I first had this cake about 15 years ago. My good friends mom owned a catering wagon and had this cake on her menu. Years later, my aunt passed on her version of the recipe, basically all the ingredients are the same except hers increases the pancake mix and an extra egg. I found her recipe to be a little lighter/fluffier than my old recipe. I'm not sure were this recipe originated from, it was also passed on along to her.
I've heard of people adding orange zest and substituting orange juice for the milk. I haven't tried it myself, but heard it works well. I normally bake this cake in a bundt mold, and drizzle my cake while its still warm with condensed milk. My family loves this cake warm with a big glass of milk, let me tell you this hits the spot every time!
Pancake Mix Cake
2 1/2 c. complete pancake mix ( I use Krusteaz complete buttermilk pancake mix, I have used generic brands before and worked well)
1 c. sugar
5 whole eggs
1 c. oil
1 c. milk
Mix all ingredients with a mixer about 2 to 3 minutes. Pour into a greased and floured bundt cake mold and bake at 350 degrees for 35 to 45 minutes.
Test with wooden skewer for doneness.
Drizzle with condensed milk while still warm, slice and serve.
