Preheat the oven to 350 degrees and grease an 8"cast iron skillet
In a large mixing bowl place the ground flaxseed in with 3 tbsp of water and allow to gel for 3-5 minutes
Add in the butter and sugar and mix until well combined
Add in all other ingredients except for marshmallows, strawberries, and white chocolate and stir until well combined
Fold in the white chocolate, strawberries, and marshmallows, and spread evenly in the cast iron skillet
Bake for 25-30 minutes until the top is golden brown and the middles starts to set. Allow to cool for 15-20 minutes if you want the middle to set more or eat it warm
While the pizookie bakes place sliced strawberries in a microwave safe bowl and microwave for about two minutes until soften. Use a fork to mash the strawberries to create more of a jam texture
Optional to add a dash of maple syrup to the strawberries. Once ready to eat the pizookie add ice cream and strawberry compote on top.
