Every year when Passover comes around, I face the same dessert dilemma. The kids want chocolate cake, but most Passover cake recipes produce dense, heavy results that leave everyone disappointed. After years of tweaking and testing, I finally cracked the code for a chocolate sponge cake that’s actually light and airy without using flour.

This recipe relies on properly whipped eggs to create structure instead of gluten. The secret is separating your eggs and whipping the whites to soft peaks before folding them in gently. I use Dutch-process cocoa powder for the deepest chocolate flavor, plus a touch of potato starch to give the cake just enough body without weighing it down. The result tastes like a cross between chocolate mousse and traditional sponge cake.

Why Egg Separation Makes All the Difference

What really makes this cake special is how it improves after sitting overnight. The flavors meld together, and the texture becomes even more tender. I’ve served this to non-Passover guests who couldn’t believe it was made without flour. The cake holds up beautifully to fresh berries or a simple dusting of powdered sugar.

This works perfectly as a Passover dessert, but honestly, I make it year-round now because it’s lighter than regular chocolate cake. It pairs wonderfully with fresh strawberries or a scoop of pareve vanilla ice cream. The whole thing comes together in about an hour, and you probably have most of the ingredients already.

Ingredients Method Notes

Ingredients
  

  • 6 large eggs room temperature, separated
  • 3/4 cup granulated sugar divided
  • 1/2 cup Dutch-process cocoa powder sifted
  • 2 tablespoons potato starch
  • 1/4 cup vegetable oil
  • 2 tablespoons warm water
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1 tablespoon powdered sugar for dusting, optional

Method
 

  1. Preheat oven to 350°F (175°C). Grease a 9-inch springform pan with oil and dust lightly with cocoa powder.
  2. In a large bowl, whisk egg yolks with 1/2 cup sugar until pale and thick, about 3 minutes. Mix in oil, warm water, vanilla, and salt.
  3. Sift cocoa powder and potato starch together, then whisk into egg yolk mixture until smooth.
  4. In a clean bowl with clean beaters, whip egg whites until foamy. Gradually add remaining 1/4 cup sugar and beat until soft peaks form.
  5. Fold 1/3 of egg whites into chocolate mixture to lighten it, then gently fold in remaining whites in 2 additions until just combined.
  6. Pour batter into prepared pan and smooth top gently. Bake 32-35 minutes until cake springs back when lightly touched.
  7. Cool completely in pan before removing sides. Dust with powdered sugar before serving if desired.

Notes

Cake improves after sitting overnight wrapped at room temperature. Store covered for up to 3 days. For best results, make sure egg whites are completely free of yolk traces before whipping. Don't overmix when folding in egg whites to maintain the light texture.
