In a bowl, mix the peanut butter, maple syrup, almond flour, and a pinch of salt until you have a smooth dough-like consistency.
Line a mold or small baking tray with parchment paper, then press the peanut butter mixture into the mold, flattening it evenly.
Melt the chocolate with the neutral oil in the microwave or over a double boiler.
Pour the melted chocolate over the peanut butter layer, spreading it evenly to coat.
Place the mold in the freezer for about 45 minutes until the bars are firm.
Once set, remove from the freezer and cut into bars.
To prevent the chocolate layer from cracking when cutting, run your knife under hot water before each slice. Cut gently!
