Add all the ingredients to a blender jar. Pulse to combine the ingredients (about 60 seconds).
Fill the popsicle molds with the blended mixture. I use this popsicle mold set from Tovolo. I've had this set for a few years now. I've also heard good things about this set.
Freeze the popsicles for at least 6 hours.
Rinse the outside of the molds with warm water to help easily release the popsicles from the molds. Store any leftover popsicles in an air-tight container in the freezer.
Notes
*If your peanut butter is salty (all brands will differ), you'll probably want to skip the pinch of salt in the recipe. Also, if you're a big peanut butter fan, feel free to increase the total amount to 1/2 cup of peanut butter. I've done this a couple of times and really love/prefer the peanut butter flavor it offers. Dustin prefers the 1/3 cup peanut butter ones. ** The avocado is optional. It provides additional healthy fat and creaminess. You won't taste the addition of the avocado. This recipe makes 5-6 popsicles using the Tovolo molds linked to in the recipe instructions. The number of popsicles made will depend on the popsicle mold used. The filling makes about 3 cups.
