Instructions

• Preheat the oven to 350 degrees F and set a rack to the middle of the oven.
• In a large bowl, combine the flour, almond flour, sugar, cinnamon, baking powder, and salt. Work in the cold butter until the mixture is crumbly. Add water and mix until just combined.
• Press ⅔ of the crumble mixture into the bottom of a 9-inch springform pan. Bake for 12 to 15 minutes until slightly golden. Set aside to cool.
• In an electric mixer, mix mascarpone, cream cheese, and sugar on high until fluffy. Add eggs one at a time, then mix in vanilla and apple cider vinegar.
• Pour the mascarpone filling into the crust, arrange sliced apples on top, and sprinkle with remaining crumble mixture.
• Bake in the oven for one hour until the topping is golden brown and the center jiggles slightly.
• Cool to room temperature, then refrigerate for at least 2 hours before serving. Dust with powdered sugar before serving.
