If you're a fan of the classic flavor combination of chocolate and peanut butter, you'll love these peanut butter cup blondies.

How to Make It

Step 1

Preheat oven to 350°.

Step 2

Weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 3 ingredients (through salt), stirring well with a whisk. Combine peanut butter and next 4 ingredients (through eggs), stirring well. Add peanut butter mixture to flour mixture; stir until combined. Stir in chocolate chips.

Step 3

Scrape the batter into a 9-inch square metal baking pan lightly coated with cooking spray, and arrange the peanut butter cups over batter. Bake at 350° for 19 minutes or until a wooden pick inserted in center comes out with moist crumbs clinging. Cool in pan on a wire rack.

Super easy and delicious.  I only have an 8 inch pan so my cooking time was longer by 15 minutes.  Impossibly small portion size.  Oh well.  Will definitely make again.

These are fabulous! I would give them more than five stars if I could! I topped mine with mini peanut butter cups instead of chopping large ones.

Amazing Blondies! Easy to make and super tasty - all you need is one bite to be convinced! They cut really nicely from the pan, and I got about 25 bars total (5 x 5). The total bake time was closer to 30-35 minutes before my bars were done fully (I used an 8 x 8 glass pan) and like another reviewer, I used the mini unwrapped peanut butter cups and just nestled them in rows across the top of the batter. I absolutely think these are a keeper and wouldn't hesitate to make again. The peanut butter flavor is very subtle so they definitely taste like blondies with the bonus of chocolate chips - enjoy!

I made these tonight with a few changes. Used light brown sugar instead of regular since that is what blondies typically have. Also used 1% milk (on hand), and baked in an 8x8 metal pan for about 25 minutes. Perfect!!! They are delicious and smelled so good while baking.

These really are outstanding! I used a glass dish and had to bake about 5 minutes extra. Super delicious. Great with a scoop of vanilla ice cream.

I was not as excited about these as the other reviewers have been. They were good but not as decadent as I was expecting. To me at least, they seemed like a light recipe - I realize that's exactly what it is, but I just hoped it wouldn't taste that way!

Really delicious! I used an 8x8 inch metal pan and it took a lot longer than 19 minutes. I never got crumbs when I put the toothpick in but the top was turning golden brown and it felt done when I touched it. I felt if I cut it inot twentypices they would be too small so I cut them into 16 pieces which comes to 191 calories each. My family loved them and I will definately make them again.

I made these for an event and got raving reviews! They are DELICIOUS! I didn't change a thing! We have a new baby at home and although I love to bake its something that has fallen by the wayside....however, these were SUPER easy and quick to make! I will definitely make them again and again!
