01 - Beat the softened butter and cream cheese in a large bowl with an electric mixer until smooth and creamy, about 2 minutes.
02 - Add the granulated sugar and beat until the mixture becomes light and fluffy, scraping down the sides of the bowl as needed.
03 - Mix in the egg and vanilla extract until well combined.
04 - Whisk together the all-purpose flour, baking powder, and salt in a separate bowl. Gradually add the dry mixture to the wet ingredients, mixing until just combined.
05 - Cover the dough and refrigerate for at least 30 minutes until firm.
06 - Preheat the oven to 350°F and line two baking sheets with parchment paper.
07 - Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
08 - Use the back of a spoon to gently press an indent into the center of each cookie dough mound.
09 - Dollop about 1/2 teaspoon of slightly cooled caramel sauce into each indent and swirl gently with a knife or toothpick.
10 - Bake for 11 to 13 minutes, or until the edges are lightly golden.
11 - Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
