Ingredients

Let’s take a closer look at the ingredients you’ll be using. Each one plays a special role in creating that perfect balance of chewy and crunchy, sweet and salty.

¾ cup (1½ sticks) unsalted butter, softened: The base of our cookie dough, butter adds richness and tenderness.
½ cup granulated sugar: For that classic cookie sweetness and a slight crisp edge.

½ cup packed light brown sugar: Adds moisture and a subtle caramel flavor that complements the peanut butter.
1 cup creamy peanut butter: The star ingredient gives these cookies their signature flavor and creamy texture.
1 large egg, at room temperature: Helps bind everything together and adds a bit of lift.

1½ teaspoons pure vanilla extract: Enhances the sweetness and rounds out the flavors.
1½ cups all-purpose flour, spooned and leveled: Provides structure for the cookies to hold their shape.
½ teaspoon baking soda: A leavening agent that helps the cookies rise just right.

½ teaspoon baking powder: Works alongside baking soda for a soft but sturdy texture.
¼ teaspoon kosher salt: Balances the sweetness and intensifies the peanut butter flavor.
16 oz Butterfinger candy, chopped: The crunchy candy pieces mixed right into the dough make these cookies unforgettable.

Pro tip: When chopping your Butterfinger candy bars, I like to leave some pieces a little chunky and others finely chopped. This variation gives you those surprise crunchy bites alongside smaller candy bits that melt into the cookies.

How to Make Peanut Butter Butterfinger Cookies

Ready to get baking? Follow these simple steps, and I’ll share a few little tips along the way to make sure your cookies come out perfect every time.

Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper. This prevents sticking and makes cleanup a breeze.

Cream the butter and sugars: In a large bowl, beat the softened butter on medium speed until smooth and creamy. Add the granulated sugar and light brown sugar, then continue beating for about 2 minutes until the mixture is light and fluffy. Don’t forget to scrape down the sides of the bowl to ensure even mixing.
Add peanut butter, egg, and vanilla: Mix in the creamy peanut butter until fully combined. Then crack in the egg and pour the vanilla extract, mixing until everything is well incorporated. Scrape the bowl again to catch any bits stuck to the sides.
Prepare the dry ingredients: Add the flour to the wet mixture—but don’t mix just yet! Sprinkle the baking soda, baking powder, and kosher salt over the flour. Use a spoon to gently stir the dry ingredients together, helping to distribute the leavening agents evenly.

Combine wet and dry ingredients: Turn your mixer on low and mix just until the dough begins to come together. It’s okay if a few streaks of flour remain; overmixing can make cookies tough. Stop the mixer and scrape the bowl one last time.
Fold in the chopped Butterfinger candy: Using a spatula or wooden spoon, fold the candy pieces into the dough until evenly distributed. This is where the magic happens!
Chill the dough (optional): For thicker, chewier cookies, cover the dough and refrigerate for 30-60 minutes. If you’re short on time, you can skip this step, but I highly recommend it—it really makes a difference.

Scoop the dough: Using a large cookie scoop (about 2 tablespoons), portion out dough balls onto your prepared baking sheets. Space them about 2 inches apart to allow for spreading.
Bake: Bake one sheet at a time in the center of the oven for 10-12 minutes. You want the edges to be set and lightly golden while keeping the centers soft. It’s tempting to overbake, but trust me, soft centers are the best part!
Cool and finish: Let the cookies cool on the baking sheet for at least 10 minutes. If you want, gently press down the cookies or sprinkle extra chopped Butterfinger pieces on top while they’re still warm for an extra candy crunch.

Transfer to a wire rack: Move the cookies to a wire rack to cool completely before serving or storing.

Substitutions & Additions

One of the best parts about baking is making a recipe your own. Here are some substitutions and fun additions you might consider for these Peanut Butter Butterfinger Cookies:

Butter substitute: You can swap the unsalted butter for coconut oil or vegan butter if you prefer a dairy-free option. Keep in mind the texture may shift slightly.
Peanut butter swap: Feel free to use natural peanut butter, but make sure it’s well stirred and smooth. Almond or cashew butter are lovely alternatives if you’re looking for a nutty twist.
Butterfinger alternatives: If Butterfinger candy isn’t your favorite or hard to find, chopped Heath bars, toffee bits, or even crushed pretzels will add a similar crunchy sweetness.

Chocolate boost: Mix in chocolate chips or drizzle melted chocolate over cooled cookies for an extra indulgence.
Nutty upgrade: Add chopped peanuts or chopped pecans for extra crunch and flavor complexity.
Spice it up: A pinch of cinnamon or a dash of cayenne pepper can add a surprising depth and warmth to the cookie dough.

Experimenting with additions like these will make your baking adventures even more exciting. For a fun no-bake treat with a peanut butter twist, check out my recipe for No-Bake Peanut Butter Pie, which is also a crowd favorite.

Tips for Success

When baking Peanut Butter Butterfinger Cookies, a few simple tips can elevate your results from good to spectacular:

Measure flour carefully: Spoon the flour into your measuring cup and level it off with a knife. Too much flour can make cookies dry and dense.

Room temperature ingredients: Make sure your butter and egg are at room temperature for easier mixing and a smoother dough.
Don’t overmix: Once you add the flour, mix just until combined to keep your cookies tender.
Chill the dough: If you have time, refrigerate the dough before baking. This helps control spreading and results in thicker, chewier cookies.

Watch your baking time: Oven temperatures vary, so start checking cookies at 10 minutes. The edges should be set and golden but centers still soft.
Use parchment paper or silicone mats: This prevents sticking and helps your cookies bake evenly.
Cool on the baking sheet first: Let the cookies rest on the sheet for at least 10 minutes before moving them to a wire rack. They’ll firm up nicely without breaking.

Planning ahead? You can make the dough a day in advance and keep it tightly wrapped in the fridge. This not only saves time on baking day but also enhances the flavors. Plus, if you love baking cookies, you might enjoy my easy-to-follow Earl Grey Cookies—a perfect pairing for afternoon tea.

How to Store Peanut Butter Butterfinger Cookies

Storing your cookies properly will keep them fresh and delicious for days. Here’s how to do it:

Room temperature: Place cooled cookies in an airtight container. They’ll stay fresh for up to 4 days.

Refrigeration: If your kitchen is warm or you prefer firmer cookies, store them in the fridge for up to a week. Just remember to bring them to room temperature before serving for the best flavor.
Freezing: You can freeze baked cookies or the dough itself. For baked cookies, layer them in a freezer-safe container with parchment paper between layers, and freeze for up to 3 months. To bake from frozen dough, thaw overnight in the fridge, then bake as usual.

When you want to enjoy a fresh batch without the hassle, this storage method can be a real lifesaver. It’s perfect for those busy weeks when you want to treat yourself or your family to something sweet without starting from scratch.

FAQs

Can I use crunchy peanut butter instead of creamy?

Yes! Using crunchy peanut butter will add even more texture to your cookies, complementing the Butterfinger bits nicely. Just be aware that the dough might be a bit chunkier.

What if I don’t have Butterfinger candy bars?

No worries! You can substitute with Heath bars, toffee bits, or even crushed pretzels for that satisfying crunch and sweet flavor.

Can I make these cookies gluten-free?

Absolutely. Swap the all-purpose flour for a gluten-free baking blend that measures cup-for-cup. Just check the blend includes xanthan gum for best texture.

How do I prevent my cookies from spreading too much?

Chilling the dough before baking is the key. Also, make sure your butter isn’t too soft or melted when you mix the dough. Using parchment paper or silicone mats helps as well.
