Combine Greek yogurt, peanut butter, peanut butter powder, maple syrup, and gelatin in blender. Blend until well combined. Place in the freezer while you slice bananas into approx 1/2-inch slices.
Take mixture out of freezer and place one spoonful on top of each banana slice. Place banana slices back in freezer while you prepare the chocolate coating.
Melt coconut oil and butter until liquid (this takes approx no time so keep your eyes on it... I melt it in a mug in my toaster oven). Stir in cacao. Take your topped banana slices out of the freezer and cover them in you chocolate mixture. If you're going to add toppings, add them immediately as the chocolate hardens pretty quick. I love topping mine in hemp hearts and coconut. Chris loves chocolate and paleo granola... you do you :)
