Using a microwave, melt chocolate, coconut oil and peanut butter together in thirty second increments until melted and combined.
Add rice puffs, coconut, salt and collagen (if using). Use a spatula to combine the ingredients, making sure everything is coated in chocolate.
Divide the mixture between eight cupcake liners and place in the freezer for approximately twenty minutes to set.
Remove from the freezer and serve straight away or store in an air tight container in the fridge for up to one week
Notes
*100g of chocolate is equal to one block of Lindt 70% or 85% excellence chocolate.** I recommend leaving the chocolate crackles at room temperature for at least five minutes before serving as they can be very hard straight from the freezer.
