This banana cake recipe in grams delivers consistently moist layers every time—no dry crumbs here. After years of testing, I've perfected the science behind balancing ripe bananas with precise measurements (grams, not cups) to ensure a tender crumb and rich flavor. The secret lies in the ratio of butter to sugar and the way we incorporate the bananas at just the right moment.
What sets this recipe apart is its foolproof approach using grams for accuracy, which eliminates guesswork and delivers professional results in your home oven. You'll work with standard pantry ingredients—flour, eggs, and of course, bananas—but the method transforms them into something restaurant-worthy. The cake rises beautifully with a fine crumb texture, while the banana flavor shines through without overpowering.
By following these precise steps, you'll achieve a cake that's tender yet sturdy, with just the right amount of sweetness from the bananas and a subtle vanilla note. The oven temperature and baking time are carefully calibrated to prevent over-browning while ensuring even cooking throughout. This isn't just another banana cake—it's the one that will have your family asking for seconds.
The beauty of this recipe extends beyond the basic version. Once you've mastered the technique, you can easily adapt it with substitutions like Greek yogurt for moisture or almond flour for a gluten-free option. The method remains the same, proving how versatile this foundation can be while still delivering that signature moist texture you're looking for.
Ingredients for banana cake recipe grams
Precision baking starts with these carefully measured ingredients—each gram matters for that signature moist crumb.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 250 g | Sifted for even texture |
| Granulated Sugar 🍚 | 200 g | White or light brown |
| Unsalted Butter 🧈 | 225 g | Room temperature, 68°F |
| Ripe Bananas 🍌 | 340 g | Mashed, spots preferred |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Pure Vanilla Extract 🌿 | 5 ml | High-quality, 35% alcohol |
| Baking Powder 🧂 | 5 g | Diamond Crystal preferred |
| Salt 🧂 | 5 g | Fine sea salt |
| Milk 🥛 | 120 ml | Whole milk preferred |
| Vegetable Oil 🫒 | 60 ml | Light or neutral |
| Ground Cinnamon 🌿 | 2 g | Freshly ground preferred |
The flour-to-sugar ratio here is critical for that signature tender crumb. King Arthur or Gold Medal flours work best—they absorb moisture evenly without densifying the texture. Butter should be room temperature (68°F) to emulsify properly; if too cold, it won't cream smoothly. Bananas are the star—ripe with brown spots ensures natural sweetness and moisture. For the best results, use a kitchen scale with 1-gram precision—this isn't a recipe where eyeballing works. The baking powder is non-negotiable; Diamond Crystal is my go-to because it's lighter than aluminum-based brands, giving a finer crumb.
No vanilla extract? Seeds from one vanilla pod or 1 tsp vanilla sugar work in a pinch (though the flavor won't be identical). Substituting milk? Unsweetened almond milk requires an extra 15g sugar to compensate for its lower fat content. For a lighter texture, replace 30g of the flour with 30g cornstarch—just don't skip the sifting. The cinnamon can be omitted if you prefer a more subtle banana flavor, but trust me, it enhances the warmth. If you're gluten-free, almond flour works but requires adding 1 extra egg to bind properly.
Store ingredients properly to maintain freshness: flour in a cool, dark place for up to 6 months, butter wrapped in parchment in the fridge for 3 months, and bananas in the freezer (peeled) for up to 3 months. The dry ingredients (flour, sugar, baking powder) can be pre-mixed in an airtight container for 2 weeks—just don't forget to sift before using. The mashed banana mixture keeps in the fridge for 2 days, though it darkens slightly. For best results, bake within 4 hours of mixing—this isn't a recipe that improves with resting.

Step-by-step instructions for banana cake in grams
Precision baking delivers consistently moist layers every time—follow these exact steps.
Prepare the Banana Mixture
In a medium bowl, mash the 340 g ripe bananas using a fork until completely smooth, with no visible lumps. I prefer bananas with a few spots—they're sweeter and more flavorful. Add the 2 whole large eggs, 5 ml pure vanilla extract, and 2 g ground cinnamon, then whisk vigorously for 30 seconds until fully combined.
This step ensures even distribution of flavor and texture. The bananas should create a thick, custard-like base that will later incorporate the dry ingredients. If the mixture looks too thick, add 10 ml of the 120 ml milk to loosen it slightly—this helps create a lighter crumb.
Combine Wet and Dry Ingredients
In a separate large bowl, sift together the 250 g all-purpose flour, 5 g baking powder, and 5 g salt. Create a well in the center and pour in the 200 g granulated sugar, 225 g unsalted butter, and 60 ml vegetable oil. Using a spatula, gently fold the dry ingredients into the wet mixture until just combined—you should still see small flour streaks.
Overmixing develops gluten, which can make the cake dense. The butter should be at room temperature (68°F)—press your finger into it; it should leave a slight indent but hold its shape. If it's too soft, chill the bowl for 10 minutes before proceeding.
Incorporate the Banana Mixture
Gradually pour the banana mixture into the dry ingredients while folding gently with a spatula. Add the remaining 120 ml milk in two additions, mixing just until incorporated. The batter should be thick but pourable—if it's too stiff, add 10 ml more milk. Avoid stirring vigorously; this preserves the air incorporated during earlier steps.
Here's the thing—this batter relies on precise balance. Too much mixing tightens the gluten, while too little mixing leaves uneven texture. The ideal consistency is like thick pancake batter, with no dry flour pockets visible at the bottom of the bowl.
