New York-Style Peach Crumb Cake

Method

1. 1

   Preheat oven to 350°F. Grease a 9x9-inch pan with spray or butter and set aside.

2. 2

   Make the streusel: whisk together the flour, granulated sugar, brown sugar, cinnamon, and salt. Rub in the butter with your fingers until the mixture looks like wet sand. Set aside.

3. 3

   Make the cake: cream the butter, granulated sugar, baking powder, and salt until light, about 3 minutes. Beat in 3 eggs plus 1 egg yolk one at a time, reserving the egg white. Mix in the vanilla, then add the flour and mix until just combined with no dry pockets.

4. 4

   Spread the batter evenly in the prepared pan and tap it on the counter a few times to release air bubbles.

5. 5

   Whisk the reserved egg white into the peach preserves and spread it in a thin, even layer over the batter.

6. 6

   Scatter the streusel over every inch of the batter, gently pressing it so it sticks. Bake 30–33 minutes, until a toothpick inserted in the center comes out clean.

7. 7

   Cool at least 15 minutes. Dust with powdered sugar if you like, then slice and serve.
