These banana cranberry cookies are soft in the middle, lightly crisp around the edges, and dotted with tart dried cranberries. Mashed banana adds moisture and flavor, while oats give the cookies a satisfying, chewy bite—no mixer or chilling required.
Ingredients
- 1 cup (125 g) all-purpose flour, spooned into the measuring cup and leveled
- 1 cup (90 g) old-fashioned rolled oats
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon fine salt
- 1/2 cup (113 g) unsalted butter, softened
- 1/2 cup (100 g) packed light brown sugar
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract
- 1/2 cup (about 120 g) mashed ripe banana, from 1 medium banana
- 3/4 cup (90 g) dried cranberries
- 1/2 cup (60 g) chopped walnuts or pecans, optional
Instructions
- Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper. Set a rack in the center of the oven. If you have only one sheet, bake in batches and let it cool before adding the next batch.
- In a medium bowl, whisk together the flour, oats, baking soda, cinnamon, and salt until evenly combined. Set aside.
- In a large bowl, beat the softened butter and brown sugar with a sturdy spoon or hand mixer until creamy and well blended, about 1–2 minutes. Beat in the egg and vanilla, then stir in the mashed banana. The mixture may look slightly curdled; that is normal.
- Add the dry ingredients to the banana mixture. Stir just until no dry flour remains. Fold in the cranberries and, if using, the chopped nuts. Avoid overmixing, which can make the cookies tougher.
- Scoop rounded tablespoons of dough onto the prepared sheets, leaving about 2 inches between each mound. The dough will be soft. Gently flatten each mound a little with damp fingers or the back of a spoon; these cookies spread less than many conventional cookies.
- Bake one sheet at a time for 11–14 minutes, until the edges look set and lightly golden. The centers may still seem soft, but they will firm as the cookies cool. Do not wait for the tops to brown deeply, or the cookies may dry out.
- Leave the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. This short rest helps the soft cookies set without breaking.
Tips
- Measure the banana: Use 1/2 cup mashed banana rather than adding a whole banana automatically. Extra banana makes the dough wetter and can leave the cookies cakey or gummy. A ripe banana with brown spots gives the best sweetness and flavor.
- Use room-temperature butter: It should give slightly when pressed but not look shiny or melted. Melted butter can make the dough greasy and alter the cookies’ texture.
- Adjust for your cranberries: Sweetened dried cranberries are common and work as written. If yours are especially tart, add 1–2 tablespoons more brown sugar; if they are very sweet, keep the recipe amount as is.
- Check the first batch: Ovens and banana moisture vary. Start checking at 11 minutes, and let a test cookie cool before judging its texture. For food safety, cookies containing egg should be fully baked; if checking with a thermometer, aim for at least 160°F (71°C) in the center.
Serving Suggestions
Serve the cookies slightly warm or at room temperature with coffee, tea, or a glass of milk. They make a handy breakfast-on-the-go or lunchbox snack, though their soft texture is best once fully cooled. For dessert, pair one with vanilla yogurt or a small scoop of vanilla ice cream. If serving a batch warm, allow the centers to set for at least 5 minutes first.
Variations
For a different mix-in, replace the walnuts with pecans, pumpkin seeds, or an equal amount of chocolate chips. A handful of white chocolate chips goes particularly well with the tart cranberries. You can substitute an equal amount of raisins or chopped dried cherries, keeping the total dried fruit to about 3/4 cup.
For a slightly heartier cookie, replace up to 1/2 cup of the all-purpose flour with whole-wheat flour; the result will be a little denser. To make the recipe gluten-free, use a measure-for-measure gluten-free flour blend and certified gluten-free oats. Check the blend’s instructions, as results vary. For a dairy-free version, use a firm plant-based butter substitute designed for baking. The cookies contain egg, so this recipe is not egg-free without further testing.
Storage and Reheating
Cool the cookies completely before storing so trapped steam does not make them soggy. Keep them in an airtight container at room temperature for up to 3 days. Because banana adds moisture, discard cookies that show mold or develop an unusual smell; do not leave them out for extended periods in a hot or humid kitchen.
For longer storage, freeze the cooled cookies in a freezer-safe container or bag, with parchment between layers, for up to 2 months for best quality. Thaw at room temperature for about 30–60 minutes. To warm, microwave one cookie for 8–12 seconds, or heat several on a baking sheet at 300°F (150°C) for about 5 minutes. Reheat only what you plan to eat, and avoid repeated warming and cooling.
Frequently Asked Questions
Can I use fresh cranberries?
Yes, but they are much more tart and contain more moisture than dried cranberries. Chop them coarsely and use about 3/4 cup, then add 1–2 tablespoons of brown sugar if you like a sweeter cookie. Expect a slightly wetter, tangier result; dried cranberries give the most consistent texture.
Why are my cookies too soft or cakey?
The most common cause is too much banana or underbaking. Measure the mashed banana, level the flour rather than packing it, and bake until the edges are set. The centers remain tender, so let the cookies cool on the sheet before deciding they need more time.
Can I make the dough ahead?
You can cover the dough and refrigerate it for up to 24 hours. It will firm up, so let it sit at room temperature for about 10–15 minutes before scooping. The cookies may need an extra minute or two in the oven; use the visual cues rather than the clock alone.
Can I freeze the dough?
Yes. Scoop the dough onto a lined tray and freeze until firm, then transfer the portions to a freezer-safe bag for up to 2 months. Bake from frozen at 350°F (175°C), adding about 2–4 minutes and checking that the edges are set. Do not thaw the dough at room temperature for several hours.
Are these cookies gluten-free?
Not as written: all-purpose flour and ordinary oats may contain gluten or be cross-contaminated. Use a certified gluten-free measure-for-measure flour blend and certified gluten-free oats, and check that the dried cranberries and other additions are also labeled gluten-free.
How many cookies does the recipe make?
It makes about 22–24 cookies when portioned with rounded tablespoons. Larger scoops will yield fewer cookies and may need a few extra minutes to bake. Keep the portions similar in size so they finish at the same time.
