Method
Step 1: Make the Crust
- In a large bowl, whisk together the flour and salt. Cut in the cold butter with a pastry cutter or two forks until the mixture looks like coarse crumbs. Stir in the egg yolk and milk until the dough comes together.
- Press two-thirds of the dough into a parchment-lined 9×13-inch pan. Chill the remaining third of the dough in the fridge while you prepare the filling.
Step 2: Make the Apple Filling
- In a large bowl, toss the apples with both sugars, flour, cinnamon, nutmeg, and vanilla extract. Let it sit for 5 minutes so the flavors can mingle.
- Spread the apple mixture evenly over the crust.
Step 3: Add the Topping
- Crumble the remaining dough over the apples. It doesn’t need to cover them completely—those peek-through apples look beautiful when baked.
- Brush the top with beaten egg white and sprinkle generously with turbinado sugar.
Step 4: Bake
- Bake at 350°F (175°C) for 40–45 minutes or until the top is golden brown and the apple filling is bubbling around the edges.
- Let the bars cool completely in the pan before slicing. This part is hard, but it helps them set up nicely.
