Mahogany Pound Cake

This chocolate pound cake earns its “mahogany” name from the deep, dark color that half a cup of cocoa and light brown sugar create together. It’s a true pound cake: dense, velvety, and rich, with a tight crumb that slices cleanly and stays moist for days.

Two sugars work together here. White sugar provides sweetness and structure, while brown sugar adds moisture and a subtle caramel undertone that deepens the chocolate flavor. Six eggs give the cake its lift and richness, and sour cream adds tang and an incredibly tender crumb.

The optional quick chocolate sauce is built on sweetened condensed milk, cocoa, and butter, cooked until thick and glossy. Poured warm over a slice of this cake, it turns an already impressive dessert into something genuinely show-stopping.

Chef Tips

• Beat the sugars and margarine until truly light and fluffy. This takes a solid 3 to 4 minutes and builds the structure that supports six eggs’ worth of batter.
• Add eggs one at a time, beating well after each. Dumping them all in at once breaks the emulsion and results in a dense, greasy cake.
• Alternate the sour cream and dry ingredients when adding to the batter. This prevents overmixing the flour (which toughens the cake) while keeping the batter smooth.
• Cool in the pan for 10 minutes before turning out. Too soon and the cake tears; too long and it sticks.

Variations

• Use butter instead of margarine for a richer, more traditional pound cake flavor.
• Add a teaspoon of instant espresso to the dry ingredients to intensify the chocolate without adding coffee flavor.
• Dust with powdered sugar for a simple finish, or glaze with a chocolate ganache for a more polished look.
