Place the garbanzo beans, peanut butter, vanilla extract, and maple syrup into a high-speed food processor. Blend on high for 1 to 2 minutes until smooth, scraping the sides as needed.
Add the oats, chocolate chips, and M&Ms to the food processor. Pulse until combined. If the batter is too thick, add water by the teaspoon.
Serve with a spoon or your favorite dipping vessels.
Notes
Avoid blending the chocolate chips and M&Ms in the food processor to prevent the color from bleeding into the dough and the M&Ms from breaking down.
