Lemon-Vanilla sponge cake

So tomorrow is one of my lovelies birthday, and so I had in mind to bake him a surprise cake, and to also try one of the recipes, I've always thought of making for my self to enjoy all alone

LEMON VANILLA SPONGE CAKE
Baking time 45mins,1hr tops, as I don't have an oven yet

Ingredients
-750g of all purpose flour
-350g of sugar
-750g of margarine
-15 Large eggs
-Vanilla flavour
-3teaspoons of baking powder
-1/2teaspoons of excel sponge
-Rind of lemon
-Lemon juice
An easier method of getting the lemon juice from the lemon if you don't have a juicer , soak the lemon in a warm water before squeezing.

STEPS

• cream the margarine with sugar together in a mixer.
• Whisk the eggs and the excel sponge using hand mixer before adding it into the mixed butter and sugar.
• Measure and Sieve the dry ingredients(flour,baking powder), add it into the mixture of the margarine, sugar, eggs and the excel sponge. And then add the lemon rind, it's juice, and the vanilla flavour, mixing them thoroughly not longer with the mixer but with a wooden spoon or your hand, after it had been thoroughly washed.
• prepare your 8" round pan,make sure it is clean there after rub a bit of margarine in it , and dust it with some flour.
• pour the batter into the pan and straight away into the oven,set your time, so it doesn't get burnt.
• When a toothpick is inserted the cake and it comes out clean, then your cake is ready. Bring it down and turn it on a cooling rack or a flat plate or a tray.
