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.

Butterfinger Fudge Cookie Bars
Ingredients
For the Cookie Bar:
- ¾ cup unsalted butter softened
- 1 ¼ cups light brown sugar packed
- ½ cup creamy peanut butter
- 1 large egg
- 2 Tablespoons milk
- 1 ¾ cups all-purpose flour
- ½ teaspoon kosher salt
- 1 teaspoon baking soda
For the Topping:
- 12 ounce milk chocolate morsels

Instructions
- 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.

- Pour fudge over cookie bars. Top with crushed Butterfingers, pressing them into the fudge lightly. Allow to cool completely and cut into small bars.

Cookies, peanut butter and fudge—three of life’s best things come together in this recipe for Butterfinger Fudge Cookie Bars!
I love candy bars but never eat them nearly as much as I would like! This sounds great and I seriously need to try one of your cookie candy bars!
Wow! Now this is definitely a “sugary sweet” haha. What an awesome looking cookie bar! They would be devoured in this house, for sure.
These sound amazing! I noticed you mentioned Rollos at the end of your blog and had to reply. I am sure you have a good idea as what to do with them, but I just wanted to share my thought as to how to use them. I like to cheat and use the cookie mixes from a bag, not cool I know. I also like to make them in mini muffin tins. So after your cookie bakes just take a rollo and shove it down in the middle of the cookie! Most excellent surprise when you bite into the cookie! Hope you try it and enjoy!
I have never been a BIG butterfinger fan, but my kids sure are…these may just change my mind
Ahhhhhhh!!! I love butterfingers too and I am obseeeesssed with these! SO GOOD
These are amazing! Wish I had some Butterfingers in my cupboard so that I could make these today!
I loooooove butterfingers!!! Total drool city over here looking at these!
I always look in the candy aisle for inspiration, but I know it would be dangerous to actually buy anything! These look amazing- I love butterfingers!
I’ll take one of everything please! Those butterfinger fudge cookie bars are going to be made in this house very soon!
Oh come to mama!!!!
So so evil in such a good way 😉
I have the same problem of stocking my cupboards with bags of candy and then forgetting about it. There was a bag of butterfingers in mine a few weeks ago that I had forgotten about…it became cookies pretty quickly! I wish I had this recipe then, because girl, this looks awesome!!! Love that fudge candy layer!!!
LOL, I need to do that with my pantry. I think that will go on my summer bucket list. I’m kind of afraid of what I’ll find!
If only I could find enough candy for these bars. OMG Aimee! Bring me some tomorrow? You’re checking bags, you know you have room. 😉
These look like pure heaven!! Butterfingers and peanut butter are my favorite! just pinned!
I think I’ve gone to Butterfinger heaven! Can’t wait to try these!
The soft fudge topping with crush Butterfingers! OMGosh Aimee, this is making me so hungry. I am going to start hoarding BFs just so I can make this recipe. 🙂
LOL Elaine. As you share a skinny recipe today. Hmmm, balance??
Hahaha! I love it! Well…this is an obsession we share, Aimee. I, too, pined for Reese’s (my biggest weakness) and Butterfingers growing up. Clark Bars were acceptable if Butterfingers were nowhere in sight. And, oh girl! I have baked peanut butter cookies with chopped Butterfinger candy bars in the dough as well! Thanks for sharing!
Glad others are as obsessed with Butterfingers as I am!
Wow you love your BFs! I love seeing the backlinks! And these new bars – with BFs, PB, chocolate, all kinds of texture, they’re right up my alley! I love BFs too!
Isn’t it funny that everytime I make something with peanut butter, I think of you 🙂
LOL and I’m honored! 🙂
wow, this looks amazing! Unfortunately, I never have the problem of losing candy in my pantry — I think about it constantly until I eat it 🙂
It’s a special talent to buy candy and lose it!!
Mmm what a fabulous treat! These sound awesome!
Thanks Katrina! Have a great day!!
