Grandma's Chocolate Layer Cake

A proper old-fashioned chocolate layer cake made the way your grandmother would have made it: butter creamed with sugar, eggs beaten in one at a time, melted baking chocolate folded through, and the dry ingredients alternating with cold water until the batter comes together smooth and glossy.

The alternating-additions method matters more than most home bakers realize. Dumping all the flour in at once produces pockets of dry flour that no amount of mixing dissolves evenly. Adding flour and water in small batches (starting and ending with flour) lets each addition incorporate properly and produces an even, tender crumb without over-developing gluten.

Cold water is the specific liquid called for, and it makes a difference. Room-temperature or warm water melts the butter back out of the emulsion; cold water keeps the creamed butter-sugar-egg structure intact, giving you a lighter cake with better volume. Melt the chocolate gently and cool it to room temperature before adding; hot chocolate scrambles the egg proteins in the batter.

Two 9-inch round pans bake in 30 minutes at 350°F (175°C). Test with a toothpick at the 28-minute mark; it should come out with a few moist crumbs, not wet batter. Frost with any chocolate or vanilla buttercream once fully cool.

Baking Tips

• Line the cake pans with waxed paper or parchment on the bottom, in addition to greasing. This guarantees clean release after baking.
• Slice off domed tops with a serrated knife to level the layers before stacking. Flat layers stack evenly; domed layers tilt.
• Place the first layer upside down (bottom side up) for the flattest surface to frost. The second layer goes right-side up for a smooth top.
• Cool layers completely before frosting. Warm cake melts buttercream into a slippery mess.

Variations

• Swap baking chocolate for 6 tablespoons of cocoa powder mixed with an extra 2 tablespoons of butter for a slightly different flavor profile.
• Add a teaspoon of instant espresso powder to the dry ingredients for deeper chocolate flavor.
• Fill with raspberry jam between the layers under the frosting for a chocolate-raspberry twist.
