If you’re looking for a special treat to celebrate Valentine’s Day (or any day) these sugar cookie bars would be perfect!

They are a lot easier to make than regular sugar cookies since the dough is baked altogether in one baking pan, topped with frosting, then cut into bars.

I made these with half white sugar and half brown sugar because I am a brown sugar addict. I love the flavor and texture it gives to these bars compared to using all white sugar.

The vanilla frosting I made to go with these is my go-to frosting recipe. I like it on just about anything! But you could definitely use store-bought frosting if you’re in a pinch.

How to Make Sugar Cookie Bars – Step by Step

Step 1: Preheat Oven
 
Preheat oven to 350 degrees. Line a 9 x 13 inch baking dish with parchment paper or spray with nonstick cooking spray and set aside.
 
Step 2: Make batter
 
In a large bowl, beat together 1 stick of softened butter, brown sugar, and white granulated sugar with an electric mixer until light and fluffy. I let mine beat for about 3-5 minutes. Beat in the eggs and vanilla until smooth.
 
Step 3: Add dry ingredients
 
In a small bowl, sift together the flour, baking soda, baking powder, and salt. Gradually add dry ingredients to the batter a little at a time, beating over low speed.

Step 4: Bake
 
Evenly spread the batter into the prepared baking pan. Bake your sugar cookie bars in the preheated oven for 20 minutes, or until edges are golden brown. Remove from the oven and allow to cool completely before frosting.
 
Step 5: Make frosting
 
To prepare frosting: beat together 1 stick of softened butter and the powdered sugar until smooth. Add in the vanilla extract and milk and continue beating. Add in food coloring if desired.
 
Step 6: Decorate and serve
 
Spread frosting over the top of the cooled bars and top with sprinkles, if desired. Slice and enjoy!

Tips and Notes

  • Line your pan with parchment paper. It makes removal of your sugar cookie bars much easier, plus makes cleanup better, too. If you line it so that the paper overhangs the sides of your pan, you can use the flaps to lift the bars out of the pan, then place it on a cutting board to slice.
  • Use room temperature butter and eggs. Your ingredients will blend together more seamlessly with room temperature ingredients, and your dough will rise more easily as well. 
  • Customize your toppings. Feel free to change up the color of your frosting and the theme of your sprinkles. These bars can be made to match just about any holiday or event you might be celebrating!

How to Store Sugar Cookie Bars

Store any leftover bars in an airtight container on the counter for up to 5 days.

Can you freeze Sugar Cookie Bars?

To freeze your sugar cookie bars, I recommend placing them in the refrigerator for a few hours first to allow the frosting to stiffen up. That way you can stack bars together before freezing without worrying about the frosting getting smushed.

Just place the chilled bars in a freezer safe container or zipper freezer bag and freeze for up to 3 months. Thaw on the counter before enjoying.
