Step 1

Mix together the cake mix and powdered sugar in a large bowl.

Step 2

Add milk and butter (do not stir them in) and microwave for 2 minutes. It's cool cause the butter starts to "cook" with the batter, my kids loved looking at it.

Mixing everything together RIGHT away. The batter will be VERY thick.

Step 4

Fold in white chocolate until MOSTLY melted (a few chunks left is actually really nice in the fudge.

Cut into squares and enjoy
