Ingredients for Chocolate Fudge Cake

TASTE OF HOME

• Butter: Butter serves as the base for the cake batter and the frosting, playing a role in flavor and structure. For best results, use butter softened to room temperature.
• Brown sugar: This recipe relies on brown sugar for its deep molasses flavor and a touch of sweetness.
• Eggs: Three large eggs are added to the cake batter to provide moisture and help to make the cake rise.
• Vanilla extract: A small amount of vanilla extract goes a long way in enhancing the flavor of the chocolate in this cake recipe.
• Unsweetened chocolate: While there are many types of baking chocolate, this particular recipe makes good use of unsweetened chocolate in both the cake batter and the frosting. This allows for a deeper chocolate flavor, along with better control over sweetness.
• Cake flour: Cake flour is used to create a fine, tender crumb in homemade cakes. It has less protein in it, creating a softer texture. For best results, sift the cake flour before adding it to the batter.
• Baking soda and baking powder: Baking soda and baking powder are both leavening agents. They react with other ingredients in the batter to help the cake rise while baking.
• Salt: Just a touch of salt helps to cut the sweetness in the batter for the ideal flavor balance.
• Sour cream: Adding sour cream to a cake batter is a clever trick to make the cake that much more moist. If you don’t have sour cream, you could also use Greek yogurt or bake with mayonnaise.
• Water: Water is the liquid in this cake batter, providing moisture for proper texture.
• Confectioners’ sugar: The powdery consistency of confectioners’ sugar creates a fluffy, smooth frosting and also sweetens the mixture.
• Whole milk: The milk thins the frosting, allowing for easier spreadability.

Chocolate Fudge Cake Variations

• Top with chocolate ganache: This cake is topped with a smooth, creamy chocolate fudge frosting. If you’d like another option, consider ganache. Chocolate ganache is thicker for a more decadent choice, making it ideal for pairing with many chocolate dessert recipes.
• Add chocolate chips: Need even more chocolate? Consider adding chocolate chips to the finished cake batter before baking, or use them to dress up the exterior of the frosted cake.
• Top with peanut butter frosting: Love a chocolate and peanut butter combo? Skip the fudge frosting and make homemade peanut butter frosting instead.
