its for my sons 5th birthday, i hope to make and coat with rolled icing decorated with teenage mutant ninja turtles. i want a moist vanilla cake recipe that will hold up to stacking. i dont really like butter milk. Ive been using

8oz self raising

8oz caster sugar

8oz sunflour marg/spead

4 eggs

vanilla extract

It is nice but not as yummy moist as I would like.
