Ingredients
  

Graham cracker crust
  • 2 cup graham crackers Crushed into fine crumbs.
  • 0.5 cup butter Melted.
  • 3 tbsp brown sugar Packed.
Ice cream filling
  • 0.5 gallon butter pecan or vanilla ice cream Softened.
  • 0.5 cup butterscotch sauce Plus extra for drizzling.
  • 1 tsp butter flavoring
  • 0.5 tsp vanilla extract
Butterbeer cream topping
  • 2 cup heavy cream Cold for best whipping.
  • 3 tbsp butterscotch sauce
  • 2 tbsp powdered sugar
  • 0.5 tsp butter extract

Equipment

  • 1 springform pan

Method
 

Make and bake the graham crust
  1. Combine the graham cracker crumbs, melted butter, and brown sugar until evenly moistened, then press firmly into a 10-inch springform pan to form an even layer. Bake at 350F for 8 minutes, then cool completely so the ice cream won’t melt on contact.
Assemble and freeze the ice cream layer
  1. Fold butterscotch sauce, butter flavoring, and vanilla extract into the softened ice cream until smooth, then spread the mixture over the cooled crust and smooth the top. Freeze for 6 hours until completely firm.
Whip the butterscotch cream topping
  1. Whip the heavy cream with butterscotch sauce, powdered sugar, and butter extract until it reaches stiff peaks. Pile the whipped topping dramatically high on top of the firm frozen cake.
Finish and freeze to set
  1. Drizzle extra butterscotch sauce in ribbons over the cream topping, then add any Harry Potter-themed decorations. Freeze for 2 more hours before releasing from the springform and serving.

Notes

For clean slices, run a thin knife around the edge after the final freeze and release the springform right before serving. Store covered in the freezer up to 2 weeks; freeze is yes—this cake holds shape well. For a dairy-free swap, use a dairy-free vanilla/butterscotch ice cream and coconut cream (chilled) while keeping the butterscotch sauce portion the same.
