If you love the combination of chocolate and peanut butter, you will LOVE this Ultimate Peanut Butter Chocolate Milkshake! It is made with chocolate ice cream, peanut butter, and Reese’s peanut butter cups, served in tall glasses with a peanut butter rim pressed with chopped Reese’s Pieces for extra crunch. Oh, and that’s not all! I topped each shake with whipped cream, more peanut butter cups, extra Reese’s pieces, and a drizzle of chocolate syrup! It had to live up to the ultimate name, and each indulgent sip does just that! For another creamy, dreamy drink, check out my Oreo Milkshake, too!

Ingredients & Substitutions

  • Peanut Butter Rim: The peanut butter rim is made by spreading creamy peanut butter around the top of the glass and then rolling it in chopped Reese’s Pieces for a crunchy, peanut buttery finish. I could just lick the rim off before even filling it with the shake! I placed the glasses in the freezer for a few minutes so the peanut butter wouldn’t melt and slide down the glass.
  • Chocolate Ice Cream: For the creamiest ice cream, try my no-churn chocolate ice cream. You will love it on its own as well as for this shake!
  • Milk: I added about 3/4 cup of whole milk for the perfect consistency of the shake (at least how thick I think a milkshake should be). Add more if you want a thinner consistency. Or, start with less for an even thicker shake.
  • Peanut Butter Cups: If you don’t have miniature Reese’s peanut butter cups, simply break apart the larger cups into smaller pieces before blending. You can also make homemade peanut butter cups to use!
  • Peanut Butter: Besides the rim, I added creamy peanut butter to the shake itself. When I tasted the shake, it was the perfect blend of chocolate and peanut butter! If you prefer a chunkier texture, you could use crunchy peanut butter instead.
  • Toppings: To make this milkshake even more indulgent, don’t forget about the toppings! I added whipped cream, more chopped Reese’s peanut butter cups, Reese’s pieces, and a drizzle of chocolate syrup. It looks as impressive as it is delicious!

Can I Use A Different Flavor Of Ice Cream?

Yes, you can definitely use a different kind of ice cream! If you prefer vanilla, chocolate peanut butter (for even more peanut butter flavor!), or even salted caramel ice cream (yum!), they will all work well. Just keep in mind that it will change the flavor slightly, but it’s a great way to customize your milkshake to your taste!

How To Adjust The Thickness Of Your Ultimate Peanut Butter Chocolate Milkshake

To make your milkshake thicker, add more ice cream. If it’s too thick, add a little more milk. Keep adjusting until it’s just how you like it!

Can I Make This Peanut Butter Chocolate Milkshake Without A Blender?

Yes, you can make the milkshake without a blender by using a hand mixer. Just put the chocolate ice cream, peanut butter, and milk in a big bowl and mix until smooth. If you don’t have a hand mixer, you can soften the ice cream a little and stir everything together by hand. It may take a bit longer (and be a good arm workout!), but it will still work. Don’t forget to break the Reese’s Peanut Butter Cups into smaller pieces before adding them for easier mixing!

How To Store Your Peanut Butter Chocolate Milkshake: Refrigerator & Freezer Tips

Although best served immediately, you can save your milkshake for later. Here is how:

Refrigerator: Store in an airtight container in the refrigerator for up to 24 hours. Shake or stir well before drinking to recombine any separated ingredients.

Freezer: If freezing, store the milkshake in an airtight container for up to a week. When ready to enjoy, let it thaw in the refrigerator for a few hours or at room temperature for 15-30 minutes. Then, stir or blend to restore the creamy texture.

Add toppings when ready to serve (or if you want to enjoy a shake yourself)!
