Sour Cream Apple Squares

A sour cream apple slice bar topped with whipped cream and walnuts on a white plate.

These Sour Cream Apple Squares have tender apples, a hint of cinnamon and a buttery brown sugar and walnut crust that tastes a bit like a cinnamon graham cracker. Serve them at room temperature or slightly warm with whipped cream or vanilla ice cream for an easy fall dessert.

Ingredients

2 cups all-purpose flour
2 cups packed brown sugar
½ cup butter, softened
1 cup chopped walnuts
1 cup sour cream
1 ½ teaspoons cinnamon
1 teaspoon vanilla extract
1 teaspoon baking soda
1 egg
½ teaspoon salt
2 cups peeled, cored and chopped apples (about 2 medium apples)
Whipped cream or vanilla ice cream for serving, optional

Instructions

Preheat the oven to 350°F. Lightly coat a 9×13-inch metal cake pan with cooking spray. If desired, line the pan with parchment paper, leaving an overhang on two opposite sides.
In a large mixing bowl, combine the flour, brown sugar and softened butter. Mix with a hand mixer until the mixture forms moist crumbs. Stir in the walnuts.
2 cups all-purpose flour, 2 cups packed brown sugar, ½ cup butter, softened, 1 cup chopped walnuts
Measure 2¾ cups of the crumb mixture into the prepared pan. Use the bottom of a measuring cup to press it firmly and evenly across the bottom of the pan.
Add the sour cream, cinnamon, vanilla, baking soda, egg and salt to the remaining crumb mixture. Mix on low just until combined. Fold in the chopped apples.
1 cup sour cream, 1 ½ teaspoons cinnamon, 1 teaspoon vanilla extract, 1 teaspoon baking soda, 1 egg, ½ teaspoon salt, 2 cups peeled, cored and chopped apples (about 2 medium apples)
Spoon the apple mixture over the crust and spread it into an even layer.
Bake for 35–40 minutes, or until the top is golden brown, the center looks set and a toothpick inserted near the center comes out mostly clean without wet batter.
Let the squares cool completely in the pan. Use the parchment-paper overhang to lift them from the pan, then cut into 24 squares. Serve as they are or top with whipped cream or vanilla ice cream.
Whipped cream or vanilla ice cream for serving, optional

Notes

To make a half batch in a 9×9-inch pan: Halve all the ingredients. After preparing the crumb mixture, press 1⅜ cups into the prepared pan for the crust. Bake for 25–27 minutes, or until the top is golden brown, the center is set and a toothpick comes out mostly clean.

To halve the egg, whisk it until evenly combined and use half by weight. Without a kitchen scale, measure approximately 1½ tablespoons of beaten egg.
