Ingredients

- 1 1/4 cups all-purpose flour

- 3/4 teaspoon cream of tartar

- 1/2 teaspoon baking soda

- 1/4 teaspoon salt

- 1/4 teaspoon ground cinnamon

- 1/8 teaspoon ground nutmeg

- 1/2 cup unsalted butter, softened

- 1/2 cup white sugar

- 1/4 cup firmly packed brown sugar

- 1/2 cup mashed banana

- 2 teaspoons vanilla extract

Cinnamon Sugar

- 1 tablespoon white sugar

- 1/2 teaspoon ground cinnamon

Directions

- Preheat the oven to 350 degrees F (175 degrees C). Line an 8x8-inch square pan with enough parchment paper to have overhang on all sides.

- Whisk flour, cream of tartar, baking soda, salt, 1/4 teaspoon cinnamon, and nutmeg together in a bowl.

- Beat butter, 1/2 cup white sugar, and brown sugar in a large bowl with an electric mixer until light and fluffy. Beat in banana and vanilla extract on low speed until thoroughly combined; mix in flour mixture just until dough comes together. Using lightly floured hands, press dough firmly and evenly into the bottom of the prepared pan.

- Whisk together the 1 tablespoon white sugar and 1/2 teaspoon cinnamon; sprinkle cinnamon sugar evenly over the dough.

- Bake in the preheated oven just until the dough in the center of the pan feels set when lightly touched with a finger, about 25 minutes.

- Let bars cool in the pan for 10 minutes before removing to a wire rack to cool completely. Cut into 16 bars.
