I spent a while looking up recipes on the Internet and cobbled this one together. Although it made a very nice moist almost fudgy textured tasty cake, it wasn't quite what we were after. But no one is complaining eating our efforts.
225g plain flour
1tsp bicarbonate of soda
2 eggs 125g butter
30g natural yogurt mixed with 100 ml milk
175 ml of dandelion and burdock drink
2 tbs cocoa powder sifted
beat the butter with the sugar until pale and fluffy, add in eggs one by one until combined.
sift together the flour, bicarb and cocoa powder and add a third, when combined add the yogurt/milk mixture. Then add third more of flour then carefully add the dandelion and burdock, which will make mixture looks curdled but it's OK honest. mix in the rest of flour mixture and pour into a greased lined 9 inch tin. Cook in preheated oven at gas mark 4 for 45-60 minutes until a cake skewer or small knife tip comes out of the cake clean.
