Baby and Child Cake (No added Sugar, All Natural)

One thing I am very aware is sugar with a child. Having a sweet tooth myself and seeing the damage sugar does, I am determined not the let my child have too much as all children are perfectly happy without (if they don't know the taste). On birthdays my 'rule' can be hard to stick too. However, I have made sugar free cakes with success for two birthdays now, and have received many comments on how people prefer my sugar free cake to the normal cake mixture

Here is my recipe:

INGREDIENTS 

Four ripe banana's mashed
One apple puree (HIPP Organic)
Vanilla Extract
One cup of self raising flour
1 tsp Baking powder
3/4 of a coup of oats
1tsp cinnamon
One egg

METHOD 
Add the flour, egg, and, oats and puree into a bowl. Get an electric mixture and whizz up these ingredients. Next add the banana, vanilla, and cinnamon and whiz for a further two minutes. Bake in a pre-heated oven for 25/30 minutes. 

Icing:

1 1/2 tablespoons of meringue powder
1 teaspoon of vanilla extract
1 teaspoon of lemon juice
2 cups of powdered splenda
1/4 cup of warm water
Food colouring

Mix the powdered splenda and meringue powder. Add the vanilla, lemon juice and food colouring. Now add water and beat for 5 minutes (until stiff peak forms) In th ebowl of the mixer, whip together the sugar an meringue powder. The icing will be ready now.
