We’ve all been there. The bananas on the counter have gone from bright yellow to a spotty, freckled brown. The guilt sets in. “I should make banana bread,” you think. But who has the time for an hour of baking? Enter these cookies. They are the answer to the overripe banana dilemma, and they are faster, easier, and more portable than any loaf.
This recipe is my most-made, most-shared, most-requested one for a reason. It’s essentially a blender batter, which means it comes together in about five minutes flat. They bake up soft, cakey, and taste like the very best part of banana bread—the top crust—in every single bite. This is the recipe I email to new neighbors and text to new moms. It’s a little piece of comfort, no fork required.

Why You’ll Love This Recipe
- It’s a 5-minute blender batter. Seriously, you just dump everything in and blend. The ultimate in easy cleanup.
- It uses up those sad bananas. No more food waste guilt!
- They’re naturally sweet. The bananas do all the heavy lifting, with just a little help from maple syrup.
- The texture is like a soft, pillowy muffin top. And let’s be honest, the muffin top is the best part.
Grab These
- 2 cups old-fashioned rolled oats
- 2 very ripe medium bananas
- 2 large eggs
- ⅓ cup pure maple syrup
- 1 tsp vanilla extract
- 1 tsp baking powder
- ½ tsp ground cinnamon
- ¼ tsp fine sea salt
- ½ cup mix-ins: My classic is ½ cup chopped walnuts, but chocolate chips are never a wrong choice.
Let’s Make It
Fire up your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Okay, here’s the magic. Grab your blender. I use my trusty Oster that’s seen better days, but any blender or food processor will work. Put all of the ingredients except for your mix-ins into the blender. Yes, everything: the oats, bananas, eggs, maple syrup, vanilla, baking powder, cinnamon, and salt.
Now, put the lid on and blend! Start on low and work up to high. You’re going to blend for about 30-45 seconds, stopping to scrape down the sides if you need to. You want a smooth, relatively uniform batter. It will be thick, but pourable.
Pour the batter into a bowl and stir in your walnuts or other mix-ins by hand. This batter is much wetter than the others, so don’t be alarmed. Using a large cookie scoop or a 1/4 cup measure, scoop the batter onto your prepared baking sheet. These need room to spread a little, so leave a couple of inches between them.
Bake for 14-16 minutes, until the tops are set and spring back lightly when touched, and the edges are a beautiful golden brown. Let them cool on the sheet for 5 minutes before moving them to a rack. They are divine warm, almost like a mini pancake in cookie form.

Variations & Add-Ins
- Banana Chocolate Chip: A no-brainer. Swap the walnuts for 1/2 cup of semi-sweet chocolate chips.
- Blueberry Lemon: Fold in 1/2 cup of fresh or frozen blueberries and the zest of one lemon. So bright and fresh.
- Tropical Bliss: Add 1/4 cup of shredded coconut and 1/4 cup of chopped dried pineapple along with the macadamia nuts.
Serving Ideas
I love these warm with a little pat of salted butter melting into the top. Pure bliss. They’re also fantastic packed into a lunchbox, as they stay soft and delicious for hours.
Storage & Reheating
Store these in an airtight container in the fridge for up to 5 days. They are very moist, so the fridge keeps them fresh. You can also freeze them for up to 3 months. To reheat, just pop one in the toaster oven for a few minutes—it brings back that fresh-baked texture perfectly.
My Two Cents (Pro-Tip)
Don’t over-blend! You just want to break down the oats enough to create a cohesive batter. If you blend it into a completely smooth paste, the cookies can become a little gummy. A little texture from the oats is a good thing.
You Asked, I’m Answering (FAQ)
“Can I make these without a blender?”
You can! Just mash the bananas very well in a bowl first, then whisk in the wet ingredients. In a separate bowl, mix the dry ingredients (oats, baking powder, cinnamon, salt). Combine wet and dry, then fold in your mix-ins. The texture will be a bit more rustic and oaty, but still delicious.
“Why did my cookies turn out flat?”
This usually means your baking powder might be old. Test it by stirring half a teaspoon into a cup of hot water. If it doesn’t fizz up vigorously, it’s time for a new can.
