Why I Love This Recipe

This is my mom's go-to frosting for EVERYTHING - cupcakes, cinnamon rolls, cookies, cakes you name it! The reason I call it the rule of 3 frosting is because everything is in multiples of three - three cups of sugar, three half-cups of milk, three tablespoons of butter, three half-teaspoons of vanilla. It is easy enough for the kids to make, can change consistency based on how much milk is added (less for frosting cookies, more for cinnamon roll glaze), and takes to food colouring very well. One batch is usually enough to divide into separate bowls, mix in different colours, and decorate a double-batch of sugar cookies. I will always remember sitting around the dining room table with my cousins decorating holiday cookies with rainbow bowls of homemade frosting.

Ingredients You'll Need

3 c powdered sugar
3 T milk
3 T butter, softened
1 1/2 t vanilla
food colouring (optional)


Mix everything together in a medium bowl. Seriously, that's it.

If the butter gets clumpy when combined with the cold milk, pop it in the microwave until it softens again.

Stir until smooth in consistency.

If using as a glaze, add milk until thin enough to pour.

If using as a cake or cupcake frosting, and it seems too thin, let set in the open until the surface hardens. When you stir the mixture together again, it will thicken.

If using as cookie frosting, divide into separate bowls and colour individually.

This also works great for decorating gingerbread men. Dump it into a sandwich bag, cut a small bit off of a bottom corner, and voila! Instant piping bag! Also a great activity for families since you can give each kid their own decorating bag.
