Begin by placing the freeze-dried strawberries in a food processor. Pulse until they transform into a fine powder.

In a bowl, combine the strawberry powder and powdered sugar, stirring until the mixture is evenly colored. Transfer this blend into a 1-gallon freezer bag and seal tightly.

Melt the white chocolate chips in the microwave using 30-second intervals, stirring until smooth.

In a large bowl, gently fold the melted chocolate into the Chex cereal until every piece is coated. Pour the mixture into the freezer bag and toss gently.

Spread the chocolate-covered cereal mix onto a baking sheet. Chill in the refrigerator for about 15 minutes to let the chocolate set, then store in an airtight container.
