Strain beans and add them to a food processor. Add the remaining ingredients and process with an S blade until smooth. Place in a bowl. Enjoy! If you want refrigerate for at least 1 hour. I like it better cold and it gets thicker... like frosting.
You could switch out the beans to another mild bean like chickpeas, but the consistency may be different. Black beans give it a smoother consistency.
Depending on the type of nut butter and the brand may yield different taste and consistency.
If the consistency seems to be too hard, you can thin it out with a little water. I would add a teaspoon at a time.
Placing the chocolate hummus in the fridge to chill will make it get slightly harder and will make it more of the consistency of frosting.
