Drain the chickpeas into a glass measuring cup and reserve the can liquid (aquafaba).
To the bowl of a food processor, add the chickpeas, tahini, maple or agave syrup, cocoa powder, vanilla, kosher salt, and 2 tablespoons aquafaba. Puree for 30 seconds, then scrape down the bowl. Taste; if necessary, add a bit more syrup to sweeten the taste even further. Add additional 1 to 2 tablespoons aquafaba and puree again to come to a creamy consistency. Store refrigerated for 7 to 10 days.
Serve with pretzels, pineapple, green apple slices, and strawberries.
