We love these sugar cookie bars. In all honesty, I had never tried a bar version of cookies before, but now that I have, these will easily be made more often. 

They are incredibly simple. I took my favorite soft sugar cookie recipe and pressed the dough into a pan. Bake, cool, and frost… The end result is a soft, fluffy, and delicious cookie that takes less than an hour to make! 

Bonus? You can decorate them for ANY holiday or event by swapping the sprinkles or coloring the frosting!

Frosted Sugar Cookie Bar Ingredients:

The ingredient list for this recipe is simple. To keep them soft and cake like, I combined oil and butter in the dough. Don’t skip this step! It’s worth it, I promise. 

  • Flour- All-purpose flour, or white flour, is used in these cookies. 
  • Baking Soda and Baking Powder- The leavening agents that help give the cookies rise and that fluffy texture. 
  • Salt- Salt is an amazing flavor enhancer, but remember a little goes a long way.
  • Butter- Soft butter at room temperature is best. 
  • Oil- I use vegetable or coconut oil for these cookie bars. 
  • Sugar- Regular white sugar, or granulated.
  • Powdered Sugar- Just a touch, added to the batter to help keep the cookies soft. 
  • Sour Cream- THIS is the secret. It adds a slight tang and is so incredibly vital to the end result. 
  • Egg- 1 large egg to help bind things together.
  • Vanilla/Lemon Extract- I highly recommend you add the lemon. It gives them such a fresh flavor, but you can always stick with just vanilla. 

Best Frosting Option for this Recipe:

Here is the deal with these cookies, pretty much any frosting will taste great. I like to stick with either vanilla buttercream or cream cheese frosting. Both are easy to make and easy to spread onto the top of the cooled bars. 

I also only like a thin layer of frosting. If you like more of a thick topping I would suggest doubling the frosting ingredients.

How to make soft and chewy sugar cookie bars:

  1. Preheat the oven to 375 degrees. Line a 9×13 pan with parchment or grease with cooking spray. Set aside.
  2. Whisk together the flour, baking soda, baking powder, and salt in a small bowl. Set aside. 
  3. Combine the butter, oil, and both sugars in a mixing bowl. Whisk or beat with the paddle attachment of an electric mixer until fully combined. Stir in the sour cream, egg, and extracts. 
  4. Fold in the dry ingredients until just combined. Transfer to your prepared pan. 
  5. Spray your hands with cooking spray and gently press the dough into the pan to create an even layer. 
  6. Bake 13 to 15 minutes, or until the edges are lightly browned and the center is set. Be careful not to over bake. 
  7. Allow the bars to cool completely. Spread with frosting and sprinkles. 

Vanilla Buttercream:

This is my favorite buttercream recipe. It tastes amazing on almost anything, especially this dessert!

Ingredients: Butter, powdered sugar, vanilla, milk or cream

  1. Gently whisk the butter with an electric or hand held mixer. Add the powdered sugar, vanilla, and milk/cream. 
  2. Whip until fluffy, about 3 minutes.

Tips to make perfect sugar cookie bars:

These bars are already so simple to make. I included some of my favorite tips to make them even easier!

  • Line your pan with parchment. This helps pull the bars out quickly without any sticking!
  • Pinch the parchment to the pan using binder clips while you spread the dough. This easy tip makes it so the parchment doesn’t slide or slip while you are spreading the sticky dough. Just remember to remove the clips before you bake.
  • Mist your hands with cooking spray to help keep the dough from sticking while you press them into the pan. You could also spray a large spoon, but we find that clean hands work best. 
  • Pull the bars from your pan right after you take them out of the oven to help them cool faster. 
  • Wait until the bars are completely chilled before you frost them, otherwise the frosting will melt.

Tools for this recipe:

  • A 9×13 pan with sharp, not curved, edges. Full disclosure. I used one with rounded edges when I made these and ended up trimming the ends off… My husband loved these so much that he actually suggested we order this pan. I just received it yesterday and can’t wait to use it!
  • Parchment paper is so handy for so many recipes, but especially cakes and cookies! It helps keep them from sticking to the pan, is amazing when baking cakes and helps them slide out smoothly, and so many more uses! 
  • This good grips spatula. It is the perfect size. We use it for EVERYTHING. 
  • Sprinkles! I used these adorable 4th of July sprinkles from Fancy Sprinkles. They have a good variety of shapes and sizes and have already been complimented by so many people!
