Place parchment paper in a 9x5 inch loaf pan.
Prepare base layer: add peanut butter, maple syrup, almond flour, vanilla extract, and salt to a mixing bowl. Stir together until combined.
Press base layer into bread pan with spatula.
Prepare chocolate layer: Add chocolate chips, peanut butter, and coconut oil to a microwave safe bowl. Heat for 15 to 30 second intervals, mixing in between, until chocolate is melted.
Pour chocolate layer over the base layer and spread evenly. Place in the fridge for 3 hours, or until both layers are firm.
Take out of bread pan and slice evenly into 12-14 bars. Top with flaky sea salt before serving. Store in the fridge or freezer.
