Instructions

1. Step 1: Preheat oven to 375°F (190°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
2. Step 2: In a large bowl, whisk together 2 cups all-purpose flour, 3/4 cup granulated sugar, 2 tsp ground cinnamon, 1/2 tsp baking powder, and a pinch of salt.
3. Step 3: Add 1 cup cold cubed unsalted butter to the flour mixture. Using a pastry cutter or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
4. Step 4: Reserve 1 1/2 cups of this crumb mixture for the topping, then press the remaining crumbs evenly into the bottom of the prepared pan to form the crust.
5. Step 5: In a separate bowl, toss 3 peeled and diced medium apples with 1 tbsp lemon juice, 1/4 cup brown sugar, 1 tbsp cornstarch, and 1 tsp vanilla extract until evenly coated.
6. Step 6: Spread the apple mixture evenly over the crust layer.
7. Step 7: Sprinkle the reserved crumb topping evenly over the apples.
8. Step 8: Bake for 40-45 minutes until the top is golden brown and the apples are tender when pierced with a fork.
9. Step 9: Let cool completely in the pan on a wire rack before lifting out and cutting into bars for serving.
