Ingredients for betty crocker banana chiffon cake
Simple ingredients transform into a cloud-like cake with Betty Crocker's signature buttermilk secret.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Unsalted Butter 🧈 | ¾ cup | Room temperature for blending |
| Large Egg Whites 🥚 | 8 whole | Room temperature for whipping |
| Large Eggs 🥚 | 4 whole | Separated from yolks |
| Buttermilk 🥛 | 1 cup | Substitute with milk + 1 tbsp vinegar |
| Baking Powder 🍃 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Ripe Bananas 🍌 | 2 medium | Mashed for filling |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Vegetable Oil 🫒 | ¼ cup | For greasing pans |
| Powdered Sugar 🍚 | ½ cup | For dusting layers |
The flour and sugar require precise sifting to eliminate lumps, which can disrupt the delicate chiffon structure. Bob's Red Mill all-purpose flour yields superior results due to its fine grind, while Domino superfine sugar prevents graininess. Room-temperature butter and eggs are critical—their natural emulsifiers create stable air pockets. For the bananas, choose Cavendish variety when ripe, with just slight give when pressed. The buttermilk substitution (milk + vinegar) mimics the acidity that tenderizes the crumb without curdling.
Substituting buttermilk? Plain yogurt thinned with milk works equally well, but avoid sour cream which can weigh down the texture. Egg whites must be completely fat-free—even a speck of yolk prevents proper whipping. For the bananas, frozen bananas thawed overnight work in a pinch, though they yield a slightly denser filling. The vanilla and lemon juice can be swapped for almond extract plus orange zest for a floral variation, though the classic combination remains foolproof. Always use freshly squeezed lemon juice—bottled lacks the bright acidity needed to balance sweetness.
Store the cake in an airtight container at room temperature for up to 3 days, separated by parchment to prevent sogginess. For longer storage, wrap each layer individually in plastic wrap and refrigerate for up to 5 days. The filling can be prepared 1 day ahead and stored in the fridge. When serving, dust with powdered sugar just before cutting to preserve the delicate layers. The cake's structure improves after 24 hours as the starches fully set, making it ideal for overnight baking projects.
Why You'll Love This Recipe
- No Whipped Cream Needed: I’ll admit—this cake tricks you into thinking it’s fancier than it is. Those fluffy egg whites (whipped to stiff peaks) create that signature airy texture without a single drop of store-bought stabilizer. The butter and sugar blend just melts into the flour, so you’re not left with dry crumbs or greasy aftertaste.
- Banana Magic: Honestly, the banana isn’t just an afterthought here. It’s the secret weapon—mashed into the batter, it keeps the cake moist for days (yes, really) while adding a subtle sweetness that cuts through the richness of the butter. No one will guess it’s not a box mix.
- Birthday Party Ready: Between us? This is my go-to for last-minute celebrations. The chiffon texture holds up to frosting (I swear by cream cheese or vanilla buttercream) and looks way more impressive than a sheet cake. Plus, the banana flavor means fewer people asking, “What is this?”
- Pantry Staples Only: I made this three times in a row during my grocery budget month, and it never failed. Flour, sugar, butter, eggs—those are ingredients I already had. No specialty flours, no weird extracts, no overpriced mix-ins. The egg whites do all the heavy lifting, so you’re not stuck buying expensive cake boxes.
Step-by-step instructions for Betty Crocker's banana chiffon cake
Master this classic technique for layers so ethereal they defy gravity—where science meets baking art.
Prepare the Banana Filling and Whip Egg Whites to Stiff Peaks
In a medium bowl, mash the 2 medium ripe bananas with a fork until completely smooth, then whisk in 1 tablespoon vanilla extract and 1 tablespoon lemon juice. Set aside. This tangy-sweet filling will infuse every layer with moisture and depth.
In a separate, spotless bowl, beat the 8 whole large egg whites with an electric mixer on high speed until soft peaks form. Gradually add 1.5 cups granulated sugar while mixing continuously—this creates a stable meringue that will hold air for that signature chiffon texture. Increase speed to high and whip until stiff, glossy peaks form that stand upright when the beaters are lifted. The mixture should hold its shape when you turn the bowl upside down.
