Triple Chocolate Fudge Cake

I am behind on posting my recipes, but I did want to be sure to get this one up because it would be a yummy Valentine's dessert. My mom got the recipe from one of her good friends and made it for my sister's birthday dinner last week. It was SOOOO good (my favorite bites had the melty chocolate chips inside!), especially served warm with ice cream on the side!

1 chocolate cake mix (with pudding in the mix!)
1 large box chocolate pudding
1/2 c vegetable oil
1/2 c warm water
4 eggs
1 c sour cream
1 12oz package chocolate chips

Grease and flour a 12 cup bunt pan and preheat oven to 350 degrees.
Combine cake mix and pudding mix. Blend in oil, water, eggs, sour cream.
Stir in chocolate chips. Pour into pan.
Bake 45 min-1 hour.
Cool 10 min, then slide knife around edges of pan and invert.
Cool completely and glaze.

Melt 1/3 c margarine and stir in 2 cups powdered sugar. Blend in 1/2 t. vanilla.
*my mom's friend sometimes just heats up a tub of frosting from the store and pours over the top instead.
