Preheat oven to 350°F and line an 8x8 pan with parchment paper.
In a bowl, mix together the peanut butter, eggs, vanilla, and coconut sugar until well combined.
Mix in the dry ingredients until you have a sticky dough. Press into the prepared pan and bake for about 15 minutes. Allow to cool.
Slice the base into 9-12 bars. Spread about 1-3 tablespoon of marshmallow fluff (depending on how much you want on each cookie bar!) onto each bar and use a baking blow torch to "toast" the marshmallow fluff before enjoying!
