Butter or nonstick spray, for greasing pan
6 large, tart apples, such as Granny Smiths
3 large eggs
1 cup (200 grams) granulated sugar
1 teaspoon vanilla extract
1 cup (125 grams) all-purpose flour
Ground cinnamon, to finish
Powdered sugar, also to finish
Preheat oven to 350 degrees. Line the bottom of a 9-inch springform pan with parchment paper. Butter the paper and the sides of the pan. Peel, halve and core your apples, then chop them into medium-sized chunks. (I cut each half into four “strips” then sliced them fairly thinly — about 1/4-inch — in the other direction.) Pile the cut apples directly in the prepared pan. Meanwhile, in a large bowl, using an electric mixer or whisk, beat eggs with sugar until thick and ribbons form on the surface of the beaten eggs. Beat in vanilla, then stir in flour with a spoon until just combined. The batter will be very thick.
Pour over apples in pan, using a spoon or spatula to spread the batter so that it covers all exposed apples. Bake in preheated oven for 55 to 60 minutes, or until a tester comes out free of batter. Cool in pan for 10 minutes on rack, then flip out onto another rack, peel off the parchment paper, and flip it back onto a serving platter. Dust lightly with ground cinnamon.
Serve warm or cooled, dusted with powdered sugar. Alex’s family eats it plain, but imagine it would be delicious with a dollop of barely sweetened whipped or sour cream.
