Ingredients You’ll Need

This recipe calls for a handful of baking basics plus a generous helping of Butterfinger magic. Each ingredient brings something special to the party—texture, sweetness, or just that irresistibly nutty aroma that wafts from your oven.

  • Unsalted Butter: Softened to room temperature for a rich, tender cookie base.
  • Creamy Peanut Butter: The heart and soul of our cookies, giving that signature nutty flavor and creamy texture.
  • Granulated Sugar: For that sweet crispness that balances the peanut butter.
  • Brown Sugar: Packed into every bite for extra chewiness and a hint of caramel-like depth.
  • Large Egg: Helps bind everything together and adds richness.
  • Vanilla Extract: Just a teaspoon takes these cookies from good to unforgettable.
  • All-Purpose Flour: The classic cookie structure—just the right amount for soft, puffy cookies.
  • Baking Soda: Ensures that beautiful lift and those tender centers.
  • Salt: A pinch sharpens every flavor and keeps things from getting too sweet.
  • Chopped Butterfinger Bars: The surprise inside—crunchy, candy bar bursts in every single bite.
  • Extra Butterfinger Bits (optional): For topping your cookies and bringing a little visual flair.

How to Make Peanut Butter Butterfinger Cookies

Step 1: Prep Your Oven and Baking Sheet

Start by preheating your oven to 350°F. While that warms up, line a baking sheet with parchment paper—this makes cleanup a breeze and keeps your cookies from sticking. Trust me, this little step means flawless bottoms and easy, happy baking.

Step 2: Cream Together the Wet Ingredients

In a large bowl, cream together the softened butter, creamy peanut butter, granulated sugar, and brown sugar. Beat until the mixture is fluffy and pale (about 2–3 minutes), as this traps air for tender, light cookies. Now add the egg and vanilla extract, mixing until everything’s smoothly combined. You’ll already start smelling pure cookie bliss.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Mixing these before adding them in prevents any uneven patches of baking soda or salt—nobody wants a salty bite!

Step 4: Bring Everything Together

Gradually add the dry ingredients to the wet mixture, stirring just until you see no more streaks of flour. Over-mixing is the enemy of tender cookies, so go easy. Next, fold in all those glorious chopped Butterfinger pieces. Make sure they’re scattered throughout the dough so everyone gets their fair share of candy bar goodness.

Step 5: Scoop and Top Your Cookies

Scoop rounded tablespoons of dough onto your lined sheet, spacing them about 2 inches apart for even baking. If you’d like to amp up the wow-factor, press a few extra Butterfinger bits on top of each ball of dough before they go into the oven. This not only looks amazing but gives you extra crunch.

Step 6: Bake to Perfection

Bake the cookies for 9 to 11 minutes, just until the edges look lightly golden and the centers are set but still slightly soft. For that dreamy chewy texture, err on the side of underbaking—they’ll finish setting up as they cool. Let them rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. Try to resist eating them all warm from the oven (or don’t—the choice is yours)!

Garnishes

For a little flourish, sprinkle extra chopped Butterfinger bits over the cookies just after they come out of the oven. A light drizzle of melted chocolate or a pinch of flaky sea salt can really dial up the bakery vibes and gives your Peanut Butter Butterfinger Cookies some instant visual appeal.

Side Dishes

It doesn’t get more classic than serving these cookies with a big glass of cold milk—seriously, dunking is encouraged! For grown-up gatherings, try pairing with a scoop of vanilla ice cream or alongside a frothy cappuccino for indulgent cookie-and-coffee moments.

Creative Ways to Present

Stack your Peanut Butter Butterfinger Cookies and tie them with a pretty ribbon for gifting, or arrange them on a tiered dessert stand for special occasions. For parties, construct adorable cookie sandwiches with peanut butter or chocolate ganache as the filling. Watch them disappear in seconds!

Make Ahead and Storage

Storing Leftovers

Once the cookies have cooled, tuck them into an airtight container. They’ll stay soft, chewy, and packed with flavor for up to five days at room temperature (if you can resist them that long). A slice of sandwich bread in the container can help keep them extra moist, too.

Freezing

Great news—these are freezer champs! You can freeze baked cookies, well wrapped, for up to three months. Or freeze balls of cookie dough and bake off just a few at a time, straight from the freezer—just add a minute or two to the baking time. Fresh Peanut Butter Butterfinger Cookies on demand? Yes, please.

Reheating

If your cookies have lost a little softness, a quick 5-10 seconds in the microwave revives that freshly-baked magic. For frozen cookies, let them come to room temperature for best texture, or warm gently in a low oven for a few minutes.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add lovely little nutty bits for extra texture, making your Peanut Butter Butterfinger Cookies even more interesting. Just keep in mind that the dough may be a touch stiffer, so mixing by hand can help.

What’s the best way to chop Butterfinger bars?

For clean, even pieces, use a sharp chef’s knife and chop the Butterfinger bars while they’re cold—pop them in the fridge for 10 minutes first if it’s a hot day. This minimizes mess and captures more of those delightful shards and chunks!

Can I double the recipe?

Yes! This recipe doubles beautifully, so feel free to make a larger batch if you’re baking for a crowd or want to freeze extra dough. Spread the love—and the cookies—far and wide.

Are Peanut Butter Butterfinger Cookies gluten-free?

As written, this recipe uses all-purpose flour, so it’s not gluten-free. However, you can substitute your favorite cup-for-cup gluten-free flour blend to create an equally scrumptious gluten-free version. Just check your Butterfingers, as well, for allergen details!

Can I make these cookies ahead of time?

Definitely! The dough can be made a day in advance and chilled until ready to bake, which can actually enhance the flavors and hold the shape. Or bake them all, store properly, and enjoy stress-free treats all week long.

Final Thoughts

If you’re looking to shake up your cookie routine or simply want a dessert guaranteed to make you smile, give these Peanut Butter Butterfinger Cookies a try. They strike the perfect balance of familiar and fun, with enough nostalgic candy-bar energy to turn any day into a celebration. Grab some Butterfingers, invite some friends (or not), and enjoy every irresistible, joy-filled bite!
