Grapes, bananas, strawberries, pretzels, or carrot sticks for serving (optional)

In bowl of food processor fitted with S-curve steel blade attachment, pulse together black beans, cocoa powder, maple syrup, grapeseed oil, water, vanilla extract, and salt until coarsely combined. Scrape down sides of food processor bowl with rubber spatula. Continue to blend until everything is thoroughly combined and smooth, pausing as needed to scrape down sides of bowl, about 2 to 3 minutes. Adjust consistency of dip to your liking by adding water a tablespoon at a time.

Scrape into serving bowl and garnish with grated dark chocolate, if using. Serve alongside your desired dippers and enjoy. If not planning to enjoy immediately, dip will keep nicely in airtight container in the refrigerator for 1 week.

Makes about 2 cups.
