These bars can be customized for any holiday or occasion by simply changing the frosting color and sprinkles. If you are looking for other desserts great for parties then be sure to check out my Red Velvet Bundt Cake or Strawberry Shortcake Cookies!
Ingredients and Substitutions
The ingredients for these sugar cookie bars with frosting are pretty much the same as traditional cookies with the primary difference being the cooking method.
- Cookie Ingredients: Butter, sugar, all-purpose flour, vanilla extract, baking powder, and an egg.
- Frosting Ingredients: Powdered sugar, butter, vanilla extract, cream, and if desired - food coloring and sprinkles
Due the the precise nature of baking, I do not suggest making substitutions to these ingredients. See the recipe card for exact quantities.
Making frosted sugar cookie bars is seriously easy and takes no time at all. Before you start cooking, be sure to preheat your oven and grease and line a 9x13" baking pan with parchment.
Tip: The parchment paper is helpful for lifting the bars from the pan without breaking them. It only needs to stick out on two sides. I usually cut a strip that is 9 inches by about 14 inches. Greasing the pan keeps the parchment paper in place in the pan.
Tip: If you are like me and totally forgot to set your butter out to soften, don't worry! Just grate the butter into the mixing bowl and let it sit at room temperature for about 15-20 minutes and it should be good to go.
Start out by combining the butter and sugar. Beat them together with an electric mixer until they are light and fluffy. Then, add the egg, vanilla, and almond extract. Mix until combined.
Next add the baking powder, cornstarch, and half of the flour. Mix on low speed just until the flour is beginning to incorporate, then add the remaining flour. Mix until everything is combined and the dough is a similar texture to play-doh.
Spread the dough out into an even layer in the prepared pan using the back of a greased spatula.
Bake the cookie bars in the preheated oven for 15-18 minutes. Remove them as soon as the edges begin to brown. The dough may look slighly underdone in the center.
While the cookie bars cool prepare the frosting. Beat the butter, then add the vanilla, powdered sugar, and food coloring if you are using it. Mix until smooth then add the cream 1 tablespoon at a time until it reaches the desired consistency.
When the bars are compltely cooled, top them with the frosting.
Note: Don't be like me, use the parchment paper to lift the bars from the pan before you frost them 😉
Decorate the bars with sprinkles if desired and enjoy!
Since there is cream in the frosting I prefer to store these bars in the refridgerator. In a tightly sealed container they will keep for about a week. They can also be frozen for up to 6 months. Allow them to thaw at room temperature before eating.

Yes. Obviously homemade frosting is best, but you can use canned buttercream frosting to top these cookie bars.
- If you forgot to set your butter out to soften, don't worry! Just use a cheese grater to shred the butter into the mixing bowl and let it sit at room temperature for about 15 minutes and it should be good to go.
