Ingredients and Their Roles

For the Crust and Crumb Topping

• 2 ½ cups all-purpose flour – provides structure for the crust and crumb layers.
• 1 cup unsalted butter, cold and cubed – ensures a rich, flaky texture and buttery taste.
• 1 cup light brown sugar – adds sweetness and subtle molasses depth.
• ½ teaspoon baking powder – gives a light lift to prevent density.
• ¼ teaspoon salt – balances sweetness and enhances flavor.
• 1 teaspoon vanilla extract – adds warmth and aroma.

For the Apple Filling

• 4 cups apples, peeled and thinly sliced – the star of the dessert, juicy and tender when baked.
• 2 tablespoons all-purpose flour – thickens the filling to prevent sogginess.
• ¼ cup granulated sugar – sweetens and balances tart apples.
• ¼ cup brown sugar – provides caramelized richness.
• 1 teaspoon ground cinnamon – classic spice that defines the apple flavor.
• ¼ teaspoon ground nutmeg (optional) – adds earthy warmth.
• 1 teaspoon lemon juice – brightens the flavor and preserves color.

Step-by-Step Instructions

Step 1: Prepare the Pan and Oven

Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal after baking.

Step 2: Make the Crust and Crumb Mixture

In a large bowl, combine flour, brown sugar, baking powder, and salt. Add the cold butter and vanilla extract. Using your fingers or a pastry cutter, mix until the texture resembles coarse crumbs. Reserve about 1½ cups of the mixture for the topping.

Step 3: Form the Base

Press the remaining mixture evenly into the bottom of the pan. Bake for 10–12 minutes until lightly golden, then set aside to cool slightly.

Step 4: Prepare the Apple Filling

In a bowl, toss sliced apples with granulated sugar, brown sugar, flour, cinnamon, nutmeg, and lemon juice until evenly coated and glossy.

Step 5: Assemble the Layers

Spread the apple mixture evenly over the baked crust. Sprinkle the reserved crumb mixture evenly on top, leaving it loose and crumbly for the best texture.

Step 6: Bake

Bake for 40–45 minutes until the top is golden brown and the apple filling is bubbling around the edges.

Step 7: Cool and Slice

Let the bars cool completely in the pan before slicing. Lift them out using the parchment overhang and cut into even squares or rectangles.

Pro Tips for Perfect Bars

• Always use cold butter to achieve that signature crumb texture.
• Do not overbake; the bars firm up as they cool.
• Mix apple varieties like Granny Smith and Honeycrisp for a balance of tartness and sweetness.
• Chill before cutting for neat slices and a clean presentation.
• Make ahead — they taste even better the next day as flavors meld together.
