Apple Danishes are the perfect way to ring in the apple season! The flaky crust, apple pie filling, crumb topping, and simple glaze make them irresistible.
Preheat the oven to 400 degrees Fahrenheit and line two baking sheets with parchment paper.
In a medium saucepan, combine 4 tablespoons unsalted butter, ½ cup granulated sugar, ¼ cup water, 2 teaspoons cornstarch, ½ teaspoon cinnamon, ½ teaspoon nutmeg, and a pinch of salt.
Melt over medium heat and bring the mixture to a boil. Boil for 2 minutes, stirring frequently, then add in 2 large peeled and diced Granny Smith apples. Bring the mixture back to a boil over medium-high heat and cook for 5 minutes, stirring often. Remove from heat and let cool.
Unfold 1 (17.3-ounce) box puff pastry dough (two sheets). Using a rolling pin roll out each sheet to 10x10 inches. Use a pizza cutter and make 12 even strips. Connect two strips together by overlapping by a half inch and pressing together. Twist the the strips around itself and press the end to the rest of the dough.
Place 6 danishes on a parchment lined baking sheet pan then press the middle down. Place a spoonful of the apple filling in the middle of each danish.
