Preheat oven to 350 degrees and line with parchment paper or spray an 8×8 baking dish. You can also use a 9×5 loaf pan.
In a food processor (or high speed blender), add all ingredients except chocolate chips and process until batter is smooth, similar consistency to hummus.
Stir in 1/2 cup of the dark chocolate chips (reserving a few for the top).
Scoop the batter into the lined pan and smooth it out evenly. Lightly press the remaining chocolate chips over the top.
Bake for 30 minutes or until toothpick comes out clean if using an 8×8 pan or bake for 60 minutes if using a loaf pan. This will vary with ovens so be patient and wait until the edges are beginning to brown.
Cool for 10 minutes in the pan then transfer to a rack for another 30 minutes for them to set. The longer the better, I’d say a couple hours. (I know, it’s so hard to wait that long!)
Cut into squares and enjoy!
