Here's a recipe I've been promising Stacey I would put on the blog.  So, here it is!  Enjoy!

Sour Cream Chocolate Pound Cake
3 cups sugar
1 cup butter
¼ teaspoon baking soda
1 teaspoon vanilla
6 eggs
3 cups plain flour
¼ teaspoon salt
½ cup cocoa
1 cup sour cream

Cream butter and sugar until fluffy.
Add soda and vanilla.
Mix flour and salt.  Add in corn starch if altitude adjustment needs to be made.  
Then, alternate adding eggs one at a time with small amounts of flour mixture until all added.
Add cocoa and then sour cream. Mix until just blended. Bake at 325 for 1 hour 30 minutes (or until toothpick comes out clean) in a greased and floured tube pan.
