This banana cake donut recipe transforms ordinary cake batter into irresistible, two-bite treats with a caramelized glaze that melts at the first bite. The secret lies in using ripe bananas and a simple yeast-free batter that fries into golden, tender donuts—no yeast or long rises required. I perfected this method after testing countless variations, and the result is a donut that’s light yet rich, with a texture that’s impossible to resist.
The beauty of this recipe is its foolproof technique—just mix, fry, and glaze. You’ll need a deep fryer (or a heavy pot with oil) and a thermometer to maintain the perfect 350°F temperature for even cooking. The batter comes together in minutes, and the glazing adds that signature caramelized finish that makes these donuts taste like a bakery secret. Whether you’re baking for a crowd or treating yourself to a weekend breakfast, these donuts deliver every time.
What sets these apart is the caramelized frosting, which adds a sweet, buttery crunch that contrasts perfectly with the soft cake interior. The frosting is quick to make and elevates the donuts from homemade to restaurant-quality in seconds. No special tools are needed—just a few pantry staples and a little patience for the frying process.
Serve them warm with a cup of coffee or save a few for later—they’re just as good the next day (if they last that long). This recipe is perfect for brunch, dessert, or even a sweet snack. Let’s get started on creating your own batch of these indulgent, banana-infused donuts!
Ingredients for banana cake donut
Twelve simple ingredients transform ripe bananas into golden, caramelized donuts with restaurant-quality glaze.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 whole | Very ripe, with brown spots |
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Baking Powder 🍃 | 1 tbsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Vegetable Oil 🫒 | 1 cup | For frying, high smoke point |
| Powdered Sugar 🍚 | 2 cups | For caramelized glaze |
| Heavy Cream 🥛 | ¼ cup | For glaze, full-fat |
| Cinnamon 🌶️ | ½ tsp | Ground, for glaze |
The bananas are non-negotiable here—blackened, squishy spots mean maximum sweetness. Trader Joe's and Whole Foods usually have the ripest selection, but check your local grocery's produce section first. For the flour, King Arthur is my go-to—it's finely milled and gives the best texture. The baking powder matters too: Diamond Crystal has more lift than aluminum-free brands. Store your baking powder in an airtight container to keep it fresh; it loses potency after about 6 months.
No ripe bananas? Frozen bananas work in a pinch—thaw and drain excess liquid. Out of powdered sugar? Granulated sugar blended into a fine powder works, but it won't be as smooth. The glaze can be made ahead and reheated gently—just add a splash of milk to thin it if needed. For extra richness, swap half the heavy cream for whipped cream. And if you're feeling fancy, add a pinch of espresso powder to the glaze for depth. The donuts freeze beautifully too—just glaze them after baking and before freezing.
Keep your batter in the fridge for up to 2 days—it actually improves as it rests. The glaze will thicken when chilled, so thin with a splash of milk before using. These donuts reheat best in a 350°F oven for 2-3 minutes—just until the glaze melts. For a crowd, fry in batches and glaze as you go. Store glazed donuts in an airtight container for 3 days, though they'll likely disappear faster than that.

Step-by-step instructions for banana cake donuts
Here's how to make these tender, bite-sized donuts with a caramelized glaze—quickly and perfectly.
Prepare the Banana Cake Batter
In a large mixing bowl, mash the 2 whole ripe bananas until completely smooth—no lumps should remain. This ensures even distribution throughout the batter. Stir in the 1 cup granulated sugar and 1 tsp vanilla extract until fully combined. The mixture should be thick but pourable.
In a separate bowl, whisk together the 3 cups all-purpose flour, 1 tbsp baking powder, and 0.5 tsp salt. Sift the dry ingredients directly into the banana mixture to avoid clumps. Gently fold in the 0.5 cup melted unsalted butter and 1 cup vegetable oil using a spatula until just combined. Overmixing develops gluten, which makes the donuts tough.
Finally, add the 2 whole large eggs, one at a time, mixing gently after each addition. The batter should be thick but still spreadable—like a rich cake batter. If it seems too stiff, add 1-2 tablespoons of milk (though the recipe doesn’t call for it, this is a quick fix). Cover the bowl and let the batter rest for 15 minutes at room temperature. This step relaxes the gluten for a lighter texture.
Fry the Donuts to Golden Perfection
Heat 2 inches of vegetable oil in a deep skillet or Dutch oven to 350°F. Use a candy or deep-fry thermometer to monitor the temperature—it’s critical for even cooking. Drop 1-tablespoon portions of batter into the oil, spacing them 2 inches apart to prevent sticking. Fry in batches to avoid overcrowding, which lowers the oil temperature.
Cook the donuts for 2-3 minutes per side, until they’re golden brown and a toothpick inserted in the center comes out clean. They’ll puff slightly as they fry, so don’t press them down. Use a slotted spoon to transfer them to a wire rack or paper towel-lined plate to drain excess oil. Work quickly—donuts lose heat fast once removed from the oil.
Here’s the thing—if the oil smokes excessively, reduce the heat slightly. Smoky oil makes the donuts bitter, and you want that sweet, caramelized flavor to shine. Keep the oil at 350°F for consistent results every time.
Make the Caramelized Glaze
While the donuts fry, combine the 2 cups powdered sugar, 0.25 cup heavy cream, and 0.5 tsp cinnamon in a medium saucepan. Cook over medium-low heat, stirring constantly with a silicone spatula, until the mixture thickens to a spreadable consistency—about 3-4 minutes. The glaze should coat the back of the spoon smoothly but not be runny.
Remove the pan from heat and let the glaze cool slightly for 2 minutes. It’ll thicken further as it sits. If it’s too stiff, add 1 teaspoon of milk to loosen it. The glaze should be glossy and pourable but not drippy. This balance ensures it clings to the donuts without sliding off.
