Ingredients

• 1.25 cups all-purpose flour
• 0.75 teaspoons cream of tartar
• 0.5 teaspoons baking soda
• 0.25 teaspoons salt
• 0.25 teaspoons ground cinnamon
• 0.13 teaspoons ground nutmeg
• 0.5 cups unsalted butter , softened
• 0.5 cups white sugar
• 0.25 cups brown sugar
• 0.5 cups banana
• 2 teaspoons vanilla extract

Instructions

1. 1 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.
2. 2 Whisk flour, cream of tartar, baking soda, salt, 1/4 teaspoon cinnamon, and nutmeg together in a bowl.
3. 3 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.
4. 4 Whisk together the 1 tablespoon white sugar and 1/2 teaspoon cinnamon; sprinkle cinnamon sugar evenly over the dough.
5. 5 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.
6. 6 Let bars cool in the pan for 10 minutes before removing to a wire rack to cool completely. Cut into 16 bars.
