Step 1

Roll out and place one pie crust into the bottom and sides of a 9-inch pie plate, trimming to the edge of the pie plate all the way around. Preheat the oven to 375 degrees F.

Step 2

For the filling, in a large bowl, toss the apples with the lemon juice. Add the brown sugar, granulated sugar, flour, cinnamon, nutmeg and salt. Stir to combine. Add vanilla and cream and mix.

Step 3

In a large pot, melt the butter over medium heat. Add the apple mixture and cook for about 6-8 minutes, stirring often (and adjusting the heat if the apples start to stick to the bottom of the pot) to soften the apples just a bit.

Step 4

Scoop the apple mixture into the pie shell and spread evenly.

Step 5

In the same bowl you used for the filling dry ingredients, combine the flour and sugar. Cut in the butter with a fork or your fingers until the mixture resembles coarse crumbs. Stir in the chopped toffee bars. Sprinkle this mixture over the top of the apples.

Step 6

Roll out the top pie crust and place it on top of the pie. Leave a 1/4- to 1/2-inch overhang all the way around. Fold the top crust over the bottom crust and underneath. Press lightly to seal. Flute the edges and cut a few long slits in the top to vent the pie.

Step 7

Beat the egg white with a teaspoon of water and brush the top of the pie with the egg mixture. Sprinkle lightly with sugar.

Step 8

Place the pie on a baking sheet (to avoid any potential leaks dripping into your oven) and bake for about 50-60 minutes until the crust is golden and the apples are soft and tender. Serve warm or at room temperature.
