Place the banana chunks in a blender or food processor. Blend until the mixture starts to get creamy, scraping down the sides as necessary. Add pecans and pulse until completely combined.
Serve immediately with a soft-serve consistency or place in a freezer safe container and freeze to serve later.
If you decide to leave it in the freezer, just allow it to sit at room temperature for 10 minutes or so, to soften before serving.
Enjoy!
Notes
The more ripe your bananas are the sweeter the nice cream will be.You can cut bananas into coins and freeze flat on a baking sheet for easier blending.If you have whole frozen bananas, you can break them into chunks before blending.
