Add coffee, Milk, PBfit, and sweetener into a blender and blend on high speed for 2 minutes.
Prepare chocolate cold foam: Put heavy cream, milk, and chocolate sauce into a French press. Stir to combine. Chocolate sauce is thick, so mix the ingredients together.
Place the lid and move the plunger up and down 40 times.
The cold foam will increase in volume.
Fill a large glass with ice, pour over the PBFit Cold Brew, and then top with the chocolate cold foam.
