Soft and Chewy Banana Chocolate Chip Cookies

Warm, tender, and fragrant with banana and chocolate, these cookies melt in your mouth the moment you bite them. banana chocolate chip cookies in this recipe get their softness from ripe mashed banana and a touch of cornstarch, not from extra oil or eggs, so the texture stays tender but not cakey. I developed and tuned this version over a dozen test bakes in a small test kitchen, trying different flours and banana ripeness levels until the balance felt right — soft edges, slightly chewy centers, and pockets of melted chocolate. This is the version I rely on when I need a quick treat for family or a bake-sale crowd.

These cookies are simple enough for busy parents and beginner bakers, yet precise enough that small technique choices make a real difference. Read on for a clear ingredients breakdown, step-by-step method, and pro tips so your batch turns out the same way every time.

Why This Recipe Works

Banana adds moisture and a ripe fruit aroma while contributing natural sweetness and softer crumb.
Brown sugar and an extra egg yolk increase chewiness and color through the Maillard reaction.
A small amount of cornstarch keeps the cookie tender by limiting gluten formation.
Lower oven temperature and short bake time set the edges while leaving the center soft.
Chilling the dough slightly controls spread so you get uniformly shaped cookies.

Ingredients Breakdown

300 g (2 1/2 cups) all-purpose flour — Provides structure. Too much and cookies get dry; spoon and level the flour for accuracy.
15 g (2 tbsp) cornstarch — Keeps the texture tender and soft.
1 tsp (6 g) baking soda — Leavening agent for light lift.
1/2 tsp (3 g) fine sea salt — Enhances sweetness and balances flavors. If using Morton kosher salt, increase slightly.
170 g (3/4 cup; 1 1/2 sticks) unsalted butter, softened — Adds richness and flavor. Use unsalted so you control salt.
150 g (3/4 cup) packed light brown sugar + 50 g (1/4 cup) granulated sugar — Brown sugar gives chew; granulated helps spread.
1 large egg + 1 large egg yolk — The extra yolk increases chew and richness without extra rise.
240 g (1 cup) mashed ripe banana — About 2 medium bananas; ripeness affects sweetness and banana flavor.
2 tsp (10 ml) pure vanilla extract — Flavor depth.
220 g (1 1/4 cups) semisweet chocolate chips or chopped chocolate — Use good-quality chocolate for melt and flavor. Rough-chopped chocolate gives better pools of melted chocolate.
Substitutions and impact warnings:
Greek yogurt for butter: You can replace up to 50 g butter with Greek yogurt to reduce fat, but cookies will be cakier and less rich.
Gluten-free: Use a 1:1 gluten-free flour blend and add 1/2 tsp xanthan gum; texture will be slightly more fragile.
Sugar swap: Replacing brown sugar with all granulated sugar will reduce chew and dark flavor.
Brand notes:
Use a reliable butter (European-style will yield richer flavor). If using coarse kosher salt like Morton, adjust salt down by half.

Essential Equipment

Mixing bowls: One medium and one large.
Electric mixer or sturdy wooden spoon: For creaming butter and sugar. A mixer speeds the job.
Kitchen scale: For accurate dry-ingredient weights — essential for consistent cookies.
Baking sheets: Two rimmed baking sheets. Line with parchment or silicone mats.
Cookie scoop (2 tbsp) or tablespoon: For uniform cookie size and baking time.
Cooling rack: For quick cooling and to prevent soggy bottoms.
If you don’t have a kitchen scale, use the volume equivalents and be careful to spoon and level flour; a packed cup will overmeasure.

Step-by-Step Instructions

This recipe makes about 24 cookies. Prep Time: 15 minutes. Cook Time: 10–12 minutes per batch. Inactive Time: 15 minutes chilling (optional). Total Time: ~40 minutes including chilling.

Step 1: Preheat and prepare pans

Preheat the oven to 175°C (350°F). Line two baking sheets with parchment paper or silicone mats. Position racks in the center and upper third of the oven so heat circulates evenly. This takes about 5 minutes.

Step 2: Whisk dry ingredients

In a medium bowl, whisk together 300 g (2 1/2 cups) all-purpose flour, 15 g (2 tbsp) cornstarch, 1 tsp (6 g) baking soda, and 1/2 tsp (3 g) salt for 20–30 seconds until evenly mixed. This step prevents clumps and distributes leavening.

Step 3: Cream butter and sugars

In a large bowl, beat 170 g (3/4 cup) softened unsalted butter with 150 g (3/4 cup) packed light brown sugar and 50 g (1/4 cup) granulated sugar until light and slightly fluffy, about 2–3 minutes on medium speed. Scrape the bowl once or twice. Creaming incorporates air that helps texture.

Step 4: Add eggs, banana, and vanilla

Beat in 1 large egg and 1 large egg yolk for 30 seconds. Stir in 240 g (1 cup) mashed ripe banana and 2 tsp (10 ml) vanilla extract until smooth, about 15–20 seconds. The banana should be well mashed with no large lumps.

