Preheat oven to 375 degrees. Line a 12-cup muffin pan with muffin cups.
Combine all ingredients except the chocolate chips in a food processor. Pulse until blended and mostly smooth (some chunks are okay!).
Stir in the chocolate chips. Spoon evenly into the muffin cups.
Bake for 17 minutes, or until muffins are lightly browned and a toothpick placed in the center of a muffin comes out clean.
