My friend Jaime made some cookies recently that were so yummy, I just had to get the recipe. They are called Brown Butter Sugar cookies, and I seemed to remember seeing something about them on the web from one of my blogging friends. It sounded curious, and I was excited to make them myself!  I added a little twist, so today I bring you Peanut Butter Cup Brown Butter Bars.

Baking brown butter treats at home

The secret to these delicious treats are not just dark brown sugar, but browning the butter on the stovetop before adding it to the mixture. It nearly caramelizes the butter.  I like cookies, but BARS are really where it’s at for me. I don’t like edges, so the very center of the pan is my FAVE! I’m also a big texture lover, so throwing in some mini peanut butter cups as well as peanut butter CHIPS made this even more divine for me.

So soft.

      weird, your comment went to spam at first! I just approved it…I just love a good BAR, and like to think of what would mix well!

  2. Yuuuuum!

  3. I love everything about this!!

  4. I love your pretty food pictures. I feel like I can reach right out and grab this from my computer. Much fewer calories!

    • Kristen Duke says:

      You are just the sweetest, thank you!! It’s kinda tricky to make food look good, I’ve been working on it!!

  5. Yummy! Reese’s Peanut Butter cups are one of my favorite candies. These looks amazing!! Can’t wait to try them 🙂

    • Kristen Duke says:

      Thank you, Crystal! I kinda love Reese’s PB cups, too, and the mini’s are just so easy to pop in your mouth or pop in a favorite recipe!

  6. Ooooh so delicious!! I’m obsessed with brown butter and anything with pb cups!

  7. These look good, but I always want clear complete and accurate instructions before investing the ingredients in a new recipe. What are the two cookie sheets for in step 2? How big was the cake pan you used for the bars because they look thin, so it must have been a large pan. I’m sure that makes a difference in the bake time.

  8. These bars look amazing Kristen! Reese’s are my favorite 🙂 Pinned!

  9. Wow, those look amazing!

  10. What size of pan do you use? I really want to make these but it seems like a lot of dough for an 8×8 cake pan. Thanks a bunch for your help
