Preheat oven to gas mark 4 or 180c. Prepare the cake/ loaf tin if necessary.
Select the butter and sugar, creaming this together. This should become very light and fluffy.
Sift together the flour and bicarbonate into the butter mixture, ensuring that it is well incorporated.
Whisk the eggs separately before adding them gently to the flour mixture.
Mix the cocoa powder with the milk, adding the dandelion and burdock drink once combined.
Stirthis into the flour mixture gently. The mixture may become ‘bubbly’ and may appear mousse like.
Pour the cake batter into the prepared tin. This should fill approximately ¾ of the tin.(Tip: Tap the tin gently to remove any air bubbles and for the mixture to settle) Bake the mixture at the centre of the oven for about 40 minutes, or until a skewer comes out clean.
Allow to cool, on a cooling tray/ rack. Wait until cool before adding the topping.
