Peanut Butter Cookie Bars topped with a soft chocolate fudge layer and crushed Butterfingers. You're going to want to make these...trust me!


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
  • 14 ounce can sweetened condensed milk
  • 2 bags (8 ounce each) Butterfinger Bites, crushed


  1. 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.
  2. On stovetop in small saucepan, heat sweetened condensed milk until warm. Whisk in the milk chocolate and continue stirring until smooth.
  3. Pour fudge over cookie bars. Top with crushed Butterfingers, pressing them into the fudge lightly. Allow to cool completely and cut into small bars.


**If desired, substitute refrigerated peanut butter cookie dough for the homemade version.

Comments & Reviews

  1. 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.

  2. 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!

  3. 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. )

  4. 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.

  5. 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.

  6. 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!

  7. 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.”

  8. Oh my gosh! The pictures have me drooling! What a beautiful bar! I can only imagine how wonderful it must taste!

  9. 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!

  10. These sounds SO delicious! Butterfingers are one of my absolutely favorite candy bars :).

  11. Butterfingers are my favorite candy bar.
    These cookie bars look amazing!

  12. 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!
