Flaky, buttery layers filled with warm spiced apples and brown sugar cinnamon—these homemade toaster strudels are nostalgic, gooey, and glazed to perfection.
Puff Pastry (or use 2 store-bought sheets)
1⅔ cups all-purpose flour
1 teaspoon salt
1 cup cold butter, grated
½ cup Greek yogurt (or sour cream)
¼ cup water
2 tablespoons buttermilk (or milk + splash of vinegar or lemon)
1 large egg + 1 tablespoon water (egg wash)
Turbinado sugar, for topping
Apple Filling
2 tablespoons butter
2 apples, peeled and diced
¼ cup brown sugar
2 tablespoons maple syrup
1 teaspoon cinnamon
½ teaspoon apple pie spice
Pinch of salt
2 teaspoons cornstarch + 1 tablespoon water (slurry)
1 teaspoon vanilla extract
Brown Sugar Cinnamon Filling
½ cup brown sugar
1 tablespoon all-purpose flour
2 teaspoons cinnamon
2 tablespoons butter, melted
1 teaspoon vanilla extract
Pinch of salt
Glaze
1 cup powdered sugar
¼ cup browned butter
¼ cup maple syrup
1 tablespoon milk
1 teaspoon vanilla extract
Pinch of salt
Make the Apple Filling
In a skillet over medium heat, cook butter, apples, brown sugar, maple syrup, cinnamon, apple pie spice, and salt until apples are soft.
Stir in cornstarch slurry and cook until thickened.
Remove from heat, stir in vanilla, and cool completely.
Make the Cinnamon Filling
In a bowl, mix brown sugar, flour, cinnamon, melted butter, vanilla, and salt until smooth. Set aside.
Assemble the Strudels
Roll puff pastry into a 20×9-inch rectangle. Cut into 16 equal rectangles.
Spoon cinnamon filling and apple filling onto half of the rectangles.
Top with remaining rectangles. Seal edges with a fork.
Bake
Preheat oven to 400°F (205°C).
Brush tops with egg wash and sprinkle with turbinado sugar.
Bake for 17–20 minutes, until golden and puffed.
Glaze & Finish
Whisk all glaze ingredients until smooth.
Drizzle glaze over warm strudels and serve.
Let fillings cool fully before assembling to prevent leaks.
Store-bought puff pastry works great for a quicker version.
Freeze unbaked strudels and bake straight from frozen (add 2–3 minutes).
Best enjoyed warm, but leftovers keep well for 2 days.
