Add all ingredients into your food processor, or high-speed blender and blend or pulse just until smooth. Often, I'll need to stop the blender to scrape down the sides a few times until everything is nicely combined.
Fill a silicone cupcake mold with your "nice" cream mixture, then top each cup with fresh banana slices, as shown if desired.
Freeze for about 4 hours or overnight.
Remove from molds and enjoy immediately, or wrap in plastic and store in your freezer for up to a week!
