Ingredients & Substitutions

Bars: It starts with the sugar cookie dough for this recipe. Then, it’s all about the homemade buttercream frosting.

Butter: Unsalted butter is used in both the bars and the frosting. (If using salted butter, you may want to lessen or omit the salt in the recipe.) To properly cream the butter and sugar to form the buttercream, the butter must start at room temperature. If the butter is too cold, the emulsion might break causing a separated buttercream.

Eggs: For the bars, you will need 4 eggs (2 whole eggs and 2 egg yolks). The combination of egg yolks and whole eggs in the recipe helps create a tender and chewy texture in the sugar cookie bars, making them soft and delicious. And, don’t get rid of the egg whites! Save them to use in another recipe like Fried Ice Cream!

Frosting: American buttercream is the easiest style of buttercream to make with very few ingredients and steps. You will be able to pile on the frosting and make it as bright in color as you desire!

Food Coloring: Gel food coloring will give you a more vibrant color. If you are using liquid food coloring (not gel), you may need to add a little peppermint extract to offset the bitterness. Play around with colors to fit your celebrations or festivities! If the buttercream will not be used right away it must be stored in the refrigerator.

How to Make Bright Red Frosting

If it’s at all possible to plan ahead, make your icing a day or two in advance. The color will deepen considerably as it sets. The ratio I use is a 1-ounce bottle of McCormick red food color in about 4 cups of buttercream. If using gel, it will be much less. 

I make the frosting as directed and add the food color when I add the vanilla. Make sure it is fully incorporated, scraping the sides of the bowl as needed. Then, dampen a towel and set it over the bowl for a few hours. If the red looks perfect after a few hours, place it in an airtight container and store it until needed. If the color doesn’t seem red enough, add more food color 1/2 teaspoon at a time allowing it to set for a few hours between each addition. Letting the frosting rest overnight will darken it considerably and you often do not need any more food color!

Can I Make The Dough Ahead Of Time?

Sure! Just like you can make the frosting in advance, you can also get the dough for the bars made ahead of time. Once you have the dough made, wrap it in plastic wrap and store it in the refrigerator. It will last up to 2-3 days. If you want to store the dough for a longer period, you can freeze it. Double-wrap the dough in plastic wrap and place it in an airtight container or a freezer-safe bag. Frozen cookie dough can usually be stored for several months. When you’re ready to use it, allow it to thaw in the refrigerator before proceeding with baking.

  1. I am not sure if I did something wrong. These bars have been in the oven 30 minutes and still look like soft batter right on top. I don’t wanna over bake them, but I do want them baked.

  2. these are PERFECT. I made for a party and everyone asked for the recipe.
    I added a little almond extract to the buttercream and a sprinkle of flaked sea salt on top.
