Banana Chocolate Cookies

Bread flour: The higher protein content of bread flour gives these cookies a slightly chewier, more structured texture compared to all-purpose. It helps them hold their shape while staying soft in the center.

Dutch processed cocoa powder: This is important! Don't substitute with regular unsweetened cocoa. Dutch processed cocoa has been treated to reduce acidity, which gives it a smoother, richer, more intensely chocolate flavor and that deep, dark color that makes these cookies look as good as they taste.

Baking soda: Gives the cookies a little lift and helps them spread evenly in the oven.

Salt: Balances the sweetness and enhances the chocolate flavor. Don't skip it.

Unsalted butter: At room temperature so it beats smoothly with the sugars. Softened butter gives you a tender, evenly textured cookie.

Vanilla extract: Adds warmth and rounds out the chocolate flavor.

White granulated sugar and light brown sugar: The combination of both is what gives these cookies their texture. White sugar helps them spread and gives the edges a slight crispness, while brown sugar adds moisture and a subtle caramel note that works beautifully with the banana and chocolate.

Egg: Binds the dough and adds richness. Bring it to room temperature along with the butter for the smoothest batter.

Banana: One small ripe banana - about 90g (mashed). The riper the better. An overripe banana with lots of brown spots is sweeter, more fragrant, and mashes more smoothly into the dough. It keeps the cookies moist and adds a subtle banana flavor that pairs naturally with the chocolate.

Chocolate chips: Semi-sweet or milk chocolate both work here. Semi-sweet gives a slightly more intense chocolate hit, while milk chocolate makes the cookies sweeter and creamier. Use whichever you prefer or a mix of both.

Use a very ripe banana. The riper the banana, the sweeter and more flavorful the cookies. A yellow banana with lots of brown spots is ideal. An underripe banana won't mash as smoothly and won't add as much flavor to the dough.

Don't skip the chilling time. The dough needs 20-30 minutes in the fridge before baking. Banana adds moisture to the dough, which makes it soft and sticky at room temperature. Chilling firms it up so you can scoop it into neat balls that hold their shape in the oven rather than spreading too thin.

Use Dutch processed cocoa, not natural cocoa. This makes a real difference to the flavor and color of the cookies. Natural cocoa is more acidic and has a sharper, fruitier flavor. Dutch processed is smoother, richer, and gives you that deep, almost black color that makes these cookies look stunning.

Don't overbake. These cookies continue to cook on the hot baking sheet after you take them out of the oven. Pull them when they look puffy, have finished spreading, and the tops no longer loo. 

Let them cool on the baking sheet. Ten minutes on the baking sheet before transferring is important. Fresh out of the oven these cookies are fragile and will break if you move them too soon. Patience pays off.

Use a cookie scoop for even results. A 3 tablespoon cookie scoop gives you 16 evenly sized cookies that all bake at the same rate. Uneven sizes mean some will be overbaked while others are still raw in the center.

Mix the dry ingredients: Whisk together the flour, cocoa powder, baking soda, and salt. Set aside.

Make the dough: Beat the butter, both sugars, and vanilla extract until a paste-like consistency. Add the mashed banana and mix to combine, then add the egg and beat again. Add the dry ingredients and mix until just combined. Fold in the chocolate chips.

Chill: Cover the dough and refrigerate for 20-30 minutes until firm enough to scoop.

Bake: Scoop 16 dough balls onto lined baking sheets, spacing about 2 inches apart. Bake at 350F (180C) for 11 minutes until puffy, spread, and no longer wet on top.

Cool: Allow to cool on the baking sheet for 10 minutes before transferring to a wire rack.

Nutty: Fold in some roughly chopped walnuts or pecans along with the chocolate chips. Nuts and banana are a classic combination, and the crunch works really well against the soft, fudgy cookie.

Sea salt finish: Sprinkle a small pinch of flaky sea salt on top of each cookie just before baking. It makes the chocolate taste more intense and the whole cookie more addictive.

Peanut butter chips: Swap half the chocolate chips for peanut butter chips. Banana, chocolate, and peanut butter is one of the great flavor combinations and it works brilliantly here.
