Prep and Cook Time
- Preparation: 15 minutes
- Baking: 35-40 minutes
- Total: 50-55 minutes
Yield
Serves: 8 generous slices
Difficulty Level
Easy – Perfect for bakers of all experience levels
Ingredients
- 1 ½ cups all-purpose flour, sifted
- ¾ cup unsweetened cocoa powder, high quality
- 1 ½ teaspoons baking soda
- ½ teaspoon salt
- 1 cup granulated sugar
- 1 cup mayonnaise (use full-fat for best results)
- 3 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup whole milk, warmed slightly
- ½ cup hot water
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper.
- In a large bowl, sift together the flour, cocoa powder, baking soda, and salt. This ensures the mixture is light and free of lumps, crucial for the cake’s delicate crumb.
- In a separate bowl, whisk the sugar and mayonnaise until smooth and creamy. The mayonnaise acts as a tenderizer, bringing unmatched moistness.
- Add the eggs one at a time, beating well after each addition. The eggs bind the structure and elevate the richness.
- Stir in the vanilla extract for that deep, inviting aroma.
- Gradually alternate adding the dry ingredients and warmed milk to the wet mixture, beginning and ending with the dry. Mix gently but fully to avoid overmixing, which can toughen the cake.
- Slowly pour in the hot water, stirring until just combined. The hot water helps bloom the cocoa, intensifying the chocolate notes and loosening the batter for a perfect rise.
- Pour the batter into the prepared pan, smoothing the top with a spatula.
- Bake for 35-40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Resist opening the oven early to prevent deflation.
- Allow the cake to cool in the pan for 10 minutes before transferring it onto a wire rack to cool completely.
Expert Tips for Perfecting Moistness and Elevating Presentation
- Use full-fat mayonnaise to maximize moisture and flavor – low-fat varieties won’t impart the same silkiness.
- Warm your milk slightly (not hot) to help meld the ingredients seamlessly and boost batter fluidity.
- For best texture, sift your dry ingredients thoroughly to avoid dense patches or lumps in your cake.
- After baking, allow the cake to cool fully to prevent frosting from melting and losing its glossy appearance.
- Pair this cake with a lush chocolate ganache or a softly whipped cream to heighten indulgence and presentation.
- decorate with fresh raspberries or edible flowers for a striking visual contrast and fresh flavor lift.
- Make-ahead tip: This cake stores well wrapped in plastic wrap at room temperature for up to two days or in the refrigerator for up to five days. Bring to room temperature before serving for softness.
