German Apple Streusel Cake With Brown Sugar Mascarpone Cream

• For the apples:
• 4 sour apples (such as Granny Smith), washed, peeled, cored, and chopped
• The zest of 1 medium lemon
• 2 tablespoons lemon juice, or the juice from half the lemon
• 2 tablespoons granulated cane sugar
• For the crust/streusel topping, and mascarpone cream:
• 2 1/4 cups all purpose unbleached flour
• 1/2 cup granulated cane sugar
• 1/2 cup light brown sugar, lightly packed
• 1 1/2 teaspoons baking powder
• 1/2 teaspoon coarse kosher salt
• 1 teaspoon ground cinnamon (I like to be generous)
• 1/8 teaspoon ground cloves
• 1 pinch ground nutmeg
• 8 tablespoons melted unsalted butter, cooled
• 2 large eggs
• 1 teaspoon pure vanilla extract
• 4 tablespoons sour cream
• 4 tablespoons mascarpone cheese, softened
• 1 teaspoon pure vanilla extract
• 4 teaspoons light brown sugar

1. In a medium bowl, stir together the chopped apples, lemon zest, juice, and sugar. Set aside.
2. In a large bowl, whisk together the flour, both sugars, baking powder, salt, cinnamon, cloves, and nutmeg. Add the butter, eggs, and vanilla. Use a spatula to gently combine all of the wet ingredients into the dry. The mixture will be very thick.
3. Preheat the oven to 350*F. Coat a 10-inch round cake pan generously with nonstick spray and lightly dust the pan with flour, tapping out any excess. Set the pan on a rimmed baking sheet.
4. Use your fingers to press about two-thirds of the dough into the bottom and slightly up the sides of the prepared pan, creating a little lip all around the edge. Pour the apple mixture evenly on top of the dough. Crumble the remaining third of the dough over the apples, creating streusel crumbles.
5. Bake 40 to 45 minutes, rotating the pan around halfway through the baking time, until the apples are toothpick-tender, and the streusel topping is a deep golden brown. Let cool in the pan until easy to handle, then carefully invert onto a serving plate.
6. Top each slice with Brown Sugar Mascarpone Cream. In a small bowl, stir together sour cream, mascarpone cheese, vanilla extract, and light brown sugar until smooth and creamy.
