Ingredients for america's test kitchen banana cake
Ripe bananas, melted butter, and warm spices create this foolproof banana cake with perfect moisture every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Spot blackened peel for sweetness |
| Unsalted Butter 🧈 | 1 cup | Melted, cooled slightly |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Large Eggs 🥚 | 2 whole | Room temperature |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned lightly |
| Baking Soda 🧂 | ½ tsp | Pure baking soda |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Ground Allspice 🌶️ | ¼ tsp | Freshly ground |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Milk 🥛 | ½ cup | Whole or 2% preferred |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla extract |
The bananas are non-negotiable here—look for ones with black specks on the peel, those are the sweetest. Whole Foods or your local grocery store’s produce section usually has the ripest ones. Butter matters too: unsalted is a must, and make sure it’s melted but not hot. The spice blend (cinnamon, nutmeg, allspice) is what makes this cake stand out—Penzeys or local spice shops carry the best quality. For flour, King Arthur or Bob’s Red Mill brands are ideal—they’re sifted and consistent.
No ripe bananas? Use 1/2 cup banana puree (blend with a splash of milk) instead. Out of vanilla? Almond extract at half the amount works in a pinch. The milk can be swapped for buttermilk or evaporated milk for extra richness. For a gluten-free version, substitute 1:1 gluten-free flour blend but add an extra 0.5 tsp baking soda. The sugar can be swapped for light brown sugar for a deeper caramel flavor—just reduce the milk by 2 tbsp to balance moisture.
Bananas keep for 3-4 days at room temperature once ripe, so use them up quickly. Store flour and spices in airtight containers away from heat to preserve freshness. The melted butter can be prepped ahead and stored in the fridge for up to 2 days. This cake reheats beautifully—wrap a slice in foil and microwave for 15-20 seconds to restore moisture. Leftovers keep for 3 days in the fridge or can be frozen for 2 months for a quick dessert.

Step-by-step instructions for america's Test Kitchen banana cake
Here's the method that guarantees a perfectly moist cake with warm spice harmony every time.
Prep Ingredients for Optimal Texture
First, preheat your oven to 350°F and grease a 9-inch round cake pan with butter, then dust with flour. This ensures easy release later. While the oven heats, peel the 3 medium ripe bananas and mash them thoroughly in a mixing bowl until completely smooth—no lumps. The riper the bananas, the sweeter and more flavorful your cake will be.
In a separate small bowl, whisk together the 2 whole large eggs, 0.5 cup milk, and 1 tsp vanilla extract. This creates a smooth liquid base that will blend seamlessly with the banana mixture. Let these ingredients sit at room temperature for 10 minutes before using—cold ingredients can make cakes dense.
Cream Butter and Sugar for Lightness
In a large mixing bowl, combine the 1 cup unsalted butter (cooled slightly) and 1.5 cups granulated sugar. Using an electric mixer on medium-high speed, beat for 3-4 minutes until the mixture is light and fluffy. You'll see the sugar dissolve completely and the mixture double in volume. This step is crucial for creating a tender, moist crumb—don't rush it.
Add the mashed bananas to the butter-sugar mixture and mix on medium speed for 1 minute until fully incorporated. Then add the egg-milk mixture and mix for another 30 seconds. The batter should be smooth with no visible streaks of butter or egg. At this stage, the batter will look slightly thick but should still be pourable.
Combine Dry Ingredients for Perfect Rise
In a medium bowl, sift together the 2 cups all-purpose flour, 0.5 tsp baking soda, 0.5 tsp salt, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.25 tsp ground allspice. Sifting prevents lumps and ensures even distribution of the spices. The warm spices create that signature banana cake aroma while the baking soda helps with lift.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—about 30 seconds. Overmixing develops gluten, which can make the cake tough. The batter should be thick but still smooth. At this point, you can do a quick taste test: the batter should be sweet and spiced, with a hint of banana flavor.
Bake to Golden Perfection
Pour the batter into the prepared cake pan and smooth the top with a spatula. Tap the pan gently on the counter a few times to release any air bubbles that may have formed. Bake in the preheated oven for 50-55 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and slightly pulled away from the sides of the pan.
I've found that baking times can vary slightly depending on your oven, so start checking at the 45-minute mark. The cake is done when it springs back slowly when touched in the center. Let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling helps the cake set properly and prevents cracking.
Serve with Warm Spice Harmony
Once completely cooled, slice the cake into 4 equal servings. The interior should be moist with a fine crumb, and each slice should reveal the beautiful warm spice flecks throughout. The cake will keep well at room temperature for 2-3 days, wrapped tightly in plastic wrap, or can be refrigerated for up to 5 days—though I find it's best enjoyed fresh.
For serving, I like to dust the top with a light layer of powdered sugar or serve it with a dollop of whipped cream. The warm spices—cinnamon, nutmeg, and allspice—create a comforting aroma that pairs perfectly with the natural sweetness of the bananas. Each bite should deliver that perfect balance of moisture, sweetness, and spice that makes this cake so special.
Pro Tips For Making America'S Test Kitchen Banana Cake
- Mash Bananas Thoroughly: The recipe calls for 3 ripe bananas, but I learned this the hard way—lumpy mashed bananas make for a dense, uneven cake. Use a fork first, then give it a quick pulse in a food processor or press through a fine-mesh sieve to break up all the fibers. Your cake will be lighter and more tender, even if you don’t see the difference in the batter.
