What are these cookie bars?

My version of gooey bar is a cookie (or cake) bar. Half the dough is pressed into the pan, then it’s filled with sweetened condensed milk and topped with the rest of the dough.

I’ve made these in SO MANY ways, with cake mix and from scratch, and all different flavors and fillings, but THIS one is my favorite.

Chocolate Chip Cookie Dough

The base of the cookie bars starts with a double recipe of my favorite chocolate chip cookie dough. That recipe is my old standby and it produces the best chocolate chip cookies ever.

Since my cookie dough is made with melted butter you can easily stir it together in one bowl with a spoon or spatula. Simply stir the butter and sugars, then add in the eggs, baking soda, salt and vanilla, and then the flour.

For chocolate chips you have choices:

Use regular chocolate chips (any kind)
Use mini chocolate chips
Use a combination of chocolate and peanut butter chips
Use chopped peanut butter cups

Trader Joe’s chocolate chips are my favorite – they stay melty and gooey even after the cookies cool.
PRO TIP

Peanut Butter Gooey Filling

My normal gooey bar filling is plain sweetened condensed milk, but for these bars I wanted a gooey peanut butter filling, so I mixed peanut butter with the SCM. This adds peanut butter flavor to every bite of these cookie bars.

I also filled the bars with miniature Reese’s Peanut Butter Cups. You can use any peanut butter cup size, just chop them if you use bigger ones than the minis.

How to layer gooey cookie bars

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, then add the peanut butter cups.

Drop pieces of the rest of the dough all over the top. It won’t be solid but it’ll bake together in the oven.

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.

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 minutes

Ingredients

▢ 1 cup unsalted butter, melted
▢ 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 chocolate chips
▢ 30 Miniature Peanut Butter Cups see note
▢ 1 14 ounce can fat-free sweetened condensed milk
▢ 1/4 cup creamy peanut butter

Instructions

Preheat oven to 350°F. Line a 9×13” baking pan with foil and spray with cooking spray for easy removal.
Stir together melted butter with both sugars. Add eggs, one at a time, mixing completely. Mix in vanilla extract, salt, and baking soda. Mix flour in slowly. Stir in chocolate chips.
Pour the sweetened condensed milk into a small bowl and add the peanut butter. Stir until smooth.
Press half the cookie dough in the prepared pan. (Spray your hands with nonstick cooking spray so it won’t stick to you.) Top the dough with peanut butter cups.
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.
