1-First, preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan to get everything ready.

2-In a large bowl, combine the melted butter, sugar, salt, and egg yolks, mixing until they’re fully integrated for a smooth base.

3-Next, add the flour and stir until just combined remember, avoiding overmixing keeps the texture light and crumbly, which is a tip I’ve learned from my own kitchen mishaps.

4-Once mixed, reserve 2 cups of the dough mixture and press the rest firmly into the base of your prepared pan to form the crust.

5-For the apple filling, peel and thinly slice the apples, choosing a variety like Granny Smith or Honeycrisp that holds its shape well during baking.

6-Toss the apples with sugar, cinnamon, and nutmeg until evenly coated, then spread this mixture evenly over the crust in the pan.

7-Now, take the reserved dough and crumble it into pea-sized pieces, sprinkling them over the apple layer to create that irresistible crumb topping.

8-Pop the pan into the oven and bake for 50 60 minutes, until the topping is golden brown and the filling is bubbling away.

9-Finally, let it cool completely before slicing and serving patience here makes for the best results.
