In the midst of yet another snowstorm hitting the area yesterday, I was struck by a case of the winter doldrums. I wanted to make something bright and cheery to lift my spirits. Frosted sugar cookie bars were the answer!
Soft, sweet and chewy, these bars are a luscious treat, sure to leave you smiling! The buttercream icing pairs perfectly with the rainbow sugar cookie. Be sure to use sprinkles in your cookie dough, instead of nonpareils. This will ensure you get a pretty funfetti effect.
Frosted Sugar Cookie Bars
- 1/2 cup unsalted butter, room temperature
- 3/4 cup granulated sugar
- 1 large egg + 1 egg yolk
- 2 teaspoons vanilla extract
- 1.5 cups all-purpose flour
- 1/4 teaspoon salt
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1.5 teaspoons cornstarch
- 1/2 cup rainbow sprinkles (not nonpareils)
- 3/4 cup unsalted butter, room temperature
- 2 1/4 cups confectioners’ sugar
- 3 tablespoons heavy cream or half-and-half
- 1 teaspoon vanilla extract
- salt, to taste
- food coloring
- extra sprinkles for decorating
- For the bars: Preheat oven to 350F degrees. Line an 8-inch or 9-inch square baking pan with aluminum foil, making sure to leave enough overhang on the sides. Set aside.
- In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, cream the softened butter for about 1 minute on medium speed. Get it nice and smooth, then add the sugar on medium speed until fluffy and light in color. Beat in egg, egg yolk, and vanilla. Scrape down the sides as needed.
- In a medium bowl, whisk together the flour, salt, baking powder, baking soda, and cornstarch. With the mixer running on low speed, slowly add the dry ingredients to the wet ingredients in 3 different parts. The dough is quite thick. Once combined, gently fold in 1/2 cup sprinkles using a rubber spatula (or by mixing on low speed).
- Press the cookie dough evenly into the prepared baking pan. Bake for 25-26 minutes or until very lightly browned on top. You want the cookie bars to be extra soft, so careful not to overbake. Allow the bars to cool completely on a wire rack at room temperature before frosting. The center will slightly sink – that’s normal.
- For the frosting: With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy – about 2 minutes. Add confectioners’ sugar, cream, and vanilla extract with the mixer running on low. Increase to high speed and beat for 3 full minutes. Add more powdered sugar if frosting is too thin or more cream if frosting is too thick. Add a pinch of salt if frosting is too sweet. Beat in food coloring.
- Remove cooled bars from the baking pan using the aluminum foil overhang on the sides. Frost the bars with a thick layer of frosting and decorate with extra sprinkles if desired. Cut into squares. Use a very sharp knife and wipe off with a paper towel between each cut to make neat, even cuts.
- Store bars in an airtight container at room temperature for up to 2 days and in the refrigerator up to 5.
