Preheat your oven to 350°F. Grease a 13x9 baking pan and line it with parchment paper, if desired. Set aside.
Put the 12 oz of gingersnap cookies into a food processor and pulse until you have a fine crumb. Mix gingersnap crumbs with 10 tablespoons of melted butter and a pinch of salt. Dump the mixture into the prepared pan, and press firmly into an even layer.
Sprinkle the other ingredients one layer at a time on top of the gingersnap crust. Start with the white chocolate chips, then cinnamon chips, coconut flakes, almonds, and pretzels, Lastly, pour the entire can of sweetened condensed milk evenly over top of everything.
Pop into the oven and bake for 25-28 minutes. Once done baking, remove from the oven and allow to cool completely before slicing! Enjoy!
