Line the bottom of a 9'' cake pan with parchment paper
In a large mixing bowl create the chia eggs (combine 3 tbsp chia seeds and 9 tbsp water and let sit 5 minutes)
Add the sugar, powered peanut butter, cocoa powder, and 4 tbsp water to chia eggs. Whisk to combine.
Pour 2/3 of the mixture in the parchment lined cake pan
Place in freezer (This layer must freeze at least 3 hours before layering in ice cream!)
Line baking sheet with silicon baking mat or parchment paper
Pour remaining fudge mixture on baking sheet and spread in a thin even layer about 1/8'' thick
Bake 15-20 min or until no longer tacky (It will become really dull in color. We're looking for crunchy not burnt so keep an eye on it!)
Move silicon mat to a wire rack to cool
After completely cool break into pieces and put into a ziplock bag, crush up with a mallet/wooden spoon/rolling pin into small pieces
Chocolate/Vanilla Ice Cream Layer
Line bottom of a spring form pan with parchment paper
Add 4 1/2 frozen bananas, 1 tbsp maple syrup, and 1/4 cup cocoa powder to a food processor and pulse until smooth
Pour chocolate mixture into pan and smooth into an even layer
Freeze at least 30 minutes before proceeding!
Add 4 1/2 frozen bananas and 1 tbsp maple syrup to a food processor and pulse until smooth
Take spring form pan and cake pan from freezer
Remove fudge layer from cake pan (this defrosts very quickly and is very sticky! handle carefully) flip upside down into spring form and slowly peel off the parchment
Take cookie crumbles and sprinkle over top of fudge layer
Pour vanilla ice cream mixture on top and smooth into an even layer
Freeze overnight (At least! I made mine 2 days ahead to make sure it was very solid all the way through.)
When you're ready to unveil your cake take a dish towel and dampen it with warm water. Wrap the dish towel around the spring form pan for about 30 seconds this helps the cake release from the sides of the pan. Say a prayer and open the spring. Remove cake from pan. Hold the cake and peel the parchment from the bottom and place on serving platter.
