These apple cinnamon blondies are soft and chewy with fresh apple pieces, warm cinnamon, and a crisp cinnamon sugar topping. An easy fall dessert for an after-school snack or something sweet after dinner.
Preheat the oven to 350°F. Line a 9×9-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
In a medium mixing bowl, whisk together the sugar and melted butter until combined.
1 cup granulated sugar, ½ cup butter
Add the egg, egg yolk and vanilla. Whisk until fully combined.
1 tablespoon vanilla extract, 1 egg, 1 egg yolk
In a small mixing bowl, whisk together the flour, cinnamon, baking powder and salt.
1 cup all-purpose flour, 1 teaspoon ground cinnamon, ¼ teaspoon baking powder, ½ teaspoon salt
Add the flour mixture to the butter mixture and fold together with a rubber spatula until just combined.
Fold in the diced apple. Transfer the batter to the prepared pan and spread into an even layer.
½ cup peeled
In a small bowl, stir together the sugar and cinnamon for the topping. Sprinkle three-fourths of the mixture evenly over the batter, reserving the rest for after baking.
¼ cup granulated sugar, ¾ teaspoon ground cinnamon
Bake for 25–27 minutes, or until the edges begin to brown and the center is set.
Remove from the oven and immediately sprinkle evenly with the remaining cinnamon sugar.
Allow to cool completely in the pan. Use the parchment paper to lift the blondies out of the pan, then slice into squares.

Notes
Dice the apple small: Small, evenly sized pieces distribute more easily throughout the batter.
Avoid overbaking: Start checking at 25 minutes to keep the centers soft.
Cool before slicing: Let the blondies cool so they hold their shape when cut.
