Ingredients

For the Flaky Pie Dough

• All-purpose flour (4 cups) — The structural backbone of the crust. Its protein content forms gluten strands when hydrated, giving the dough strength while still baking into flaky pastry layers.
• Granulated sugar (1 tbsp) — A small amount that lightly sweetens the dough and encourages gentle caramelization, helping the crust develop that golden bakery finish.
• Salt (1 tsp) — A critical flavor enhancer. It balances sweetness, highlights butter richness, and prevents the crust from tasting flat.
• Unsalted butter (1¼ cups, chilled) — The heart of flakiness. When kept cold, butter remains in tiny pockets within the flour. During baking, those pockets steam and expand, forming thin crispy pastry layers that define Chicago bakery slices.
• Ice-cold water (½ cup + more as needed) — Hydrates the flour just enough to bind the dough without melting the butter. Cold water = better lamination, less spreading, more flake.

For the Gooey Apple Filling

• Apple pie filling (4 cups) — Provides sweet, syrupy, cinnamon-spiced apples that bake into a soft gooey center layer. Using prepared filling keeps the recipe fast while staying true to bakery-style flavor.

For the Bakery-Style Vanilla Glaze

• Powdered sugar (1 cup) — The base of the icing. Its fine texture dissolves quickly, forming a smooth glaze without graininess.
• Unsalted butter (2 tbsp, softened) — Adds shine, richness, and a luxurious mouthfeel to the glaze, making it taste like authentic bakery icing.
• Vanilla extract (1 tsp) — Enhances warmth and aroma, giving the glaze that classic bakery scent and flavor profile.
• Whole milk (2 tbsp) — Thins the glaze to a spreadable consistency while keeping it creamy and opaque. Whole milk adds more body than low-fat milk.

Step-By-Step Instructions

1. Prepare the Homemade Flaky Pie Dough

1. In a large bowl, whisk together flour, sugar, and salt until evenly blended.
2. Grate the chilled butter directly into the flour mixture, gently tossing between additions to keep butter coated and separated.
3. Make a well in the center and pour in the ice-cold water. Toss with a fork until the dough begins to clump together.
4. Turn onto a floured surface and knead just until combined. Do not overwork — visible butter bits are ideal for flake formation.
5. Divide in half, flatten into rectangles, wrap, and chill for minimum 30 minutes.

2. Assemble the Chicago-Style Apple Slices

1. Preheat oven to 400°F (200°C).
2. Line a 9×13-inch baking pan with parchment or grease lightly for clean removal.
3. Roll out the first dough rectangle and press it evenly into the pan — this forms the bottom flaky crust layer.
4. Spread apple pie filling evenly over the crust, edge to edge for maximum gooey bites.
5. Roll out the second dough rectangle and lay it gently on top. Add small vents to prevent steam buildup.
6. Crimp edges lightly and bake for 40 minutes or until golden and crisp.
7. Cool completely before glazing — this ensures clean cuts and set icing.

3. Make the Bakery-Style Vanilla Glaze

1. Beat powdered sugar, butter, milk, and vanilla until silky smooth and glossy.
2. Spread evenly over the cooled crust, letting it fall into every pastry layer crack.
3. Let the glaze set before slicing into squares or rectangles.

Pro Tips for Bakery-Perfect Apple Slices

• Use very cold butter — warmth destroys flakiness.
• Do not over-knead the dough — gluten overdevelopment makes crust tough.
• Cool fully before glazing — icing will melt and smear if warm.
• Slice with a sharp knife and wipe clean between cuts for bakery-clean edges.
• Always use parchment paper if serving at events — it guarantees neat removal and pro presentation.

Serving Suggestions

• Serve warm with vanilla ice cream for contrast between hot apples and cold cream.
• Drizzle extra glaze or caramel to create a glossy gourmet finish.
• Dust with cinnamon sugar for added aroma and visual appeal.
• Pair with hot cider, coffee, or spiced chai — a bakery-style beverage match.
• Pack for bake sales, holidays, potlucks, and dessert boards — holds shape beautifully.
