Peanut butter banana frozen dessert

I cook with an eight and a half year old. This dessert has two ingredients:
Equal parts ripe bananas & peanut butter

I had one ripe banana in the freezer and an almost ripe banana on the counter. So we heated the ripe banana and combined it with the fresh one and mashed them with a potato masher.

Then we took the banana and the peanut butter and placed it all in the blender with just a splash of water to lubricate it.

It tasted how I remember the filling in a "funny bone" cupcake to taste.

We put it in the ice cream machine and since it took forever to get the sticky mess out of the blender we ended up with a thick layer that was just like peanut butter ripple in commercial ice cream and a creamier filling on top.

I got it all out and mixed it well before I transferred it to the freezer.
