Potato Chip-Chocolate Toffee

• 2 sticks unsalted butter, plus more for the baking sheet
• 5 cups thick-cut potato chips
• 1 cup sugar
• 2 teaspoons vanilla extract
• 2 tablespoons apple cider vinegar or white vinegar
• 5 ounces bittersweet or semisweet chocolate, finely chopped

1. Line a baking sheet with foil and butter the foil.
2. Set 1 cup potato chips aside; break the remaining 4 cups chips in half if they're large.
3. Combine the butter, sugar, vanilla and vinegar in a saucepan over medium-high heat and cook, stirring occasionally, until the mixture is light amber and a candy thermometer registers 320 degrees F, about 10 minutes.
4. Remove from the heat and stir in the 4 cups chips, then immediately pour onto the baking sheet and spread in a thin layer.
5. Gently press the reserved 1 cup chips on top of the toffee and let cool.
6. Put about three-quarters of the chocolate in a microwave-safe glass bowl and microwave 30 seconds.
7. Stir, then continue to microwave in 30-second intervals, stirring between each, until melted.
8. Add the remaining chocolate and stir until smooth, about 4 minutes.
9. Drizzle the chocolate over the toffee.
10. Set aside to harden, about 20 minutes.
11. Break the toffee into pieces.
