Gently transfer batter into an ungreased 10-inch tube pan with a removable bottom. Run a thin-bladed knife through the batter (to release any air bubbles) and, using a rubber spatula, smooth the top. Bake until cake is lightly browned and springs back from a light touch, about 35 to 40 minutes.
Remove from the oven, and immediately turn pan upside down on a wire rack (if pan doesn't have legs, invert it over the neck of a wine or other long-necked bottle). Cool cake, upside down, for at least 2 hours.
When ready to serve, turn pan right side up and run a long, sharp, thin-bladed knife along the edges and the center tube. Give cake a gentle shake to loosen it from the pan, and invert to a plate or rack. Using a small metal spatula, separate the cake from the pan's bottom and center core, then invert again so cake is right side up. Slice, using a serrated knife, and serve with fresh berries (or a fruit compote) and freshly whipped cream. The cake can be kept in an airtight container at room temperature for up to 3 days.
