Butterscotch-Cornflake Apple Crisp

Preheat the oven to 375°F. Line a rimmed baking sheet with foil. In a large bowl, toss the apples with the granulated sugar, lemon juice, cinnamon, and ¼ teaspoon salt. Scrape the apples and juices into a 2-quart baking dish.

In the same bowl, combine the flour, brown sugar, and remaining ¼ teaspoon salt. Add the butter and mash with your fingers until the butter is incorporated and crumbs form. Add the cornflakes and use your hands to fold the cornflakes into the mixture. Squeeze into clumps and sprinkle over the apples in the baking dish.

Place the baking dish on the prepared baking sheet and bake until the crisp is golden and bubbling, 55 to 60 minutes. (Cover loosely with foil for the last 15 minutes if the top is getting too brown.) Let cool about 10 minutes.

Meanwhile, make the butterscotch sauce: In a small saucepan, melt the butter over medium heat. Add the brown sugar, heavy cream, and vanilla and stir to combine. Bring to a boil and cook until thickened, about 5 minutes. Remove from the heat and let cool about 10 minutes.

Drizzle the apple crisp with some of the butterscotch sauce. Serve with ice cream and the remaining sauce.
