Passover is upon us, and last night Mike and I had our annual interfaith seder. Three Catholics, three Protestants, and one Jew celebrated the story of the exodus along with a ton of food, including my traditional orange almond cake (this time made with Valencia oranges for the best result yet) and a new, delicious treat. I found this recipe for flourless walnut cake at Food 52, and it is life-changing.
The thing about Passover baking is: no flour. So what’s a baker to do? Ground nuts and eggs feature heavily in Passover cake recipes, and that was the case with this cake as well. It was my first experience whipping egg whites separately, then folding them into batter. Full disclosure: I had to start over with the whites because holy cow, it’s easy to over-whip egg whites. In any case, the end result was absolutely delicious, tasting almost like the nut filling in a nut roll pastry. The cake sinks in the middle as it cools, leaving a wonderful indentation for a pool of freshly whipped cream. I’ll absolutely make this cake again, for many occasions, and may try hazelnuts or pecans next time.
- 8 ounces ground walnuts
- 9 ounces superfine sugar
- 6 eggs, separated, at room temperature
- 1 teaspoon cinnamon
- 1 teaspoon vanilla extract
- Whipped cream, for serving
Preheat oven to 350 degrees. Line the bottom and sides of a 9-inch springform pan with parchment paper.
In a mixer fitted with the paddle attachment, beat egg yolks and sugar until fluffy and light in color, about 8-10 minutes. Stir in cinnamon and vanilla extract.
In a separate bowl, whip egg whites to soft peaks. (Not sure how to do that? Watch this.) In three parts, carefully and gently fold the whites into the batter.
Gently pour batter into prepared pan and bake for 30-35 minutes, until a cake tester inserted in the center comes out clean, or with just a few small moist crumbs. Cool in pan about 10 minutes, then open the pan and peel back the paper, allowing the cake to cool completely. The cake will sink in the middle as it cools, and this is perfectly fine. Fill the indentation with fresh whipped cream, candied walnuts, or whatever you like. Store a plain cake at room temperature; if you’ve added whipped cream on top, keep it in the fridge.
