Place the bananas in a food processor and process. The bananas will begin to look like dry crumbs, not a creamy soft serve. This is good. You may have to stop and stir the fruit a few times as the bananas often form a clump. (see notes)
When you reach the “crumb” stage, add all the remaining ingredients except the honey or sweetener of choice. I gently mix the cocoa powder into the banana mixture, just enough so that it doesn’t poof up when you start the processor.
Enjoy immediately as you would soft serve ice cream or store in freezer. This will freeze hard like regular ice cream. When I make extra to store in the freezer, I let it sit at room temperature a few minutes to soften before serving.
