Gluten-Free Chestnut Cake

In this cake, almonds and chestnuts replace flour entirely. Without a gluten network, the cake's structure relies on whipped egg whites. It's a delicate balancing act resulting in a 'soufflé-cake' that is light as a cloud yet rich in flavor. As it cools, the chestnut starch sets the final texture.

Instructions

1

Mix egg yolks with melted butter and room temperature chestnut puree until smooth.

Tip: Everything must be the same temperature to prevent the butter from seizing.
2

Stir in almond flour, cocoa powder, baking powder, and vanilla. It will be a thick batter.

Tip: Almond flour is heavy, so the baking powder provides extra lift.
3

Whip egg whites with sugar and salt to medium peaks. (The peak should curl slightly at the tip).

Tip: If too stiff (dry), it's hard to fold into the heavy batter without breaking bubbles.
4

Lighten the chestnut mixture with one-third of the whites, then gently fold in the rest.

Tip: Tempering the density difference helps preserve air.
5

Bake at 340°F (170°C - lower temp!) for about 40 minutes.

Tip: Almonds and chestnuts burn easily. The cake densifies as it cools, which is normal.

Recipe FAQ

Why did the center collapse?
You took it out too early (internal structure hadn't set), or you overbeat the eggs, making the air bubbles unstable.
