Thick, chewy, and overflowing with molten chocolate and peanut butter, Peanut Butter Chocolate Chip Cookie Bites (also known as peanut butter cup cookie cups) are the ultimate two-ingredient dessert. By baking pre-portioned refrigerated chocolate chip cookie dough inside a mini muffin tin and pressing a Reese’s peanut butter cup into the warm center the moment it emerges from the oven, you get deep-dish cookie cups with a warm, gooey peanut butter core.
Requiring zero mixing bowls, no measuring cups, and under 15 minutes of total time, this foolproof shortcut recipe is perfect for party platters, holiday dessert tables, bake sales, and quick weeknight sweet cravings.

Why This Recipe Works
- The Muffin Tin Mold: Baking cookie dough in the small cavities of a mini muffin tin forces the dough to puff upward into a deep, thick cup rather than spreading thin and flat on a baking sheet.
- Residual Heat Melting: Pressing the peanut butter cups into the freshly baked cookie dough immediately after removing the pan from the oven allows the residual heat to gently melt the chocolate shell and creamy peanut butter center without scorching.
- Perfect Proportions: Every bite delivers the ideal ratio of crisp, caramelized golden cookie edge, chewy chocolate-chip interior, and creamy peanut butter filling.
Equipment Checklist
- Standard 24-cup mini muffin tin (or two 12-cup mini muffin pans)
- Non-stick cooking spray with flour (or neutral baking spray)
- Wire cooling rack
- Butter knife or small offset spatula (to help release cups)
Detailed Ingredients
- 1 package (16 oz / 24-count) Refrigerated Chocolate Chip Cookie Dough: Pre-cut break-and-bake dough squares (such as Nestlé Toll House or Pillsbury). (Homemade chocolate chip cookie dough also works—portion into 1-tablespoon balls).
- 24 Reese’s Peanut Butter Cup Minis: Unwrapped miniature peanut butter cups (foil-wrapped minis or pouch-style unwrapped mini cups).
- (Optional Finishing Touch): A light pinch of flaky sea salt (such as Maldon) scattered over the tops.
Step-by-Step Instructions
1. Prep the Oven and Pan
Preheat your oven to 350°F (175°C) with a baking rack set in the middle position.
Generously grease all 24 cavities of a mini muffin tin with non-stick cooking spray, making sure to coat the bottom and sides well so the cookie cups release cleanly later.
2. Place the Dough
Separate the 24 squares of pre-portioned refrigerated chocolate chip cookie dough.
Place one dough square directly into each greased muffin cavity. There is no need to flatten or roll the dough into balls; the heat of the oven will melt and shape the dough evenly into the cup.
3. Bake to a Golden Puff
Transfer the muffin pan to the oven and bake at 350°F (175°C) for 10 to 12 minutes.
- Doneness Cue: The tops should be lightly puffed, and the edges should turn a light golden brown. Do not overbake, as the dough will continue to set as it cools in the hot pan.
4. Press in the Peanut Butter Cups
Remove the muffin tin from the oven and set it immediately onto a heatproof surface or wire rack.
Immediately press one unwrapped Reese’s peanut butter cup firmly into the center of each hot cookie cup until the top of the candy sits flush with or slightly recessed into the cookie rim.
(The hot, soft cookie center will crater around the candy, creating that signature deep-dish cup look).
5. Cool and Set
Let the cookie bites cool inside the muffin pan for at least 20 to 30 minutes.
- Baker’s Note: As the candy warms from the hot cookie, the chocolate will become shiny and molten. If you try to remove them while hot, the cups will collapse. Allowing them to cool lets the chocolate re-firm slightly while keeping the peanut butter center gooey and sliceable.
6. Release and Serve
Once the pan is cool to the touch, run the tip of a small butter knife or offset spatula gently around the outer edge of each cookie cup and pop them out of the tin.
Transfer to a serving platter and enjoy warm or at room temperature!
Pro Baker’s Tips for Success
- Unwrap Candies Before Baking: Have all 24 peanut butter cups unwrapped and ready in a bowl before the cookies come out of the oven. You must press them into the dough while it is still piping hot and soft.
- Faster Setting Trick: If you need the chocolate tops to set quickly for transport or packaging, place the entire muffin tin in the refrigerator for 15 minutes after pressing the candies in.
- Flaky Salt Finish: Sprinkle a tiny pinch of flaky Maldon sea salt directly onto the melted chocolate tops right after pressing them into the hot cookies to elevate the sweet-and-salty balance.
Delicious Flavor Variations
- Rolo Caramel Cups: Swap Reese’s for Rolo chocolate caramels for an oozing, gooey caramel center.
- Peanut Butter Dough Twist: Use refrigerated peanut butter cookie dough paired with chocolate kisses or mini dark chocolate cups for a double-peanut-butter indulgence.
- S’mores Cookie Bites: Use chocolate chip cookie dough, press a mini marshmallow and a square of Hershey’s milk chocolate into the center, and toast briefly.
Storage and Freezing Instructions
- Room Temperature: Store cooled cookie bites in an airtight container lined with wax paper at room temperature for up to 4 to 5 days.
- Refrigeration: Store in the fridge for up to 1 week for a firmer, fudge-like candy texture.
- Freezer Storage: Layer the cookie cups between parchment paper inside a freezer-safe container and freeze for up to 2 months. Thaw at room temperature for 15 minutes before serving.
