I also add 3tsp of coffee dissolved in a little water.
Mix thoroughly and then, using a loose bottom 8-9 in. round tin, bake in oven at gas mark 6 for 30mins.
I use generous spoonfuls of everything. It rises beautifully and makes a tasty treat which is Dukan friendly.
Divide into 8 and freeze to keep it fresher though it will keep in the fridge on an air tight tin. Should be about 1tolerated per slice. Enjoy.
