, very easy. Sorry this recipe is one my mum use to make when she had cakes stick or stale cake. No idea where it is from originally.
3 1/2 cups cake crumbs
1/2 tsp baking powder
1/2 cup cocoa
1/2 cup dairy free margarine
1/2 cup sugar
4 egg yolks
6 tblsp cold water
1 tsp vanilla
Place all the ingredients in bowl except water and mix until combined. Add enough of the cold water in to get the correct consistency.
Place tsp fulls onto your baking sheet and bake @ 180 for approx 10 mins.
