How to Make Frosted Sugar Cookie Bars Recipe

  1. Cream Butter and Sugar: In a large bowl, beat 1 cup of softened unsalted butter and 1 ½ cups of granulated sugar with an electric mixer on medium-high for about 2 minutes. Make sure to scrape the sides down occasionally for even mixing.
  2. Mix in Eggs and Vanilla: Add 1 teaspoon of pure vanilla extract and 2 large eggs, continuing to beat until fully combined and fluffy.
  3. Combine Dry Ingredients: Gradually mix in the 2 ¾ cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of kosher salt until you see no more flour streaks—don’t overmix.
  4. Prepare the Baking Sheet: Line a 15x10x1 baking sheet with parchment paper. Using floured hands, drop the cookie dough onto the baking sheet and gently press it until evenly distributed. This may take a minute, but it’s worth the effort for even baking!
  5. Bake: Place the baking sheet in a preheated oven at 350 degrees Fahrenheit and bake for 15-18 minutes. Keep an eye on them! They’re done when the edges are slightly golden.
  6. Cool Completely: Once baked, remove the bars from the oven and allow them to cool completely on a wire rack.
  7. Make the Frosting: In a mixing bowl, beat together 1 cup of softened unsalted butter and 1 teaspoon of pure vanilla extract on high for about 2 minutes until fluffy.
  8. Add Powdered Sugar and Milk: Gradually add 3 cups of powdered sugar and 3 tablespoons of milk, beating for about 3-5 minutes until fully blended and fluffy. If you’re using food coloring, add it in at this stage and mix until combined.
  9. Frost and Decorate: Once the cookie bars are completely cool, spread the frosting evenly on top. Sprinkle with your favorite sprinkles for that finishing touch! Cut into squares, serve, and watch them disappear.

Storing & Reheating

To store your frosted sugar cookie bars, keep them in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them in a container for up to a week. If you want to extend their life even more, you can freeze them for up to three months by wrapping them tightly in plastic wrap, then foil. When you’re ready to enjoy them, simply thaw at room temperature. Note that while the texture may soften slightly upon freezing, a quick re-warm in the oven at 300 degrees for a few minutes can refresh their chewy goodness.

Chef’s Helpful Tips

  • Watch the Baking Time: Overbaking can lead to dry bars; keep a close eye on them in the last few minutes.
  • Ingredient Temperature: For best results, ensure your butter is softened but not melted. Room temperature eggs also help mix better into the batter.
  • Prevent Sticking: Lightly flour your hands when pressing the dough into the baking sheet to prevent it from sticking.
  • Customize the Flavor: Feel free to add other flavorings like almond extract for a different twist, or fold in some chocolate chips for added deliciousness.

Frosted sugar cookie bars are not only easy to whip up, but they also invite endless creativity. Whether you choose vibrant colors for a birthday party or go with classic white frosting for holiday gatherings, these bars embody the spirit of celebration. Make a batch today, and let your taste buds enjoy what is simply a classic treat!
