I love a good cookie bar recipe and these frosted sugar cookie bars are probably my fave! Just like my popular M&M cookie bars, I love that we can use all types of sprinkles to celebrate any occasion. Use red and green for Christmas, orange and purple for Halloween, rainbow colors for a birthday, pastels for a baby shower, the list goes on and on!
📋 Grocery List
This recipe is a basic sugar cookie dough pressed into a 9x13 baking pan, then topped with my favorite fluffy vanilla frosting. If you bake often, you probably have everything you need on hand.
Gather these ingredients:
- Unsalted butter (2 cups)
- Granulated sugar (1 cup)
- Egg (1 large)
- Vanilla extract (4 teaspoons)
- Flour (3 cups)
- Baking powder (2 teaspoons)
- Baking soda (1 teaspoon)
- Salt (½ teaspoon)
- Powdered sugar (3 cups)
- Milk (3 tablespoons)
- Sprinkles (optional, but recommended)
- food coloring (optional)
The food coloring is only needed if you plan to make either the dough or the frosting (or both!) another color. I highly recommend finishing the frosting off with colorful sprinkles, but it's not super necessary. You can also mix sprinkles into the cookie dough for a fun effect!

🍪 Cookie Bars for All Occasions
The best thing about these sugar cookie bars (besides their awesome taste and amazing fluffy frosting) is you can make so many different variations and serve them for any celebration. Both kids and adults love these so they seriously are perfect for every party!
For fancier cookies, try almond extract in the cookie dough instead of vanilla, or a little of both. Topped with delicate sprinkles like these or these, they would be beautiful for a wedding shower. Or how about these sprinkles for a baby shower or gender reveal party?
Imagine any birthday party theme, just color the frosting a matching color and find the right sprinkles! During Christmas, use peppermint extract and red coloring in the frosting topped with crushed candy canes! OH, I think I'll have to make that soon!

Do you have to use unsalted butter?
Nikki Gladd says
For the cookie dough, if you use salted butter, cut the salt listed in the recipe to 1/4 teaspoon. You can most definitely use the salted butter for the frosting.
