Mix the protein powder(s), tahini, milk and agave. You may want to keep a sprinkling of the powder in reserve (as you’ll be adding the date syrup to half of the mixture and don’t want it to get too sticky).
Separate the dough in half, and to one half add the date syrup and coffee granules.
Roll out the dough into ‘sausages’ of each variety, and layer up to make a checkerboard pattern.
Chill, slice and devour :) These are even better kept in the freezer and enjoyed with a steaming cup of coffee!
