Made with a handful of common pantry ingredients—Butterfinger pieces, butter, sugars, flour, eggs, and vanilla—these cookie bars deliver bright sweet flavor with a satisfying crunch. They’re great for anyone who loves candy-bar-inspired desserts or wants an easy new cookie recipe to try.

Butterfinger Cookie Recipe

This recipe starts with a straightforward sugar-cookie-style dough and is enhanced by the distinctive crunch and flavor of Butterfinger chips or crushed bars. Baking the cookies as bars makes them easy to slice and serve—no scooping or rolling required. The result is a soft, chewy bar studded with crisp candy pieces that combine peanut-buttery and chocolate notes in every bite.

Tips & Variations for Candy Bar Cookies

  • Swap the cookie base: If you prefer, use a chocolate chip, oatmeal, or classic sugar cookie base to change the texture and flavor profile.
  • Try different candy bars: If Butterfinger isn’t your favorite, substitute Snickers, Twix, or Kit Kat pieces for a different combination of textures and tastes.

How long are Butterfinger cookie bars good for?

Stored in an airtight container at room temperature, Butterfinger cookie bars stay fresh for up to 5 days. Refrigerate to extend freshness to about a week. To keep bars softer longer, place a piece of bread in the container—the cookies will absorb moisture from the bread and remain tender.

Tips for storing cookies

Follow these storage tips to maintain flavor and texture:

How do I use Butterfinger candy bars instead of chips?

Unwrap the bars, place them in a zip-top bag, and crush with a rolling pin or pulse in a food processor until you have about 2 cups of small pieces. That’s roughly 4 king-sized or 5 regular-sized bars, depending on size.
