Line a 8x8 pan with parchment paper or use square silicone pan; set aside.

In the bowl of your food processor, process nuts, egg white protein, cacao powder and coffee powder until nuts have broken down into small pieces. Careful not to over-process, as the nuts will continue to break down in the next step.

Add in pitted dates and process until combined–the mixture will look a little dry. With the motor running about 1 tablespoon of water at a time until mixture is sticky and everything comes together. Depending on if your dates were juicy or dry, you may need less or more water. I used 6 tablespoons.

Once mixtures has come together and is sticky, remove S-blade and stir in cacao nibs if using.

Transfer mixture to lined 8x8 pan. Use slightly wet hands to press evenly into pan. I use his fun little pastry roller to make it extra flat.

Place pan in fridge for 1 hour, or freezer for 30 minutes before cutting into bars. Use large sharp knife and cutting board, cutting bars into 12 or 16 squares.
