Peanut Butter Cup Blondies

I tend to believe that the combination of chocolate and peanut butter is a good example of the whole being greater than the sum of its parts. I do love them on their own merits individually, but the two together is just something magical.

Peanut Butter Cup Blondies combine sweet, soft, chewy blondies with everyone's favorite - peanut butter cups!

I’ve lost count of the number of recipes I have collected over the years featuring this flavor pairing. My decision to make this particular recipe was based solely on the fact that I had recently, on a whim, bought a package of miniature peanut butter cups from Trader Joe’s. It was either bake with them or slowly eat them until the shame set in.

Peanut Butter Cup Blondies are a must for peanut butter and chocolate fans!

These blondies are a breeze to make. You can go from ingredients to oven in about 20 minutes. That’s always a plus for me. And the result is just as pleasing as you’d expect with this winning ingredient combination.

  1. These look amazing! Chocolate and peanut butter are the most reliable ingredient buddies.

  2. Trader Joe’s mini peanut butter cups……I also bought a container of those last week and have been trying to find a good recipe in which to incorporate them! I think this is it. Your photos make them appear delicious and so decadent and then on the top of your printed recipe it says the recipe is from “Cooking Light”. How can that be? These sound anything but light! And not that I don’t believe in trying to eat healthier and cut calories, but when I personally bake, I’m more like Paula Deen – the more butter the better! I like to bake FULL fat. Do these PB Blondies taste light?

    I also love the fact that they are so easy to throw together. That definitely is an incentive.

    Thanks for the recipe.

  3. Perfect! Thank you.

  4. Heidi, these didn’t taste light to me. You sound like my kind of baker!

  5. chocolate and peanut butter is an amazing combination. I will be making these for sure!

  6. Your site is so good (and tasty), it was the first site I saved into My Recipe Box on Allrecipes!

  7. The kiddo’s will love to make these….the hubs will love to eat these….

    My hips thank you!

  8. Just the thought of a peanut butter cup in each bite of a blondie makes me so hungry

  9. These look absolutely scrumptious. You are so right that chocolate and peanut butter together are better than the sum of its parts. Have you ever tried Trader Joe’s dark chocolate peanut butter cups? Those are my favorite. I don’t believe they come in mini, though, so you’d have to cut them up for baking. Anyway, thanks for the great recipe.

  10. I love those new mini Reeses cups, hadn’t thought yet beyond eating them plain…great idea here!

  11. i love the idea of baking my fave trader joe’s candies…

  12. These are cooling as we speak! They look fantastic! I am wondering how they cut though, I’m wanting to use a heart shaped cookie cutter instead of the typical square. Will they crumble? I don’t want to mess them up, since I’m taking them to a party! Love your blog, the photography makes me drool!

    • Hi, Jordan. These weren’t terribly crumbly, but I’m not sure they’d stand up to a cookie cutter. You might try refrigerating them for a bit before you cut them. That might make them firm enough. Good luck and enjoy!

  13. These look absolutely delectable! Peanut butter and chocolate is always a good combination. Can’t wait to try them out! Thanks!

  14. Yes Please!! I will be trying them out this weekend 😉 Always looking for new ways to bring peanut butter and chocolate together…this definitely is a welcome twist on peanut butter chips in regular brownies 🙂

  15. digging your whole blog! but i wonder, how do you give away these great recipes without feeling robbed? [since i’m married to a native italian & people are always asking for recipes…this is question for someone with experience.] thx for your consideration.

  16. I am so excited to try these. I have the dark chocolate PB cups from Trader Joe’s but not the minis. It will be worth the trip to go get them. Your photos are really stunning, and they sealed the deal for me.