Step 5: Combine wet and dry ingredients

Fold the dry ingredients into the wet in two additions, mixing until just combined — about 8–12 folds. Do not overmix — stop as soon as no dry flour is visible. Overmixing develops gluten and makes cookies tough. This takes about 30–45 seconds.

Step 6: Add chocolate and chill briefly

Fold in 220 g (1 1/4 cups) semisweet chocolate chips or chopped chocolate until distributed, about 10–15 seconds. For cleaner shapes and less spread, chill the dough for 15 minutes. This step is optional but helpful in warm kitchens.

Step 7: Portion and bake

Using a 2-tablespoon cookie scoop or tablespoon, drop mounds 5 cm (2 in) apart on the prepared baking sheets. Bake at 175°C (350°F) for 10–12 minutes. Rotate pans halfway through baking if your oven runs hot. Cookies are done when edges are set and tops are slightly cracked but centers still look soft.

Step 8: Cool and finish

Let cookies cool on the baking sheet for 5 minutes to set, then transfer to a cooling rack to finish cooling. Serve warm or at room temperature. Cooling and initial rest takes 10–15 minutes.

Expert Tips & Pro Techniques

Underbake slightly for a soft center: Pull cookies when centers look soft but edges are set; they firm up as they cool.
Common mistake: overmeasuring flour. Use a scale or spoon-and-level to avoid dry, dense cookies.
Fruit ripeness matters: bananas should be heavily freckled for best flavor and sweetness. Green bananas will reduce banana aroma.
Make-ahead: The dough can be scooped and frozen on a sheet; transfer scoops to a zip-top bag and freeze up to 3 months. Bake from frozen, add 2–3 minutes to bake time.
Professional trick: chill dough 24 hours for more developed flavor if you have time; add 3–4 minutes to baking time when chilled.
Swap chocolate style: mix chopped bittersweet for intense pockets and chips for texture contrast.

Storage & Reheating

Refrigerator: Store cooled cookies in an airtight container for up to 4 days. Add a slice of apple to keep them soft.
Freezer: Freeze baked cookies in a single layer on a sheet for 1 hour, then transfer to a freezer-safe bag for up to 3 months. Thaw at room temperature.
Reheating: Warm in a 175°C (350°F) oven for 5–7 minutes to refresh melt and softness. Avoid microwaving for more than 10–12 seconds — it can make cookies gummy.

Variations & Substitutions

Gluten-Free Version: Use a 1:1 gluten-free flour blend (such as Bob’s Red Mill) and add 1/2 tsp xanthan gum if not included. Baking time may increase by 1–3 minutes.
Vegan Version: Replace butter with 200 g (3/4 cup + 1 tbsp) vegan butter and use a flax “egg” (1 tbsp ground flax + 3 tbsp water per egg). Texture will be slightly softer and less rich.
Nutty Banana Chocolate Chip: Stir in 100 g (3/4 cup) toasted chopped walnuts or pecans. Toast nuts at 160°C (325°F) for 6–8 minutes until fragrant.
Double-Chocolate: Replace 50 g (1/2 cup) flour with 50 g (1/2 cup) unsweetened cocoa powder and increase chocolate to 250 g (1 1/2 cups). Baking time stays the same but watch for faster browning.
Lower-Sugar: Reduce granulated sugar to 25 g (2 tbsp) and use dark chocolate (at least 60% cacao) to keep balance; cookie will be less sweet and slightly denser.

Serving Suggestions & Pairings

Serve warm with a glass of cold milk or spiced coffee for contrast.
Top with a scoop of vanilla ice cream and a drizzle of caramel for an easy dessert.
Pair with a fruit-forward yogurt or a smoothie for brunch; see our creamy chocolate banana smoothie bowl for a matching flavor profile.

Frequently Asked Questions

Q: Why did my cookies turn out dry?
A: Most often you added too much flour. Measure by weight or spoon and level. Also avoid overbaking; remove when centers still look soft.

Q: Can I make this without eggs?
A: Yes. Use a flax egg for each egg (1 tbsp ground flax + 3 tbsp water, chilled 10 minutes). The texture will be a touch more cake-like and less chew.

Q: Can I double this recipe?
A: Yes. Double all ingredients and mix in a larger bowl. Bake on multiple sheets, leaving room for air to circulate. You may need to bake in batches; do not crowd the oven.

Q: Can I prepare this the night before?
A: Absolutely. Make the dough and chill it in the fridge overnight. Bring to scoopable firmness and bake as directed, adding 2–3 minutes to the bake time if very cold.

Q: How long does this keep in the fridge?
A: Baked cookies keep up to 4 days in an airtight container in the fridge. For longer storage, freeze up to 3 months.

Q: My cookies spread too much. What went wrong?
A: Dough was too warm or you used too much butter. Chill dough 15–30 minutes before baking and make sure the oven temperature is correct.

Q: Can I use quick oats in this recipe?
A: You can add up to 60 g (2/3 cup) quick oats by reducing flour by the same weight; cookies will be heartier and chewier.
