Peanut Butter Cup Blondies

Hmmm…another band rehearsal. I needed to figure out what fantastically yummy snack I would have ready to energize them as they worked through their set list. I decided that I was in the mood to bake brownies or some sort of bar type dessert. I may have mentioned that I love Reese’s Peanut Butter Cups and I just happened to have a bag of the new Reese’s Cup Minis sitting right on the counter. (Don’t know how they got there….) And then I remembered that Karly from Buns in My Oven (one of my all time favourite blogs) had blogged about this exact treat some time back. Everything I have ever made from Karly’s site has been off-the-hook delicious! I quickly checked her site. Just as I thought, it looked awesome…a peanut butter base filled with chocolate chips, chopped up Reese’s cups and as if that wasn’t enough, there’s a whole Reese’s mini squished into the top!

That’s what I’m talking about folks! I mean, sure, I was making these treats for the band but I would likely need to taste test one or two or maybe five or so, just to make sure they were acceptable. I wouldn’t want to serve anything not up to snuff. Yup, these Peanut Butter Cup Blondies were the ticket! So I got busy baking. The only thing I changed in her recipe was that I baked these lovely little treats in a mini muffin pan whereas she baked them in a 9×13 pan. I did change the name a bit too, she called them Peanut Butter Brownies and I christened these gems “blondies”.

The results? AWESOME! Moist, peanut buttery, chocolatey bliss! Not only did the band scarf them down, but I’d wager Santa would be delighted to find a few of these waiting for him when he comes down the chimney. Make some today!

Peanut Butter Cup Blondies

recipe slightly adapted from Buns in My Oven (Karly baked them in a 9×13 pan and I made mini muffin sized treats)

yield: 34 mini muffin sized blondies


  • 1 1/3 cups packed brown sugar
  • 1/4 cup butter, melted
  • 1/2 cup creamy peanut butter
  • 1 tsp vanilla
  • 3 eggs
  • 1 1/2 cups all-purpose flour
  • 3/4 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp salt
  • 36 mini peanut butter cups (Reese’s are the best!)
  • 1/2 cup milk chocolate chips


Pre-heat oven to 350 degrees. Line mini-muffin pan with mini cupcake papers.

In the bowl of a stand mixer, beat together sugar, peanut butter, butter, vanilla, and eggs until well blended. Mix in flour, baking powder, baking soda, and salt.

Cut 12 peanut butter cups into quarters and gently stir into blondie batter along with the chocolate chips. Use small cookie dough scoop to fill each muffin well. Place in oven for 12-15 minutes, or until a tester comes out clean.

Remove from oven and immediately press remaining peanut butter cups into the top of each blondie. Allow to cool before serving.
