Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar until light and fluffy.

Add in the egg and vanilla extract to the creamed mixture and beat until fully combined.

Whisk together the all-purpose flour, baking soda, and salt in a separate bowl, then gradually add to the wet mixture until just combined.

Fold in the strawberry jam, crushed cereal, and white chocolate chips until evenly distributed.

Drop rounded tablespoon portions of dough onto prepared baking sheets, spacing them 2 inches apart.

Bake for 10-12 minutes, until the edges are lightly golden, then cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
