Ingredients You’ll Need

The beauty of Chewy Peanut Butter Butterfinger Cookies is how a handful of familiar ingredients come together to create pure cookie magic. Each addition has its moment to shine, from the richness of the peanut butter to the pop of Butterfinger crunch in every bite.

Unsalted Butter (1/2 cup, softened): Brings creamy richness and helps the cookies spread to that perfect chew.
Creamy Peanut Butter (1/2 cup): Provides the signature nutty flavor that’s at the heart of this cookie.
Light Brown Sugar (1 cup, packed): Adds moisture and a deep caramel note, ensuring every bite is deliciously chewy.
Large Egg (1): Binds everything together and adds tenderness.
Vanilla Extract (1 teaspoon): Enhances flavors and adds an inviting aroma.
Baking Soda (1/2 teaspoon): Gives the cookies a little lift for that soft center.
Salt (1/4 teaspoon): Balances the sweetness and draws out all the flavors.
All-Purpose Flour (1 cup): The backbone of the dough, keeping everything together with a tender crumb.
Chopped Butterfinger Candy Bars (1 cup): The secret ingredient for pockets of chocolatey, buttery crunch!

How to Make Chewy Peanut Butter Butterfinger Cookies

Step 1: Prep the Oven and Baking Sheet

Start by preheating your oven to 350°F and line a baking sheet with parchment paper. This not only prevents sticking, but also helps the cookies rise evenly and get those lovely crispy edges while staying chewy inside.

Step 2: Cream Butters and Sugar

Using a large mixing bowl, cream together the softened unsalted butter, creamy peanut butter, and light brown sugar until the mixture looks fluffy and pale. This step packs in air and ensures every Chewy Peanut Butter Butterfinger Cookie stays soft, not crumbly.

Step 3: Add Egg and Vanilla

Mix in the egg and vanilla extract. The egg holds everything together, while the vanilla gives a subtle, aromatic warmth that rounds out the peanut butter and Butterfinger flavors.

Step 4: Combine Dry Ingredients

Sprinkle in the baking soda and salt, giving the dough its needed lift and flavor balance. Then, gradually mix in the flour until you have a soft but cohesive dough — don’t overmix to keep those cookies tender!

Step 5: Fold in Butterfinger Pieces

Gently fold in the chopped Butterfinger candy bars, spreading that satisfying candy crunch throughout every cookie for ultimate Chewy Peanut Butter Butterfinger Cookies texture.

Step 6: Shape and Arrange the Cookies

Scoop up tablespoon-sized balls of dough and set them on your lined baking sheet, spacing them about 2 inches apart. This allows room for each cookie to spread and bake up perfectly round.

Step 7: Bake to Golden Perfection

Bake for 9 to 11 minutes, just until the edges are turning golden and the centers look barely set. For the chewiest results, slightly underbake — they’ll finish setting as they rest.

Step 8: Cool and Enjoy

Let your cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. This rest period ensures the cookies hold together and develop their chewy bite.

How to Serve Chewy Peanut Butter Butterfinger Cookies

Garnishes

For an extra flourish, sprinkle a little flaky sea salt on top right after baking. You could also drizzle melted chocolate or a light peanut butter glaze over the cooled cookies for a bakery-style finish.

Side Dishes

These cookies pair beautifully with a cold glass of milk, creamy hot chocolate, or even a scoop of vanilla ice cream. For a cozy gathering, serve them alongside mugs of coffee for a truly comforting treat.

Creative Ways to Present

If you’re gifting these Chewy Peanut Butter Butterfinger Cookies, stack them in a cellophane bag tied with a bright ribbon or arrange them in a rustic tin. For parties, build a cookie platter with extra Butterfinger chunks and chocolate squares for an eye-catching dessert spread.

Make Ahead and Storage

Storing Leftovers

Keep your cookies fresh and chewy by storing them in an airtight container at room temperature for up to five days. Slip a piece of bread in the container — it’ll help lock in moisture and keep the cookies soft.

Freezing

To freeze, arrange the cooled Chewy Peanut Butter Butterfinger Cookies in a single layer on a baking sheet and freeze until firm. Then transfer to a freezer-safe bag or container. They’ll keep for up to three months, ready for a sweet craving anytime.

Reheating

For that just-baked flavor, pop a cookie in the microwave for 10–15 seconds. If reheating a larger batch, warm them on a baking sheet in a 300°F oven for 3–5 minutes. They’ll taste (and smell!) freshly made.

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! Chunky peanut butter will add even more texture and little bits of nut throughout your Chewy Peanut Butter Butterfinger Cookies. Just be aware the cookies may have a slightly craggier look — but they’ll taste just as delicious.

How should I chop the Butterfinger bars?

For the best distribution, aim for rough, bite-size chunks rather than fine crumbs. This way, each cookie gets plenty of crispy, crunchy candy pieces in every bite.

Can I double this recipe for a crowd?

Go for it! This recipe scales up beautifully. Double all the ingredients and be sure to bake in batches or use multiple trays, as the cookies still need a little space to spread.

Do these cookies stay chewy after a day or two?

Yes — as long as they’re stored in an airtight container, your Chewy Peanut Butter Butterfinger Cookies will stay soft and chewy for several days. If they begin to harden, try the bread trick mentioned above to refresh their texture.

Can I use other candy bars in this recipe?

Definitely! Feel free to swap the Butterfinger bars for other favorites like Snickers, Milky Way, or Reese’s Cups. Just chop them into small pieces and fold them in as you would the Butterfinger for a personalized twist.
