Ingredients

  • 1 cup plus 2 teaspoons gluten-free all-purpose flour, divided
  • 2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 3/4 cup packed light brown sugar, divided
  • 1/4 cup mini chocolate chips (1-1/2 ounces)
  • 1/2 cup chopped walnuts
  • 1 teaspoon cinnamon
  • 2 large eggs, at room temperature
  • 1/2 cup sugar
  • 1/2 cup canola oil
  • 2 teaspoons pure vanilla extract
  • 2 large apples, cored, peeled and cut into 1/2-inch pieces

Method

  • Preheat the oven to 375°. Lightly grease a 9-in. round baking or springform pan. In a large bowl, whisk together 1 cup flour, baking powder and salt. In a small bowl, stir together the remaining 2 teaspoons flour, 1/2 cup brown sugar, chocolate chips, walnuts and cinnamon.
  • In another small bowl, whisk together the eggs, granulated sugar and remaining 1/4 cup brown sugar until smooth. Whisk in the oil and vanilla. Stir into the flour mixture until just combined. Pour half the batter into prepared pan, top with half the apples and half the crumb mixture; repeat with the remaining batter, apples and crumb mixture. Bake until a toothpick inserted in the center comes out clean, 30-35 minutes.
