Layer slices of peaches over the batter. Although the batter has such a liquid like consistency, the peaches will not sink into the batter. It will hold up perfectly by the fluffy cake layer structured mostly by beaten egg whites.
If you are using almonds, you have the option to either sprinkle it over the peaches before baking or do so after the baking process.
If you don’t like almonds, simply skip adding them to the recipe.
Bake for approximately 40-45 minutes, or until the center is barely moving and the top feels firm when touched. A skewer inserted in the middle of the cake should come out clean once baked.
Start checking the cake after 30 minutes as baking time may vary depending on your oven or pan. Do not over bake the cake as this will cause it to become rubbery and lose its custard layer.
If the top is browning too quickly before it's baked, then shape foil into a dome and place it over the cake. It should not touch the batter.
Once baked, turn the oven off. Open the oven door but leave the cake in the oven for 5 minutes. This prevents it from collapsing too abruptly due to the sudden temperature change.
Remove the cake from the oven, leave it in the pan to cool for 30 minutes.
Refrigerate: Leave the cake in the pan and refrigerate for 1 hour, allowing the custard to set. The cake will shrink down slightly as it cools and this is normal
Remove the cake from the fridge, Sift powdered sugar over the top if you like. Use the overhang of the parchment paper to lift the cake out of the pan. Then slice into portions and serve.
