Turn a Box Cake Mix into a Sponge Cake!

Hey guys! I wanted to share with you this awesome way to turn a boxed cake mix into a delicious sponge cake! All you need to do is follow a few simple techniques and the cake mix will turn into the most Delicious light and fluffy sponge cake! It also slightly changes the flavor of the mix a bit to a more delicate vanilla flavor. The secret is also to always use butter instead of the oil to make the taste more pleasing.

Ingredients:
1 box cake mix any flavor
Melted butter (amount it says for the oil)
Water (amount stated on back of box)
eggs

Instructions:
1.First thing is to be sure to grease and flour the pans you are going to use. I used an 11-inch cake pan in the video but you can use a 13x9 or 2, 8-inch cake pans. Also be sure to preheat the oven to 350 so it will be ready when you are.
2. Sift the cake mix into the bowl and make sure to get rid of all the bumps from the flour. Add however much water the back of the box says and add melted butter instead of the amount of oil it says to use.
3. For the eggs, separate the whites to the side in a separate bowl and mix the cake mix with the yolks and remaining ingredients until it's all combined and smooth.
4. Whip the bowl of egg whites until they become stiff and slowly fold them into the cake mix.
5. Pour everything into the pan and bake until a toothpick inserted comes out clean.