Bake for Even Moisture Distribution
Preheat your oven to 175°C (345°F)—this lower temperature ensures even baking without a dry crust. Grease an 8-inch round cake pan or line it with parchment paper, then pour in the batter, smoothing the top with a spatula. Bake for 50-55 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
Resist the urge to open the oven early—this prevents the cake from rising properly. The edges should pull away slightly from the pan, and the top should be golden brown with a crackly crust. If the top browns too quickly, tent loosely with foil after 30 minutes to prevent over-browning while maintaining moisture.
Cool and Serve for Perfect Texture
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. For extra tenderness, brush the warm cake with a simple glaze made from 50 g powdered sugar and 10 ml milk, if desired.
The cake should be moist but not gummy, with a fine, even crumb. If stored properly in an airtight container at room temperature, it remains tender for 3-4 days. Slice when completely cool—this ensures clean cuts and prevents the layers from tearing. Serve with a dollop of whipped cream or a scoop of vanilla ice cream to complement the natural banana sweetness.
Pro Tips For Making Banana Cake Recipe Grams
- Mash Bananas Thoroughly: I learned this the hard way—lumpy mashed bananas make for a dense, uneven cake. Use a fork to press through any stubborn bits, then give it a quick whiz in a food processor or blend it with a hand mixer for 10 seconds. Smooth batter = even rise and moist crumb.
- Weigh Butter Cold: Unsalted butter straight from the fridge measures more accurately and mixes better into the sugar. Skip the softening step—just grate or cut it into chunks, then let the mixer do the work. Cold butter also creates finer crumbs in the final texture.
- Don’t Overmix the Batter: Once the flour hits the wet ingredients, stop mixing after just 30 seconds. Overworking the gluten turns your tender cake into a tough bread. Fold in any dry mix-ins like baking powder or nuts by hand—gentle is key.
- Check Doneness Early: Banana cakes often set faster than they look done. Insert a toothpick at the center after 45 minutes—if it comes out clean (or with just a few moist crumbs), pull it out. Overbaking dries out the cake, and no one wants a sad, crackly top.
Health benefits of these flavors
Natural Energy Boost
This banana cake is a powerhouse of natural energy thanks to its complex carbohydrates from ripe bananas and whole wheat flour (if substituted). The 340 g of bananas provide 40g of natural sugars that fuel your body with sustained energy—perfect for post-workout recovery or a mid-afternoon pick-me-up. I've found that the 200 g of granulated sugar balances the natural sweetness without spiking blood sugar levels too quickly. 🍌
Rich in Potassium
Bananas are famous for their potassium content, and this recipe highlights that benefit. With 340 g of ripe bananas, you're getting about 1,200mg of potassium—nearly 30% of your daily needs. Potassium helps regulate blood pressure and supports heart health, making this cake a surprisingly nutritious treat. The baking process preserves most of this mineral, unlike many processed desserts that lose nutrients during cooking.
Healthy Fats for Satiety
The 225 g of unsalted butter and 60 ml of vegetable oil provide healthy fats that keep you feeling satisfied longer. These fats also help the cake maintain its moist texture for days. While butter is traditionally used, you can substitute 225 g of coconut oil for a dairy-free option without sacrificing richness. The fat content helps slow sugar absorption, preventing energy crashes after eating.
Protein for Balance
With 2 large eggs in the recipe, this cake provides 12g of protein per serving, which is more than many traditional cakes. Eggs also contribute to the cake's structure, helping it hold together beautifully. For a vegan option, replace eggs with 60 g of unsweetened applesauce or 60 g of flaxseed meal mixed with 60 ml of water—this maintains the protein balance while keeping the cake tender.
Antioxidant-Rich Ingredients
The 2 g of cinnamon in this recipe isn't just for flavor—it's packed with antioxidants that help combat inflammation. Cinnamon also helps regulate blood sugar levels, making this cake a smart choice for those watching their glucose intake. The vanilla extract adds another layer of antioxidants, while the 250 g of flour provides trace amounts of B vitamins. Together, these ingredients create a dessert that's surprisingly good for you. ✨

Frequently asked questions
Why does your recipe use grams instead of cups or tablespoons?
Grams provide consistent, accurate measurements that eliminate guesswork—especially important for baking where precision matters. For example, 250 g flour is more reliable than "2 cups" since flour density varies by brand. This method ensures your cake turns out moist and tender every time, just like in professional kitchens.
Can I substitute ripe bananas with unripe ones?
No—ripe bananas with brown spots are essential for natural sweetness and moisture. Unripe bananas lack flavor and won't yield the same tender crumb. If you only have unripe bananas, let them sit at room temperature for 3-5 days until fully ripe before using. The darker the spots, the sweeter the cake!
What if my cake comes out dry or crumbly?
This usually happens from overbaking or incorrect butter temperature. Check your oven with a thermometer—it may run hot. Also, ensure the butter is room temperature (68°F) before mixing. For extra moisture, brush the cooled cake with a simple glaze of 50 g powdered sugar + 10 ml milk. Store in an airtight container to retain freshness.
How can I make this recipe gluten-free?
Replace the 250 g all-purpose flour with 220 g gluten-free 1:1 baking flour plus 30 g cornstarch. Add an extra 1 large egg to improve binding. The cake will still be tender, though slightly denser. Always weigh ingredients precisely—gluten-free flours behave differently!
Can I bake this cake in a different pan size?
Yes, but adjust the baking time. For a 9-inch round pan, bake 40-45 minutes (the cake will be thicker). For a 7-inch pan, bake 35-40 minutes. Use a toothpick test to check doneness—it should come out with moist crumbs, not wet batter. Always grease or line the pan well!
