1-Preheat your oven: preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. This step sets the stage for even baking and prevents sticking, which is crucial for gooey caramel cookies.

2-Cream the butter and sugars: In a large bowl, cream the butter, dark brown sugar, and granulated sugar together for 4 minutes until light and fluffy. Next, add the egg, egg yolk, and vanilla; mix for 1 minute to blend everything smoothly.

3-Stir in caramel sauce: Stir in the 1/4 cup of caramel sauce until it’s evenly combined, creating that rich caramel flavor we love. Then, fold in the flour, baking powder, baking soda, and salt mix just until a dough forms, being careful not to overdo it.

4-Chill and scoop the dough: Optional: Cover and chill the dough for 30 minutes up to 24 hours for a tighter cookie texture. Scoop the dough into balls, about 1-2 tablespoons each, and place them on the prepared baking sheet.

5-Bake the cookies: Bake for 8-11 minutes, or until the edges turn a light golden color. Once done, remove from the oven, let the cookies set on the sheet for 5 minutes, then transfer to a wire rack. While still warm, drizzle with additional caramel sauce and sprinkle sea-salt flakes if you want that sweet-salty finish.
