Preheat oven to 350⁰F. Lightly grease 6 four-inch ramekins with non-stick cooking spray. Set aside.
In a medium bowl, stir crust mix from package and melted butter together with a fork until crumbly.
Divide 2/3 of crust evenly between ramekins and lightly press down with fork. Bake 15-18 minutes.
Remove ramekins from oven and spread raspberry filling from package evenly on top of crust. Sprinkle 1 cup white chocolate chips over raspberry filling. Top with remaining crust.
Bake 23-25 minutes, or until tops are golden and mixture is bubbly.
Remove from oven and let cool for at least 10 minutes.
While crumble is cooling, melt 1/4 cup white chocolate chips over medium power in the microwave, stirring every 15 seconds so not to burn. Drizzle melted chocolate over tops of crumble.
