Ingredients

For the Crust and Crumb Topping:

• 2½ cups all-purpose flour
• 1 cup granulated sugar
• ½ teaspoon baking powder
• ½ teaspoon ground cinnamon
• 1 cup (2 sticks) cold unsalted butter, cubed
• 1 large egg

For the Apple Filling:

• 5 cups peeled and diced apples (like Granny Smith or Honeycrisp)
• ½ cup granulated sugar
• 2 tablespoons all-purpose flour
• ½ teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg

Instructions

Step 1: Preheat the Oven
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.

Step 2: Make the Crust and Crumble Topping
In a large bowl, stir together flour, sugar, baking powder, and cinnamon.
Cut in the cold butter using a pastry cutter, fork, or your hands until the mixture resembles coarse crumbs.
Add the beaten egg and stir until evenly mixed.
Press half the mixture firmly into the bottom of your prepared pan to form the crust.

Step 3: Prepare the Apple Filling
In a separate bowl, combine diced apples with sugar, flour, cinnamon, and nutmeg.
Toss to coat the apples evenly.
Spread the apple mixture over the crust layer in the baking pan.

Step 4: Add the Crumb Topping
Sprinkle the remaining crumb mixture over the apple layer. Let some larger chunks form for that perfect rustic crumble texture.

Step 5: Bake
Bake for 40–45 minutes, or until the top is golden brown and the apples are tender.
Your kitchen will smell like a warm bakery — cinnamon, apples, butter… magic.

Step 6: Cool & Slice
Let the bars cool completely in the pan before slicing. This helps them firm up and hold their shape when served.
Cut into squares or bars, depending on how generous you’re feeling.
