Instructions
Mix the wet base
In a large bowl, combine the melted butter, brown sugar, and mashed banana. Mix until glossy and fully unified.
Add the egg yolk and vanilla extract, then mix until the mixture thickens slightly.
Fold in the dry ingredients
Add the flour, salt, baking soda, and cinnamon. Stir just until no dry streaks remain—stop as soon as it comes together to avoid over-developing gluten.
Fold in the chocolate chips gently to keep the dough tender.
Rest the dough while the oven heats
Cover the dough and let it rest for about 15 minutes while the oven preheats. This short hydration helps the cookies bake up chewier.
Scoop, bake, and cool
Line a cookie sheet with parchment paper and preheat the oven to 350°F. Once preheated, scoop 1-ounce dough balls and space them about 2 inches apart.
Bake for 10 to 11 minutes, until the edges are set and the tops look puffed, but the centers still look slightly underbaked.
Let the cookies cool before eating—they finish setting as they cool, which locks in that chewy center.
Notes
Measurement tip: Treat the “1/4 cup” mashed banana as a rule. Too much banana adds excess moisture and pushes the texture toward cakey or rubbery.Mixing tip: Once the flour goes in, stir only until you no longer see dry streaks to avoid tough cookies from gluten development.Butter option: If using butter, you can brown it until golden and nutty, then stir the cinnamon into the warm fat before mixing for deeper flavor.Baking tip: Pull the cookies when the centers still look slightly underbaked; they set up as they cool and stay gooey and chewy.Serving idea: Finish with a pinch of flaky sea salt to deepen the chocolate flavor.Storage: Store airtight at room temperature for 2 to 3 days. Adding a piece of bread to the container helps prevent the cookies from getting overly soft.Freezing dough: Scoop into balls, freeze on a tray until firm, then transfer to a sealed bag. Bake from frozen at 350°F, adding time as needed until edges are set and centers still look slightly underbaked.Freezing baked cookies: Cool completely, wrap tightly, freeze, then thaw at room temperature. A brief warm-up helps bring back the fresh-baked gooey center.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
