Ingredients
- 1 cup (120g) all-purpose flour
- 1/2 cup (100g) granulated sugar
- 1/2 cup (113g) unsalted butter, cold and cubed
- 1/4 teaspoon salt
- 1 cup (70g) old-fashioned oats
- 1/2 cup (100g) brown sugar, packed
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon salt
- 3 cups (375g) peeled and thinly sliced Granny Smith apples
- 1 tablespoon lemon juice
- 1 tablespoon all-purpose flour
- 1/2 teaspoon vanilla extract
- 1/4 cup (28g) chopped walnuts (optional)
- 1/4 cup (28g) additional brown sugar for topping

Instructions
- Step 1: 1
Prepare Crust: In a medium bowl, combine flour, 1/2 cup sugar, 1/2 cup butter, and 1/4 teaspoon salt. Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs. Press the mixture firmly into the bottom of a greased 9x13-inch baking pan.
💡 Tip: For extra crispness, chill the crust for 15 minutes before adding the filling.
- Step 2: 2
Make Filling: In a large bowl, toss sliced apples with lemon juice and 1 tablespoon flour. In a separate small bowl, mix 1/2 cup brown sugar, cinnamon, nutmeg, 1/4 teaspoon salt, and vanilla. Spread the apples evenly over the crust. Sprinkle the cinnamon-sugar mixture over the apples.
💡 Tip: For a deeper flavor, let the filling sit for 15 minutes while you prepare the topping.
- Step 3: 3
Make Topping: In a medium bowl, combine oats, 1/4 cup brown sugar, 1/2 cup butter, and chopped walnuts. Mix until the butter is evenly distributed and the mixture forms clumps. Spread the topping evenly over the apples.
💡 Tip: For a crisper topping, use cold butter and handle the mixture as little as possible.
- Step 4: 4
Bake: Bake at 350°F (175°C) for 45-50 minutes, or until the topping is golden brown and the apples are bubbly. Let cool completely before cutting into bars.
💡 Tip: For a warm serving option, reheat individual bars in the microwave for 10-15 seconds.
