For the Chai Masala Cupcakes.
I found two ways of going about this. Either a cream cheese icing, or a buttercream. I tried out the buttercream.
Ginger Spice Buttercream Icing
1/2 tsp. Ginger Powder
1/2 tsp. Garam Masala
10oz Icing sugar
Bit of hot water
1. Beat the butter till it's gone light yellow [or sunshine yellow, as I like to call it]
2. Mix the spices in with the sugar, and add that slowly to the mix butter.
3. Add the water slowly to the mix. It should go a nice smooth consistency.
For spreading onto the cakes, I put a dollop on, and spread it with the back of a bread knife [or a spatula].
Ginger Spice Cream Cheese Icing
I haven't tried this one [yet], but when I do, I shall post. You could effectively get a normal cream cheese icing recipe, and add the spices.
