In a large bowl, add the peanut butter, coconut flour, maple syrup, vanilla, and sea salt. Stir until fully combined and a ball forms.
Add the dough ball to a parchment lined 9x9 baking dish. With damp hands or a spatula, evenly spread the dough to form 1 flat layer. Set aside.
In a small bowl, melt your chocolate or prepare your own chocolate mixture by adding melted coconut oil, cocoa or cacao, and maple syrup and stir until combined.
Pour you melted chocolate over your prepared peanut butter base. Spread with a spatula into an even coating. Set in the fridge until set, at least 30 minutes. Sprinkle with sea salt once set, optional.
