In a medium mixing bowl, add the softened butter and peanut butter. Using a stand mixer or hand mixer, mix on medium speed until combined.
¼ cup salted butter, 1 cup creamy peanut butter
Add the graham cracker crumbs and confectioners’ sugar. Mix on medium speed until combined. The mixture should be crumbly.
1 cup graham cracker crumbs, 2 cups confectioners’ sugar
Add the milk and mix to incorporate. The mixture should be thick and no longer crumbly.
1 tablespoon milk
Line a baking sheet with parchment paper.
Using your hands, take about 1 tablespoon of dough and roll it into a ball. Set aside and repeat with the remaining dough.
Place the dough balls in the freezer to harden for 15 minutes.
Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring in between, until smooth.
12 ounces milk chocolate
Remove the dough balls from the freezer. Working one dough ball at a time, dip the ball in the melted chocolate. Use a fork to move the ball around, ensuring it's fully coated. Lift the ball with the fork and gently tap it against the side of the bowl to remove excess chocolate. Transfer back to the baking sheet and repeat with the remaining dough balls.
Place the baking sheet back in the freezer for 10 minutes to allow the chocolate to harden.
Melt the white melting wafers in the microwave until smooth. Drizzle the melted wafers onto the chocolate-covered peanut butter balls using a piping bag or a spoon. Set aside for 5 minutes to harden. (Optional)
¼ cup white melting wafers
Once the chocolate has hardened, enjoy!
