01 - Place the frozen banana slices into a high-powered food processor or blender.
02 - Blend until the bananas break down into small crumbly pieces, then continue processing until a smooth, creamy mixture forms. Scrape down the sides of the bowl as needed to ensure even blending.
03 - Add any desired flavor additions such as cocoa powder, frozen berries, nut butter, vanilla extract, or salt. Blend again until all ingredients are fully incorporated and the mixture is homogeneous.
04 - Serve immediately for a soft-serve consistency, or transfer the mixture to a freezer-safe container and freeze for 1 to 2 hours for a firmer, scoopable texture.
05 - Top with fresh fruit, chopped nuts, dark chocolate shavings, or coconut flakes before serving.
