What You’ll Need:

For the sugar cookie layer:

  • Butter – I prefer to use unsalted butter, softened to room temperature.
  • Sugar – A combo of brown sugar and granulated sugar.
  • Egg – Two eggs, at room temp.
  • Vanilla Extract – I prefer Watkin’s brand.
  • Flour – All-purpose flour works best in these bars.
  • Baking Soda – The leavener for these.
  • Cornstarch – To add extra softness.
  • Salt – Kosher salt is used.

For the simple buttercream frosting:

  • Butter – Again, unsalted butter at room temp.
  • Vanilla Extract
  • Half and Half – Or you can use whole milk.
  • Powdered Sugar – Two cups, or a bit more or less, depending on desired consistency.
  • Sprinkles – We like rainbow sprinkles!

How to make these frosted sugar cookie bars:

Step 1
Prep. Preheat your oven to 350 degrees. Add parchment paper to a 9×13 pan (linked below) so you can easily lift the bars out of the pan.

Step 2
Mix wet ingredients. In the bowl of a stand mixer with a paddle attachment (or use a large bowl and a hand mixer), cream the butter and both sugars together on medium speed until creamy. Add the eggs and vanilla, and mix again.

Step 3
Add dry ingredients. Add the dry ingredients (flour, baking soda, cornstarch, and salt) to the wet, and mix until just combined. Be careful to not over-mix.

Step 4
Press into pan. Then press the sugar cookie dough into the prepared baking pan, using your fingers to get an even layer.

Step 5
Bake. Bake the bars for 15-18 minutes, or until the top is just browned. You’ll want to slightly under-bake these bars so they are nice and soft.

Step 6
Cool. Remove the bars from the oven and let sit for about 10 minutes. Then carefully use the parchment paper to remove the sugar cookie bars to a cooling rack. Let cool completely.

Step 7
Make frosting. Add the butter to a separate bowl. Use a hand mixer to whip the butter for about a minute. Then add the vanilla, half and half, and powdered sugar. Mix again for another minute or so. Add a couple of drops of food coloring (optional) to the frosting and mix again.

Step 8
Spread frosting. Use a rubber spatula to evenly spread the frosting on top of the bars. Add sprinkles.

Step 9
Serve. Slice bars into 24 even squares, and serve.

I recommend pairing these sugar cookie bars with a large glass of milk or a cup of cold brew coffee.

Frequently Asked Questions:

  • Why turn sugar cookies into bars? Making sugar cookie bars is quicker and easier than making cookies. They require no chill time in the refrigerator and are quicker to make because you bake only one pan.
  • What is the difference between sugar cookies and shortbread cookies? The main difference between these two cookies is the ingredients and the ratios. Sugar cookies normally contain eggs, while shortbread cookies do not. Shortbread also has a higher ratio of butter to flour, resulting in a crumbly cookie.
  • Can I freeze these bars? You can freeze the sugar cookie bars BEFORE frosting them. Or you can freeze the dough and let thaw before pressing it into the pan to bake. Don’t freeze the frosting.
  • How long do leftovers last? Leftover sugar cookie bars stay fresh if stored in an airtight container on the counter for 3-4 days.

  2. Really tasty—these taste like the sugar cookies from a popular bakery where I live (Chicago) called Sweet Mandy B’s. I made them in a 9×9 inch pan and it worked well.
