Ingredients

For the Cake:

2 cups all-purpose flour

1/2 cup butter, softened

1 1/2 cups dark brown sugar

3 large eggs, at room temperature

1/4 cup unsweetened cocoa powder

1 cup strong black coffee, cooled

1 teaspoon vanilla extract

1 teaspoon baking soda

1/2 teaspoon salt

1 tablespoon white vinegar

For the Cream Cheese Frosting:

1/2 cup butter (1 stick or approximately 110 g), softened

8 ounces (approximately 220–227 g) cream cheese, softened

1 teaspoon pure vanilla extract

3–4 cups confectioners’ sugar, sifted

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and position the oven rack in the center. Grease two 8-inch round cake pans with butter and line the bottoms with parchment paper. Make sure the butter, eggs, and other refrigerated ingredients are at room temperature before beginning.
  2. Prepare the dry ingredients: In a medium mixing bowl, combine the all-purpose flour, cocoa powder, baking soda, and salt. Sift the mixture together 2–3 times to remove lumps and distribute the ingredients evenly. Set aside.
  3. Cream the butter and sugar: In a large mixing bowl, beat the softened butter and dark brown sugar with an electric mixer until smooth, creamy, and slightly fluffy.
  4. Add the eggs and vanilla: Beat in the eggs one at a time, mixing well after each addition. Add the vanilla extract and mix until fully incorporated.
  5. Begin combining the batter: Add approximately one-third of the sifted dry ingredients to the butter mixture and mix gently until just combined. Pour in 1/2 cup of the cooled strong black coffee and stir until incorporated.
  6. Add the remaining coffee: Add another third of the dry ingredients, mixing gently, followed by the remaining 1/2 cup of coffee. Stir until the batter is mostly smooth.
  7. Finish the cake batter: Stir in the white vinegar, then gently fold in the remaining dry ingredients until no visible streaks of flour remain. Avoid overmixing to maintain a soft, tender crumb.
  8. Fill the cake pans: Divide the cake batter evenly between the two prepared 8-inch round cake pans. Smooth the tops with a spatula to ensure even baking.
  9. Bake the cake: Place the pans in the preheated oven and bake for approximately 20–25 minutes, or until the tops are set and a toothpick inserted into the center comes out clean or with a few moist crumbs. Avoid overbaking.
  10. Cool the cake layers: Remove the pans from the oven and allow the cakes to cool in their pans for approximately 5 minutes. Carefully turn the layers onto a wire rack, remove the parchment paper, and allow them to cool completely before frosting.
  11. Prepare the cream cheese frosting: In a large mixing bowl, beat the softened butter with an electric mixer until light and fluffy. Add the softened cream cheese and continue beating until smooth and creamy.
  12. Sweeten the frosting: Mix in the pure vanilla extract and 1 cup of sifted confectioners’ sugar. Gradually add the remaining confectioners’ sugar, one cup at a time, until the frosting reaches your desired sweetness and spreading consistency. Use approximately 3 cups for a softer frosting or up to 4 cups for a firmer, sweeter frosting.
  13. Assemble the cake: Place one completely cooled cake layer on a serving plate or cake stand. Spread an even layer of cream cheese frosting over the top using an offset spatula.
  14. Frost the cake: Carefully place the second cake layer over the first. Spread the remaining cream cheese frosting evenly over the top and sides of the cake, smoothing or creating decorative swirls as desired.
  15. Set and serve: Refrigerate the frosted cake briefly if needed to help the frosting firm up. Slice into 6 generous portions and serve. For the best flavor and texture, allow refrigerated cake slices to stand at room temperature for approximately 20–30 minutes before enjoying.

Notes

Room temperature ingredients: Allow the butter, eggs, and cream cheese to reach room temperature before mixing. This helps create a smoother batter and creamier frosting. Do not leave cream cheese at room temperature for extended periods.

Strong coffee: Use freshly brewed strong black coffee or espresso-strength coffee for a deeper chocolate flavor. Allow the coffee to cool before adding it to the batter.

Instant coffee substitution: Dissolve instant coffee granules in hot water to prepare 1 cup of strong coffee. Cool before using.

Why vinegar is important: White vinegar reacts with baking soda to help the cake rise and develop a soft, tender texture. It also contributes to the traditional mahogany cake’s characteristic crumb.

Chocolate variation: Add a little extra cocoa powder for a stronger chocolate flavor. Adjust the liquid slightly if necessary to prevent the batter from becoming too thick.

Coffee lovers’ variation: Substitute espresso-strength coffee for regular brewed coffee to intensify the coffee notes.

Chocolate frosting: Replace the cream cheese frosting with chocolate buttercream for a richer chocolate dessert.

Nutty variation: Fold chopped walnuts or pecans into the finished cake batter for extra texture and a subtle nutty flavor.

Cupcake variation: Divide the batter among lined cupcake tins, filling each liner approximately two-thirds full. Begin checking for doneness after 15–18 minutes and adjust the baking time as needed.

Simple powdered sugar finish: Skip the cream cheese frosting and dust the completely cooled cake with confectioners’ sugar for a lighter presentation.

Different cake pans: The recipe is designed for two 8-inch round cake pans. Other pan sizes may be used, but baking times will vary depending on the depth and size of the pans.

Avoid overmixing: Mix the batter only until the dry ingredients are incorporated. Excessive mixing can develop gluten and produce a denser cake.

Keep the cake moist: Avoid overbaking and check the cake near the beginning of the recommended baking time. Store the finished cake properly covered to prevent drying.

Frosting consistency: If the cream cheese frosting becomes too soft or runny, refrigerate it for approximately 15–20 minutes before spreading. Avoid using excessively warm butter or cream cheese.

Frosting sweetness: Start with 3 cups of confectioners’ sugar and add more gradually until the desired sweetness and firmness are reached.

Cool before frosting: Make sure both cake layers are completely cool before applying the frosting. Warm cake layers can cause cream cheese frosting to melt and slide.

Make ahead: Bake the cake layers one day in advance. Allow them to cool completely, wrap tightly, and refrigerate until ready to frost.

Refrigeration: Store the frosted Mahogany Cake in an airtight cake container in the refrigerator for up to 4–5 days.

Freezing unfrosted layers: Wrap completely cooled cake layers tightly in plastic wrap and place them in freezer-safe bags or containers. Freeze for up to 3 months for best quality. Thaw before frosting.

Freezing leftover slices: Wrap individual cake slices securely and freeze in airtight containers. Thaw overnight in the refrigerator before serving.

Serving temperature: For the softest crumb and creamiest frosting, allow refrigerated cake slices to sit at room temperature for approximately 20–30 minutes before serving.

Reheating: Reheating frosted cake is not recommended because the cream cheese frosting may melt or separate.

Timing: The listed 45-minute total includes active preparation and baking but does not include complete cooling, frosting, or optional chilling. Allow additional time before serving.

Nutrition: Nutritional values are approximate per generous slice based on 6 servings, 3 1/2 cups of confectioners’ sugar, full-fat cream cheese, and the remaining listed ingredients. Actual values vary depending on ingredient brands, frosting quantity, and portion size.
