These baked banana donuts yield 12 tender, moist rings infused with ripe banana and a touch of cinnamon. Mash bananas and whisk with milk, melted butter, eggs and vanilla, then fold in flour, sugar, baking powder and baking soda until just combined. Pipe into a greased donut pan and bake at 350°F (180°C) for 14–16 minutes. Cool slightly, dust with powdered sugar or glaze, and serve warm.
My daughter walked into the kitchen one Saturday morning holding two bananas so brown they looked ready for the trash, and she said dad can we make donuts with these. I had never made a donut in my life, but her confidence in me was flattering enough to try. We pulled up a basic baked donut recipe, mashed those sad bananas into something beautiful, and by noon the whole house smelled like a bakery had collided with a tropical fruit stand.
That first batch disappeared before the second tray even came out of the oven. My wife stood at the counter eating them bare, no glaze, no sugar dust, just warm banana bread in donut form, and she looked at me like I had invented something. I had not invented anything, but I have never corrected her.
Ingredients
- 2 ripe bananas, mashed: The browner the peel, the sweeter and softer the mash, so do not be afraid of spots.
- 1/2 cup milk: Whole milk gives the best texture but any milk you have will work fine.
- 1/4 cup unsalted butter, melted: Melted butter keeps things rich without needing to soften it ahead of time.
- 2 large eggs: They bind everything together and add structure so the donuts hold their shape.
- 1 teaspoon vanilla extract: A quiet background note that rounds out the banana flavor beautifully.
- 2 cups all-purpose flour: Spoon and level it gently because packed flour makes dense donuts.
- 2/3 cup granulated sugar: Not too sweet on its own but perfect once you add the cinnamon sugar dusting.
- 2 teaspoons baking powder: This is what gives baked donuts their gentle rise and soft crumb.
- 1/2 teaspoon baking soda: Works alongside the acidity of the bananas for extra lift.
- 1/2 teaspoon salt: Just enough to keep the sweetness honest and balanced.
- 1/2 teaspoon ground cinnamon: Warm spice that pairs naturally with banana and makes the kitchen smell incredible.
- Powdered sugar and cinnamon for dusting: Entirely optional but a quick shake transforms them into something special.
Instructions
- Preheat and prepare the pan:
- Set your oven to 350 degrees F and grease a donut pan with butter or nonstick spray so nothing sticks later.
- Mash and mix the wet ingredients:
- In a large bowl, mash the bananas until nearly smooth, then pour in the milk, melted butter, eggs, and vanilla, whisking until everything is well combined and slightly frothy.
- Combine the dry ingredients:
- In a separate bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon so the leavening and spice are evenly distributed before meeting the wet mixture.
- Bring it all together:
- Pour the dry ingredients into the wet and fold gently with a spatula just until you no longer see dry flour streaks, because overmixing is the fastest path to rubbery donuts.
- Pipe the batter:
- Spoon the batter into a piping bag or a zip-top bag with one corner snipped off, then pipe evenly into each donut cavity, filling about three quarters full to leave room for rising.
- Bake until golden:
- Slide the pan into the oven and bake for 14 to 16 minutes until the tops are lightly golden and a toothpick inserted into the thickest part comes out clean.
- Cool briefly:
- Let the donuts rest in the pan for 5 minutes so they firm up slightly, then gently turn them out onto a wire rack to finish cooling.
- Dust and serve:
- While still slightly warm, shake a mixture of powdered sugar and cinnamon over the tops using a small sieve for an even, snow-like coating.
The second time I made these, I brought a plate to our neighbor Helen, who watches our dog when we travel. She called that evening to say she ate all three donuts standing at her kitchen counter and did not save one for her husband.
What to Know About the Tools
A donut pan is the one piece of equipment you truly need here, and it is worth the small investment if you see yourself making these even twice a year. If you do not have one, you can bake the batter in a mini muffin tin and call them banana bites, though the shape will not be as fun.
Keeping Them Fresh
These are at their absolute best within a few hours of baking, when the edges are still slightly soft and the cinnamon sugar has not yet melted into the surface. If you must store them, an airtight container at room temperature will keep them decent for up to two days, but the texture will shift toward denser and more muffin-like.
Making Them Your Own
The base recipe is endlessly forgiving and loves additions. Fold in a handful of mini chocolate chips or toasted walnuts right at the end of mixing if you want to dress them up.
- A simple glaze made from powdered sugar and a splash of milk turns them into something closer to a bakery showcase donut.
- Try a pinch of nutmeg alongside the cinnamon for a slightly warmer, more complex spice profile.
- Always let them cool just a little before dusting or glazing because the heat will melt your toppings right off.
Every time I see bananas going dark on the counter now, I feel a little spark of possibility instead of guilt. My daughter still asks for donuts every weekend, and I have stopped pretending I invented them.
Recipe FAQs
- → How ripe should the bananas be?
-
Use very ripe bananas with brown spots for the best sweetness and flavor. They mash easily and add moisture, helping the donuts stay tender.
- → Can I substitute oil for butter?
-
Yes—use a neutral oil (like vegetable or canola) in equal volume to the melted butter. Oil will produce a slightly softer, moister crumb.
- → Is piping the batter necessary?
-
Piping helps fill donut cavities evenly and keeps tops neat, but you can spoon batter into the pan; just smooth the tops to promote even baking.
- → How do I avoid dense donuts?
-
Do not overmix once dry ingredients are added. Measure flour properly and fold until just combined to keep the texture light and tender.
- → How should I store and reheat them?
-
Store in an airtight container at room temperature for up to 2 days. Reheat briefly in a low oven or microwave for a few seconds to revive softness.
- → Can these be frozen?
-
Yes—freeze cooled donuts in a single layer on a sheet pan, then transfer to a sealed bag. Thaw at room temperature and warm briefly before serving.
