These Brownie Stuffed Peanut Butter Cookies have a secret worth biting into! A thick peanut butter cookie wraps around a fudgy dark chocolate brownie center, with milk chocolate chips tucked into the golden edges. Bake a batch of six giant cookies, let them rest just long enough to hold together, and break one open while the middle is still soft. They’re definitely the kind of brownie filled cookies that make any special occasion sweeter — or the perfect treat to bake just for yourself.

This peanut butter brownie cookies recipe is also part of my Chocolate Bliss Series — a collection of rich, indulgent chocolate treats for anyone who can never get enough chocolate in their life.

Why You’ll Love These Brownie Stuffed Peanut Butter Cookies

  • The first bite gives you soft peanut butter cookie, melty milk chocolate chips, and a proper fudgy brownie middle. Oh yes!
  • They are big, thick brownie filled cookies, with just six in the batch. One makes a generous dessert, especially while it is a little warm.
  • Leftover brownies are welcome here. Brownie bites or a freshly baked pan work, too, as long as the pieces can be shaped into centers.
  • You can finish them with more chocolate chips, a drizzle, or flaky salt. I like the salt when the brownies are especially rich.
  • Perfect for gifting for special friends, holidays and just because you’re a chocolate peanut butter fan and you just can’t resist! 🙂

Ingredients for Brownie Stuffed Peanut Butter Cookies

You’ll need six small brownie centers and one batch of peanut butter chocolate chip cookie dough. Choose moist, fudgy brownies because they hold together when pressed into discs. The cookie dough uses both granulated and brown sugar, so the outside bakes golden while the middle stays soft.

Brownie Centers for Stuffed Peanut Butter Cookies

  • About 3/4 cup fully baked, cooled fudgy brownies or brownie bites, enough to make six centers of about 2 tablespoons each

Each center should be roughly 2 inches across and 1/3 to 1/2 inch thick. A cutter makes tidy circles, but soft brownie pieces press together by hand, too. If you bake brownies just for this recipe, a shallow rectangular pan gives you thinner pieces that are easy to shape. Cool them fully before stuffing the cookies. Save the extra brownies for brownie pistachio truffles.

Peanut Butter Cookie Dough

  • 6 tablespoons unsalted butter, cool room temperature
  • 6 tablespoons granulated sugar
  • 1/2 cup packed brown sugar
  • 1/2 cup creamy or crunchy peanut butter
  • 1 large egg
  • 1 1/2 teaspoons vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup milk chocolate chips

I like creamy peanut butter for a smooth dough. Crunchy works if you want little peanut bits, although it takes more care to pinch the seams closed. Milk chocolate chips make the cookie sweeter against the dark brownie; semisweet chips give you a deeper chocolate bite.

How to Make Brownie Stuffed Peanut Butter Cookies

Shape the brownie centers, make the dough, then wrap and chill all six cookies. Keep the brownie discs smaller than the dough bases so you can seal the edges. This keeps the chocolate tucked inside!

Shape the Brownie Stuffed Cookies

  1. Press about 3/4 cup cooled fudgy brownies into six portions of about 2 tablespoons each. Shape each portion into a disc about 2 inches wide and 1/3 to 1/2 inch thick. If you prefer a smaller center, use 1 tablespoon per disc and save the remaining brownie.
  2. Beat 6 tablespoons butter, 6 tablespoons granulated sugar, and 1/2 cup brown sugar until light and fluffy. Mix in 1/2 cup peanut butter, 1 egg, and 1 1/2 teaspoons vanilla until smooth.
  3. Add 1 1/4 cups flour, 1/2 teaspoon baking soda, and 1/4 teaspoon salt. Mix just until the flour disappears, then fold in 1 cup milk chocolate chips. Divide the dough into 12 equal portions, about 1/4 cup each.
  4. Flatten one dough portion into a thick base about 2 1/2 to 3 inches wide. Set one 2-inch brownie disc in the middle. Flatten a second dough portion over it, then pinch and smooth the edges until the brownie is completely covered. Repeat with the remaining 10 dough portions and five brownie discs. This method gives you those irresistible brownie filled cookies with a soft peanut butter shell and a gooey chocolate center.

Bake the Stuffed Peanut Butter Cookies

  1. Arrange the six sealed cookies on parchment-lined baking sheets with room to spread. Refrigerate them for 20 minutes while the oven heats to 350°F. If the dough feels very soft, chill until the shaped cookies hold their height.
  2. Bake the six cookies at 350°F for 13 to 15 minutes, until the edges look set and the tops are puffed and matte. If your baking sheets do not fit comfortably side by side, bake one sheet at a time.
  3. Cool the six cookies on their baking sheets for 10 minutes before moving them. Press a few extra milk chocolate chips on top, add a chocolate drizzle, or finish with flaky sea salt if you like.

The centers will be soft when the cookies first come out, so give them those 10 minutes on the pan. Then split one open! For another stuffed brownie treat, these brownie mix cookie dough cups turn the layers around.

Tips for Thick Brownie Filled Cookies

Keep the brownie centers smaller than the cookie dough bases and seal every edge before baking. A bit of brownie showing through the seam can push the layers apart as the cookie spreads. I also leave the dough fairly tall rather than pressing it into a flat round.

