Stir together the peanut butter and honey until combined

Stir in the oats and vanilla protein powder until totally mixed. The batter should be thick but not too sticky.

Transfer the peanut butter batter to an 8 by 8 parchment paper lined baking dish. Flatten down the top and spread it evenly into the pan.

Melt the dark chocolate chips and semi sweet chocolate chips in the microwave in 30 second increments until smooth. Stir often to avoid burning.

Pour the melted chocolate over the top of the peanut butter layer and smooth it out using a rubber spatula

Sprinkle flaked sea salt over the top of the melted chocolate layer

Chill in the fridge until the chocolate is set, or 1-2 hours. The chocolate should be hardened completely

Cut the bars into 16 pieces and store in an airtight bag or container in the fridge or freezer
