Ingredients

• 1 pint vanilla ice cream (not gelato), melted
• 4 (1–1 1/2"-thick) slices challah or brioche
• 5 tablespoons unsalted butter, divided

Instructions

1. Preheat oven to 250°F. Pour ice cream into a large baking dish. Add bread, turn to coat, then let sit 3 minutes. Flip bread and continue to soak until saturated but not soggy, about 3 minutes more.
2. Heat 2 Tbsp. butter in a large skillet over medium. Using tongs, carefully lift 2 bread slices from custard, letting excess drip back into dish. Transfer to skillet in a single layer and cook until golden brown and the center of toast springs back when pressed, about 4 minutes per side. Transfer to a wire rack set inside a rimmed baking sheet; keep warm in oven until ready to serve. Repeat with 2 Tbsp. butter and remaining bread. Top toasts with remaining 1 Tbsp. butter and serve.