  • For the best brownie filled cookies, make sure your brownie discs are firm enough to hold shape but still soft enough to stay fudgy after baking.
  • Use moist brownie pieces. If yours crumble instead of holding a disc, trim the dry edges and press the soft middles together. A teaspoon or two of melted chocolate can help dry crumbs bind.
  • Chill the assembled cookies for about 20 minutes, especially in a warm kitchen. Cold dough is easier to keep thick.
  • Watch the cookie edges and tops, not the brownie center, for doneness. The brownie is already baked; the surrounding cookie dough needs to set.
  • Let the cookies rest on the baking sheet before lifting them. These are generous cookies with heavy centers, and they firm up as they cool.

How to Store Brownie Stuffed Peanut Butter Cookies

Store fully cooled cookies in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Keep parchment between layers so the tops stay neat. For that just-baked softness, let a chilled cookie come to room temperature or warm it briefly before serving.

Freeze baked cookies, individually wrapped, for up to 2 months. Thaw them covered in the refrigerator. You can also freeze assembled unbaked cookies until firm, then pack them in a freezer bag. Bake from frozen at 350°F, checking after 15 minutes and adding a few minutes if the edges have not set. Since the batch makes six giant cookies, you can bake a few now and keep the rest frozen.

Variations for Brownie Stuffed Peanut Butter Cookies

Swap the milk chocolate chips for semisweet chips if you want a less sweet cookie around that fudgy middle. You can also use crunchy peanut butter for little nutty bits or sprinkle flaky salt on the warm tops. For a dessert plate, serve a cookie slightly warm with a scoop of vanilla ice cream. A chilled cookie is firmer and especially good cut into wedges for a dessert board.

Brownie bites make a handy shortcut when you don’t have leftovers. Keep each center near 2 inches wide. If you bake your own brownies, choose a fudgy batch; the soft pieces press together neatly. For another big-cookie mood, try these jumbo s’mores cookies next.

Brownie Stuffed Peanut Butter Cookies FAQs

Can I make brownie stuffed peanut butter cookies ahead?

Yes. Assemble the six cookies, cover them, and refrigerate for up to 24 hours before baking at 350°F. Let them sit on the counter while the oven heats if they feel very firm, then bake until the edges are set and the tops look matte.

Can I use store-bought brownies?

Yes. Use moist store-bought brownies or brownie bites and press them into six 2-inch discs. Very cakey pieces may crumble, so choose the fudgiest ones you can find.

Why did the brownie filling show through?

The brownie disc may have been too wide, or the dough seam may not have been fully closed. Keep each disc around 2 inches and each dough base closer to 2 1/2 to 3 inches, then smooth the dough over every edge.

Do I need to bake fresh brownies first?

No. Leftover brownies work beautifully once they have cooled completely. You only need enough to make six small discs, about 3/4 cup total.


treats ready for a dessert plate

Cut through one of these golden peanut butter cookies and that fudgy brownie center makes dessert feel like an occasion! Keep the middle thick, seal the dough all around it, and enjoy one slightly warm when the chocolate chips are soft.

Ingredients
  

Brownie Centers

  • ¾ cup fully baked, cooled fudgy brownies or brownie bites enough for six 2-tablespoon centers

Peanut Butter Cookie Dough

Optional Toppings

  • Extra milk chocolate chips, chocolate drizzle, or flaky sea salt to taste

Instructions
 

Shape the Brownie Centers

  • Press about 3/4 cup cooled fudgy brownies into six portions of about 2 tablespoons each. Shape each portion into a disc about 2 inches wide and 1/3 to 1/2 inch thick. Set aside.

Make the Peanut Butter Cookie Dough

  • Beat 6 tablespoons unsalted butter, 6 tablespoons granulated sugar, and 1/2 cup packed brown sugar until light and fluffy. Add 1/2 cup peanut butter, 1 large egg, and 1 1/2 teaspoons vanilla extract; mix until smooth.
  • Add 1 1/4 cups all-purpose flour, 1/2 teaspoon baking soda, and 1/4 teaspoon salt. Mix just until combined. Fold in 1 cup milk chocolate chips. Divide the dough into 12 equal portions, about 1/4 cup each.

Fill and Bake

  • Flatten one dough portion into a thick base about 2 1/2 to 3 inches wide. Place one 2-inch brownie disc in the center. Flatten a second dough portion over the brownie and pinch all edges shut. Repeat with the remaining 10 dough portions and five brownie discs to make six cookies.
  • Place all six cookies on parchment-lined baking sheets with room to spread. Refrigerate for 20 minutes while heating the oven to 350°F.
  • Bake the six cookies at 350°F for 13 to 15 minutes, until edges are set and tops are puffed and matte. Bake one sheet at a time if needed. Cool on the baking sheets for 10 minutes, then transfer to a wire rack. Finish with extra milk chocolate chips, chocolate drizzle, or flaky sea salt, if desired.

Notes

  • Use moist, fudgy brownies; cooled leftovers or brownie bites work. If dry pieces crumble, press together the softer centers with 1 to 2 teaspoons melted chocolate.
  • A shallow rectangular pan of brownies yields thinner pieces that are easy to shape, but you only need about 3/4 cup for these cookies.
