In a bowl, whisk together the malted milk powder, powdered sugar, cocoa powder, and salt.
In a separate bowl, whisk together the milk and vanilla extract.
Add the wet ingredients to the dry ingredients and stir until everything is combined.
Place the mixture in the fridge for 30 minutes to firm up.
Once it’s firm, use a spoon or your hands to roll the mixture into balls.
Place the balls on a parchment paper-lined baking sheet and freeze for 30 minutes.
Melt the chocolate in a double boiler or a bowl that can go in the microwave.
Place each ball back on the parchment paper after being covered in chocolate.
Freeze for another 30 minutes or until the chocolate is firm.
Store the balls in an airtight container in the fridge for up to 2 weeks.
