Ingredients
Method
Prep
- Preheat oven to 350°F. Line an 8×8 baking pan with parchment paper, leaving overhang to lift the bars out.
Mix Wet
- In a large bowl, mash 2 ripe bananas. Stir in melted butter, sugar, egg, and vanilla until smooth.
Mix Dry
- In a separate bowl, whisk flour, baking soda, salt, and pumpkin pie spice. Gently fold into wet mixture until just combined.
Add Chocolate
- Fold in ¼ cup chocolate chips.
First Layer
- Spread half the batter evenly into the prepared pan.
Middle Magic
- Lay 1 banana (halved lengthwise) over the batter. Warm Nutella in 15-second increments, stirring between, then drizzle over the bananas “like Picasso.”
Top Layer
- Spread remaining batter on top. Arrange the remaining 2 bananas (halved lengthwise) across the top layer. Drizzle with more warmed Nutella, swirl slightly with a knife if desired, and sprinkle with reserved chocolate chips. Finish with a light sprinkle of flaky sea salt.
Bake
- 40–45 minutes, or until a toothpick inserted into the center (avoiding Nutella pockets) comes out mostly clean.
Cool & Cut
- Let cool for at least 20 minutes. Lift out using the parchment and cut into big squares.
