In a bowl, mix together the peanut butter, protein powder (if using), maple syrup and cashews until well combined.
1 cup peanut butter, 1 scoop protein powder, 2 tablespoons pure maple syrup, 1 cup cashews
Using a mini muffin tray, scoop a tablespoon sized amount of mixture into each muffin hole. Press down firmly so the base is even. Repeat until all the mixture is used.
In a heatproof bowl, melt the chocolate chips and coconut oil together (microwave in 30 seconds bursts).
1/2 cup mini chocolate chips, 1 tablespoon coconut oil
Spoon the melted chocolate over each peanut butter base until the tops are covered.
