Ingredients You’ll Need

Cookie Dough Base

• 3/4 cup butter, softened — provides richness, structure, and soft cookie texture
• 1/2 cup granulated sugar — adds sweetness and helps create crisp edges
• 1/2 cup packed brown sugar — adds moisture, chewiness, and caramel depth
• 1 cup creamy peanut butter (not natural) — creates signature peanut flavor and soft structure
• 1 large egg — binds ingredients and adds structure
• 1 1/2 teaspoons vanilla extract — enhances sweetness and overall flavor balance

Dry Ingredients

• 1 1/2 cups all-purpose flour — provides structure and stabilizes dough
• 1/2 teaspoon baking soda — helps cookies rise and spread properly
• 1/2 teaspoon baking powder — adds lift for a thick, soft texture
• 1/4 teaspoon kosher salt — balances sweetness and enhances peanut flavor

Mix-In

• 16 ounces Butterfinger candy, chopped — adds crunchy, peanut-brittle texture and caramelized sweetness throughout the cookie

Step-by-Step Instructions

1. Cream Butter and Sugars

Beat softened butter until smooth, then add granulated and brown sugar. Mix for about 2 minutes until light and fluffy for proper aeration.

2. Add Peanut Butter

Mix in peanut butter until fully incorporated, scraping down the bowl to ensure a smooth, even base.

3. Add Egg and Vanilla

Beat in the egg and vanilla extract until the mixture is fully combined and creamy in texture.

4. Mix Dry Ingredients

Add flour, baking soda, baking powder, and salt on top of the wet mixture. Stir gently into the dough until just combined to avoid overworking.

5. Add Butterfinger Pieces

Fold in chopped Butterfinger pieces until evenly distributed, being careful not to overmix so the candy remains intact.

6. Chill the Dough

Cover and refrigerate for at least 15 minutes (or up to 24 hours) to firm the dough and deepen flavor.

7. Shape and Bake

Preheat oven to 350°F and roll dough into 2-inch balls. Bake for about 10 minutes until edges are set and centers are no longer shiny.

8. Cool and Set

Allow cookies to rest on the baking sheet for 5 minutes before transferring to a rack to finish cooling and firm up.

Recipe Notes & Tips

• Don’t Overmix Dough — Overworking flour leads to dense, tough cookies instead of soft, thick texture.
• Chill for Better Structure — Even a short chill improves flavor and makes sticky dough easier to handle.
• Use Creamy Peanut Butter Only — Natural peanut butter can cause separation and inconsistent texture.
• Watch Bake Time Closely — Cookies continue to set after baking; avoid overbaking for softness.
• Press Slightly If Needed — If cookies don’t spread, gently flatten after baking for ideal shape.
• Add Extra Candy on Top — Press Butterfinger bits onto warm cookies for extra crunch and visual appeal.

Why This Recipe Works

This recipe works because the combination of butter, brown sugar, and peanut butter creates a stable, rich cookie base with both structure and moisture. The addition of both baking soda and baking powder ensures controlled spread while maintaining a thick, bakery-style lift. Butterfinger pieces introduce brittle-like sugar crystals and peanut flavor that partially melt during baking, creating pockets of crunch and caramelized sweetness throughout the cookie. At approximately 169 calories per cookie, they deliver a dense, indulgent treat with balanced fat, sugar, and texture contrast.

They’re simple to prepare yet deliver bakery-level texture and flavor, making them perfect for sharing or storing for later. With minor adjustments like added chocolate or salt, they can easily be customized while maintaining their signature soft, chunky, candy-studded appeal.
