Nothing says apple season quite like a slice of German Apple Cake. With tart Granny Smith apples nestled into a tender, buttery cake and a light dusting of powdered sugar, this dessert is simple, cozy, and absolutely irresistible.
Arrange an oven rack to the bottom third of the oven. Preheat the oven to 350°F. Grease the bottom of a 9-inch springform or line with parchment paper.
Prepare the apples. Peel the apples, then cut them into quarters and remove the core. Thinly slice each quarter lengthwise without cutting all the way through. Squeeze some lemon juice over the apples to prevent them from turning brown. Set aside.
In a medium bowl, whisk together the flour, baking powder and salt. Set aside.
In the bowl of a stand mixer (or using a hand mixer), beat butter and sugar until light and creamy, about 2 minutes. Add eggs one at a time and mix well after each addition. Scrape down the sides and bottom of the bowl as necessary. Mix in the vanilla and 1 teaspoon lemon zest.
With the mixer running on low, add half of the flour mixture, then the milk, followed by the remaining flour. Beat just until combined (do not over-mix).
Transfer batter to the prepared pan and spread into an even layer. Arrange the apples on top with the sliced side facing up.
Bake at 350°F for 45 minutes or until lightly browned and a toothpick inserted in the center comes out with little to no crumbs.
Cool in the pan for 15 minutes, then remove the springform ring and let the cake cool completely. Right before serving, sprinkle cake with powdered sugar.
Notes
Granny Smith apples are best for their tart flavor and crisp texture. Honeycrisp and Braeburn are good alternatives.Store covered at room temperature for 2 days or in the refrigerator for 4 days.
