On a Dessert Platter
- Arrange these cookies on a beautiful platter with other treats like brownies or bars for an inviting dessert spread at any gathering.

How to Perfect Peanut Butter Butterfinger Cookies
Perfecting your Peanut Butter Butterfinger Cookies is all about attention to detail. Here are some tips to ensure they turn out just right.
- Use Softened Butter: Make sure your butter is softened to room temperature for the best texture. This helps create a creamy mixture that’s easy to whip into fluffiness.
- Don’t Overmix: Mix just until ingredients are combined. Overmixing can lead to tough cookies, so stop when you see no dry flour left.
- Chill the Dough: Chilling the dough before baking allows the flavors to meld and results in thicker cookies. Aim for at least 15 minutes but feel free to chill longer!
- Measure Flour Correctly: Spoon flour into your measuring cup rather than scooping directly from the bag. This prevents compacting and ensures you have the right amount, leading to softer cookies.
- Watch Baking Time: Keep an eye on your cookies as they bake. They should look set at the edges but still soft in the middle when you take them out.
- Cool Properly: Allow cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. This helps them firm up without breaking apart.

Best Side Dishes for Peanut Butter Butterfinger Cookies
While these cookies shine on their own, pairing them with side dishes can elevate your dessert experience further. Here are some ideas:
- Vanilla Ice Cream: A scoop of creamy vanilla ice cream pairs beautifully with warm cookies, creating a delightful contrast in temperature and texture.
- Chocolate Sauce: Drizzling melted chocolate sauce over your cookie adds richness and enhances its decadent flavor profile, making each bite heavenly.
- Fresh Berries: A side of fresh strawberries or raspberries offers a refreshing tartness that balances out the sweetness of the cookies perfectly.
- Whipped Cream: Light, fluffy whipped cream can be served on the side for dipping or topping, adding an airy creaminess that complements rich flavors.
- Milkshake: Blend up a simple milkshake using vanilla ice cream and milk as a fun drink pairing that mirrors classic childhood treats.
- Fruit Salad: A light fruit salad provides a healthier contrast while adding brightness to your dessert table, complementing the richness of Peanut Butter Butterfinger Cookies.
- Coffee or Espresso: For adults, serving coffee or espresso alongside creates an elegant touch that enhances relaxation while enjoying dessert time.
Common Mistakes to Avoid
When making Peanut Butter Butterfinger Cookies, it’s easy to overlook crucial steps. Here are some common mistakes to avoid for the best results.
- Using natural peanut butter: Natural peanut butter can alter the texture and consistency of your cookies. Stick with regular peanut butter brands like Jif or Skippy for a better outcome.
- Overmixing the dough: Overmixing can lead to tough cookies. Mix the ingredients just until combined, and stop when you see some flour still visible.
- Skipping the chilling step: Chilling the dough helps prevent spreading too much during baking. Aim to chill for at least 15 minutes, or even longer if you have time.
- Not measuring flour properly: Improperly measured flour can lead to dry or dense cookies. Use the spoon-and-level method to ensure accurate measurement.
- Ignoring baking times: Every oven is different, so keep an eye on your cookies as they bake. They should be set at the edges but not shiny in the middle.
Storage & Reheating Instructions
Refrigerator Storage
- Store Peanut Butter Butterfinger Cookies in an airtight container for up to 3 days.

Freezing Peanut Butter Butterfinger Cookies
- Place cookie dough balls in a ziplock bag and freeze for up to 3 months.
