So, funny story. Tomorrow I have to make cookies for a 40th birthday party. Inappropriate cookies, if you catch my drift.

Most of the desserts I’m making are totally G rated, but the other gals and I want to have a little fun at the birthday girls’ expense, which is how I found myself searching “<insert inappropriate food blog term here> cookie cutter” on Amazon.

(So far, the image hasn’t chased me around the internet, thank goodness.)

I’m making sugar cookies with different, um, shades of royal icing frosting. I am thinking, normally, the baking and frosting would take several hours, and I’d leave the cookies out to firm up (hahaha) at room temperature.

The problem is I have a 10-almost-11-year-old living in my house. So…if you need me I’ll be hiding in my garage, piping cookies.

Needless to say, I won’t be sharing those photos on this blog. Luckily, I’m sharing these instead.

Easy Peanut Butter Cup Gooey Bars - the BEST gooey bar recipe FULL of peanut butter flavor!

Y’all know how much I like my gooey bar recipes. I’m constantly dreaming up new versions because… Can’t stop won’t stop.

Today I married my Chocolate Chip Cookie Gooey Bars and my love of Reese’s Peanut Butter Cups.

Also, in case you were wondering, MEL ATE THESE. (<— That’s a sadly small amount of links, isn’t it? My husband is…interesting.)

Peanut Butter Cup Gooey Bars - this easy recipe is a keeper!! We couldn't stop eating these bars!

How To Make Peanut Butter Cup Gooey Bars

To make the Peanut Butter Cup Gooey Bars, you start by making my favorite chocolate chip cookie dough. That recipe is my old standby and it produces the best chocolate chip cookies ever. They’re made with brown butter and tons of brown and white sugar. Starting a cookie recipe with melted butter gives it amazing flavor.

I like to use mini chocolate chips in my cookie recipes because you get more bang for your buck – the chocolate gets more widely distributed all over the cookie. For these bars, I used part mini chocolate chips and part chopped Reese’s Peanut Butter Cups Miniatures.

That’s peanut butter #1.

Then the fun happens: the sweetened condensed milk. I mixed it with even more peanut butter.

And that would be peanut butter #2.

Peanut Butter Cup Gooey Bars are simple to assemble: just press half the dough in the bottom of the pan. It’s pretty easy to do this, since it’s a pretty liquidy dough right after mixing. The peanut butter sweetened condensed milk gets drizzled over the top, and the rest of the dough gets dropped all over the top.

When they bake up they become rich and gooey and so peanut buttery! Each bar is like a little meal that you can’t stop eating. Get out your glass of milk with these babies!

I can think of 100 reasons why you need to make the Peanut Butter Cup Gooey Bars recipe today. #1: because you just can’t NOT make them.

Enjoy!

The BEST EVER Peanut Butter Cup Gooey Bars - these chocolate chip cookie bars are filled with peanut butter cups and gooey peanut butter sweetened condensed milk!
Prep Time 22 minutes
Cook Time 46 minutes
Total Time 1 hour 10 minutes
Yield 24 -36 servings
Serving Size 1 bar

Ingredients

  • 1 cup unsalted butter
  • 3/4 cup granulated sugar
  • 1 cup light brown sugar packed
  • 2 large eggs
  • 1 tablespoon pure vanilla extract
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 1/4 cups all-purpose flour
  • 3/4 cup mini chocolate chips
  • 30 Miniature Peanut Butter Cups unwrapped (about 1 cup chopped)
  • 1 14 ounce can fat-free sweetened condensed milk
  • 1/4 creamy peanut butter

Instructions

  • Preheat oven to 350°F. Line a 9x13” baking pan with foil and spray with cooking spray for easy removal.
  • Melt butter in a saucepan over medium heat. Cook, stirring often, about 6 minutes, until it becomes brown in color. It will foam, reduce, then foam again. Once it’s done cooking the foam is a light brown and it will dissipate after you remove it from the heat. Once it starts to brown, keep stirring so it doesn’t burn. Let sit for about 5 minutes to cool.
  • Pour butter into an electric mixer fitted with paddle attachment. (You can also do this with a hand mixer.) While still hot, add both sugars and mix on low until combined. Let sit to cool for a few minutes. Add eggs, one at a time, mixing completely.  Mix in vanilla extract, salt, and baking soda. Mix flour in slowly. Stir in chocolate chips and peanut butter cups. Note: if you’re using a stand mixer, there is no need to chop the peanut butter cups because the mixer will do it for you. If you’re using a hand mixer, give them a rough chop before adding to the batter.
  • Pour the sweetened condensed milk into a small bowl and add the peanut butter. Stir until smooth.
  •  Note: if the dough is too soft to handle, you can chill it for 20 minutes before continuing.
  • Press half the cookie dough in the prepared pan. (Spray your hands with nonstick cooking spray so it won’t stick to you.) Pour sweetened condensed milk mixture over the top of the bottom layer (be careful to leave about 1/4” edge around the pan so the milk doesn’t touch the foil), then break up the remaining cookie dough and place on top of milk. Press with your hands to flatten. It will mostly cover but not completely cover the bottom layer.
  • Bake for about 30-35 minutes until the tops of the bars just start to get golden brown. Cool completely before slicing into bars.
  • Store in an airtight container for up to 3 days or freeze for up to one month. These are best served room temperature.

  1. You’re making THOSE cookies, huh? Well, if the blogging thing ever gets boring, you can have another career as an adult cookie maker. I’m sure it’s a huge industry somewhere!
    These are pretty much the only thing you could have done to the original gooey bars to make them better. Peanut butter cups are the best addition ever.

  2. It sounds like this was QUITE the 40th bday party! I hope your cookies were a huge success 🙂

    And these bars…gooey bar meets peanut butter cups. Amazing. And since Mel hardly eats any of your desserts, I don’t know what you do with them all! If my family didn’t eat 99% of what I made, I’d be in trouble. And I STILL have tons of people I donate stuff to!

  3. I’m almost 100% sure that if I searched for cookie cutters like that on Amazon that would be the only add I’d ever see anywhere online. How did you dodge that? ?
    All you really had to say was “goey bars” to get me interested in these. They look so thick and chewy. I’m hungry now.

  4. I could just lick the whole pan of these gooey bars. YUM! And those other cookies were pretty interesting too…hee hee hee
    xoxo

  5. I’m going to bookmark this recipe for a day when I’m really feeling upset. This is the perfect comfort food in my book. I can also see myself baking these up to eat around a bonfire in the summer with some cold ice cream. 😀
