Il Fornaio bakery in Los Angeles made a recipe for almond cake that I fell in love with many years ago. I’ve changed their recipe a bit to create a different texture, but the pronounced almond flavor remains the same. It’s very important to cream the butter and almond paste until it becomes thoroughly smooth.
Position The Rack in the center of the oven and preheat the oven to 350 degrees F. Butter and flour an 8-inch round cake pan.
In a medium bowl, whisk together the cornmeal, cake flour, and baking powder. Using a stand mixer with a paddle attachment, beat the butter and almond paste on high speed until smooth, about 3 minutes. Reduce the speed to low and beat in the vanilla extract. Gradually add 1¼ cups of confectioners’ sugar, beating until the mixture is light and fluffy, about 3 minutes. Increase the speed to high and beat in the egg yolks and whole eggs, one at a time. Reduce the speed to medium and add the sour cream and dry ingredients and mix until just incorporated.
Pour the batter into the prepared cake pan and smooth the surface with a spatula. Bake until the cake is golden and pulls away from the sides of the pan, about 35 minutes. Transfer the pan to a wire rack and let cool. Remove the cake from the pan and dust with more confectioners’ sugar. (The cake can be made 1 day ahead. Store airtight in a plastic container.) Cut the cake into wedges and serve.
