Method
Prepare and mix
- Preheat the oven to 350F, then grease a 9x13 baking pan.
- Mash the bananas until very smooth.
- Whisk the all-purpose flour, baking soda, baking powder, pumpkin pie spice, cinnamon, and salt.
- Whisk the mashed bananas, pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla until smooth.
- Fold the dry ingredients into the wet ingredients until just combined, then spread the batter evenly in the pan.
Bake, glaze, and slice
- Bake at 350F for 25-30 minutes, until a toothpick comes out clean.
- Cool the bars completely before glazing.
- Whisk the powdered sugar, maple syrup, and milk until smooth, then drizzle over the top in ribbons and cut into bars.
Notes
For the moistest bars, fold the dry into the wet just until the flour disappears—overmixing can make them tough. Store covered at room temperature for up to 2 days or in the refrigerator for up to 5 days; freeze bars (glaze after thawing if you want cleaner ribbons) for up to 2 months. For a dairy-free swap, use dairy-free milk in the maple glaze.
