Peel the ripe banana, slice it into coins, and place the slices on a parchment-lined tray. Freeze the banana slices for at least 2 hours or until completely frozen.
Once the banana slices are frozen, transfer them to a blender or food processor.
Add the peanut butter to the blender or food processor.
If the mixture is too thick to blend, add 1-2 tablespoons of plant-based milk to help it blend smoothly.
Blend the mixture until smooth and creamy, scraping down the sides of the blender or food processor as needed.
Once the mixture reaches a smooth consistency, transfer it to a bowl.
Serve immediately as soft-serve ice cream, or transfer it to a container and freeze it for 30-60 minutes for a firmer texture.
Before serving, you can sprinkle your favorite toppings such as chopped nuts, shredded coconut, or chocolate chips on top.
Enjoy your delicious dairy-free Peanut Butter Banana Ice Cream!
Note: You can adjust the amount of peanut butter according to your preference for a stronger or milder peanut butter flavor.
