In a large skillet, melt the butter over low heat.
4 Tablespoons (57 g) salted butter
Stir in the peanut butter until completely combined.
¾ cup (190 g) creamy or chunky peanut butter*
Add the marshmallows and stir continuously until they have melted and dissolved into the peanut butter mixture.
3 cups (150 g) mini marshmallows
Turn the heat off and stir in the vanilla.
1 teaspoon vanilla
Fold in the rice krispie cereal until completely coated.
2 cups (80 g) crispy rice cereal
Let the mixture cool enough so you can touch it. Use a 1.7 Tablespoon cookie scoop or large spoon to scoop the mixture. Roll it into a ball with your hands. Place on a plate or small baking sheet lined with parchment.
Repeat with the remaining Rice Krispie mixture. Space the balls so they are not touching. Chill in the freezer for 30 minutes.
While the peanut butter balls chill, in a small pan, melt the coconut oil over low heat.
1 ½ Tablespoons coconut oil*
Add the chocolate and continue to stir until melted.
12 ounces semi-sweet chocolate*
Dip each ball into the chocolate and place back on the parchment paper so they are not touching. Store in the fridge. Once hardened, transfer to an airtight container or bag.
sprinkles or candy decorations, optional*
