BAKING TIPS
- Buttermilk Substitute: If you don’t have buttermilk, you can replace it with ½ cup milk with ½ tablespoon vinegar or lemon juice. You can use white vinegar or apple cider vinegar. Let the milk mixture sit for 15-20 minutes then use in the recipe as usual.
- Prepare: Bring all refrigerated ingredients to room temperature before starting to prepare your cake. Starting with room temperature eggs and milk will help them generate more air and also help the cake cook evenly.
- Cake Batter: Use a whisk to combine the ingredients to create more air as you are combining the ingredients. As you add the egg mixture, keep whisking quickly and add in a thin stream so that they don’t cook as you stir them in.
- Serve: Top a slice of warm cake with Vanilla Ice Cream or Whipped Cream for a delicious sweet cream and chocolate flavor combo. A drizzle of Salted Caramel Sauce would taste delicious too.

VARIATIONS
- Buttermilk: You can swap the buttermilk with sour cream or Greek yogurt for the same tangy flavor that also helps the cake stay tender and moist.
- 7Up Cake: Make a 7-up Sheet Cake by adding 7-Up soda instead of cola and making the cake a vanilla cake. Replace the cocoa powder with an extra ¼ cup all-purpose flour and increase to 1 tablespoon vanilla extract.
- Dr. Pepper Cake: A Dr. Pepper Chocolate Cake tastes even better with more a little cherry flavor added too. Add 1 tablespoon maraschino cherry juice and top frosting with chopped maraschino or candied cherries.
- Coca Cola Cupcakes: To make cupcakes, bake in well-greased muffin tins for 18-22 minutes until toothpick inserted comes out with moist crumbs. This batter should make about 24-30 cupcakes. Let the cupcakes cool completely before frosting.
- Round Cake Pans: Divide cake batter between 2 round pans sprayed with baking spray and lined with parchment circles in the bottom of the pan. Bake for 30-35 minutes, or until an inserted toothpick in center comes out with moist crumbs. Rest cakes for 15 minutes before removing from pan and allow to cool completely before layering and frosting.
