Ingredients for banana cake recipe 1 banana
Twelve ingredients transform one banana into a moist, restaurant-quality cake without dry crumbs.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Banana 🍌 | 1 whole | Spotty yellow with slight softness |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for even distribution |
| Granulated Sugar 🍚 | ½ cup | Light brown preferred for depth |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even melting |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Pure Vanilla Extract 🌸 | 1 tsp | High-quality, no alcohol aftertaste |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for aromatic punch |
| Baking Powder 🍞 | 1 ½ tsp | Double-acting for lift |
| Salt 🧂 | ¼ tsp | Fine sea salt for balance |
| Whole Milk 🥛 | ¼ cup | Full-fat for moisture retention |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for brightness |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor preferred |
| Powdered Sugar 🍚 | ¼ cup | For optional glaze |
The banana's ripeness is non-negotiable—look for spots and slight softness at the stem. Trader Joe's and Whole Foods often have perfect ones, but any grocery store's produce section works if you check the bunch carefully. The flour should be sifted before measuring to prevent dense layers, and King Arthur brand is my go-to for consistent results. Butter matters here: European-style has higher fat content, which translates to richer flavor and better moisture retention. Store it in the fridge until ready to use—cold cubes melt evenly in the batter.
No vanilla extract? Seeds from a vanilla bean work beautifully, or a dash of almond extract in a pinch. The cinnamon should be freshly ground—pre-ground loses potency quickly, and Penzeys or McCormick are reliable brands. Substituting milk? Full-fat coconut milk adds richness, but the texture will differ slightly. For the lemon juice, fresh is non-negotiable—bottled lacks brightness. If you're avoiding powdered sugar in the glaze, a drizzle of honey or maple syrup works wonderfully instead.
This batter keeps in the fridge for up to 2 days, though I recommend baking it fresh for peak moisture. The cake reheats beautifully—wrap a slice in foil and microwave for 20 seconds to restore tenderness. For longer storage, slice and freeze portions between parchment paper for up to 3 months. The glaze sets quickly, so prepare it last—it's the perfect finishing touch that elevates this simple cake to something special.
Why You'll Love This Recipe
- No Mash Required: I swear by this trick—just slice that one ripe banana right into the batter. No sticky fingers, no over-mixing, and the chunks stay juicy while the flour soaks up just enough to keep things tender. (Yes, even if you’re the kind of person who burns toast.)
- Butter-Sugar Magic: That melted butter and sugar combo? It’s basically cake nirvana—rich, caramelized edges that taste like a bakery’s secret. The egg ties it all together with a moist crumb that’s neither dry nor gummy. Honestly, I’ve made this with brown sugar too, but the granulated gives it that classic, slightly crisp top.
- One-Bowl, Many Uses: This cake is my go-to for breakfast, dessert, or even a quick snack when I’m craving something sweet but don’t want to fuss. Slice it thin for pancake-style stacks with peanut butter, or serve it warm with a scoop of ice cream. (Between us, I’ve even packed it for lunch—no judgment.)
- Pantry Staples Only: You’re using things you already have—no weird ingredients, no last-minute grocery runs. That one banana? It’s probably sitting on your counter, getting spotted. The rest? Flour, sugar, butter, eggs. Boom. Done. And since it keeps well for days (if it lasts that long), it’s my budget-friendly guilt-free treat.
Step-by-step instructions for banana cake with 1 banana
Transform a single ripe banana into a perfectly moist cake with these precise techniques.
Prep the Banana and Mix Dry Ingredients
Mash the 1 whole ripe banana in a medium bowl until completely smooth—no lumps should remain. This ensures even distribution throughout the batter. The banana should be spotty yellow with slight softness, as underripe fruit will yield a denser cake.
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 1.5 teaspoons baking powder, 1.5 teaspoons ground cinnamon, and ¼ teaspoon salt. Sift the flour first for even distribution—this prevents dense pockets in the final cake. Set aside until ready to combine with wet ingredients.
Cream Butter and Sugar, Then Combine Wet Ingredients
In a stand mixer fitted with the paddle attachment, beat the ½ cup unsalted butter (cold, cubed) and ½ cup granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and become pale in color. This step incorporates air, which creates that tender crumb structure we're after.
Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition. Stir in the 1 teaspoon pure vanilla extract, 1 tablespoon lemon juice, ¼ cup whole milk, and ¼ cup vegetable oil. The lemon juice brightens the banana flavor while the milk and oil add moisture—critical for that single-banana cake texture.
Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients while mixing on low speed for 30-45 seconds until just combined. Avoid overmixing—you should still see a few flour streaks. The mashed banana will create a thick, slightly sticky batter. If it appears too thick, add 1 tablespoon milk to reach a smooth consistency.
Fold in the banana mixture by hand using a silicone spatula, ensuring even distribution. The batter should be thick but pourable. Here's the thing—this recipe relies on the banana's natural moisture, so don't be tempted to add extra liquid. The cake will rise properly while remaining tender.
Bake to Golden Perfection
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean with just a few moist crumbs.
The cake should be golden brown on top with slightly domed edges. If the edges brown too quickly, loosely tent the pan with aluminum foil after 20 minutes to prevent overbrowning. The internal temperature should reach 205-210°F—this ensures complete doneness without drying out.
