I used this cake recipe about a year ago and it was very good. Unfortunately, it was in my favorites but somehow they have been lost. Does anyone have this recipe? It starts from a box cake mix and you add other ingredients. Please share :).....thanks

Not sure if this is the one you are looking for. 

1 box BC Triple Chocolate Fudge Cake (w/ mini choco chips)
1 box DH Dark Chocolate Fudge cake
1 1/2 cups flour
1/2 cup cocoa
2 cups sourcream
2 4oz pkg chocolate fudge instant pudding
8 eggs
1 cup veg oil
2 2/3 cup chocolate milk
2 tsp vanilla
1/2 cup mini choco chips

Sift dry ingrediants together and then add wet, mix until incorporated and then mix for 2 minutes. Bake at 325 until toothpick comes out clean. You may have to test a few times, sometimes I hit a choco chip and my toothpick comes out all messy.
You cant really half the recipe because the flavor comes from the combo of the 2 chocolate mixes so it makes a lot of cake.

I'm not sure if this is the one you had, but I found this on the Wilton site; it seems to account for the smaller-sized cake mixes:

Cake recipe:

1 box Betty Crocker triple chocolate fudge cake mix
1 small box Jell-o chocolate fudge instant pudding
1/4 cup cake flour
3 whole eggs
1/2 cup canola or veggie oil
1 1/3 cup water
2 t. good quality vanilla extract
1 t. butter flavoring

Mix all ingredients for 30 seconds on low, scrape down bowl, then beat on Speed 2 (medium) on KA stand mixer for two minutes.

Pour into two 8" round prepared pans using collars. Bake until done at 350 degrees.
 

Thank you so much for the help. I was frantic trying to find the recipe. Both will be helpful. Thanks again!
 

Thank you so much...This is the original that I used....
