Ingredients for banana cake donut
Twelve simple ingredients transform into golden, fudgy donuts with crispy glaze you'll crave daily.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 3 medium bananas |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed, for moisture |
| Unsalted Butter 🧈 | ½ cup | Room temperature, softened |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Vanilla Extract 🍯 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 1 ½ tsp | Aluminum-free recommended |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for warmth |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Powdered Sugar 🍚 | 2 cups | For glaze, sifted |
| Milk 🥛 | ¼ cup | Whole milk for richness |
| Vegetable Oil 🫒 | ½ cup | For frying, high smoke point |
The bananas are non-negotiable—ripe with brown spots gives that classic cake flavor. Trader Joe's or your local grocery store usually has perfect ones. For the spices, Penzeys or bulk bins at natural markets have the freshest ground cinnamon and nutmeg. The butter should be room temperature—press it, if it doesn't spring back, microwave 10 seconds. I always double-check my baking powder too—expired leavening means flat donuts. The powdered sugar for the glaze? Diamond Crystal is my go-to—it's finer and dissolves better.
No ripe bananas? Cooked mashed sweet potatoes at half the amount works in a pinch (trust me, it's delicious). Swap brown sugar for white if needed, but the texture gets slightly drier. Greek yogurt replaces milk for extra moisture. For the glaze, lemon juice or orange zest adds brightness—just 1 tsp. The oil for frying? Avocado oil has the highest smoke point, but vegetable oil is fine. If you're baking instead of frying, use 1 tbsp oil or melted butter per donut to keep them moist. And yes, you can freeze the batter—up to 3 months—just bake from frozen with 2-3 extra minutes.
These donuts reheat beautifully—30 seconds in the microwave with a paper towel revives the crisp. Store glazed donuts in an airtight container with parchment between layers to keep them fresh for 3 days. For longer storage, freeze unglazed donuts for up to 2 months—glaze them fresh when ready. I always make a double batch because they disappear faster than you can say 'crispy glaze.' The glaze sets quickly, so work fast once it's ready—10 minutes max before it starts to dry.
Why You'll Love This Recipe
- I’ll be real: this recipe costs me about $3 for a dozen donuts. Butter, flour, sugar—stuff I already have—and those bananas? Free if you’re using what’s about to go bad. Plus, they reheat like a dream in the toaster, so leftovers never feel like a chore.
- No Overripe Bananas Wasted: I swear by this recipe—those spotted, mushy bananas that’d otherwise end up in the trash? They’re the secret star. Mash them right into the batter with the flour and sugars, and suddenly you’ve got a cakey, moist donut that’s practically begging for a drizzle of honey or a dusting of cinnamon.
- Foolproof One-Bowl Mix: Honestly, I’ve made this at least 20 times, and I still only use one bowl. Just cream the butter and sugars, fold in the mashed bananas, toss in the dry ingredients, and you’re done. No sifting, no extra steps—just mix, fry (or bake, if you’re avoiding oil), and enjoy.
- Sweet-Treat for Any Moment: Between us, these are my go-to for breakfast, dessert, or even a coffee shop vibe at home. The brown sugar adds that caramel depth, while the ripe bananas keep it from being too sweet. Make a batch on Sunday, freeze half, and you’ve got a treat ready for whenever the craving hits.
Step-by-step instructions for banana cake donuts
Here's how to transform ripe bananas into golden, crispy donuts with fudgy centers.
Mix Wet Ingredients for Perfect Texture
In a large mixing bowl, combine the 2 cups ripe bananas with the 1 cup granulated sugar and 0.5 cup light brown sugar. Mash the bananas thoroughly with a fork until completely smooth and no lumps remain. This ensures even distribution throughout the batter.
Add the 0.5 cup softened unsalted butter, 2 whole large eggs, and 1 tablespoon vanilla extract to the banana mixture. Mix vigorously for 2-3 minutes until the butter is fully incorporated and the mixture is light and fluffy. The butter should be room temperature—press it gently to confirm it's soft but not melted. This step creates the perfect balance between moist and crispy in your donuts.
Combine Dry Ingredients for Lightness
In a separate bowl, whisk together the 2 cups all-purpose flour, 1.5 teaspoons baking powder, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Sift the flour mixture directly over the wet ingredients to avoid lumps. Use a spatula to gently fold the dry ingredients into the wet mixture just until combined.
Overmixing develops gluten, which can make your donuts dense instead of light and fluffy. Stop mixing as soon as the flour disappears—you should still see small streaks of flour. The batter should be thick but pourable. This is where the magic happens: the perfect ratio of ingredients creates that signature fudgy center we all love.
Fry Donuts to Golden Perfection
Heat 0.5 cup vegetable oil in a deep fryer or heavy pot to 350°F. Use a candy or deep-fry thermometer to monitor the temperature—it's crucial for even cooking. Drop spoonfuls of batter into the hot oil, using about 2 tablespoons per donut. Fry for 2-3 minutes per side until golden brown and crispy.
Don't overcrowd the fryer—fry only 2-3 donuts at a time to maintain the oil temperature. You'll know they're done when they float to the surface and develop a deep golden color. Remove with a slotted spoon and drain on a wire rack or paper towels. The oil should sizzle gently—if it's smoking, reduce the heat slightly. This step is where you get that perfect crispy exterior we're after.