Dip and Serve Immediately
Dip each donut halfway into the glaze, letting any excess drip off back into the saucepan. Place them on a wire rack set over parchment paper to set for 5-10 minutes. This step is crucial—the glaze needs time to firm up slightly so it doesn’t make the donuts soggy.
Serve the donuts warm for the best texture. The glaze will be slightly tacky at first but will set into a smooth, caramelized coating as it cools. Pair them with a cup of coffee or tea for a quick, satisfying breakfast or dessert. These donuts keep well in an airtight container for 2 days, though they’re best enjoyed fresh.
Pro Tips For Making Banana Cake Donut
- Mash Bananas First: I learned this the hard way—skip the "add them whole" step. Mash the bananas until smooth (no lumps!) before mixing with wet ingredients. That extra 30 seconds of mashing guarantees a tender crumb instead of a chewy surprise.
- Use Room-Temp Eggs: Cold eggs make the batter fight you. Let eggs sit out for 20 minutes before cracking them into the butter-sugar mix. The batter will come together faster and the donuts will rise better—no one wants a dense, sad ring.
- Fry at 350°F: Too hot? They’ll burn outside before cooking through. Too cool? They’ll absorb oil like a sponge. Stick to 350°F and fry in batches—crowding the pan drops the temperature and ruins the texture. Patience here pays off.
- Add Cinnamon to Dry Mix: Sounds weird, but it works: fold 1 teaspoon of cinnamon into the flour before mixing. The flavor gets evenly distributed instead of settling at the bottom of the pan. (Yes, even if your recipe doesn’t list it—trust me.)
Serving suggestions for this recipe
Morning Coffee Pairing
These banana cake donuts are a match made in heaven with a hot cup of coffee—the bitterness cuts through the sweetness beautifully. I recommend a medium-roast coffee like Starbucks Pike Place or Blue Bottle for its balanced acidity. For a cozy twist, try a cinnamon latte with vanilla syrup to echo the flavors in the glaze. The warmth of the coffee enhances the caramelized frosting, making each bite feel like a bakery treat. ☕
Iced Tea Contrast
For a refreshing alternative, serve these donuts with sweet iced tea—the cool liquid contrasts perfectly with the warm, gooey glaze. A Southern-style sweet tea (brewed with 1/4 cup sugar per quart) works wonderfully, or try a peach iced tea for a fruity complement. The acidity in the tea helps balance the richness of the donuts, especially if you're serving them at a brunch or outdoor gathering. 🍹
Whipped Cream Topping
Add a dollop of homemade whipped cream to elevate your donuts to next-level indulgence. Whip 1 cup heavy cream with 1 tablespoon powdered sugar until soft peaks form, then pipe or spoon onto the glazed donuts. For extra flair, dust with cinnamon or a pinch of nutmeg. This topping adds a light, airy contrast to the dense cake and caramelized glaze—perfect for special occasions. 🍦
Chocolate Dip Station
Set up a chocolate dip station for guests to customize their donuts. Melt 8 oz dark chocolate with 2 tablespoons heavy cream over double boiler, then let cool slightly. Serve with mini marshmallows, crushed nuts, or sprinkles for dipping. The dark chocolate pairs beautifully with the banana and caramel, creating a decadent flavor combination. This interactive element makes serving fun for parties or family gatherings. 🍫
Seasonal Fruit Pairings
In warmer months, add fresh berries like strawberries or blueberries to your serving platter. The tartness of the fruit balances the sweetness of the donuts, especially when paired with a lemon glaze (add 1 teaspoon lemon juice to the glaze). For winter, try sliced apples or pears with a sprinkle of cinnamon—the warm spices complement the donut flavors perfectly. 🍓
Make-Ahead Serving Tips
If serving a crowd, prepare the donuts ahead and store them in an airtight container at room temperature for up to 2 days. Reheat glazed donuts in a 350°F oven for 2-3 minutes to restore the glaze’s shine. For a buffet-style setup, arrange donuts on a tiered tray with small bowls of extra glaze, whipped cream, and fruit for guests to customize their treats. This keeps everything fresh and inviting. ✨

Frequently asked questions
Can I make these donuts without frying?
For a baked version, preheat your oven to 375°F and line a baking sheet with parchment paper. Drop 1-tablespoon portions of batter onto the sheet, spacing them 2 inches apart. Bake for 12-15 minutes until golden. The texture will be slightly denser than fried donuts, but still delicious. Brush with melted butter while warm for extra richness.
How do I know when the oil is ready for frying?
Use a candy or deep-fry thermometer to check the oil temperature—it should be at 350°F. If you don’t have a thermometer, test with a small piece of batter: it should sizzle vigorously and float to the surface within 10 seconds. If it browns too slowly, the oil needs to heat up more. Never let the oil smoke excessively, as this can make the donuts bitter.
Can I use frozen bananas instead of fresh?
Yes, but thaw them first and drain any excess liquid. Frozen bananas work well in a pinch, though they may make the batter slightly watery. If needed, add 1-2 extra tablespoons of flour to thicken it. The texture will be slightly different but still delicious—just expect a denser donut.
Why did my donuts turn out dense?
Overmixing the batter or using cold ingredients can make donuts dense. Always mix gently and let the batter rest for 15 minutes before frying. Also, ensure your oil is at 350°F—too low a temperature causes uneven cooking. For extra lightness, sift your flour and use ripe bananas with plenty of brown spots.
How can I make the glaze extra shiny?
For a glossier finish, add 1 teaspoon of lemon juice or 1 tablespoon of corn syrup to the glaze while heating. Stir well and cook until fully combined. Let the glaze cool slightly before dipping—this helps it set into a smooth, mirror-like coating. If it’s too thick, thin with 1 teaspoon of milk at a time.
