1cupall-purpose flour,fluffed, spooned and leveled
⅓cupalmond flour(or very finely ground almonds)
½tspbaking powder
¼tspcoarse Kosher salt(if using table salt, use half the amount)
2large egg whites
½cuppowdered sugar
1cupsliced almonds
Instructions
Preheat the oven to 350 F, and position a rack in the center of the oven. Prepare a 9-inch baking pan by spraying it with non-stick baking spray, or prepping it with butter and flour. I like to bake this cake in a 9-inch ruffled pie pan, and serve it right from the pan.
In a bowl, whisk together the melted butter, granulated sugar, egg, egg yolk, vanilla, almond extract, milk and lemon zest.
In a separate bowl, whisk together the flour, almond flour, baking powder and salt. Add the dry ingredients to the wet, and whisk until combined. Spread the batter evenly into the pan.
In a bowl, vigorously whisk together the egg whites and powdered sugar, until foamy, then stir in the almonds. Dollop the egg white/almond mixture over the cake batter.
Bake the cake for about 35-40 minutes, until the topping is golden brown. Note that at 35 minutes, the cake will be slightly underdone in the center, for more of a "custardy" texture. Bake for 40 minutes for a more "set" texture.
Let the cake cool for 30 minutes, then serve warm. Decorate the top of the cake with a few more sliced almonds.
Notes
Store leftover cake in an airtight container at room temperature for up to 3 days.
