I have the Cake Doctor Cookbook (can't find it right now, so someone might have "borrowed" it. LOL) A lot of great recipes in there though.
I've also never heard of the milk/extra egg thing. But my grandmother's cakes/cupcakes were always SOOOO moist and delish. Her secret????
Instead of using water, she used 7-UP instead!!! Always made it so light and moist. MMMMM
Went to a get together at my friends about a month or so ago. I knew she had cake and I was all excited (I LOOOOOVE frosting) and I just couldn't wait to have a piece.

So anyhow, after we had a cookout, she brings the cake out and immediately I got all sad. It was one of those bundt type cakes that you just dust with powdered sugar.

I think I cried a little. LOL I was in the mood for a nice slice of chocolate cake with FROSTING!!!! But let me tell you.....it was sooooooo moist & sooooooo delicious that it didn't need a speck of frosting on it.
I believe it came from the Cake Doctor because when she told me the recipe I kind of remembered reading it in there. Hold on.....let me see if I can find it. Yep, here we go. Now, I'm not saying this is the most healthy of options but boooooyyyyyy, is it good.
Ingredients
1 (18.25 ounce) package devil's food cake mix
1 (3.9 ounce) package instant chocolate pudding mix
1 cup sour cream
1 cup milk
1/2 cup vegetable oil
1/2 cup water
4 eggs
2 cups semisweet chocolate chips
6 tablespoons butter
1 cup semisweet chocolate chips
Directions
1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 10 inch Bundt pan.
2. In a large bowl, combine cake mix, pudding mix, sour cream, milk, oil, water and eggs. Beat for 4 minutes, then mix in 2 cups chocolate chips.
3. Pour batter into prepared pan. Bake in the preheated oven for 40 to 50 minutes, or until a toothpick inserted into the center of the cake comes out clean. Cool 10 minutes in the pan, then turn out onto a wire rack and cool completely.
4. To make the glaze: Melt the butter and 1 cup chocolate chips in a double boiler or microwave oven. Stir until smooth and drizzle over cake.