- Cream Butter and Sugar Slowly: The recipe’s butter-sugar mix is the foundation, so don’t rush it. Start on medium speed and gradually increase to high only after 1-2 minutes—this incorporates air without turning the butter greasy. I used to crank it up immediately, and the cake always ended up slightly flat. Patience here makes a real difference in texture.
- Don’t Overmix the Batter: The second you add the flour, stop mixing as soon as it’s just combined. Overmixing develops gluten, and that’s how you end up with a tough, chewy banana cake instead of the soft, moist one this recipe promises. Fold gently with a spatula—yes, even if there are a few flour streaks. Your future self will thank you.
- Use Room-Temperature Eggs: Cold eggs from the fridge can curdle when mixed into the warm butter mixture, leaving streaks in the batter. Take the eggs out 15-20 minutes before you start—no need to wait longer, or they’ll get too runny. The recipe’s creaming step relies on smooth incorporation, and cold eggs mess that up every time.
Creative variations of this recipe
Spiced Rum Infusion
Elevate your banana cake by swapping ½ cup of the milk with spiced rum (like Captain Morgan Original or Kahlúa). The rum adds depth and warmth that pairs beautifully with the cinnamon and nutmeg.
For a boozy twist, add 1 tbsp rum extract to the batter instead—just be sure to use a high-quality extract like McCormick. This variation works especially well when baked fresh and served warm. 🍹
Chocolate Chip Swirl
Add a playful surprise by folding in ½ cup semi-sweet chocolate chips (I love Ghirardelli or Hershey’s Special Dark) into the batter after mixing the dry ingredients.
For a marbled effect, spread half the batter in the pan, sprinkle ¼ cup chocolate chips on top, then add the remaining batter. Swirl gently with a knife before baking. The chocolate melts into pockets of gooey goodness throughout each slice. 🍫
Nutty Crunch Layer
For texture lovers, press ½ cup chopped walnuts or pecans (toasted for extra flavor) into the bottom of the greased pan before pouring in the batter. The nuts add a satisfying crunch that contrasts the cake’s soft crumb.
Toast the nuts in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop finely. This works especially well with the spiced rum variation for a sophisticated dessert. 🌰
Lemon Zest Brightness
Brighten the warm spice flavors by adding 1 tbsp lemon zest (from about 1 large lemon) to the batter. The citrus cuts through the richness while complementing the bananas. Pair with a simple lemon glaze (powdered sugar + lemon juice) for an elegant finish.
This variation is perfect for spring or summer when you want a lighter take on classic banana cake. 🍋
Coconut Flour Adaptation
For a gluten-free option with moisture, replace ½ cup of the all-purpose flour with coconut flour (like Bob’s Red Mill). Since coconut flour absorbs more liquid, reduce the milk by 2 tbsp and add an extra ½ tsp baking soda.
The result is a dense, slightly nutty cake with a unique texture. This version is naturally lower in carbs and pairs well with a dollop of coconut whipped cream. 🥥
Pumpkin Spice Fusion
Transform your banana cake into a seasonal favorite by adding ½ cup pumpkin puree (not pie filling) and 1 tsp pumpkin pie spice to the batter. Reduce the milk by ¼ cup** to balance the extra moisture.
The pumpkin adds natural sweetness and pairs beautifully with the warm spices. This variation is perfect for fall and tastes like a cozy hug in cake form. 🎃

Frequently asked questions
Why does this banana cake stay moist longer than others?
The secret lies in the melted butter (not creamed) and the precise ratio of ripe bananas to milk. America's Test Kitchen found that using 1 cup melted butter and 3 ripe bananas creates a dense, moist crumb that stays tender for days. The warm spices also help retain moisture better than vanilla-only cakes.
Can I use unripe bananas in this recipe?
Not ideal! Unripe bananas lack sweetness and add a starchy texture that makes the cake taste bland. For best results, use bananas with black specks on the peel. If you must use unripe ones, mash them with 1 tbsp lemon juice to mimic ripeness, but expect slightly less flavor. The recipe counts on ripe bananas for that signature caramelized sweetness.
What's the difference between this cake and traditional banana cake?
This version uses a spiced warm blend (cinnamon, nutmeg, allspice) instead of just cinnamon, and the melted butter creates a denser crumb. Traditional recipes often use buttermilk or yogurt, but this one relies on ripe bananas and milk for moisture. The baking time is also shorter (50-55 minutes) to prevent dryness.
How do I fix a cake that's too dry?
If your cake turns out dry, it likely overbaked or used underripe bananas. For future attempts, check doneness at 45 minutes and use a toothpick test. To revive a dry cake, slice it and microwave for 10-15 seconds with a damp paper towel on top. For extra moisture, brush warm slices with simple syrup (equal parts sugar and water, heated until dissolved).
Can I make this cake in a different pan size?
Yes, but adjust baking time. For an 8-inch round pan, bake 40-45 minutes (cake will be thicker). For a 9x13-inch pan, reduce oven temp to 325°F and bake 35-40 minutes. Always use a light-colored metal or glass pan—dark pans can overbrown the cake. The key is to bake until the center reaches 205°F internally.
