Chocolate Chip Butter Cake

This is a proper butter cake built from scratch with separated eggs, sifted cake flour, and a generous amount of creamed butter. What sets it apart is the coarsely grated German sweet chocolate folded into the batter and scattered across the top, giving you pockets of melty chocolate throughout with a crackly chocolate-flecked crust.

Separating the eggs is what makes this cake so light. The yolks go into the creamed butter and sugar for richness, and the whipped whites get folded in last to add lift. Don’t skip the folding step or rush it. You want to keep as much air in those whites as possible so the crumb stays tender and tall.

Alternating the dry ingredients with the milk keeps the batter smooth without overmixing, which would toughen the cake. Three additions of each, beating just until combined after every pour.

Kitchen Tips

• Use room-temperature butter and eggs. Cold butter won’t cream properly, and cold whites won’t whip to stiff peaks.
• Sift the cake flour before measuring. It’s already a lighter flour, and sifting ensures an extra-fine crumb.
• Grate the chocolate on the large holes of a box grater. Too fine and it melts completely into the batter instead of giving you distinct chocolate pockets.
• Check for doneness at 35 minutes with a toothpick. Overbaking dries out butter cakes fast.

Variations

• Use semisweet or bittersweet chocolate instead of German sweet for a deeper, less sugary chocolate flavor.
• Add a teaspoon of almond extract alongside the vanilla for a bakery-style twist.
• Dust the cooled cake with powdered sugar or drizzle with a simple vanilla glaze.
