Café Au Lait Angel Food Cake

Ingredients

1 cup plus 2 tablespoons (4½ ounces/128 grams) cake flour 1 tablespoon instant coffee (or espresso powder)¼ teaspoon salt 1 ¾ cups (12¼ ounces/347 grams) granulated sugar 12 large egg whites 1 ½ teaspoons cream of tartar ½ teaspoon vanilla extract 1 tablespoon coffee liqueur

Before You Begin

Do not use all-purpose flour. Our tasters unflatteringly compared a cake made with it to Wonder Bread. If your angel food cake pan does not have a removable bottom, line the bottom of the pan with parchment paper. In either case, do not grease the pan (or the paper).

Instructions

    process sugar

  1. Adjust oven rack to lower-middle position and preheat oven to 325 degrees. Whisk flour, instant coffee, and salt in bowl. Process sugar in food processor until fine and powdery, about 1 minute. Reserve half of sugar in small bowl. Add flour mixture to food processor with remaining sugar and process until aerated, about 1 minute.
  2. beat whites

  3. With electric mixer on medium-low speed, beat egg whites and cream of tartar until frothy, about 1 minute. Increase speed to medium-high. With motor running, slowly add reserved sugar and beat until soft peaks form, about 6 minutes. Add vanilla and coffee liqueur and mix until incorporated.
  4. sift and fold

  5. Sift flour mixture over egg whites in 3 additions, folding gently with rubber spatula after each addition until incorporated. Scrape mixture into 12-cup ungreased tube pan.
  6. bake

  7. Bake until toothpick inserted into center comes out clean and cracks in cake appear dry, 40 to 45 minutes. Cool, inverted, to room temperature, about 3 hours. To unmold, run knife along interior of pan. Turn out onto platter. Serve.

Why This Recipe Works

The key Café au Lait Angel Food Cake is voluminous, stable egg whites. A mere speck of yolk precludes them from whipping to peaks. We had the best success with either cold or room-temperature egg whites. Cold whites whipped to the same volume as room-temperature eggs (they just took a few minutes longer). Cream of tartar offered some insurance against deflated whites. Its acidity helped stabilize the egg whites.
