Whisk together cream, milk, sugar, and 1 tsp maple extract until smooth. Pour into your ice cream machine and churn until the texture of soft serve, approximately 20 minutes.
In a separate bowl, whisk together the waffle mix, water, and remaining teaspoon of maple extract.
Cook the waffle batter in the waffle iron according to directions for your iron, usually 4-5 minutes.
When the waffle has cooled slightly, tear or slice into just smaller than bite-sized pieces. Chop the banana.
When the ice cream is finished churning, layer it into a freezer-safe container, a few cups at a time. Between each layer, scoop small spoonfuls of peanut butter, banana pieces, and waffle pieces onto the ice cream, and sprinkle a pinch of salt.
When all of the ice cream and toppings have been layered into the container, slowly swirl a knife or chopstick through the ice cream to distribute the swirls of peanut butter, banana, and waffle.
Freeze for at least 2 hours, serve, and enjoy!
