4cupspeeled and chopped Granny Smith apples (410 grams) - about 4 large apples
½teaspooncinnamon
Remaining ingredients
2sheets puff pastry
1large egg beaten with 1 tablespoon water(egg wash)
Instructions
Preheat oven to 400 degrees F. Line 2 baking sheets with parchment paper.
Make custard. Heat milk in a medium saucepot over medium heat until warm.
Combine egg, egg yolks, sugar, and cornstarch in a heat safe bowl, whisking until well combined. Slowly add the warm milk to the egg mixture, whisking constantly. Pour the custard back into the pot and simmer over medium-low heat. Continue to cook until thickened, about 5 minutes, stirring the custard constantly. Remove from heat and add dulce de leche, butter, and a pinch of salt, whisking until the butter is melted. Transfer custard to a bowl and place plastic wrap directly on the surface of the custard to prevent skin from forming. Let cool completely.
Prepare apple filling. Add butter and brown sugar in a medium sauce pot and melt over medium heat. Add apples and cinnamon, stirring to combine. Cook until apples are softened, stirring occasionally, about 8-10 minutes. Let cool completely.
Lightly dust a clean work surface with flour. Unwrap the puff pastry and cut it into 6 equal rectangles. Use a knife and score a ¼-inch border on each rectangle, making sure not to actually cut the pastry. Place 1 heaping tablespoon of the custard in the center of each pastry, making sure not spread it outside of the border. Place 1 heaping tablespoon of the apple filling on top.
Brush edges of pastry with egg wash. Bake Danish for 17-20 minutes or until golden brown. Remove from oven and let cool slightly. Drizzle extra dulce de leche on top, if desired. Serve warm or at room temperature.
