Peel 3 ripe bananas, slice them into coins, and freeze on a parchment-lined baking sheet for at least 4 hours or overnight.

Remove the frozen banana slices from the freezer and let them sit at room temperature for 5 minutes to soften slightly.

Add the frozen banana slices to a food processor or high-speed blender.

Process for 1-2 minutes. The bananas will first look crumbly, then start to clump together.

Keep processing, scraping down the sides as needed, until the mixture transforms into a smooth, creamy consistency (about 3-4 minutes total).

Pulse in 3 tablespoons peanut butter.

Optional: Add 2 tablespoons of sugar-free chocolate chips or a sprinkle of cinnamon and pulse briefly to incorporate.

Serve immediately for soft-serve consistency, or transfer to a freezer-safe container and freeze for 1-2 hours for a firmer texture.

If frozen solid, let sit at room temperature for 5-10 minutes before scooping.
