Method
Prep and bake
- Preheat oven to 375°F and line baking sheets with parchment, so the bottoms bake evenly without sticking.
- Beat butter and brown sugar until light and fluffy, then add the egg and vanilla and mix until smooth.
- Stir in mashed bananas; the batter may look slightly broken, and that is fine.
- Fold in flour, baking soda, baking powder, cinnamon, nutmeg, and salt until just combined.
- Fold in chocolate chips or chopped walnuts so they’re distributed throughout the dough.
- Drop heaping tablespoons onto prepared sheets, leaving 2 inches between each cookie.
- Bake for 10–12 minutes at 375°F until the edges are golden and centers are just set; do not overbake.
Notes
For best texture, let the dough rest 5 minutes after mixing so it thickens slightly for cleaner scoops. Store in an airtight container at room temperature for up to 3 days, or refrigerate up to 5 days; freeze baked cookies up to 2 months. For a dairy-free option, swap softened butter for a 1:1 plant-butter substitute to keep the cookies tender.