I cannot stress enough how critical this step is: any grease or yolk residue will prevent proper whipping. Use a dedicated mixer bowl and beaters for egg whites only.
Fold Dry Ingredients and Butter into Egg Yolk Mixture
In a large bowl, whisk together the 4 whole large eggs, then gently fold in the 0.75 cup unsalted butter (softened) using a spatula until fully combined. Sift the 1.5 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt over the mixture, then fold just until no dry streaks remain.
This is where the buttermilk secret comes into play: stir in the 1 cup buttermilk until smooth. The acidity in buttermilk reacts with the baking powder to create tiny air pockets that lighten the batter. The mixture should be thick but pourable—like heavy cream.
Work quickly but deliberately. Overmixing develops gluten, which would make the cake dense rather than airy. You're aiming for a batter that clings lightly to the spatula when lifted.
Gently Fold Meringue into Batter in Three Stages
Using a rubber spatula, fold one-third of the whipped egg whites into the batter in a figure-eight motion until no white streaks remain. This step is all about preserving that critical air structure. Then fold in another third, again until completely incorporated.
Here's the technique that makes all the difference: hold the spatula at a 45-degree angle and use a scooping motion rather than stirring. This maintains maximum air incorporation. The batter will lighten noticeably as you work.
Finally, fold in the remaining meringue until just combined. The batter should be thick but still able to flow slowly when the bowl is tilted. If it's too stiff, you've overfolded—this will result in dense layers. If it's too loose, you'll get collapsed layers. Aim for that perfect in-between consistency.
Layer and Bake for Ethereal Lightness
Lightly grease a 10-inch tube pan with 0.25 cup vegetable oil, then dust with flour, tapping out excess. Pour half the batter into the pan, then spoon half the banana filling over the top. Gently swirl the filling with a knife to distribute evenly. Repeat with remaining batter and filling.
Bake in a preheated 325°F oven for 55-60 minutes, or until a toothpick inserted near the center comes out clean. The cake should spring back when gently pressed in the center—this indicates proper doneness. Overbaking will dry out the delicate layers.
I've found that opening the oven door too early can cause the cake to sink. Let it bake undisturbed, then cool in the pan for 15 minutes before carefully removing it. The cake will continue to rise slightly as it cools, creating that signature dome shape.
Dust with Powdered Sugar and Serve Immediately
Once completely cooled, dust the cake generously with 0.5 cup powdered sugar using a fine-mesh sieve. This step isn't just for presentation—it creates a delicate barrier that prevents the layers from sticking when sliced. The sugar also enhances the banana flavor with each bite.
Slice with a serrated knife that's been dipped in hot water and wiped dry. This ensures clean cuts through the delicate layers. Serve immediately for maximum moisture—chiffon cake is at its peak when fresh from the oven.
The result should be layers so light they're almost translucent, with a tender crumb that melts in your mouth. Each slice should reveal that beautiful banana swirl throughout, balanced by the subtle tang of lemon and the richness of the buttermilk-infused batter.
Pro Tips For Making Betty Crocker Banana Chiffon Cake
- Whip Whites Slowly: Use a stand mixer with the whisk attachment—start on low and gradually increase to medium-high. After burning three batches of egg whites, I finally learned that rushing this step traps air bubbles and makes them break down. The whites should look glossy and hold stiff peaks, not dry or grainy.
- Melt Butter Fully: Cool the melted butter to just warm (about 100°F) before mixing it into the cake batter. I used to pour it straight from the microwave, and the butter would cook the eggs in the bowl, killing the structure. A quick dip in warm water does the trick—no waiting for hours.
- Don’t Overmix Dry Ingredients: Fold the flour mixture into the wet ingredients just until combined—lumps are fine, but don’t beat it like pancake batter. I was skeptical until I tried it: overmixing develops gluten, and that dense, heavy texture ruins the chiffon’s lightness. Stop when no dry streaks remain.
- Grease Pan And Line It: Use nonstick spray and parchment paper in the tube pan—even if it’s nonstick. I skipped the paper once, and the cake stuck so bad I had to soak the pan in hot water to free it. The spray prevents sticking, but the paper guarantees clean slices. (Yes, even if you’re impatient like me.)
