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

Cream together the softened unsalted butter, granulated sugar, and brown sugar until light and fluffy.

Add eggs one at a time, mixing well, followed by vanilla extract until smooth.

Gradually mix in the all-purpose flour until just combined to form a thick dough.

Gently fold in the crushed Fruity Pebbles cereal until evenly distributed.

Using a cookie scoop, portion mounds of dough onto prepared baking sheets, spacing 2 inches apart. Bake for 10-12 minutes until edges are golden but centers are soft.

Let cool on baking sheets before transferring to a wire rack. Frost and sprinkle additional Fruity Pebbles on top before serving.
