Marbled Coffee Cake

Austrian bakers make this coffee cake with a special gugelhupf mold. We've found that a 1 1/2-qt. Bundt cake mold works just as well. This recipe hails from the 200-year-old Austrian pastry shop Demel, which Nick Malgieri profiled in "Vienna's Sweet Empire" (March 2009).


  • 17 tbsp. unsalted butter, softened
  • 1 34 cups flour
  • 2 oz. semisweet chocolate, preferably 54%, roughly chopped
  • 2 tbsp. dark rum
  • 3 tbsp. cornstarch
  • 12 tsp. salt
  • 12 cup confectioners' sugar, plus more for dusting
  • 2 tbsp. lemon zest
  • 1 tbsp. vanilla extract
  • 5 eggs, separated
  • 1 cup sugar


Step 1

Heat oven to 325°. Grease a dark metal 1 1⁄2-qt. gugelhupf mold with 1 tbsp. butter. Add 1⁄4 cup flour and shake to evenly coat the inside of mold. Invert and tap out excess flour; set mold aside. Set a medium bowl over a 1-qt. saucepan of simmering water. Add chocolate; melt. Stir in rum and set aside to let cool slightly.

Step 2

Sift together remaining flour, cornstarch, and salt; set aside. In a bowl, beat remaining butter, confectioners' sugar, lemon zest, and vanilla using a handheld mixer on medium speed until mixture is pale and fluffy, about 2 minutes. Add egg yolks one at a time, beating after each addition. Add reserved flour mixture to butter mixture in 3 additions, beating to combine after each addition. Set batter aside.

Step 3

In a large nonreactive bowl, beat egg whites with handheld mixer on high speed until frothy. Sprinkle in sugar and beat to form stiff, glossy peaks. Whisk one-third of egg whites into reserved cake batter to lighten it. Using a rubber spatula, fold in remaining egg whites to make an airy cake batter.

Step 4

Fold one-third of the cake batter into the reserved chocolate mixture to make a chocolate-flavored batter. Spoon half of the remaining cake batter into the buttered mold. Spoon all the chocolate batter into mold and top with remaining cake batter. Using a butter knife, swirl the chocolate batter into the cake batter to create a marbled effect. Smooth the top. Bake until a toothpick inserted in the cake comes out clean, about 55 minutes. Transfer cake to a rack; let cool. Unmold cake and dust with confectioners' sugar.
