Ingredients Breakdown
Let’s take a closer look at what makes these cookies so delicious:
- Creamy peanut butter: The base of the dough, adding richness, flavor, and soft texture. Choose a regular creamy brand (not natural peanut butter) for best results.
- Unsalted butter: Adds moisture and helps achieve a chewy center with crisp edges.
- Granulated sugar: Contributes to sweetness and a slight crisp texture.
- Brown sugar: Adds depth of flavor and chewiness thanks to its molasses content.
- Egg: Binds ingredients and adds structure to the dough.
- Milk: Keeps the dough soft and prevents dryness.
- Vanilla extract: Enhances all the other flavors in the cookie.
- All-purpose flour: The foundation that provides structure.
- Baking soda: Gives the cookies a gentle rise and soft texture.
- Salt: Balances sweetness and enhances flavor.
- Chopped Butterfinger candy bars: The star ingredient that adds crunch, chocolate, and a caramel-like sweetness throughout.

Tips and Tricks for Perfect Cookies
- Don’t overbake: Cookies should look slightly underdone in the center—they’ll firm up as they cool.
- Use room temperature ingredients: Soft butter and room-temp egg help the dough blend smoothly.
- Chop Butterfingers finely: This ensures even distribution and prevents large chunks from burning.
- Avoid natural peanut butter: It can make the dough oily and less stable.
- Line baking sheets with parchment: Prevents sticking and helps cookies bake evenly.
- Space cookies properly: They spread a little while baking, so leave about 2 inches between each scoop.
Variations and Customizations
These chewy cookies are easily adaptable—try one of these fun variations:
- Chocolate Drizzle: Melt chocolate chips and drizzle over cooled cookies for an extra-rich finish.
- Add Reese’s Pieces or M&M’s: Mix them in for a colorful, candy-packed version.
- Stuffed Cookies: Wrap the dough around a mini peanut butter cup for a surprise inside.
- Oatmeal Version: Add ½ cup quick oats for extra texture and a heartier feel.
- Double Butterfinger: Stir in half the candy pieces before baking and press more on top as soon as they come out of the oven.
Pairing Suggestions
Enjoy these chewy peanut butter cookies with your favorite treats or drinks:
- A glass of cold milk: The classic pairing for rich peanut butter cookies.
- Hot coffee or cappuccino: Balances the sweetness beautifully.
- Vanilla ice cream: Sandwich two cookies with a scoop of ice cream for the ultimate dessert.
- Hot cocoa: Perfect for cozy nights and holiday gatherings.
Storage Instructions
Keep your cookies fresh and chewy for days with these simple storage tips:
- Room Temperature: Store in an airtight container for up to 5 days.
- Refrigerator: Store for up to 7 days; bring to room temperature before serving.
- Freezer: Freeze baked cookies for up to 2 months in a sealed container. To reheat, warm in the microwave for 10–15 seconds for that just-baked feel.
- Freezing dough: Scoop portions onto a baking sheet, freeze, and store in freezer bags. Bake directly from frozen, adding 1–2 extra minutes.
Popular Questions
Can I use chunky peanut butter instead of creamy?
Yes, but it will change the texture slightly, making the cookies a bit crumblier and nuttier.
Can I make these gluten-free?
Absolutely. Use a high-quality gluten-free all-purpose flour blend at a 1:1 ratio.
Why are my cookies spreading too much?
Your butter may have been too soft. Chill the dough for 10 minutes before baking to prevent excessive spreading.
Can I use Butterfinger baking bits instead of candy bars?
Yes, Butterfinger bits work perfectly and save chopping time while giving the same flavor and crunch.

Chewy Peanut Butter Butterfinger Cookies
Ingredients
Method
- Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper. Chop the Butterfinger bars into small pieces and set aside.
- In a large bowl, beat together the peanut butter, softened butter, granulated sugar, and brown sugar on medium speed for 2–3 minutes until light and fluffy.
- Mix in the egg, milk, and vanilla extract until smooth and creamy.
- In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet mixture, mixing just until combined. Do not overmix.
- Fold in the chopped Butterfinger candy pieces until evenly distributed throughout the dough.
- Scoop tablespoon-sized portions of dough and place them on prepared baking sheets, spacing about 2 inches apart.
- Bake for 10–12 minutes, or until the edges are lightly golden but the centers remain soft.
- Cool cookies on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
- For extra chewiness, slightly underbake the cookies and let them finish setting on the baking sheet.
- Use freshly chopped Butterfingers instead of prepackaged bits for more texture and flavor.
- Store cooled cookies in an airtight container layered with parchment paper to prevent sticking.
