In a large bowl, stir together the protein powder, coconut flour, tahini, honey, almond milk, and peppermint extract until thoroughly mixed. Fold in the chocolate chips.
On a piece of parchment or wax paper, shape the dough into a rectangle. Feel free to adjust rectangle to size preference, mine was about 7 by 4.5 inches.
Place shaped dough into freezer for 15-20 minutes or until firm, but not totally set.
Slice the firm dough into 4 bars. Wrap bars in plastic wrap, bags, or store in an airtight container. Keep frozen and thaw just slightly before enjoying!
