Step 1

Place the strawberry cake mix in a microwave-safe bowl and microwave in 30-second intervals until the center of the cake mix reads 165°F on an instant-read thermometer. This kills any bacteria in the raw flour, making the cake mix safe to consume without being baked.

Step 2

In a large microwave-safe bowl, melt the white chocolate chips in 30-second intervals.

Step 3

Step 4

Pour the mixture into an 8x8-inch baking pan that is lined with aluminum foil.

Step 5

Evenly add sprinkles over top.

Step 6

Chill for 1 hour or until fudge is set.
