Why This Recipe Works

  • Taste just like the Crumbl muddy buddy cookies. The Crumbl Peanut Butter Cookies taste delicious with the melted chocolate topping and muddy buddy pieces. It will be like you got your cookies from the store — except without the extra cost! 
  • Muddy buddies in cookie form. I am in Crumbl cookie muddy buddy heaven with this recipe! When I saw this muddy buddy Crumbl cookie I just knew I needed to make a copycat! I love Muddy Buddies! They are a frequently requested treat among my kiddos. If you love them too, then be sure to save this cookie version as one of your muddy buddy recipes! 
  • Rich peanut butter flavor. The peanut butter cookie recipe has 3/4 cup peanut butter in it! This really helps bring out the flavor in the cookies.  

Ingredient Notes

Crumbl Muddy Buddy Cookie ingredients portioned into glass bowls on a tan textured background.
  • Unsalted Butter: If using salted butter instead of unsalted, reduce the amount of salt 1/4 of a teaspoon per 1/2 cup of butter in the recipe. 
  • Creamy Peanut Butter: For a crunchy element to the cookies you can use crunchy peanut butter if you’d prefer. Don’t use natural peanut butter as the added oil isn’t accounted for in this recipe. 
  • Milk Chocolate: You can use baking chocolate cut up or chocolate chips. 
  • Vegetable Oil: The vegetable oil helps the chocolate melt better and stay smooth. Feel free to use vegetable shortening or coconut oil as substitutes if preferred. 
  • Muddy Buddies:Make ahead of time or use leftovers from a previous dessert/treat night. 
  • Powdered Sugar: Adding the sprinkle of powdered sugar to the tops of the cookies helps them feel more like a muddy buddy Crumbl cookie. 

Step-by-Step Instructions

  1. Cream butters and sugars. Add the butter, peanut butter, brown sugar, and ¼ cup of granulated sugar to the bowl of a stand mixer (or with a hand mixer) and cream for 2-3 minutes. Add the egg and vanilla and mix again until combined.
  2. Add dry ingredients. Add the salt, baking soda, and flour and mix until combined.

  1. Portion into balls. Using a 1/4 cup, form into balls. Press down gently on each ball to make a very thick disk. Place 6 on a parchment paper-lined baking sheet.
  2. Bake. Bake at 350°F for 11-12 minutes. The cookies will look crackly and the centers slightly underdone. Remove from the oven and let rest on the baking sheet for 10 minutes. Transfer to wire rack to cool completely.

  2. Make the chocolate topping. While the cookies are resting/cooling, add the milk chocolate and vegetable oil to a microwave-safe bowl. Microwave until melted, stirring every 20 seconds. 
  3. Add chocolate topping to cookies. Spread 1-2 tablespoons of the melted chocolate on each peanut butter cookie. 
  4. Top with muddy buddies. Place a few muddy buddy pieces on each cookie. Dust with powdered sugar.

Recipe Tips

When adding the dry ingredients to the wet, mix until the dough just forms. You don’t want to over mix the cookie dough at this stage or else the dough will become tough.

This is a great recipe to make a day or two after making Muddy Buddies and you want to repurpose them for a different dessert. 

Add a bit of vegetable oil to the chocolate will help it melt easier and stay smooth. You can use vegetable shortening or coconut oil instead. 

If you want a crunchy texture to the Crumbl peanut butter cookies, you can use crunchy peanut butter instead of creamy. 

I don’t recommend using a natural peanut butter. Natural peanut butters typically have oil separation. This added oil isn’t accounted for in this recipe so it would affect the texture and bake of the cookies.

Make Ahead, Storing, and Freezing

Store the cookies in an airtight container at room temperature for 2-3 days or in the fridge for 3-4 days. 

To freeze the cookies, let the cookies cool completely. Flash freeze the cookies on a sheet until the chocolate topping is solid. Wrap each cookie in plastic wrap and store in an airtight container or Ziplock bag. Freeze for up to 2 months. Remove and let thaw.

To freeze the peanut butter cookie dough, roll into balls and flatten into the thick disks. Flash freeze on a baking sheet until firm. Transfer to an airtight container or Ziplock bag. Bake from frozen. You may need to add an additional minute onto the bake time.

Recipe FAQs

Do I have to add muddy buddies?

No you don’t! Adding them really sends the message that this is a Crumbl muddy buddy cookies recipe, but it isn’t absolutely necessary. Simply having the peanut butter cookie, chocolate topping and powdered sugar dusting will give a nod to what dessert you are recreating in cookie form. 

Can I use crunchy peanut butter?

Yes you can. If you want a bit of that crunchy peanut butter texture in the cookies then go for it! I like the smooth texture so I opted for creamy. 

Can I use natural peanut butter?

I don’t recommend it. Natural peanut butters have more oil separation. That hasn’t been accounted for in this recipe so it could affect the texture and bake of the cookies.
