For the Filling

6largeGolden Delicious apples
2tablespoonsgranulated sugar
1tablespoonground cinnamon(see recipe note #2)
Instructions
Preheat oven to 350 °F (177 °C).
Butter a 9 × 13-inch baking dish.
To Make Topping: Add all topping ingredients to a medium bowl (flour through walnuts) and stir until well combined. Melt butter in a saucepan over medium-low heat and pour over flour mixture; stir well until no dry flour remains.
For Filling: Peel apples (if desired). With a paring knife, cut into quarters and remove core. Cut quarters in half lengthwise, then slice crosswise into 1/4-inch thick pieces. Transfer apple slices to a medium bowl and sprinkle with sugar and cinnamon; stir to coat evenly. Transfer to prepared baking dish, spreading into an even layer.
Tip bowl of topping over apples and use a fork to distribute evenly, breaking up any large chunks.
Bake for 40 to 45 minutes or until apples are tender and topping is crisp and golden brown. Serve warm.
Notes
If using unsalted butter, add another 1/4 teaspoon fine salt or 1/2 teaspoon kosher salt.
For a more subtle spice, reduce the cinnamon in the apples to 2 teaspoons.
Store leftovers tightly covered in the refrigerator for up to 5 days or freeze for up to 3 months.
This recipe makes ample crisp topping - if you like a thinner layer, reduce the topping ingredients by 1/3.
