Celebrate Passover with a chiffon cake so tender and airy, you'll be tempted to make it year-round (even if you don't observe the Jewish holiday). To keep it kosher, whipped egg whites act as the only leavener, and coconut oil replaces butter.

Ingredient Checklist


Instructions Checklist
  • Preheat oven to 350 degrees. In a small bowl, whisk together matzo meal, potato starch, and salt. In a large bowl, beat egg whites on medium-high to soft peaks. Gradually add 3/4 cup sugar and beat until stiff (but not dry) peaks form. In another large bowl, beat egg yolks with remaining 3/4 cup sugar and vanilla seeds until pale and doubled in volume, about 5 minutes. Gradually beat in 3 tablespoons oil, then coconut milk, just until combined. Add matzo mixture; beat just until combined. Stir in one-third of egg whites, then gently fold in remaining whites in two additions, just until combined and no streaks remain (do not overmix). Transfer to an ungreased 10-inch tube pan (preferably footed) with a removable bottom; smooth top with an offset spatula.

  • Bake cake until golden on top and a tester inserted in center comes out clean, 40 to 45 minutes. Invert pan and let cool completely. If pan is not footed, invert center of tube onto the neck of a bottle to allow air circulation.

  • Turn cake right-side up. Run a thin, sharp knife around sides of pan and center tube. Lift cake by center tube; remove ring. Run knife around bottom of pan to loosen; invert cake to remove. Place on a plate or stand. Combine remaining oil and chocolate in a bowl. Place over (but not in) a pot of simmering water; stir until melted. Remove from heat and place over an ice-water bath, stirring constantly, until thickened slightly but still pourable, 1 to 2 minutes. Pour frosting evenly over top and sprinkle with coconut. Cut into wedges; serve.

Cook's Notes

The frosting should be pourable, like brownie batter. If it gets too thick, microwave itfor 10 seconds at a time to thin it.
