Preheat oven to 350 degrees with a rack in the middle of the oven. Lightly coat 2 (9-inch) cake pans with nonstick vegetable spray. Line the bottoms with a circle of baking parchment.

Into a large bowl, sift the flour, baking powder and salt together, 3 times. In a small saucepan, bring the milk and butter to a boil. Remove from the heat and add the vanilla and lemon extracts. In separate mixing bowl, beat the eggs and sugar until pale yellow, and fluffy, and doubled in volume. While still beating, drizzle in the hot milk mixture. Fold in the flour mixture. Spread the batter in the prepared pans and bake for 15 minutes, or until golden, the center springs back when lightly pressed, and a cake tester comes out clean. Set the pans on a rack to cool. Run the tip of a knife around the edges of the cakes to loosen them, and turn them out of the pans.

Whipped Cream Frosting: In a medium bowl, mix together the gelatin and 1/4 cup of the cream. Let rest for 5 minutes to soften, then place the bowl over barely simmering water until the gelatin has completely dissolved. Remove the bowl from the heat and let cool to tepid. In the meantime, in a mixing bowl, whip the cream until slightly thickened. Add the confectioners' sugar and vanilla and whip to the consistency of shaving cream. Fold 1/2 cup of the whipped cream into the gelatin mixture, then fold in the rest.

Wash and dry the strawberries. Pick out the 12 best. Stem and slice the rest. Lay the sliced berries over 1 cake, then spread a 1/2-inch layer of whipped cream on top. Place the second cake over the first. Frost the entire cake with the remaining whipped cream. Top with the 12 whole berries.
