Ingredients and Their Roles
Cookie Dough Base
- Butter (melted): Creates a chewy texture and makes the dough easy to mix by hand.
- Granulated Sugar & Brown Sugar: Brown sugar adds moisture and chewiness, while granulated sugar helps with structure.
- Eggs: Provide stability and richness.
- Vanilla Extract: Enhances the overall flavor.
- Baking Soda & Salt: Ensures the bars rise properly and balances the sweetness.
- All-Purpose Flour: The main structure-building ingredient.
- Chocolate Chips: Adds melty chocolate pockets throughout the dough.
Gooey Peanut Butter Filling
- Sweetened Condensed Milk: Creates the signature gooey layer.
- Creamy Peanut Butter: Adds richness and deep peanut butter flavor.
- Miniature Peanut Butter Cups: Melty pockets of peanut butter and chocolate in every bite.
Ingredient Substitutions
- Butter: Substitute with coconut oil or margarine for a dairy-free option.
- Flour: Use a 1:1 gluten-free flour blend if needed.
- Chocolate Chips: Swap for white chocolate or peanut butter chips for variation.
- Peanut Butter Cups: Use chopped chocolate bars, caramel-filled chocolates, or nut butter cups for a twist.
Step-by-Step Instructions for Beginners
Step 1: Preheat your oven to 350°F and prepare a 9×13” baking pan by lining it with foil and spraying it with cooking spray. This makes cleanup easier and ensures the bars come out of the pan smoothly.
Step 2: In a large bowl, stir together the melted butter, granulated sugar, and brown sugar until well combined. Add the eggs one at a time, mixing thoroughly after each. Stir in vanilla extract, salt, and baking soda.
Step 3: Gradually add the flour, mixing just until no dry streaks remain. Be careful not to overmix, as this can make the bars dense. Fold in the chocolate chips.
Step 4: In a separate small bowl, mix the sweetened condensed milk with peanut butter until smooth. This will be your gooey filling.
Step 5: Press half of the cookie dough into the prepared pan. Spray your hands lightly with cooking spray to prevent sticking.
Step 6: Evenly distribute the peanut butter cups over the dough layer. Pour the peanut butter and condensed milk mixture on top, leaving a slight border around the edges.
Step 7: Break the remaining cookie dough into small pieces and scatter them over the filling. It won’t fully cover the surface, but that’s okay—the dough will spread as it bakes.
Step 8: Bake for 30-35 minutes, or until the top is golden brown and the edges are set. The center may still look slightly soft, but it will firm up as it cools.
Step 9: Let the bars cool completely before cutting. This allows the gooey filling to set and prevents a messy cut.
Beginner Tips and Notes
- How to Tell When It’s Done: The bars should be golden brown on top but still slightly soft in the center. A toothpick inserted near the edge should come out clean, while the center will firm up as it cools.
- Cooling is Key: Resist the urge to cut into the bars right away—cooling ensures a clean cut and prevents the filling from oozing out.
- Mess-Free Mixing: Since this dough is made with melted butter, you can mix everything with a simple spoon or spatula—no need for a mixer.
- Lining the Pan: Using foil or parchment paper helps lift the bars out easily, making cutting and serving effortless.
- Storing the Bars: Keep them in an airtight container at room temperature for up to 3 days, or freeze for up to a month.
Serving Suggestions
- With Ice Cream: Warm a bar slightly in the microwave and serve with a scoop of vanilla ice cream for an indulgent treat.
- Drizzle with Chocolate: Melt some extra chocolate and drizzle it over the top for added decadence.
- Crunchy Twist: Sprinkle crushed peanuts or pretzels over the gooey filling before baking for an extra crunch.

Description
Peanut Butter Cup Gooey Bars are rich, chewy cookie bars loaded with peanut butter cups and a creamy, gooey peanut butter filling. These decadent treats combine the best of chocolate chip cookies and peanut butter cups into one easy-to-make dessert that is perfect for any occasion.
Ingredients
- 1 cup unsalted butter, melted
- 3/4 cup granulated sugar
- 1 cup packed light brown sugar
- 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, chopped if using larger sizes
- 1 (14-ounce) can fat-free sweetened condensed milk
- 1/4 cup creamy peanut butter
Instructions
- Preheat the oven and prepare the pan: Preheat your oven to 350°F and line a 9×13-inch baking pan with foil. Spray it with cooking spray to ensure easy removal of the bars after baking.
- Mix the wet ingredients: In a large mixing bowl, stir together the melted butter, granulated sugar, and brown sugar until fully combined. Add the eggs one at a time, stirring well after each addition, then mix in the vanilla extract.
- Incorporate the dry ingredients: Add the baking soda and salt, stirring to distribute them evenly. Gradually mix in the flour, stirring until just combined to avoid overmixing. Gently fold in the chocolate chips.
- Prepare the peanut butter filling: In a small bowl, combine the sweetened condensed milk with the peanut butter and mix until smooth. This will create the gooey layer inside the bars.
- Assemble the layers: Press half of the cookie dough evenly into the bottom of the prepared pan. Scatter the peanut butter cups over the dough, ensuring even distribution. Pour the peanut butter and sweetened condensed milk mixture on top, leaving a small border around the edges.
- Add the top layer: Break the remaining cookie dough into chunks and distribute them over the filling. The pieces will spread during baking, creating a craggy, gooey top.
- Bake to perfection: Place the pan in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the edges are set. The center will still be slightly soft but will firm up as it cools.
- Cool completely before serving: Allow the bars to cool in the pan before slicing. This helps set the gooey filling and makes for cleaner cuts. For extra clean slices, chill the bars slightly before cutting.
Notes
- If you prefer a crunchier texture, add chopped peanuts or pretzels to the dough.
- To make slicing easier, use a sharp knife and wipe it clean between cuts.
- If you like an extra chocolatey taste, drizzle melted chocolate over the top before serving.
- For a gluten-free version, substitute the flour with a 1:1 gluten-free baking blend.
