Combine 3-1/2 cups of powdered sugar in a large bowl with the butter. Add in the peanut butter and the graham cracker crumbs, mixing until combined.
Using a small cookie scoop or measuring spoon, roll the peanut butter dough into 1-inch balls, then place them on a baking tray lined with parchment paper.
Once you’ve rolled all the dough, freeze the balls for about 30 minutes.
Place the remaining 1/2 cup of powdered sugar into a shallow bowl, then roll each peanut butter ball in the powdered sugar one by one. Place the coated balls back onto the tray.
Store the peanut butter snowballs in the fridge in an airtight covered container until ready to serve. Place a layer of wax paper between the layers to prevent the balls from sticking together.
Notes
This is a great recipe for children to help with, as it involves simple mixing and rolling and does not require any cooking or baking.
It's best to store them in an airtight container in the refrigerator. They can last up to a week when stored properly.
These snowballs freeze well. Place them in a freezer-safe container, and they can be stored in the freezer for up to a month.
These snowballs are perfect for making ahead as they store well in the refrigerator or freezer. Making them in advance can save time during busy holiday preparations.
