Chop Banana (2) and add to a food processor. Pulse 5-6 times, then let run for 10 seconds or until bananas are smooth and creamy.
Add in Unsweetened Cocoa Powder (1/4 cup), Ground Cinnamon (1/2 teaspoon), Cayenne Pepper (1/4 teaspoon), Vanilla Extract (1/2 teaspoon), and Maple Syrup (1 tablespoon) and blend until mixture is smooth and well combined.
Add in Dark Chocolate Chunks (1/4 cup) and pulse another 5-7 times, or until chocolate chunks are mixed in, but still in pieces for a crunch.
Add mixture to freezer-safe container and put in freezer for at least 30 minutes. The mixture is like a soft-serve ice cream after about 20 minutes but firms up like hard scoop ice cream after about 45 minutes to an hour.
