01 - Place the frozen banana slices into a high-powered blender or food processor.
02 - Blend on high, stopping to scrape down the sides as needed, until the mixture becomes completely creamy and smooth, about 1 to 2 minutes.
03 - Add vanilla extract or any other optional flavor additions such as cocoa powder or frozen berries, then blend again until fully combined.
04 - If a firmer, scoopable texture is desired, transfer the mixture to a freezer-safe container and freeze for 1 to 2 hours before serving.
05 - Scoop into bowls, add desired toppings such as chopped nuts, cacao nibs, or fresh fruit, and serve immediately.
