Preheat your oven to 350°F (175°C) and prepare your baking sheets by lining them with parchment paper.

In a large mixing bowl, combine the softened unsalted butter, granulated sugar, and brown sugar. Beat on medium speed for 3-5 minutes until light and fluffy.

Add the egg and vanilla extract to the creamed mixture. Mix on low speed until thoroughly combined and smooth.

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing until just combined.

Gently fold in the strawberry jam, crushed strawberry-flavored cereal, and white chocolate chips into the cookie dough.

Using a cookie scoop or tablespoon, drop heaping spoonfuls of cookie dough onto the prepared baking sheets, spaced about 2 inches apart.

Bake for 10-12 minutes until edges are golden brown while centers remain slightly soft.

Cool the cookies on the baking sheets for about 5 minutes before transferring them to a wire rack.
