Step 1: Line two baking sheets with parchment paper. Set aside.
Step 2: In a stand mixer, combine the butter, sugar, vanilla, and egg. Beat on medium speed for 3 minutes, until fluffy. Add the flour, baking soda, salt, and cornstarch; beat until just combined.
Step 3: Pulse the Froot Loops in a food processor until crumbled. Remove 1 cup of crumbles, then continue pulsing the remaining pieces until very finely ground and powdery.
Step 4: Fold the crumbled pieces into the dough and stir to combine. Pour the Froot Loops powder into a small bowl.
Step 5: Form the dough into 15 balls, then roll each ball in the Froot Loops powder. Place on the baking sheets and refrigerate for at least 1 hour, or overnight.
Step 6: Preheat oven to 350°F. Bake cookies for 11 minutes, until they are puffy and just barely golden. Let cool for 30 minutes, then serve.
