Ingredients for Sugar Cookie Bars

Cookie Bars:
1 cup (226 g) unsalted butter, softened
2 oz (57 g) cream cheese, softened
1 ¾ cups (350 g) granulated sugar
2 large eggs
1 large egg yolk
1 teaspoon vanilla extract
2 ¼ cups (285 g) all-purpose flour
½ teaspoon baking powder
1 teaspoon table salt
Frosting:
10 Tablespoons (141 g) unsalted butter, softened
2 oz (57 g) cream cheese, softened (see note for buttercream frosting option)
2 cups (250 g) powdered sugar
1 Tablespoon cornstarch (optional, for stability)
½ teaspoon vanilla extract
⅛ teaspoon table salt
Sprinkles for decoration (optional)

Step-by-Step Instructions

Preheat the oven: Set your oven to 350°F (175°C). Lightly grease a 13×9” (33x23cm) baking pan with baking spray or butter. Set aside.
Mix wet ingredients: In a large bowl, combine the softened butter, cream cheese, and granulated sugar. Use an electric mixer (or stand mixer) to beat until creamy and well-combined.
Add eggs and vanilla: Add the eggs, egg yolk, and vanilla extract to the butter mixture. Stir until completely combined.
Combine dry ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
Mix wet and dry ingredients: With the mixer on low speed, gradually add the flour mixture to the butter mixture until fully combined.
Bake: Spread the batter evenly into the prepared baking pan. Bake at 350°F (175°C) for 25-30 minutes, or until the center is set and the edges are lightly golden brown. Allow to cool completely before frosting.
Prepare the frosting: In a bowl, combine the softened butter and cream cheese. Beat with an electric mixer until smooth and creamy.
Add powdered sugar: With the mixer on low speed, gradually add the powdered sugar until fully combined. Stir in the cornstarch (if using).
Finish the frosting: Add the vanilla extract and salt. Stir until combined.
Frost and decorate: Spread the frosting evenly over the cooled cookie bars. Add sprinkles on top if desired. Slice and serve. Note: The frosting will crust slightly on top but will not solidify completely.

Frosting Variations and Topping Ideas

While the cream cheese frosting is a classic choice, you can switch it up with a buttercream frosting for a richer flavor. Simply skip the cream cheese in the frosting and use 1 cup (226g) of unsalted butter instead. For a fruity twist, add 2-3 tablespoons of your favorite jam or fruit puree to the frosting. Sprinkles are optional but fun—try using seasonal colors or themed sprinkles to match the occasion.

Perfectly Sliced and Served

For clean, even slices, use a sharp knife and wipe it clean between cuts. Serve these bars on a decorative platter with a side of fresh berries or a dollop of whipped cream for an extra treat. They’re perfect for parties, bake sales, or a sweet afternoon snack.

Storage Tips for Freshness

Store your Sugar Cookie Bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. If you’d like to freeze them, place unfrosted bars in a single layer on a baking sheet, freeze until solid, then transfer to a freezer-safe bag. Frost after thawing for the best texture.

Time-Saving Tricks for Busy Bakers

To save time, prepare the batter the night before and refrigerate it in the baking pan. Just let it come to room temperature before baking. You can also make the frosting ahead and store it in the fridge—just let it soften and give it a quick mix before spreading.

Equipment You’ll Love

A stand mixer or handheld electric mixer is a game-changer for achieving creamy butter and sugar mixtures. Don’t forget a good offset spatula for spreading the batter and frosting evenly. If you’re a perfectionist, a digital kitchen scale ensures precise measurements for consistent results.
