Sugar Cookie Bars – Soft and chewy sugar cookies in bar form! Topped with a sweet buttercream for a delicious and easy treat!

When it comes to dessert Frosted Sugar Cookies are one of the most requested desserts of all time in my house. They are a staple in December for Christmas cookies, but year round they are always welcome with my family.

But sometimes the idea of rolling out the dough, cutting into the shapes, and baking tray after tray is just a bit much. Which is where these sugar cookie bars make life so much easier!

  1. Cream butter and sugar together until the dough is light and fluffy. This will take about 2 minutes on medium speed with an electric mixer.
  2. Next add in the eggs, one at a time. You want to make sure each egg is fully incorporated before adding the next. Add in the vanilla with the final egg.
  3. In a separate bowl mix together the flour, salt, and baking soda.
  4. With the mixer on low, slowly add in the flour mixture, until just combined.
  5. Spread the dough into the prepared baking pan.
  6. Bake for 18-20 minutes, until a tester comes out clean.
  7. While the bars cool you can prepare the frosting by beating everything together until you get a nice spreadable consistency.

Baking Tips

  • You want to be careful not to over mix the dough. To get super soft and chewy sugar cookie bars, mix until all of the flour is just mixed into the dough.
  • Under Bake! Just like when you are baking regular cookies, the key to the best cookies is to slightly under bake them. They will continue to cook as they sit in the hot pan after you take them out of the oven. You can test them with a toothpick and remove as soon as it is mostly clean.
  • Sprinkles! You can really mix these up and make them for any holiday with seasonal sprinkles and coloring your frosting. And sprinkles make everything better, so if you wanted funfetti, you could even mix some into the dough!
  • Change up the flavor. You really can customize these however you want. You can use different extracts to flavor them almond, lemon or even Peppermint Sugar Cookie Bars.
  • You can easily double the recipe or even change the size of the pan. To get nice thick bars bake in a 13×9 inch baking dish as the recipe directs. If you want thinner bars you can bake in half sheet pan that is 13×18 inches (the baking time would shorten). Or you can double the recipe and put into a 13×18 inch baking dish and get these thick and chewy bars.

How To Make Ahead

There are a couple different ways you can make these ahead. If you want to completely bake everything, just store the baked bars and frosting separately until you are ready to serve. You can do this a day or two ahead of time, and then just frost when you are ready to serve.

You can also make the cookie dough, press it into the pan, and place in the fridge until you are ready to bake. The dough will last in the fridge for up to 2 days. Just remember you want the bars to cool completely before frosting.

These bars can be stored and room temperature, you just need to cover them first. They will last on the counter for 3-4 days.

If you want to keep them longer, you can store them in the fridge. We just like to take them out prior to serving so they aren’t chilled. They will last 5-6 days in the fridge.

You can also freeze these bars. Wrap tightly in plastic wrap and store in an air tight container for up to 3 months. Let them thaw on the counter before serving.

  1. Hello. I noticed this has 5 cups of flour. How thick are these cookies when baked in a 13″ X 9″ pan?

    Thank you so much for sharing the recipe. I love baking for my children and grandchildren.
