Add peanut butter and maple syrup to a mixing bowl. Combine well with a fork or whisk.
Add in cocoa powder and chocolate protein powder into the bowl. Mix well again until a thick dough is formed. You want to make sure it is as smooth as possible, so it may take a little bit of arm power!
Spoon a tbsp size portion of dough into your hand and create a circle / ball using your palms. Place each ball individually on a cookie sheet or small tray. The mix should make 10 to 12 balls.
Place in the fridge for 20 minutes to harden. While the truffles are setting in the fridge, melt the chocolate chips. Add them into a microwavable bowl and set on medium heat for 2 minutes. Mix at 1 minute and put back in. Depending on your microwave and size of the chips, they may need more than 2 minutes to melt.
Pour/drizzle melted chocolate over the truffles or dip the truffles directly into the bowl of melted chocolate. Sprinkle with sea salt, coconut flakes or crushed nuts. Let the chocolate harden and then store back in the fridge!
