In a food processor fitted with the chopping blade, pulse together walnuts, almonds, oats, and PB2 Powder until finely ground. Add dates and process mixture until dates are broken down and mixture starts to stick together. Set aside and clean out the bowl and blade of the food processor.

Place bananas, dates, cocoa powder, vanilla and salt in the bowl of the food processor and pulse about 15 times or until the bananas are broken down.

Process the mixture for about 45 seconds until it resembles soft serve ice cream.

Lightly spray a 4" springform pan with cooking spray, and press ½ of the cookie/crumb mixture into the bottom and slightly up the sides of the pan.

Add banana ice cream.

Top with remaining crumb mixture and lightly press the crumbs into the top of the ice cream.

Freeze the ice cream sandwiches for 1-2 hours to firm up.

Slice and serve immediately.

If theses are frozen for several hours, or are too hard to slice, let them thaw for about 10 minutes.
