# The Ingredients You'll Need:

→ Crust & Crumble

01 - 2 ½ cups all-purpose flour
02 - ¾ cup granulated sugar
03 - ¾ cup light brown sugar, packed
04 - 1 teaspoon baking powder
05 - ½ teaspoon salt
06 - 1 cup cold unsalted butter, cubed
07 - 1 large egg
08 - 1 teaspoon vanilla extract

→ Apple Filling

09 - 6 cups peeled, thinly sliced Granny Smith or Honeycrisp apples
10 - ½ cup granulated sugar
11 - ¼ cup brown sugar
12 - 2 tablespoons cornstarch
13 - 1 ½ teaspoons cinnamon
14 - ¼ teaspoon nutmeg
15 - 1 tablespoon lemon juice
16 - 1 teaspoon vanilla extract

→ Glaze (optional)

17 - 1 cup powdered sugar
18 - 2–3 tablespoons milk
19 - ½ teaspoon vanilla extract

# Step-by-Step Instructions:

01 - Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
02 - In a bowl, whisk together flour, granulated sugar, brown sugar, baking powder, and salt. Cut in cold butter until mixture resembles coarse crumbs. Add egg and vanilla extract, mixing until a soft dough forms.
03 - Press about two-thirds of the dough firmly into the bottom of the prepared pan to create an even crust layer.
04 - In a large bowl, toss the sliced apples with granulated sugar, brown sugar, cornstarch, cinnamon, nutmeg, lemon juice, and vanilla extract until apples are evenly coated.
05 - Spread the apple mixture evenly over the crust base. Crumble the remaining dough over the apples to create a topping.
06 - Bake in the preheated oven for 45–50 minutes until the topping is golden brown and the filling is bubbling at the edges.
07 - Allow to cool at room temperature for at least 45 minutes to ensure filling sets.
08 - Whisk powdered sugar, milk, and vanilla extract until smooth. Drizzle glaze evenly over cooled bars.
09 - Cut into bakery-style squares and serve.

# Extra Tips:

01 - Using tart apple varieties such as Granny Smith or Honeycrisp ensures a balanced sweetness and tartness in the filling.
