In a large mixing bowl, whisk together the vanilla protein powder, almond flour, and sea salt.
Add the almond butter, maple syrup, and vanilla extract to the dry mixture.
Stir the ingredients until a thick and crumbly dough begins to form.
Add the almond milk one tablespoon at a time, mixing between additions until the dough becomes cohesive and pliable.
Fold in the mini chocolate chips until evenly distributed.
Line an 8x4 inch loaf pan with parchment paper, leaving an overhang on the sides for easy removal.
Transfer the dough to the prepared pan and press down firmly to create an even, level surface.
Place the pan in the refrigerator for a minimum of 60 minutes to allow the bars to firm up.
Lift the parchment paper to remove the slab from the pan and cut into 8 rectangular bars.
