Step-by-Step Guide to Making Apple Slab Dessert

Step 1: Prepare the Dough

1. In a bowl, mix flour and salt.
2. Cut in the butter until the mixture resembles coarse crumbs.
3. Add the egg yolk and milk mixture; stir until the dough forms.
4. Divide into two equal portions, wrap in plastic, and chill for 30 minutes.

Step 2: Assemble the Slab Pie

1. Roll out half of the dough to fit an 11×15 sheet pan, ensuring it goes up the edges.
2. Sprinkle the crust with crushed cornflakes—this prevents a soggy bottom.
3. Layer thinly sliced apples evenly over the crust.
4. Sprinkle sugar and cinnamon on top of the apples.
5. Dot with small pieces of butter.
6. Roll out the second half of the dough and place it over the filling, sealing the edges.

Step 3: Add the Egg White Topping

1. Whip the egg white to stiff peaks.
2. Spread it evenly over the top crust to give it a light, crispy texture when baked.

Step 4: Bake the Pie

1. Bake at 375°F for 45 minutes to 1 hour, or until golden brown.
2. Let it cool slightly before adding the glaze.

Step 5: Drizzle the Powdered Sugar Glaze

1. In a small bowl, mix powdered sugar, vanilla, and enough milk to reach a drizzle consistency.
2. Drizzle over the pie while it’s still warm for that perfect finishing touch.

Tips for the Best Homemade Apple Slab Pie
