Ingredients

  • 3 squares unsweetened baking chocolate
  • 1/2 cup butter
  • 2 1/4 cups brown sugar
  • 3 eggs
  • 2 teaspoons vanilla extract
  • 2 1/4 cups cake flour
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 cup sour cream
  • 1 cup boiling water

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line with waxed paper.
  2. In a metal bowl over hot (but not boiling) water, slowly melt the unsweetened baking chocolate, stirring gently. Let cool.
  3. In a large mixing bowl, cream butter until smooth. Add brown sugar and eggs, beating at high speed for five minutes until light and fluffy.
  4. Beat in vanilla extract and cooled melted chocolate.
  5. Sift together cake flour, baking soda, and salt.
  6. Gradually mix the dry ingredients into the creamed mixture, alternating with sour cream, beginning and ending with dry ingredients.
  7. Stir in boiling water until the batter is thin.
  8. Pour the batter immediately into the prepared pans.
  9. Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
  10. Cool in pans for 15 minutes, then turn out onto wire racks to cool completely.

Tips & Substitutions

To enhance the chocolate flavor, consider adding a teaspoon of espresso powder to the batter. If you don't have sour cream, plain yogurt works as a great substitute. For a richer taste, use dark chocolate instead of unsweetened baking chocolate. Make sure not to overmix the batter after adding the flour to keep the cake light and fluffy.

Serving Suggestions

Serve the Classic Chocolate Fudge Cake with a dollop of whipped cream and fresh berries for an elegant touch. It pairs beautifully with a scoop of vanilla ice cream or a drizzle of chocolate sauce. Consider serving alongside a light salad or fruit platter to balance the richness of the cake.

Storage & Reheating

Store any leftover cake in an airtight container at room temperature for up to three days. For longer storage, refrigerate for up to a week. To reheat, place slices in the microwave for 10-15 seconds or in a preheated oven at 350°F (175°C) for a few minutes until warmed through.

Frequently Asked Questions

Can I use cocoa powder instead of baking chocolate?

Yes, you can substitute cocoa powder for unsweetened baking chocolate. Use 3 tablespoons of cocoa powder plus 1 tablespoon of vegetable oil for each square of chocolate. This will help mimic the fat content and maintain the chocolate flavor in the cake.

What should I do if my cake sinks in the middle?

If your cake sinks in the middle, it may be due to underbaking or too much leavening. Ensure you measure ingredients accurately and avoid opening the oven door too early while baking. A toothpick should come out clean when the cake is fully baked.

Can I make this cake ahead of time?

Absolutely! You can bake the cake a day in advance. Allow it to cool completely before wrapping it tightly in plastic wrap. Store it at room temperature, and frost it just before serving for the best texture and flavor.
