Ingredients You’ll Need

These ingredients are simple but essential to create the luscious layers that make Reese’s Peanut Butter Cup Stuffed Brookie Bars truly spectacular. From rich chocolate chip cookie dough to fudgy brownie batter, each component plays a vital role in bringing amazing flavor and texture to every bite.

Chocolate chip cookie mix (17.5 oz): Provides the chewy, golden base that perfectly tugs at your taste buds.
Unsalted butter, 1 stick, softened: Adds richness and moisture to the cookie dough for that perfect tender crumb.
1 egg: Binds the cookie dough ingredients for stability without sacrificing softness.
30 miniature Reese’s Peanut Butter Cups, unwrapped: The star of the show that infuses every bar with gooey peanut butter and chocolate pockets.
Fudge brownie mix (18.3 oz): Creates the indulgent top layer with deep chocolate flavor and fudgy texture.
1/4 cup water: Moistens the brownie batter for a perfectly tender crumb.
2/3 cup oil: Keeps the brownie layer moist and luscious, ensuring it doesn’t dry out.
2 eggs: Essential for giving structure to the brownie topping while keeping it soft.

How to Make Reese’s Peanut Butter Cup Stuffed Brookie Bars

Step 1: Preheat and Prepare Your Pan

Start by preheating your oven to 350 degrees Fahrenheit and spraying a 9×13-inch baking pan with cooking spray. This ensures your brookie bars won’t stick and makes cleanup far easier. Having your pan ready ahead of time lets you move swiftly through the recipe steps.

Step 2: Make the Chocolate Chip Cookie Layer

In a mixing bowl, combine the chocolate chip cookie mix, softened butter, and one egg. Stir these together into a soft dough—not too sticky but definitely pliable. Press this dough evenly into the bottom of your prepared pan. This cozy cookie base will hold all the delicious ingredients while creating the perfect chewy texture.

Step 3: Add the Reese’s Peanut Butter Cups

Next comes the magic—place the 30 miniature Reese’s Peanut Butter Cups on top of the cookie dough layer. Arrange them gently in six rows of five cups each. This even distribution guarantees that each slice will have a decadent peanut butter chocolate surprise in every bite. Don’t press them down too hard; you want them nestled comfortably in the dough.

Step 4: Prepare the Fudge Brownie Top Layer

Using the same bowl, mix together the fudgy brownie mix with water, oil, and two eggs until smooth. The batter should be rich but pourable so it can evenly cover the peanut butter cups without overwhelming the cookie base underneath. Carefully pour this brownie batter over the cookie and candy layers, making sure the Reese’s are fully covered.

Step 5: Bake to Perfection

Bake your layers in the preheated oven for 40 to 45 minutes. You’ll know it’s done when the edges start pulling away from the pan and the top cracks slightly—a classic sign of a perfect brownie. Once baked, allow the brookie bars to cool completely. This cooling lets everything set beautifully, ensuring neat slices without crumbling.

Step 6: Slice and Serve

For clean cuts, use a sharp knife warmed under hot water and dried before slicing. Cut into 18 generous bars and watch those layers shine. Wrapped tightly, these bars stay fresh, moist, and ready to delight anytime.

How to Serve Reese’s Peanut Butter Cup Stuffed Brookie Bars

Garnishes

Sprinkle a light dusting of powdered sugar on top for a hint of sweetness that also adds a lovely visual contrast. For an extra touch, drizzle melted chocolate or caramel over each bar right before serving. A few crushed peanuts or a mini Reese’s cup on top can elevate the presentation and hint at what’s inside.

Side Dishes

Serve these brookie bars alongside a scoop of vanilla ice cream or a dollop of whipped cream to complement the rich chocolate and peanut butter layers. Fresh berries or a simple fruit salad can provide a refreshing balance to the indulgence, cutting through the sweetness with a bright, acidic note.

Creative Ways to Present

For parties, stack the bars on a decorative platter or tiered stand for an eye-catching dessert display. Wrap individual bars in parchment paper tied with twine for adorable party favors or gifts. You might also try warming a bar slightly and serving it hot with melting Reese’s peanut butter inside—pure bliss!

Make Ahead and Storage

Storing Leftovers

After the initial bake, store leftover Reese’s Peanut Butter Cup Stuffed Brookie Bars in an airtight container at room temperature for up to three days. Wrapping them individually in plastic wrap helps maintain freshness and prevents them from drying out.

