Ingredients
  

Graham cracker crust
  • 2 cup graham crackers Crushed into fine crumbs for even pressing.
  • 0.5 cup butter Melted; use salted or unsalted.
  • 3 tbsp brown sugar Add warm sweetness to the crust.
Ice cream filling
  • 0.5 gallon butter pecan or vanilla ice cream Soften until spreadable, not melted.
  • 0.5 cup butterscotch sauce Use for the ice cream layer; reserve extra for drizzling.
  • 1 tsp butter flavoring Helps mimic Butterbeer flavor.
  • 0.5 tsp vanilla extract Rounds out the sweetness.
Butterbeer cream topping
  • 2 cup heavy cream Chilled for best whipping.
  • 3 tbsp butterscotch sauce Whipped into the topping for a caramel color.
  • 2 tbsp powdered sugar Stabilizes the whipped cream.
  • 0.5 tsp butter extract Adds the buttery aroma and finish.

Equipment

  • 1 sheet pan
  • 1 springform pan

Method
 

Make the graham cracker crust
  1. Combine crushed graham crackers, melted butter, and brown sugar until evenly moistened, then press firmly into a 10-inch springform pan for a compact layer.
  2. Bake at 350°F for 8 minutes on a sheet pan, then cool completely until set and no longer warm to the touch.
Assemble the ice cream layer
  1. Fold butterscotch sauce, butter flavoring, and vanilla extract into the softened ice cream until smooth and evenly colored.
  2. Spread the butterscotch ice cream over the cooled crust and smooth the top with an even layer.
  3. Freeze for 6 hours until completely firm.
Top and finish
  1. Whip heavy cream with butterscotch sauce, powdered sugar, and butter extract to stiff peaks, then pile the topping dramatically high on the frozen cake.
  2. Drizzle extra butterscotch sauce in ribbons over the cream topping.
  3. Add any Harry Potter-themed decorations, then freeze for 2 more hours before releasing from the springform and serving.

Notes

For clean slices, run a thin knife under hot water and wipe between cuts; the crust stays crisp and the whipped topping keeps its shape. Refrigerate leftovers up to 3 days, but expect topping softening; freezing works well up to 2 months (freeze wrapped). For a lighter option, swap vanilla ice cream for a lower-fat or dairy-free ice cream that still whips and holds its structure.
