I spent $80 at Target last week and it’s all my husband’s fault. I had a plan; a goal. I was JUST going to go to the cleaning section. I decided to try using a housekeeper again, to come in once or twice a month and just do deep cleaning and all the stuff I forget to do (like, you know, the blinds, fans and cleaning in general) so I had to buy some cleaning products.

(I know. In one single sentence I turned myself privileged with #firstworldproblems AND outed myself as a slob who actually was out of cleaning products.)

ANYWAY. I went into Target and went straight to the Swiffer aisle. I loaded up my cart and then looked at my list and my heart sank.

My husband needed tape. (You know, scotch tape? The tape that becomes invisible to adults and glows brightly for all children within 100 feet of it so it disappears before you need it?)

You guys, tape is all the way on the opposite side of the store from the cleaning products. To get there I had to walk through the ladies department, the children’s department AND the jewelry department.

My 10 minute trip to Target turned into 45 minutes and over $80. ALL BECAUSE MY HUSBAND NEEDED TAPE.

Target will be the death of me. At least I stayed out of the baking aisle; I would have spent another $40 on peanut butter chips and Buttefinger pieces if I’d gone there.

Triple Threat Peanut Butter Cookie Bars Recipe with peanut butter, peanut butter chips, Butterfingers, and chocolate!

Mel’s birthday was a couple weeks ago and to celebrate we went to the beach with a few families. The families all packed things like grapes and watermelon and bell pepper slices. The other kids are popping grape tomatoes and I was over on my beach chair asking if anyone wanted Snickerdoodle Bars or these Triple Threat Peanut Butter Cookie Bars.

Like I’ve said, I’m known as the sugar mom.

Anyway, I had to make something that Mel would eat and guess what? HE DID! He ate at least 3 of them. It was like, a record or something.

These cookie bars are the bomb. They start with a gooey peanut butter cookie bar (made with 100% brown sugar like my favorite blondies) which is based off of my favorite peanut butter cookie recipe. To take these to the next level I added a ton of peanut butter chips, chocolate chips, and chopped Butterfinger candy bars.

They’re the triple threat of peanut butter goodness.

  1. You were just lying to yourself if you thought you could clear Target without spending about $200. I never leave Target without spending that much. It’s a constant in my life. I never mean to…but there were some pretty maxi dresses there last week!
    These are AMAZING. I want to hang out at the beach with you and get some of these!

  2. Holy peanut butter – this looks fantastic! Target is evil. You can’t leave that store without spending $100! 🙂

  3. The Sugar Mom, yep I can relate. Grape tomatoes and watermelon are nice and all but I’m totally in your camp with passing out desserts 🙂 When I go out to dinner with people, go on hair appts, etc. I whip out a half of a pan of brownies, cake, etc from my purse and am like HERE. And I want these bars! Glad Mel loved them!

  4. These look amazing, Dorothy! I know what you mean about Target, it’s like they spray some kind of spending-inducing-drug into the air and I suddenly remember that I need EVERYTHING;-)

  5. Those butterfinger bits sound amazing in here- also Target is totally amazing and terrible at the same time, I feel ya!

  6. lol I love that you’re the sugar mom and I totallyyyy adore all the peanut buttery goodness in these bars!

  7. I guess that makes me the sugar grandmother!!? Sorry, I guess I started it when you were little and I had to have desserts around. However, you have surpassed my baking abilities and I wish there were some of these left for me. xoxo

  8. Humm, reading these I am drooling a bit and also wondering if I could top them with Reese’s peanut butter candies. Then, I could call it quadroople instead of triple. Will be trying for sure! 

  9. I love peanut butter so much. Therefore, I love these bars so much. Brilliant, D! 

  10. As always, these look beyond delicious! You are definitely my go-to for yummy baked goods. I use MasterCook to store all my recipes and I have a “” category!

  11. These bars look amazing! I often end up spending way more at stores than I intended too 🙂

  12. I love peanut butter so much. what a prety cake! it looks so amazing.

  13. I do not see cream listed on the ingredients.

  14. These bars are incredible.  My best friend loves peanut butter cookies, so I made a batch of these bars for her birthday. They were so good that I kind of hated to give them away!  I followed the directions, leaving out the chocolate chips. They came out perfectly!   Now I can’t wait to try some of the other recipes!
    Thank you!
