How to Make Frosted Sugar Cookie Bars

Follow these easy steps to make delicious sugar cookie bars.

Step 1 | Preheat oven to 350°F

Preheat your oven to 350°F.

Step 2 | Prepare the pan

Spray a 9×13-inch baking pan with baking spray and then line it with parchment paper. Set it aside.

Tip: we use baking spray to help keep the parchment in place. We also cut the corners of the parchment, which will help it fit better in the pan.

Step 3 | Cream the Butter and Sugar

In a mixing bowl, cream the softened butter and granulated sugar until well combined.

Step 11 | Cut and Serve

Once the frosting has set, cut the bars into squares, and they are ready to serve!

Tip: to cut even pieces, use a ruler (or measuring tape) to measure the width and length of the cooked bars. Divide the width in inches by 4 and the length by 6. Measure and mark your cut lines on all sides. Use a knife (we like to run under hot water to make clean frosting lines) and line up the cut marks side to side and slice through. Wiping off your knife each time.

More About This Recipe – Notes from Kelsey

These Halloween sugar cookie bars are a great choice when you’re looking to share some Halloween spirit at parties and potlucks or surprise your kids with a tasty treat in their lunchbox. We love the eye-catching orange frosting and Halloween-themed sprinkles.

Before you dive into baking these, here are some important notes to keep in mind about this delicious recipe:

  • The cookie layer is soft, chewy, and delicious.
  • If you love frosting, you can double up the frosting recipe for a super thick layer.
  • The recipe is made in a 9×13 baking pan, and we suggest cutting the bars into 24 pieces.

Tips for Making Sugar Cookie Bars

  • Soften butter: Make sure to soften the butter ahead of time for a smoother creaming process. If you forget to take the butter out beforehand, use the defrost setting to soften it using small increments to avoid melting it.
  • Even mixing: Mix the ingredients thoroughly to achieve a consistent cookie dough. Carefully measure the ingredients—especially the flour—so you don’t get a dry cookie layer.
  • Frosting & sprinkles fun: Get creative with the frosting by adding drops of orange food coloring (or purple, black, or whatever color you prefer). Sprinkle with your favorite sprinkles like jimmies and candy eyeballs.
