Banana Snickerdoodle Bars

01Method

1. 1

   Heat the oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving an overhang on all sides for easy removal.

2. 2

   In a bowl, whisk together the flour, cream of tartar, baking soda, salt, the smaller portion of cinnamon, and the nutmeg until combined.

3. 3

   Using an electric mixer, cream the butter with the larger portion of white sugar and the brown sugar until pale and fluffy. On low speed, mix in the banana and vanilla extract until fully incorporated, then fold in the flour mixture just until a dough forms. With lightly floured hands, press the dough evenly into the prepared pan.

4. 4

   Stir together the tablespoon of white sugar and the remaining cinnamon, then scatter the mixture evenly over the surface of the dough.

5. 5

   Bake until the center feels firm to a light touch, approximately 25 minutes.

6. 6

   Allow the bars to rest in the pan for 10 minutes, then lift out using the parchment overhang and transfer to a wire rack to cool fully before cutting into 16 pieces.
