Ingredients
Wet Ingredients
- 1/2 cup unsalted butter (112 grams), melted and slightly cooled
- 3/4 cup light brown sugar (157 grams), or 1/2 cup white sugar and 1/4 cup dark brown sugar
- 1 large egg
- 1 teaspoon vanilla bean paste
- 3/4 cup mashed bananas (180 ml), about 2 bananas, depending on size
Dry Ingredients
- 1 cup all-purpose flour (125 grams)
- 1/2 teaspoon cinnamon
- 1/4 teaspoon salt
Add-ins
- 1 cup chocolate chips (180 grams)
Instructions
- Prepare the Pan: Preheat your oven to 350°F (180°C). Lightly grease an 8×8 inch (20×20 cm) baking pan and line it with parchment paper, allowing an overhang on the sides for easy removal, or simply grease the pan if not using parchment.
- Mix Butter and Sugar: In a large bowl, whisk together the melted butter and light brown sugar until fully combined.
- Add Egg and Vanilla: Whisk in the egg and vanilla bean paste until the mixture is smooth and well incorporated.
- Incorporate Dry Ingredients: Gently stir in the all-purpose flour, cinnamon, and salt with a rubber spatula just until there are no streaks or lumps of flour remaining; avoid overmixing.
- Add Bananas: Fold in the mashed bananas until evenly distributed throughout the batter.
- Fold in Chocolate Chips: Carefully fold in the chocolate chips to the batter, ensuring an even spread.
- Bake: Spoon the batter into the prepared baking pan, spreading it evenly. Bake in the center of the preheated oven for 32-35 minutes. The top should appear set and a toothpick inserted should come out clean or with melted chocolate chips, but not raw batter.
- Cool and Slice: Allow the bars to cool in the pan for at least one hour. If lined with parchment, use the overhang to lift the bars out onto a cutting board before slicing. If not lined, slice directly in the pan.
Notes
- For a chewier, gooey texture, bake closer to 32 minutes; for a more cake-like texture, bake a few minutes longer.
- You can substitute light brown sugar with a mix of white and dark brown sugar for a slightly different sweetness profile.
- Ensure bananas are ripe for the best flavor and natural sweetness.
- Use room temperature eggs to help the batter mix evenly.
- Line the pan with parchment paper for easy removal and cleaner slicing.
- Store bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
