Prepare a 9x9 pan by spray lightly with cooking spray and place a piece of parchment paper in the pan with extra hanging out so you can pull it out of the pan.
Over a double boiler or in the microwave, melt your white chocolate chips.
When chips are melted, remove from heat and stir in your strawberry frosting, evenly.
Spread in your prepared pan and place in fridge to set for 30 minutes. Cut into squares to serve.
