Preheat the Oven: Preheat your oven to 180°C (350°F). Line a baking tray with parchment paper.
Prepare the Crust: In a mixing bowl, combine coconut flour, oat flour, melted coconut oil, and honey (or maple syrup). Mix until it forms a dough-like consistency.
Bake the Crust: Press the crust mixture evenly into the prepared baking tray. Bake for 10-12 minutes, or until golden brown. Remove from the oven and let it cool completely before adding the peanut butter layer.
Prepare the Peanut Butter Fudge Layer: In a bowl, mix the peanut butter, melted coconut oil, salt, vanilla extract, honey (or maple syrup), and chocolate chips until well combined. If needed, gently warm the mixture in the microwave or on the stovetop until smooth.
Assemble the Bars: Pour the peanut butter fudge mixture over the cooled crust, spreading it evenly. Place in the freezer for a few hours until the fudge layer is set.
Add the Chocolate Drizzle: Melt additional chocolate chips (if desired) and drizzle over the top of the fudge layer.
Serve: Slice into bars and enjoy! Store any leftovers in the refrigerator.
