Ingredients

  • 2 cups sugar
  • 2 cups flour
  • 1/2 cup shortening
  • 1 stick oleo
  • 1 cup water
  • 4 tablespoons cocoa
  • 1/2 cup buttermilk
  • 2 eggs
  • 1 teaspoon soda
  • 1 teaspoon vanilla

  1. Sift together the sugar and flour.
  2. In a saucepan, bring to a boil the shortening, water, and cocoa.
  3. Pour the hot mixture over the flour mixture.
  4. Add the buttermilk, beaten eggs, soda, and vanilla to the mixture.

Tips & Substitutions

For a richer flavor, use unsweetened cocoa powder and consider substituting half of the shortening with unsalted butter. If you don't have buttermilk, you can make a quick substitute by adding a tablespoon of vinegar or lemon juice to regular milk. Sifting the sugar and flour helps to create a lighter texture in the cake. To enhance the chocolate flavor, you might add a pinch of espresso powder to the batter.

Serving Suggestions

This chocolate cake is delicious on its own but can be elevated with a simple chocolate or cream cheese frosting. It pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream. For added texture, consider serving it with a side of Toffee Crunch for an interesting contrast. Enjoy it as a sweet finish to a meal or as a delightful treat with coffee or tea.

Storage & Reheating

Store any leftover chocolate cake in an airtight container at room temperature for up to three days. If you prefer, you can refrigerate it for longer freshness, but be sure to let it come to room temperature before serving. To reheat, simply warm individual slices in the microwave for about 10-15 seconds or enjoy it cold.

Frequently Asked Questions

Can I use a different type of flour for this recipe?

Yes, you can substitute all-purpose flour with whole wheat flour for a healthier option, though it may change the texture slightly. If using gluten-free flour, ensure it has a binding agent like xanthan gum to help the cake hold together.

What can I do if my cake is too dry?

If your cake turns out dry, it could be due to overbaking. To prevent this, check for doneness a few minutes before the suggested baking time. If it’s already baked, you can serve it with a drizzle of chocolate sauce or a scoop of ice cream to add moisture.

How can I make this cake more chocolatey?

To enhance the chocolate flavor, consider adding chocolate chips to the batter or using dark cocoa powder instead of regular cocoa. You can also layer the cake with a rich frosting or ganache to amplify the chocolate experience.
