I used the Crabapple Bakery recipe for the first time ever last week, and it was sooooo yummy, and tasted just like the ones in their stores.

200g unsalted softened butter
1/2 cup milk
1 tbs vanilla extract
8 cups icing sugar

Butter and milk both at room temp. If using milk from fridge, microwave for bout a minute.

Cream butter for 1-2 mins. Add the milk, vanilla and half sifted icing sugar and beat for another 3 mins. Add remaining sugar and beat for a further 3 mins until light and fluffy, and of a spreadable consistency. Add some extra milk if too dry, or extra sugar if too wet.

I am far from a good baker, and this work perfectly for me the first time. Personally though I would halve the ingredients, as I had a heap left over which is now in my freezer waiting for another cake to ice

Good luck hun, and I'm sure whatever you do will be perfect x
