Freeze the bananas
Peel ripe bananas, slice them, and freeze until solid. This usually takes a few hours, but overnight is even better. Pro tip: slice first unless you enjoy wrestling frozen bananas like a caveman.
Add everything to the blender
Toss the frozen banana slices into a high-speed blender or food processor. Add a splash of milk and the vanilla extract.
Blend until creamy
Start slow, then increase speed. Stop to scrape down the sides as needed. At first it’ll look crumbly—don’t panic. Keep blending and it will magically turn smooth.
Adjust texture if needed
Too thick? Add a tiny splash more milk. Too soft? You blended too long—still delicious, just more “soft serve” vibes.
Serve immediately or freeze briefly
Eat right away for soft-serve texture, or freeze for 30–60 minutes if you want it firmer.
