  • 1 cup (226g) unsalted butter, melted
  • cups (350g) dark brown sugar, tightly packed
  • 2 large eggs + 1 egg yolk, room temperature
  • teaspoons vanilla extract
  • cups (285g) all-purpose flour
  • 2 teaspoons cornstarch
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 3 medium Granny Smith apples, peeled, cored, and diced into small pieces (approximately 2¼ cups)
  • ½ teaspoon apple pie spice

Maple Glaze

  • ¼ cup pure maple syrup
  • 2 tablespoons butter
  • ½ cup confectioners' sugar


  1. Preheat the oven to 350°F and prepare an 8x8-inch baking dish by lining it with parchment paper (or lightly grease and flour). (You could use a 9x13-inch baking dish for more servings, but the bars will be thinner.)

  2. Using a whisk, combine the melted butter and brown sugar in a large bowl. Mix well.

  3. Add the eggs and the egg yolk, one at a time, stirring well after each addition, scraping the sides of the bowl as needed.

  4. Whisk in the vanilla extract.

  5. In a separate, medium-sized bowl, whisk together the flour, cornstarch, baking powder, and salt.
  6. Using a rubber spatula, gradually stir the flour mixture into the butter and egg mixture until completely combined.

  7. Fold in diced apples.

  8. Spread the batter evenly into the prepared pan.
  9. Bake for 50-55 minutes, or until the edges just begin to turn golden brown and there is no jiggle in the bars. (If you are using a 9x13-inch pan, bake for about 45 minutes.)

  10. Allow blondies to cool before topping with maple glaze.

Maple Glaze

  1. Melt the maple syrup and butter over medium-low heat and whisk until fully incorporated.

  2. Remove from heat and add the confectioners' sugar, whisking to combine.

  3. Drizzle over the cooled blondies. Cut and serve.
