Preheat oven to 350°F. Line an 8-inch square pan with parchment, leaving overhang.
Warm the raspberry preserves in the microwave for 15–20 seconds until loosened; set aside.
Stir graham crumbs, sugar, and salt in a bowl. Pour in melted butter and mix until evenly moistened.
Press the crumb mixture firmly into the lined pan to form an even crust.
Bake the crust for 7–8 minutes until set. Cool 5 minutes on a rack.
Stir vanilla into the sweetened condensed milk.
Drizzle half the condensed milk over the crust. Sprinkle on semisweet chips, white chips, coconut, nuts, and crushed raspberries.
Dot the surface with spoonfuls of raspberry preserves, then drizzle on the remaining condensed milk.
Bake 22–24 minutes until the edges are deeply golden and the center looks set but still gooey.
Cool completely. Chill 30 minutes for cleaner cuts, then lift out and slice into 16 bars.
