Preheat oven to 350 degrees Fahrenheit. Mix one box of brownie mix (I used Betty Crocker), one egg, 1/4 cup water, and 1/4 cup oil.

Mix them together well until it's creamy.

Place evenly in a 13x9 inch pan

Place the 3 XL Kit Kat bars over the layer of brownie mix.

Mix the second box of brownie mix, 1 egg, 1/4 cup oil, and 1/4 cup water.

After mixed well, pour over the layer of Kit Kats.

Spread the batter out so it covers all of the Kit Kats.

Put in the oven for about 30 minutes at 350 Fahrenheit.

Let cool, then serve. I forgot to take a picture of the finished product because they were eaten quickly! Hope you enjoy! :)
