Whip Up a Perfect Sponge Cake

Foolproof Sponge Cake

A quick look through an old manuscript cookbook will tell you right away what housewives considered important, something that should be written down and saved. A hundred years ago, it was sponge cakes.

These tiny cakes were a “must” for afternoon teas. For a last-minute dessert, it may have been a couple of sponge layers with a fruit filling, a backdrop for homemade ice cream, or the base for a Boston Cream Pie.

No one seems to know exactly when sponge cakes first appeared on the dessert table — the first mention recorded was in a letter written by Jane Austen in 1808 (and yes — she liked them).

In Victorian literature it seems that a sponge cake was always being whipped up by the family cook, or being perfected by marriageable daughters; you will note, “whipped up” is the key phrase.

Sponge cakes only can be produced by the whipping method — egg yolks are beaten with the sugar, then other ingredients are added. Once you get the idea of whipping lightly — too much is sure disaster, then folding the batter without deflating the mixture, the labor involved is just “a piece of cake.”

The baking time often is fewer than 20 minutes, depending on the size of the cake. At this time of the year, sponge cake pairs up perfectly with ripe berries, sliced peaches or nectarines with whipped cream on top. Easy and quick, it’s perfect summertime fare.

This recipe was developed by the tireless Cook’s Illustrated group and they called it “foolproof.” It makes two 8-inch or 9-inch layers, and it should be noted that the egg whites should not be beaten to a really stiff state — “soft, glossy and billowy” are the key words.

Foolproof Sponge Cake

1/2 cup cake flour
1/4 cup all-purpose flour
1 tsp. baking powder
1/4 tsp. salt
3 Tbsps. milk
2 Tbsps. unsalted butter
1/2 tsp. vanilla extract
5 eggs, room temperature
1/4 cup sugar

Grease two 8- or 9-inch cake pans and cover the bottoms with parchment. Set oven to 350 degrees with rack in the lower middle position.

Whisk flours, baking powder and salt in a medium bowl. Heat milk and butter in a small saucepan over low heat until the butter melts. Remove from heat and add vanilla. Cover and keep warm.

Separate three eggs. Put the whites in a bowl of a standing mixer. Put the three yolks plus the two whole eggs in another mixing bowl. Beat the three whites on high speed until foamy, then gradually add six Tablespoons of the sugar. Continue beating until you have soft, moist peaks.

Beat the yolk and whole egg mixture with the remaining six Tablespoons of sugar on medium speed until thick and pale yellow in color, about five minutes.

Add the beaten eggs to the whites.

Sprinkle flour mixture over the beaten eggs and whites. Fold very gently 12 times with a large rubber spatula. Make a well in one side of the batter and pour milk mixture into he bowl. Continue folding until the batter shows no trace of the flour and the whites and whole eggs are evenly mixed. This only will  take about eight additional strokes.

Immediately pour the batter into the prepared baking pans. Bake until the layers are light brown on top and feel firm. They should spring back when touched.

The time should be about 16 minutes for a 9-inch cake and 20 minutes for 8-inch cake pans.

Run a knife around the cakes to loosen them. Cover pan with a large plate, invert and remove cake. Set a rack over the cake and reinvert again.

When the layers are cool, you might consider this simple dessert:
