Bake cake according to directions in a 9 X 13 pan
Let cake cool for about 5 minutes.
While cake is cooling, make the nougat filling. Melt butter in a saucepan over medium heat. Add sugar and milk stirring constantly until sugar is dissolved. Bring to a boil and stir for 4 minutes. Remove from stove and stir in marshmallow cream and vanilla. Mix until smooth
Poke holes in cake with the handle end of a wooden spoon.
Evenly our and distribute *nougat filling into the holes in the cake.
Next evenly pour and distribute caramel topping into the holes in the cake.
Let cake cool completely.
Once cake is cooled completely, evenly spread thawed cool whip over the top of cake.
Sprinkle chopped Milky Ways ( I also used snickers) over the top of cool whip.
Store in the refrigerator until ready to eat.
