Pre heat your oven (for me i used mawe tatu), grease Your baking tin.

Mix the dry ingredients flour plus baking powder, then now mix sugar and margarine and beat until soft then add your eggs one by one while.

Add the orange essence and mix,then bit by bit add your flour with mix as your mix until the cake batter is ready.

Place your batter in a baking tin and bake it until ready if not use a toothpick and insert in the middle to check.

For the icing I used buttercream (nyambura mukururi recipe).
