Butterfinger Fudge Cookie Bars are peanut butter cookies, topped with a soft chocolate fudge layer and crushed Butterfingers. A decadent combo of sweet, nutty, crunchy flavors no one can resist!
What happens when you combine a Butterfinger fudge recipe with 3 ingredient peanut butter cookies? Today’s cookie bars are the answer!
Why These Cookie Bars Are Best
A Butterfinger Fudge Cookie Bar that’s going to have everyone begging you for the recipe.
- Chewy peanut butter cookie base.
- Easy 3 ingredient fudge topping.
- Real Butterfinger candy bars on top!
This is a dense, fudgy cookie bar with a satisfying crunch from the crushed Butterfingers on top. Every bite is loaded with sweetness balanced with a hint of salt from the peanut butter.
Serve them with a big glass of milk or a mug of hot chocolate for a crowd-pleasing sweet treat!
Ingredient Notes
- Peanut butter – Use the standard shelf stable variety, not the refrigerated kind you have to stir for best results.
- Milk chocolate morsels – These are the base for the fudge topping. For a dark chocolate twist, use semi-sweet morsels instead.
- Sweetened condensed milk – It’s combined with the chocolate to make the fudge. Don’t try to substitute evaporated milk—trust me!
- Butterfinger bites – These are bite-sized versions of the full candy bar that are easy to crush.
Tips and Tricks
- This recipe starts by making a peanut butter cookie dough from scratch. For an even quicker and easier option, use a roll of store bought refrigerated peanut butter cookie dough instead!
- Make the fudge while the cookie bars are baking. By the time the bars are done, the fudge will be ready to pour on top.
- Press the crushed Butterfingers onto the fudge while it’s still warm.
- Let the bars cool completely before cutting. The bars will be soft and gooey at first but they will firm up as they set and cool.
Recipe FAQs
Place the Butterfinger bites in bag with a zip top. Use a mallet or rolling pin to crush the candies into coarse pieces. They don’t need to be evenly sized or completely pulverized. The variety of textures adds to the deliciousness!
Store these bars in an airtight container at room temperature. If your house runs warm, you may want to refrigerate them to help them hold their shape. They keep well for about a week but cookie bars always disappear long before then in my house!
The Butterfingers will lose their crunchiness the longer you store them, but the flavor will still be delicious.
This Butterfinger Fudge Cookie Bars recipe was tested in a half sheet pan ( 15 x 10 x 1 inches). You can use a 9×13 pan instead, but the cookie bars will be thicker and take longer to bake.

- For the cookie bars, beat butter and brown sugar in mixing bowl until combined. Add peanut butter. Beat in egg and milk. Beat in the flour, salt and baking soda. Press dough into a 15x10x1 baking sheet lined with parchment paper. Dough will be sticky, I dipped my fingers in flour before pressing. Bake in a 375 degree oven for 15-18 minutes. Remove from oven.

Cookies, peanut butter and fudge—three of life’s best things come together in this recipe for Butterfinger Fudge Cookie Bars!
I am making these today for a special man 🙂 I know he is gonna love em!
Oh my lordy lord, this looks amazing! x
Oh. My. God. I do want to make these! They look divine 🙂
As a kid, I ate Butterfingers like nobody’s business. Butterfinger blizzard? I’m all over that! I get the urge to have one every now and then and I remember how much they stick in my teeth. Then I’m good for about six months. These bars? I need them.
Butterfingers used to be my favorite as a kid, but I haven’t had them in years. The whole thing at once just gets too stuck in my teeth and they’re so sweet. But broken up and used as a topping sounds perfect!
I have what I call my “baking shelf”. Then there is the corner of the counter full of different flours. Then there is the “secret” baking stash of candy bars, mini candy bars, and candy bar bites. I buy them when they are on sale or end of a holiday and hoard them until a recipe like this one comes along. 🙂 Now I know what my Butterfingers are for. (We won’t talk about the additional bags remaining even after I make these. )
It’s pretty much a guarantee that if it has butterfingers, I”m going to love it! These look amazing Aimee. Have fun this weekend at BHF! Wish I could’ve made it.
Oh my gosh. These sound absolutely amazing! All of your Butterfinger recipes sound so good – i actually never realized how deep my love of Butterfingers was until one Halloween I bought a bag to give out and ended up eating them all beforehand. Love. Butterfingers.
Aimee, Gosh these look divine! I always wanted Butterfingers most of all, in my Halloween candy! My kids will love these! Bar cookies are one of my favorite things to bake and share, too. LOVE your blog! Fantastic pictures!
ummm.. YUM!!!!
Mmm. These look fabulous! I think I would eat the whole pan!
WHOA BABY! These bars are calling my name. I haven’t had a Butterfinger in years. Remember when they used the Simpsons in all of their commercials decades ago? “Nobody better lay a finger on my Butterfinger.”
Heaven in a bar:)
These are some beautiful cookie bars!
Oh my gosh! The pictures have me drooling! What a beautiful bar! I can only imagine how wonderful it must taste!
Are you and my husband related? He stockpiles Butterfinger bars too and they seem to hide out in the pantry in random places… He need to find his stash so I can make him these!
Can you bring a dozen of these to Austin? YUMMO
These sounds SO delicious! Butterfingers are one of my absolutely favorite candy bars :).
Butterfingers are my favorite candy bar.
These cookie bars look amazing!
I’m a gigantic Butterfinger lover, just as you describe yourself. I’ve seen the mini ones and I’m so afraid to buy them because they’ll be calling my name if I don’t use them immediately. These bars are the perfect vehicle for them. I gotta do this soon!
