Step-by-Step Instructions

• Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
• In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
• In a large mixing bowl, cream together the unsalted butter, granulated sugar, and brown sugar until light and fluffy.
• Add the egg and vanilla extract to the butter-sugar mixture, mixing until well combined.
• Slowly incorporate the dry flour mixture into the wet ingredients until just combined.
• Heat the heavy cream in a small saucepan until bubbling. Remove from heat and whisk in the cornstarch until smooth.
• Fold the cream mixture into the cookie dough until well combined.
• Drop dollops of cookie dough onto the prepared baking sheet, spacing them 2 inches apart.
• Bake in the preheated oven for 10-12 minutes until edges are lightly golden and centers are soft.
• Cool the cookies on the baking sheet for 5 minutes before transferring to a wire rack.
• Sprinkle sugar on top of each cooled cookie, then caramelize using a kitchen torch.
• Allow the caramelized sugar to cool before serving.
