Insert wooden sticks into the top of each apple, about halfway through.
Melt white chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between each until smooth.
Dip each apple into melted chocolate, turning to coat evenly.
Let excess chocolate drip off, then roll or sprinkle with crushed strawberries and cookies.
Place coated apples on a parchment-lined baking sheet.
Lightly dust with powdered sugar for a finishing touch.
Refrigerate 30 minutes until chocolate is set before serving.