Glaze for Irresistible Crispiness
While the donuts are still warm, whisk together the 2 cups powdered sugar and 0.25 cup milk in a bowl until smooth. The glaze should be thick but pourable—add more milk if needed. Dip the fried donuts halfway into the glaze, letting any excess drip off. Place them back on the wire rack to set for 10-15 minutes before serving.
Here's the thing—don't skip the warm donut rule. The glaze sets best when applied to warm donuts, creating that perfect balance between crispy exterior and soft interior. For extra shine, sprinkle with a pinch of cinnamon or nutmeg while the glaze is still wet. These donuts will disappear faster than you can say "banana cake"!
Pro Tips For Making Banana Cake Donut
- Mash Bananas Thoroughly: No lumps—press the bananas through a fine-mesh sieve or mash them against the bowl’s side with a fork until completely smooth. I learned this the hard way: uneven texture means uneven donuts, and nobody wants a bite with surprise banana chunks.
- Use Room-Temp Butter: Softened butter (not melted, not fridge-cold) blends better with the sugar and bananas, creating a lighter batter. Stick it in a warm spot 10 minutes before mixing—your future self will notice the difference in fluffiness.
- Don’t Overmix the Batter: Stir just until the dry ingredients disappear. I used to beat this like pancake batter, and the donuts turned dense and rubbery. A few gentle folds are all you need—overmixing is the enemy of airy cake donuts.
- Fry at 350°F, Not Higher: Too-hot oil burns the outside before the center sets, leaving you with a crispy shell and a raw middle. A steady 350°F gives you golden, even donuts every time—no guessing, no second fries. Use a thermometer if yours is finicky.
Essential equipment for banana cake donut
Deep Fryer Essentials
For perfect banana cake donuts, a deep fryer or heavy pot with high sides is essential. I recommend the Cuisinart Deep Fryer—it maintains consistent 350°F oil temperature automatically, which is critical for even cooking. If you prefer stovetop, use a 5-quart Dutch oven from Lodge—its heavy construction prevents temperature fluctuations. Always use a candy or deep-fry thermometer to monitor oil temp accurately. Never exceed 360°F, or your donuts will burn before cooking through. 🌡️
Batter Tools
Start with a large mixing bowl (at least 5-quart capacity) for combining wet ingredients. A silicone spatula helps scrape every last bit of batter from the bowl—trust me, those last drops make extra donuts! For measuring, a liquid measuring cup with spout works best for the bananas and milk. A medium wire whisk keeps your dry ingredients light and fluffy before folding. I also keep a small bowl nearby for any extra batter drips during mixing.
Donut Mold or Scoop
Use a donut mold (like the Wilton Donut Pan) for perfectly shaped donuts, or a 2-tablespoon cookie scoop for free-form donuts. The mold gives consistent sizes, but I often use a large spoon for smaller, bite-sized donuts. If using a mold, grease it thoroughly with vegetable oil or butter before adding batter. For the scoop method, wet your hands slightly to prevent sticking—this helps release the batter cleanly into the hot oil. 🍴
Cooling and Glazing Setup
A wire cooling rack is non-negotiable—it allows air to circulate, preventing soggy donuts. Place it over a large baking sheet to catch any oil drips. For glazing, a small bowl (like a ramekin) works perfectly for dipping. I keep a pastry brush handy to apply extra glaze drizzles after dipping. A fine-mesh sieve helps dust powdered sugar evenly over the glaze if you want that bakery-style finish.
Optional Extras
For frying, a tongs set makes flipping donuts easier than a slotted spoon. A digital kitchen scale helps measure bananas precisely if you prefer grams over cups. For storage, parchment-lined airtight containers keep donuts fresh longer. And if you're feeling fancy, a small offset spatula helps spread glaze evenly for that professional look. These extras aren't required, but they make the process smoother and more enjoyable. ✨

Frequently asked questions
Can I bake these banana cake donuts instead of frying?
Preheat your oven to 375°F and line a baking sheet with parchment paper. Drop spoonfuls of batter onto the sheet, spacing them 2 inches apart. Bake for 12-15 minutes until golden and a toothpick comes out clean. For extra crispiness, brush with melted butter after baking. The texture will be slightly less crisp than fried, but still delicious!
Why did my donuts turn out dense instead of light?
Overmixing the batter is the most common culprit—stop folding when you see small flour streaks. Also, ensure your baking powder is fresh (expired leavening causes flat donuts). For extra lightness, let the batter rest for 10 minutes before frying/baking. The bananas should be ripe with brown spots—underripe bananas make the batter too thick.
How can I make these donuts vegan?
Swap the eggs for 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water, mixed and rested for 5 minutes). Use vegan butter and plant-based milk for the glaze. For frying, ensure your oil is vegan-certified. The texture remains fudgy, though vegan donuts may be slightly denser. Test with 1 ripe banana first to adjust sweetness.
Can I make the batter ahead of time?
Yes! Store the batter in an airtight container in the fridge for up to 3 days or freeze for 3 months. Thaw overnight in the fridge before using. For frying, you may need to adjust the oil temperature slightly (340°F works well for chilled batter). The flavor develops deeper after resting, making them even more delicious the next day!
What's the best way to store leftover glazed donuts?
Place donuts in an airtight container with parchment paper between layers to prevent sticking. They'll stay fresh for 3 days at room temperature. For longer storage, freeze unglazed donuts for 2 months—glaze them fresh when ready. Reheat for 10 seconds in the microwave with a damp paper towel for crispiness. Avoid refrigerating glazed donuts—they lose their texture!
