Best Ever Fudge Cake

A chocolate Bundt cake that lives up to its name. The combination of cocoa powder and buttermilk creates a crumb so moist and fudgy it barely needs frosting. A simple dusting of powdered sugar is all the decoration this one requires.

Buttermilk is the secret weapon here. Its acidity reacts with the baking soda for great lift, and it tenderizes the crumb so the cake stays soft and dense in that satisfying, fudge-like way. The tang also sharpens the chocolate flavor, making the cocoa taste richer than it would with regular milk.

This is a straightforward cream-and-combine method. No melting chocolate, no tempering, no water baths. Mix it up, pour it in the Bundt pan, and 40 minutes later you’ve got a showpiece.

Pro Tips

• Spray every crevice of the Bundt pan thoroughly. Bundt cakes are notorious for sticking, and a fudgy batter clings more than most.
• Let the cake cool in the pan for exactly 15 minutes before inverting. Too soon and it falls apart. Too long and it fuses to the pan.
• Sift the cocoa powder before combining with the dry ingredients. Cocoa clumps stubbornly and leaves bitter pockets in the cake if not broken up.
• Test with a toothpick at 35 minutes. Every oven runs differently, and overbaking kills the fudgy texture.

Variations

• Drizzle with a chocolate ganache instead of powdered sugar for a more indulgent finish.
• Add a teaspoon of instant espresso powder to the dry ingredients. It doesn’t make the cake taste like coffee but intensifies the chocolate dramatically.
• Fold in a cup of mini chocolate chips for pockets of melted chocolate throughout.
