The best, easiest buttercream icing for frosting all the cookies and other sweet treats.
Cookies are lovely, but cookies decorated with a swirl of buttercream icing? Irresistible. I’m sharing my easy cookie icing recipe that will put the finishing touch on all of your favorite cookies.

Everyone needs a go-to cookie icing recipe and this one, my friends, is my most favorite. It has a beautiful texture and is a cross between a glaze and traditional buttercream frosting. It’s pipeable but soft and lightly flavored with vanilla.
My Favorite Kitchen Tools To Make This Recipe
From trusty pots and pans to handy gadgets, Iโve curated a list of products I use and love.
It’s the best icing for cookies and can be kept plain white, or you can tint it every color of the rainbow if you want something more colorful.
I love to use it to give my favorite M&M cookies a special touch, but it can be used to ice any cookies or treats that you like. It’s buttery like a buttercream frosting but with a softer, looser texture a few steps up in thickness from a glaze. We just love it.

Ingredients
- Confectioner’s sugar
- Softened butter
- Milk
- Clear vanilla extract
How to Make It
Cream the confectioner’s sugar and butter in a mixing bowl until smooth.

Gradually add the milk and vanilla with the mixer running until the icing is smooth and stiff. This will take about five minutes. If you would like to tint your icing add the color at this point.
Transfer the icing to a piping bag and frost your favorite cookies.
