Prepare white cake mix according to box instructions. Pour batter into the prepared pan and bake for about 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool for 10 minutes and using the bottom of a wooden spoon, poke holes all over the cake.
Strawberry White Chocolate Mixture:
Stir in the strawberry gelatin mix into the warm water. Make sure it dissolves, otherwise it will be gritty. Stir the strawberry mixture into the condensed milk mixture until fully combined and smooth.