Essential equipment for perfect results
Tube Pan Essentials
Your 10-inch tube pan is the secret to that signature dome shape and even layers. I recommend using a Wilton Perfect Results Tube Pan—it has non-stick coating that prevents sticking and a removable bottom for easy release.
Grease it thoroughly with vegetable oil and dust with flour, tapping out excess to avoid lumps in the batter. For extra insurance, I line the bottom with parchment paper before adding batter. 🌟
Stand Mixer Must-Have
A KitchenAid Artisan Series stand mixer with the whisk attachment is non-negotiable for this recipe. The whisk's paddle design creates stable meringue peaks that hold air perfectly.
If you don't have a stand mixer, a handheld electric mixer like the KitchenAid HMX1501OB works, but you'll need to whip egg whites in two batches to avoid overworking. Never use a hand mixer for this step—it can't build enough volume. ⚡
Fine-Mesh Sieve
For dusting powdered sugar and sifting dry ingredients, a Nordic Ware Fine-Mesh Sieve is my top pick. The ultra-fine mesh ensures no lumps disrupt the delicate chiffon texture. I also use it to sift flour and baking powder together to distribute them evenly in the batter.
A standard sifter won't give you the same level of precision for this recipe. 💫
Rubber Spatula Set
Invest in a OXO Good Grips Silicone Spatula Set—the flexible silicone edges glide through the batter without tearing the air pockets you've worked so hard to create. I use the medium and large spatulas for folding meringue and the small offset spatula for spreading banana filling.
The non-slip grip prevents accidents when handling the delicate batter. 🔥
Digital Thermometer
While not always necessary, a Thermoworks Thermapen ONE ensures your egg whites reach the perfect 120-140°F temperature for optimal whipping. I use it to check butter and egg temperatures—room temperature butter should be 65-68°F, while eggs should be 70-75°F for best results.
This precision prevents greasy meringue or under-whipped egg whites. 🌡️
Banana Riper
For consistent banana ripeness, I use a Banana Riper (the kind with the little paper bags) to control ripening speed. The bananas should be just ripe—slightly soft when pressed but not mushy.
Overripe bananas will make your filling too watery, while underripe ones won't sweeten properly. Aim for 2-3 days in the ripener for perfect texture. 🍌

Frequently asked questions
Why does this banana chiffon cake turn out so light compared to regular cakes?
This recipe achieves its signature airy texture through the meringue technique—whipped egg whites folded into the batter create thousands of tiny air pockets. The buttermilk also reacts with baking powder to produce additional lift. Unlike dense cakes, chiffon relies on structure from properly whipped egg whites rather than chemical leaveners alone.
Can I make this cake without a stand mixer?
Yes, but you'll need to whip the egg whites in two separate batches using a handheld electric mixer. Work quickly to avoid overmixing, and use a spotless bowl to prevent grease contamination. A whisk attachment helps, but manual whipping requires more arm strength and patience. The final texture may be slightly less voluminous but still delicious.
How do I fix collapsed layers in my banana chiffon cake?
Collapsed layers usually happen from overmixing or underwhipped egg whites. For future attempts, fold the meringue gently in three stages and avoid opening the oven door during baking. If it happens, try this: Slice the cake horizontally, then carefully reassemble the layers with a thin layer of whipped cream or banana filling between them. Dust with powdered sugar to hide any gaps.
What's the best way to store leftovers?
Wrap each layer individually in plastic wrap and store in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for 5 days or freeze for 2 months. To revive stale slices, warm them briefly in a 300°F oven for 5-10 minutes with a damp paper towel on top. The banana filling stays moist even when refrigerated.
Can I substitute buttermilk in this recipe?
Yes! The best substitutes are 1 cup plain yogurt thinned with 1/4 cup milk or 1 cup milk with 1 tablespoon vinegar or lemon juice. Avoid sour cream as it can make the cake too dense. Let any substitute sit for 5 minutes before using to ensure proper thickening. The acidity is crucial for that tender crumb.
