While attempting a Pantry Challenge, I discovered a bag of Butterfinger bits from a recent ice cream party with the kids.
Inspired, I transformed these bits into the most divine cookies ever. Adapted from my Fluffernutter Peanut Butter Cookies, these cookies are a pure delight!
Soft, chewy, and bursting with flavor, they're irresistible. I confess, I devoured most of them within 24 hours, they're that good!
As a peanut butter cookie lover, these scratch-made treats are a special treat. While I typically enjoy my Cake Mix Peanut Butter Cookies or Cake Mix Peanut Butter Blossoms, these homemade PB cookies are a true delight.
If you still have Butterfinger bars left, try pairing them with my Butterfinger hot cocoa for the ultimate treat combo!

💛 Why You'll Love This Recipe
- They're great for leftover candy! Holidays like Easter or Halloween often mean an abundance of candy in the house.

- Easy to follow steps. The steps needed to make these cookies are very simple and easy, making them beginner-friendly! Great for a first-time baker.
🛒 Ingredients

Sugars- For soft and chewy cookies, you'll want to use both brown sugar and granulated sugar. (This is a pretty common trend with cookies, like in my Butterscotch Chocolate Chip Cookies).
Peanut Butter- I prefer to use creamy peanut butter but feel free to use chunky if that's what you'd like. I tested this recipe with basic peanut butter like Jif and Skippy, and I do not recommend high fat or fancier nut butter as the consistency and moisture content are not the same.
You can use any kind peanut butter in recipes like my Peanut Butter Banana Overnight Oats or Spicy Peanut Butter Ramen, but baking recipes have to be more precise for accurate results.
Butterfingers bar- For that delicious peanut butter chocolate flavor, you'll want to use Butterfinger candy bars. Use more for garnish if desired. Using Butterfinger bits works fine too.

💰 Budget-Friendly Tips
Buy candy bars in bulk. Grab Butterfinger bars from the value pack or the baking section instead of single bars, much cheaper per ounce.
Freeze extras. These cookies freeze beautifully, make a double batch while ingredients are cheap and save some for later.
Use up leftovers. Crumble leftover candy pieces over ice cream or yogurt instead of tossing them, nothing goes to waste!
Use up Halloween leftovers. Chop up any mini chocolate bars, Butterfingers, Reese's, Snickers, Milky Way, or even KitKats, and fold them into the dough. A mix of candies adds fun flavor and texture while preventing waste.

👩🏻🍳 Expert Tips
- Let the cookies cool before moving. The hardest part about making these cookies is having the patience to let them cool properly and then removing them from the baking sheet.
- More patience = better results. Due to the soft texture of these Butterfinger bits cookies, it's best to leave the cookies to cool completely on the baking sheets before transferring them to a wire cooling rack. Waiting 5-10 minutes may be fine, but longer is better.
- Pro tip for easy cookie transport. Using a greased spatula helps get under them with little to no tearing of the cookie.
❄️ Storage, Reheating & Make Ahead
Storage: Store baked cookies in an airtight container at room temperature for up to 5 days. They stay soft and chewy for days but are best enjoyed fresh.
Reheating: Warm cookies in the microwave for 8-10 seconds to bring back that fresh-from-the-oven texture and melt the candy bits slightly.
Make Ahead: Prepare the dough up to 3 days in advance and refrigerate in a covered container until ready to bake. You can also freeze scooped cookie dough balls or fully baked cookies for up to 3 months. For best results, flash-freeze on a baking sheet for 1-2 hours before transferring to a freezer-safe container.
🥗 Side Dishes or Pairing Ideas
These cookies pair perfectly with a cold glass of milk or a warm cup of hot cocoa. You can also turn them into easy ice cream sandwiches using vanilla or peanut butter ice cream.
For parties, serve them on a snack board with popcorn, pretzels, or salted nuts for a sweet-and-salty combo, or include them on a dessert table with brownies and blondies for a fun variety.

❓ Recipe FAQs
Yes, adding milk chocolate chips would make these cookies full of rich flavor and goodness. I recommend adding no more than 1 cup of chocolate chips as there's plenty of candy in the dough already as well. Save any remaining chocolate chips for recipes like Chocolate Chip Loaf Cake or Honey Chocolate Chip Cookies.
The crispy center part of a Butterfinger candy bar is layers of peanut butter, just another reason why this cookie dough pairs perfectly with this candy.
You don't need to chill this cookie dough recipe, but you can if you want to. Just scoop and bake (from chilled) when ready. Note that you may need an extra minute or two while baking, but cooking the dough while it's still fridge temp cold is fine.
