Introduction: Peanut Butter Cup Frappuccino Recipe

About: Community Manager for Instructables and Tinkercad.

With Halloween over, everyone must be enjoying their candy (from trick-or-treating and leftovers). So I thought I'd share a candy-inspired frappuccino recipe. This Peanut Butter Cup Frappuccino emulates these delicious peanut-buttery treats: Reese's Peanut Butter Cup and Reese's Pieces.

I've only come across one Starbucks secret recipe version for this, but since Starbucks has limited syrups, it doesn't appear to come out right. That version mixes Toffee Nut and Caramel, but since I found Peanut Butter Torani at the store, I just went with that :)

Step 1: Supplies

This recipe is a single serving and makes about the equivalent of a 16oz Grande from Starbucks.


I did 1 tbsp chocolate and 3 tbsp peanut butter and at first it seemed a bit weak, but got stronger as the drink melted, so I wanted to put a range in case you want it stronger and/or you want more of one flavor or another. It seems like the chocolate is pretty strong compared to the peanut butter so you probably want less in comparison to get a good balance.


Alternative Ways to Make It


Replace coffee with milk (or whatever you are using).

Peanut Butter Version

You can try making it with peanut butter instead of the syrup. I have done this before and it works, but it changes the texture of the drink because of the Peanut Butter. My husband preferred it this way and compared it to the texture of a protein shake.


You could cut up/mash up Reese's peanut butter cups (probably 1 to 3 would do like I did with the Oreos in my Oreo Frappuccino) or Reese's pie es and blend them in with the drink. Probably be similar to using chocolate chips like in my Double Chocolaty Chip Frappuccino.


  • Blender - I use a Magic Bullet at home, it's great for making individual drinks though doesn't blend quite as well as the Vitamix
  • Ice cube trays - small ice cubes make for even easier blending
  • Measuring cups and spoons
  • Cups for serving
  • Straws

Step 2: Blend

Time to mix up all of your ingredients. If you want to throw any candies in, I would suggest cutting/mashing them up a little first and then throwing them in to blend with everything else.

Step 3: Top and Enjoy

Time to top it and enjoy!
