Heat the oven to 350°F with a rack in the middle position. Mist the bottom and sides of a 9-inch round cake pan with cooking spray, line the bottom with a round of kitchen parchment, then mist the parchment.

In a large bowl, combine the white sugar, whole eggs and egg whites, salt and both extracts. Whisk vigorously until well combined, 30 to 45 seconds; the mixture will be slightly frothy and the sugar will not be fully dissolved. Add the almond flour and whisk until incorporated.

Pour the batter into the prepared pan, then sprinkle evenly with the turbinado sugar and chopped almonds. Bake until deeply browned and the crust feels firm when gently pressed with a finger, 45 to 55 minutes. Let cool in the pan on a wire rack for 10 minutes.

Run a knife around the edges of the cake, then invert onto a plate. Remove the pan and parchment then re-invert the cake onto a serving plate. Let cool completely before serving.
