Peanut Butter Cup S’mores Blondies

16 Jan

Well, I’m not much for resolutions. In fact, the only resolution I’ve decided on thus far is to eat McDonald’s once a week. You might be surprised and disgusted to hear this, but I’ll explain my reasoning. First of all, I love McDonald’s. I’m unabashed about that. One time I went on a first date to McDonald’s and I was pumped. Secondly, I used to go to McDonald’s a TON a few years ago. I’d go a few times a week, usually to consume a hot fudge sundae with peanuts (only ONE DOLLAR, PEOPLE) or a cheeseburger and french fries (their french fries really are a league of their own) or a delicious breakfast sandy (“sandy” = cute word for sandwich). Looking back, I realized those were the good ol’ days.

I sincerely hope to get some impassioned responses to my one and only resolution. (Adrianne, you are disgusting or You are going to die a young death feeding your body that crap or Me tooooo, McDonald’s is AMAZE!!)

I realize many of you may feel McDonald’s is extremely unhealthy. So here’s a really healthy dessert option to balance out life. (Not! I FREAKING LOVE DELICIOUS FOOD.)

Peanut Butter Cup S'mores Blondies

I first had a variation of these PB cup s’mores bars over Thanksgiving, thanks to a sweet coworker. They are seriously addictive and the most pleasant combination of flavors in your mouth. When I started searching for a recipe to base these off of, though, the only recipes I found called for 16 PB cups. 16!! I only had 3 in my cupboard, so I made do with my own little recipe.

The result? Better than OK. Much better. Probably what makes these so great is the browned butter and brown sugar combo. The blondie base is truly delicious, and it makes the bars have a buttery, almost-caramel flavor. To recap: butter caramel flavor + peanut butter cups + marshmallow + milk chocolate + graham cracker = heaven.  Enjoy these addictive little treats.

Stir up your blondie dough.

Press 2/3 of the dough into pan and cover with peanut butter cups and milk chocolate chips.

Add your marshmallow layer, then top with remaining 1/3 blondie dough. (This will not be an exact science.)

Bake for 15 minutes, then top with graham cracker crumbles and continue baking another 5-7 minutes. Cool until set, then dig in!

Peanut Butter Cup S’mores Blondies

Makes 16 squares


1/2 cup unsalted butter
1 cup brown sugar, packed
1 egg, lightly beaten
1 teaspoon vanilla
1 cup flour
1 teaspoon baking powder
1/4 teaspoon salt
3-5 peanut butter cups, cut into large chunks
1/4 cup milk chocolate chips
7 oz. marshmallow creme
2 graham cracker sheets, crushed
1 tablespoon butter, melted


Preheat the oven to 350 degrees F. Spray an 8×8 square pan with cooking spray.

Cut the butter into chunks, and melt on  medium heat in a small saucepan. Once melted, turn the heat down to medium low, and cook for an additional few minutes until it begins to turn light brown and smell nutty. Remove butter from heat. Combine melted butter and brown sugar. Add the beaten egg and vanilla, and mix well.

In a separate bowl, stir together the flour, baking powder, and salt. Add the dry ingredients to the butter/sugar mixture all at once, and gently stir just until combined.

Press 2/3 of the dough into the bottom of the pan. Lightly press the peanut butter cups into the dough, evenly spacing them out. Sprinkle the chocolate chips on top of the dough, so it is mostly covered in chocolate pieces. Spread the marshmallow creme over the chocolate layer. Take pieces of the remaining dough and cover as much of the marshmallow layer as possible. The dough will not cover the marshmallow completely and may look a bit haphazard. No fear.

In a small bowl, combine the melted butter and crushed graham cracker crumbs. Set aside.

Bake for 15 minutes. Sprinkle the graham cracker crumbs on top of the blondies, and continue baking for an additional 5-7 minutes. The blondies will puff and brown but will sink considerably when cooled. Cool blondies for at least two hours to set before cutting and serving.

    I’ll totally agree that McDonald’s has super good ice cream, but seriously, I’d way rather have a peanut butter cup s’mores blondie.

      Agreed. If I may say so myself, these definitely beat McDonald’s sundaes!

    SO happy you have a new post. I’ve been sitting here in NOVA having to come up with recipes on my own. I’m happy for the return! 🙂

    Second, I went to McDonald’s Friday for the first time in over a year! Breakfast sandwiches are awesome. I picked a breakfast combo up before a 8 mile hike that morning. It hit the spot and was only $2.49! Fast food is great, when used responsibly. 😉

    Lastly, I’m excited for these special blondes! I’ve been making random goodies for the office on occasion and I look forward to making these (or a variation of – due to available ingredients – just like the recipe)!

    Hope all is well in the Southwest and am looking forward to your next great cooking adventure!

      Zach, the combination of McDonald’s + physical exercise is my personal favorite. The exercise makes me feel justified in having absolutely no guilt. Thanks for your devotion…more adventures to come!

    How you were able to get a picture of these is beyond me…I would’ve scarfed them down before they’d cooled. Time to add peanut butter cups to the grocery list!

      The answer: self-control. So, obviously, I didn’t wait. I cut myself a piece immediately and it was a gooey, delightful mess. Then using as much willpower as I could muster, I let them cool so I could document my success.

    McDonalds??? Adrianne, my opinion of you was just shattered 🙂 Just kidding – to each their own…I guess. Can’t wait to make these!
