Add the peanut butter and powdered sugar to the mixing bowl and with the electric mixer on low speed mix it in. It will be crumbly.
Slowly add the vegan whipped cream until you achieve a thick consistency that you can easily roll into balls. You may not need to add all your whipped cream, it depends on the brand of peanut butter you're using, so go slow when you add in the whipped cream.
Roll the peanut butter mix into balls - aim to get 20 balls - and place them evenly on a parchment lined baking tray.
Place them into the freezer for a couple of hours until the balls have set solidly.
Place the vegan chocolate into a microwave safe dish. Microwave in 30-second intervals, bringing it out to stir every 30-seconds until your chocolate is melted. Add in the coconut oil and stir it in (makes the chocolate a little thinner and easier to work with).
Place each ball into the melted chocolate and use two teaspoons to cover it in chocolate and then lift it out and place it back onto the parchment lined baking tray. Sprinkle with crushed peanuts (optional).
When all the balls are covered in chocolate, place in the fridge for around 10 minutes for the chocolate to set.
Keep the balls stored in the fridge and serve directly from the fridge.
