Melt in Your Mouth Sugar Cookie Bars with Buttercream Frosting

I can’t be trusted with a working oven, a little sugar and butter. Especially if there’s anything to celebrate. You all loved my sugar cookie cake so much, I decided to make it in bar form. That’s right, melt-in-your-mouth frosted sugar cookie bars. Thick, indulgent and oh so good.

When you have a really great cookie dough recipe, it’s hard not to imagine it in other forms beyond a cookie. I love using mine to make cookie cobblers, cookie cakes, and cookie bars, because why not? Each has it’s own incredible texture and consistency. When you put my melt in your mouth sugar cookie dough into a 9×9 or 9×13 pan {depending on how ridiculously thick you want them}, they are so moist, chewy and delectable. Just one bite and you’ll see why Chris can’t stop at one. I’ve been known to munch on them for breakfast. That’s acceptable, right?

I’m excited to share my melt in your mouth sugar cookie bars with buttercream icing recipe today to benefit Cookies for Kids’ Cancer. Did you know that cancer is the #1 cause of death of children by disease in the U.S.? There are 40,000 U.S. children actively battling cancer right now. With less than 4% of the National Cancer Institute’s budget going to all childhood cancer combined, I wanted to get involved.

  10. Oh my gosh Julie!! This looks AMAZING…. I might just make these bars for tomorrow’s super bowl party. Why not spoil the guests!

  11. Just made these yesterday and they are delicious. We can’t stop eating them!!

    I used a 9×13 pan as suggested. For a thinner bar, I would suggest using a jelly roll pan and for thicker, use a 9×13. Based on my outcome, the dough would overflow a 9×9 pan and make a mess out of your oven.

  12. Wow! These sound so so good. I think I have all the ingredients too. I see our next dessert right here.

  13. I am a sucker for a good bar cookie, and have never thought to turn a sugar cookie into a bar. Genius idea! I am so happy that you have inspired me to think outside the box with this great recipe! Happy Valentine’s Day!

  17. I made these yesterday and took them to our bowling league – everybody raved about them and I got a couple of requests for the recipe. They are delicious!!

  18. I made these tonight and they are delicious! Do you store them in the refrigerator?

  19. If making in a 9×13 pan, how long would you bake Julie?

  20. These are adorable! Happy Valentine’s Day!
