Cocoa powder, Remove 50grs of plain flour and substitute 50grs of cocoa powder. Trust me it works


Lemon cake - I would start with 1 teas, of extract you can always add more if required, I would also add the zest of 1 unwaxed lemon, but not lemon juice, this would alter the constistancy of the cake mix
I don't know grams, but in cups you would add 1/2c of cocoa powder.





For the lemon, a teaspoon should be good. The same you would use if it were a vanilla.
For the chocolate cake you need to add cocoa powder, not powdered chocolate. About two heaped tablespoons, and a drop or two of milk to bring the mix back to the right consistency.





For the lemon cake I would personally use lemon zest rather than essence. Using a fine cheese grater, take all the yellow skin from a lemon which you have washed in hot water (to remove the wax which is put on lemons to help them keep) and cooled again. Make sure you don't get any of the white bits in the zest - it is bitter. Use the zest of half a lemon, and squeeze some of the lemon juice in too.





Good luck
