Ingredients List

For the Crust

  • 1 cup (2 sticks) unsalted butter, softened to room temperature
  • 1/3 cup granulated sugar
  • 1/4 cup lightly packed light brown sugar
  • 1 teaspoon pure vanilla extract
  • 2 cups all-purpose flour
  • 3/4 teaspoon kosher salt
  • 1/3 cup finely chopped walnuts
  • 1 teaspoon ground cinnamon

For the Filling

  • 3 lbs apples (about 4 medium, e.g., Gala, Braeburn, Golden Delicious, Pink Lady), peeled, cored, and cut into 1/4 inch slices
  • 1 tablespoon fresh lemon juice
  • 3 tablespoons granulated sugar
  • 1.5 teaspoons ground cinnamon
  • 1/2 teaspoon freshly grated nutmeg
  • 2 tablespoons unsalted butter
  • 1 teaspoon cornstarch

Timing

Prep Time

  • 20 minutes

Cook Time

  • 45 minutes

Total Time

  • 1 hour 5 minutes

Step-by-Step Instructions

Step 1: Prepare the Oven and Baking Pan

Preheat your oven to 375°F. Line an 8×8 square baking pan with parchment paper for easy removal and cleanup.

Step 2: Make the Crust

In a mixing bowl, beat the softened butter, granulated sugar, light brown sugar, and vanilla extract until creamy. In a separate bowl, whisk together the flour, kosher salt, ground cinnamon, and finely chopped walnuts. Gradually add the dry ingredients to the wet mixture until just combined.

Step 3: Press the Crust into the Pan

Press two-thirds of the dough mixture into the prepared baking pan. Chill in the refrigerator for 20 minutes to firm up.

Step 4: Pre-Bake the Crust

Bake the crust in the preheated oven for 18-20 minutes, or until golden brown. Once baked, remove from the oven and let it cool slightly.

Step 5: Prepare the Filling

In a large skillet, melt the 2 tablespoons of butter over medium heat. Add the sliced apples, lemon juice, granulated sugar, ground cinnamon, and freshly grated nutmeg. Cook for about 15 minutes, stirring occasionally, until the apples are tender. Sprinkle the cornstarch over the apple mixture, stirring until thickened.

Step 6: Assemble the Squares

Spread the apple filling evenly over the pre-baked crust. Crumble the remaining dough over the top of the apple filling.

Step 7: Bake the Squares

Return the pan to the oven and bake for an additional 25-30 minutes, or until the top is golden and crisp. Allow the squares to cool completely before cutting them into bars.

Common Mistakes to Avoid

  2. Using the Wrong Apples: Choose apples that hold their shape when baked, like Gala, Braeburn, or Granny Smith, for the best results.
  3. Not Chilling the Dough: Chilling helps the crust maintain its shape during baking; don’t skip this step!
