Remove from the heat and add the vanilla. Beat until able to spread.
Note:
You can add colouring to the frosting if desired, and can also use almond, rum or lemon extract instead of the vanilla for flavouring.
Used different ingredients.
I use this recipe, but I add 4 marshmallows when I pull it off the heat, and beat until they melt and it's ready to spread. I've also used orange juice in place of water and orange extract in place of vanilla. It's great with my orange cream cake. It's a wonderful marshmallow frosting!
I love this icing! I've used it for years, and it never fails to be a favourite among kids and adults, as well as a wonderful decoration on any cake or cupcake.
