Easy Banana Bread Cookies Recipe for Dinner Tonight

Banana bread cookies give you everything I love about a soft loaf in grab-and-go cookie form. Overripe bananas go straight into the dough instead of the bin. These banana bread cookies bake in 12 minutes and come out soft, chewy, and lightly sweet.

Why These Banana Bread Cookies Work

Mashed ripe banana replaces some of the fat and adds natural sweetness. The dough stays soft after baking because banana holds moisture. You get the tender crumb of banana bread in a flat, portable shape.

Brown sugar deepens the flavor with a caramel-molasses note that white sugar alone cannot match. Combined with melted butter and mashed banana, the dough spreads just enough in the oven to give you a chewy center and golden edges.

One egg yolk (no white) keeps these banana bread cookies dense and fudgy. A whole egg would add too much structure and dry the crumb. The yolk-only technique is a small change with a big texture payoff.

Ingredients

• 1 cup (225g / 8 oz) unsalted butter, melted and cooled
• 1 cup (200g / 7 oz) brown sugar, packed
• 3/4 cup (170g / 6 oz) mashed ripe banana (about 2 medium bananas)
• 2 teaspoons vanilla extract
• 1 large egg yolk
• 2 and 1/3 cups (290g / 10.2 oz) all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon cinnamon
• 1/4 teaspoon salt
• 1 cup (170g / 6 oz) chocolate chips

What You Need for Banana Bread Cookies

Ripe banana — the riper the better. Black-spotted bananas are sweeter and mash smoothly. Under-ripe bananas do not mash well and leave lumps in the dough.

Melted butter — melted butter gives a chewier cookie than creamed butter. Let it cool to room temperature before adding the eggs so you do not accidentally cook the yolk.

Brown sugar — packed brown sugar adds moisture and a deep caramel flavor. Light or dark brown sugar both work; dark brown gives a more pronounced molasses note.

Egg yolk only — the yolk adds richness and binds the dough without the drying effect of the white. Save the white for an omelet the next morning.

Baking soda — reacts with the banana’s natural acidity to give a slight lift. The cookies still spread flat but come out with a tender, open crumb.

Chocolate chips — semi-sweet works best against the sweet banana base. You can swap for walnuts, pecans, or dried cranberries.

How to Make Banana Bread Cookies

1. Preheat the oven to 325°F (163°C). Line two baking sheets with parchment paper.
2. Whisk melted butter, brown sugar, mashed banana, and vanilla extract in a large bowl until smooth.
3. Add the egg yolk. Whisk until fully incorporated.
4. Add flour, baking soda, cinnamon, and salt. Stir with a spatula until just combined — do not overmix.
5. Fold in chocolate chips.
6. Scoop the dough into 1.5-tablespoon balls. Place 2 inches (5cm) apart on the prepared baking sheets.
7. Bake for 11 to 13 minutes until the edges are set and golden. The centers will look slightly underdone.
8. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. They firm up as they cool.

Banana Bread Cookie Variations

Peanut Butter Banana Bread Cookies

Swap 1/4 cup of the butter for 1/4 cup of creamy peanut butter. The peanut butter flavor works naturally against the banana and chocolate chips. These hold their shape slightly better than the original.

Banana Bread Cookies with Walnuts

Replace the chocolate chips with 1 cup of roughly chopped walnuts. The nutty crunch contrasts with the soft banana dough. This version leans closer to classic banana bread flavor without the chocolate.

Oatmeal Banana Bread Cookies

Swap 1/2 cup of the all-purpose flour for 1/2 cup of rolled oats. The oats add chew and a slightly nutty flavor. These spread less than the original and come out thicker with more toothsome texture.

Banana Bread Cookies with Cream Cheese Frosting

Beat 4 oz (113g) softened cream cheese with 1 cup powdered sugar and 1 teaspoon vanilla. Spread a thin layer over cooled cookies. This turns a casual snack into a dessert-worthy bite.

Tips for the Best Banana Bread Cookies

• I always use black-spotted bananas — the natural sugar content is highest and the mash is silky smooth.
• Cool the melted butter completely before mixing or the dough will spread too thin in the oven.
• Pull the cookies out when the centers look underdone — they set fully as they cool on the hot pan.
• Chill the dough for 30 minutes if your kitchen is warm — this prevents excess spreading.
• Press a few extra chocolate chips on top of each ball before baking for a bakery-style look.
• Store cooled cookies in an airtight container at room temperature for up to 5 days.

Make Ahead & Storage

Banana bread cookie dough keeps in the fridge for up to 3 days covered tightly. Scoop and bake directly from the fridge — add 1 to 2 minutes to the bake time for cold dough.

To freeze unbaked dough, scoop into balls and freeze on a parchment-lined tray for 1 hour. Transfer to a zip-lock bag and freeze for up to 3 months. Bake from frozen at 325°F (163°C) for 14 to 15 minutes.

Baked cookies freeze well too. Stack in an airtight container with parchment between layers and freeze for up to 2 months. Thaw at room temperature for 20 minutes or microwave for 15 seconds.

Common Questions

How ripe should the bananas be for banana bread cookies?

The riper the better. Black-spotted or fully black bananas have the most sugar and the most banana flavor. A barely yellow banana will produce a blander, starchier cookie with less natural sweetness.

Why are my banana bread cookies spreading too much?

The most common cause is warm butter. If the melted butter was added hot, it will cause excessive spread. Cool the butter to room temperature and chill the dough for 30 minutes before scooping. Also check that your baking soda is fresh.

Can I make banana bread cookies without chocolate chips?

Yes. Leave them out entirely for a plain banana cookie, or swap in walnuts, pecans, white chocolate chips, or dried fruit. The dough is flexible — the banana flavor carries without any mix-ins.

Can I use a whole egg instead of just the yolk?

You can, but the cookies will be less chewy and slightly drier. The egg white adds structure that works against the soft, fudgy texture. Stick to the yolk if you have it — save the white for another use.