Freezing

These bars freeze beautifully! To freeze, wrap each bar tightly in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 3 months without losing flavor or texture. When you’re ready to enjoy, thaw them overnight in the refrigerator.

Reheating

To bring back that fresh-baked warmth, microwave a brookie bar for about 15 seconds or warm it in the oven at 300 degrees Fahrenheit for 10 minutes. This reheating melts the peanut butter cups to a gooey perfection again and revives the soft texture.

FAQs

Can I use homemade dough and brownie batter instead of box mixes?

Absolutely! While box mixes make the process quick and foolproof, homemade versions of cookie dough and brownie batter can add a personal touch and allow you to customize flavors and ingredients. Just ensure your dough and batter have similar consistencies for best layering results.

Do I have to use miniature Reese’s Peanut Butter Cups?

Miniature cups work best for even distribution and easy slicing. However, if you only have regular-sized Reese’s, you can cut them in halves or quarters to fit snugly in the cookie layer. This maintains those gooey pockets in every bite.

How do I prevent the bars from being too dry?

Keeping both cookie dough and brownie mix moist is key. Don’t overbake; watch for the edges pulling away and the top cracking as your bake indicators. Also, proper storage in airtight containers preserves moisture after baking.

Can I make Reese’s Peanut Butter Cup Stuffed Brookie Bars ahead for a party?

Yes! These bars are perfect for making in advance. Bake them a day or two before your event, store properly, and slice right before serving. They hold well and taste even better once rested.

What’s the best way to cut the brookie bars neatly?

Use a sharp knife and run it under hot water before drying to create smooth cuts. Clean the knife between slices to avoid sticking and tearing, resulting in those perfect, picture-worthy bars.

Final Thoughts

Trust me, once you dive into these Reese’s Peanut Butter Cup Stuffed Brookie Bars, your dessert game will never be the same. They’re simple to make yet deliver an unforgettable explosion of flavor and texture. Whether you’re treating yourself on a cozy night in or sharing with friends, these bars are guaranteed to bring smiles and requests for seconds. Go ahead, bake a batch—you won’t regret it!

Ingredients

Scale

Bottom Layer

17.5 oz Chocolate Chip Cookie mix
1 stick unsalted butter, softened (113 g)
1 large egg

Middle Layer

30 miniature Reese’s Peanut Butter Cups, unwrapped

Top Layer

18.3 oz Fudge Brownie box mix
1/4 cup water (60 ml)
2/3 cup vegetable oil (160 ml)
2 large eggs

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and generously spray a 9×13 inch baking pan with cooking spray to ensure easy removal of your brookie bars.
Make the Cookie Dough: In a mixing bowl, combine the chocolate chip cookie mix, softened unsalted butter, and one egg. Stir together until you have a soft dough consistency. Press this dough evenly into the bottom of the prepared baking pan to form the base layer.
Add Peanut Butter Cups: Gently press the 30 miniature unwrapped Reese’s Peanut Butter Cups evenly into the cookie dough base. Arrange them in 6 rows of 5 cups each, making sure they are slightly embedded but still visible.
Prepare Brownie Batter: In the same bowl, combine the fudge brownie mix with 1/4 cup water, 2/3 cup vegetable oil, and 2 eggs. Mix everything thoroughly until smooth and well incorporated.
Pour Brownie Layer: Carefully pour the brownie batter over the cookie and peanut butter cup layers, covering all the candy evenly and spreading it out to the edges of the pan.
Bake: Place the pan in the preheated oven and bake for 40-45 minutes. The brookies are done when the edges begin to pull away slightly from the sides of the pan and the top has characteristic cracks.
Cool and Cut: Remove the pan from the oven and allow the brookie bars to cool completely in the pan. For clean cuts, use a sharp knife warmed under hot water and sliced dry. Cut into 18 bars and store wrapped tightly to keep fresh.

Notes

Use a sharp, hot knife to cut bars cleanly without crumbling.
Allow brookies to cool fully for best texture and easier slicing.
Store bars tightly wrapped at room temperature for up to 3 days or refrigerate for up to a week.
You can freeze individual bars wrapped well for up to 2 months; thaw before serving.
If you prefer a more fudgy brownie layer, reduce baking time slightly to avoid overbaking.
