Chocolate Chocolate Chip Sour Cream Pound Cake

After I couldn't find a recipe for chocolate sour cream pound cake, I made this recipe by combining three cake recipes and using some suggestions from my brother-in-law. It will stay moist for a week, but this cake is so good it won't last that long!

Before you begin, bring all of the cold ingredients to room temperature: set out the sour cream, butter, and the eggs (separate the eggs while they are still cold) for about half an hour before...

Ingredients

• 2 3/4 cups all-purpose flour
• 1/4 teaspoon baking soda
• 1/4 teaspoon salt
• 2 tablespoons unsweetened cocoa powder
• 1 cup sour cream
• 2 teaspoons vanilla extract
• 1 cup unsalted butter
• 2 1/2 cups white sugar, divided
• 6 eggs, separated
• 1/4 teaspoon cream of tartar
• 1/2 cup semisweet chocolate chips
