Yum. Needed these last night badly. To make them vegan get a box of this:
Pour mix into a bowl and stir in 1/2 tsp baking powder, 1/4 cup water, 1/2 cup oil and 3 TB ground flax seeds mixed with 6 TB warm water. Stir until lumps are gone and pour into a square baking tin. Bake at 350 F for about 30 minutes until toothpick comes out clean. Cool then cut into squares.