Cool and Glaze (Optional)
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and allows the moisture to redistribute evenly throughout the cake.
For the optional glaze, whisk together the ¼ cup powdered sugar with 1-2 tablespoons milk until smooth. Drizzle over the cooled cake and let it set for 5 minutes before serving. The glaze adds a delicate sweetness that complements the natural banana flavor without overpowering it.
Pro Tips For Making Banana Cake Recipe 1 Banana
- Mash Bananas Thoroughly: Skip the blender—use a fork and really work those bananas until smooth. Lumps in the batter make for a dense cake, and trust me, you’ll taste the difference. If the mix looks too thick, add a splash of milk (not water) to loosen it up.
- Preheat Pan 10 Minutes: I used to rush this, and my cakes always came out gummy in the center. Set your oven to 350°F and let the pan sit in there for 10 minutes before pouring. The butter’s heat will melt faster, and the edges won’t stay pale.
- Don’t Overmix the Batter: Once you fold in the flour, stop after 10-12 strokes. Overmixing makes the cake tough—like eating a dense, sad sponge instead of a tender crumb. If the batter looks streaky, that’s fine; it’ll even out in the oven.
- Use Room-Temp Butter: Cold butter from the fridge won’t cream properly, and your cake will turn out greasy or uneven. Let it sit out for 30 minutes before measuring—soft enough to press a thumbprint into it, but not melted. (Yes, even if you’re impatient like me.)
Flavor customization for this recipe
Sweet-Spiced Variations
Add ½ teaspoon nutmeg and ¼ teaspoon cardamom to the dry ingredients for a warm, aromatic twist. These spices deepen the banana flavor while adding complexity. I find Badia Spice ground nutmeg works best—it’s less bitter than store brands. For a tropical touch, swap cinnamon for 1 teaspoon orange zest and add ¼ teaspoon ginger to the wet ingredients. 🌶️
Chocolate Banana Fusion
Fold in 2 tablespoons cocoa powder with the dry ingredients and reduce the sugar to ⅓ cup. The cocoa enhances the banana’s natural sweetness while adding richness. Top with a dusting of powdered sugar> or a drizzle of melted dark chocolate for a decadent finish. This version tastes like dessert but still counts as a breakfast cake.
Citrus Zest Boost
Boost the lemon juice to 2 tablespoons and add 1 tablespoon lime juice for a tangy kick. Pair this with 1 teaspoon lime zest> mixed into the wet ingredients. The acidity brightens the banana flavor and prevents the cake from tasting overly sweet. Fresh lime juice is key—bottled lacks the same vibrancy.
Nutty Crunch Add-Ins
Fold in ½ cup chopped walnuts or pecans after combining the wet and dry ingredients. Toast the nuts first in a dry pan for 3-4 minutes> until fragrant to enhance their flavor. For a finer texture, pulse them in a food processor. This adds a satisfying crunch that contrasts beautifully with the cake’s soft crumb.
Cream Cheese Swirl
Mix 4 ounces softened cream cheese with 1 tablespoon powdered sugar> and spread dollops over the batter before baking. Swirl gently with a knife to create marbled streaks. The cream cheese adds a tangy richness that cuts through the banana’s sweetness. This version feels extra indulgent but stays moist thanks to the banana’s natural moisture.
Coffee-Infused Depth
Replace 1 tablespoon milk> with an equal amount of strong brewed coffee or espresso. The caffeine enhances the banana flavor and adds subtle bitterness that balances the sweetness. For a stronger effect, add ½ teaspoon instant coffee> to the dry ingredients. This variation is perfect for breakfast or an after-dinner treat with a cup of coffee. ☕

Frequently asked questions
Why does this recipe use only 1 banana?
This recipe proves that one perfectly ripe banana delivers all the natural sweetness and moisture needed for a tender cake. The banana's sugars caramelize during baking, creating that classic banana cake flavor without requiring multiple bananas. Plus, it's a great way to use up that one overripe banana in your fruit bowl before it gets too soft!
Can I make this cake without eggs?
Yes! Replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 5 minutes to gel). For a lighter texture, use ½ cup unsweetened applesauce instead. Both alternatives work well while keeping the cake moist—just be aware the texture will be slightly denser than with eggs.
How do I know when the cake is fully baked?
Insert a toothpick into the center—it should come out with just a few moist crumbs (not wet batter). The cake should also spring back slightly when gently pressed in the middle. For extra accuracy, check the internal temperature with an instant-read thermometer: 205-210°F means perfect doneness.
What's the best way to store banana cake?
Wrap the cake tightly in plastic wrap and store at room temperature for up to 3 days. For longer storage, slice and freeze portions between parchment paper for up to 3 months. To reheat, microwave a slice for 15-20 seconds or warm in a 300°F oven for 10 minutes to restore moisture.
Can I use this recipe for a layer cake?
Yes! Divide the batter evenly between two 6-inch round pans or three 5-inch pans. Bake at 350°F for 25-30 minutes (check with a toothpick). For assembly, spread ½ cup cream cheese frosting between layers and cover the top. The single-banana approach works perfectly for layer cakes too!
