Ingredients

For the Moist Banana Cake

• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/2 teaspoon kosher salt
• 1/2 teaspoon ground cinnamon
• 1/2 cup unsalted butter, softened
• 3/4 cup packed light brown sugar
• 1/2 cup granulated sugar
• 2 large eggs, room temperature
• 1 1/2 cups mashed very ripe bananas, about 3–4 large bananas
• 1/2 cup buttermilk, room temperature
• 2 teaspoons pure vanilla extract

For the Brown Butter Cream Cheese Frosting

• 3/4 cup unsalted butter
• 8 ounces full-fat block cream cheese, softened
• 3 1/2 cups powdered sugar
• 2 teaspoons pure vanilla extract
• 1/4 teaspoon kosher salt

Optional Toppings

• Chopped toasted pecans
• Chopped walnuts
• Banana chips
• Ground cinnamon
• Caramel drizzle

Instructions

1. Prepare the Oven and Pan

Preheat the oven to 350°F.

Grease a 9×13-inch baking pan and line it with parchment paper, leaving some parchment extending over the sides for easy removal.

Lightly grease the parchment.

2. Combine the Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.

Set aside while you prepare the wet ingredients.

3. Cream the Butter and Sugars

Place the softened butter, brown sugar, and granulated sugar in a large mixing bowl.

Using an electric mixer, beat on medium-high speed for approximately 2–3 minutes, until lighter and creamy.

Scrape down the sides and bottom of the bowl as needed.

4. Add the Eggs

Add the eggs one at a time, beating well after each addition.

Mix in the vanilla extract.

5. Add the Bananas

Add the mashed ripe bananas and mix until combined.

The batter may look slightly separated at this stage, which is normal.

6. Alternate the Dry Ingredients and Buttermilk

With the mixer on low speed, add about one-third of the flour mixture.

Add half of the buttermilk, followed by another third of the flour mixture.

Mix in the remaining buttermilk, then finish with the remaining dry ingredients.

Mix only until combined. Avoid overmixing, which can make the cake dense instead of soft and tender.

7. Fill the Pan

Spread the banana cake batter evenly into the prepared 9×13-inch pan.

Smooth the top with a spatula.

8. Bake

Bake at 350°F for 35–40 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

Begin checking the cake around 33–35 minutes because ovens can vary.

Avoid overbaking—the cake will stay much softer and moister when removed as soon as it’s done.

9. Cool Completely

Place the pan on a wire rack and allow the cake to cool completely before frosting.

Don’t add cream cheese frosting to a warm cake, as it can melt and become runny.

How to Make Brown Butter Cream Cheese Frosting

1. Brown the Butter

Place the butter in a light-colored saucepan or skillet over medium heat.

Let it melt completely.

Continue cooking, stirring or swirling the pan frequently. The butter will foam and then begin developing golden-brown bits on the bottom.

Watch carefully as it changes from golden to amber and develops a toasted, nutty aroma.

Once browned, immediately remove the pan from the heat so the milk solids don’t burn.

2. Cool the Brown Butter

Pour the brown butter, including the flavorful browned bits, into a heat-safe bowl.

Allow it to cool until it begins to solidify but is still soft enough to beat.

You can refrigerate it briefly to speed up the process, but check it frequently so it doesn’t become completely hard.

3. Beat the Brown Butter

Transfer the cooled brown butter to a mixing bowl.

Beat with an electric mixer until smooth and creamy.

4. Add the Cream Cheese

Add the softened block cream cheese.

Beat briefly until smooth and combined.

Avoid excessive mixing once the cream cheese is added, as overbeating can make cream cheese frosting softer.

5. Add the Powdered Sugar

With the mixer on low speed, gradually add the powdered sugar.

Continue mixing until incorporated.

6. Add Vanilla and Salt

Add the vanilla extract and salt.

Beat briefly until the frosting is smooth, creamy, and spreadable.

If the frosting feels too soft, refrigerate it for approximately 15–30 minutes before using.

Frost the Banana Cake

Once the banana cake is completely cool, spread the brown butter cream cheese frosting evenly over the top.

Use an offset spatula or the back of a spoon to create decorative swirls.

For extra texture, sprinkle the top with toasted pecans or walnuts.

You can also finish the cake with banana chips, a light dusting of cinnamon, or a drizzle of caramel sauce.

Slice into squares and serve.

Tips for the Best Moist Banana Cake

Use very ripe bananas. Bananas covered with plenty of brown or black spots are sweeter, softer, and more flavorful than yellow bananas.

Measure the mashed banana. Banana sizes vary considerably. Measuring approximately 1 1/2 cups gives more consistent results than relying only on the number of bananas.

Measure flour correctly. Spoon the flour into the measuring cup and level it with a knife. Scooping directly from the flour container can pack too much flour into the cup and make the cake dry.

Use room-temperature ingredients. Butter, eggs, and buttermilk combine more evenly when they’re close to room temperature.

Don’t overmix. Once you begin adding the flour, mix only until everything is incorporated.

Don’t overbake. Overbaking can quickly turn a wonderfully moist banana cake dry.

Watch the brown butter carefully. Once the milk solids begin browning, butter can go from perfectly toasted to burned very quickly.

Cool the brown butter before making the frosting. Warm butter can melt the cream cheese and produce runny frosting.

How Ripe Should Bananas Be for Banana Cake?

The best bananas for baking are much riper than the bananas most people prefer for snacking.

Look for bananas with heavily spotted brown skins or skins that have become mostly brown or black.

As bananas ripen, their starches convert into sugars, giving baked goods more natural sweetness and stronger banana flavor.

Avoid using firm green or barely ripe bananas if possible.

How to Quickly Ripen Bananas for Baking

If your bananas aren’t quite ripe enough, place the unpeeled bananas on a baking sheet and bake them at 300°F until the skins become dark and the fruit inside softens, usually around 15–30 minutes depending on ripeness.

Let them cool before peeling and mashing.

This method softens and sweetens the bananas, although naturally overripe bananas generally provide the best flavor.

Why Brown Butter Makes the Frosting Better

Regular butter is delicious, but browning it adds another layer of flavor.

As butter cooks, its milk solids toast and develop rich caramelized, nutty notes. Those flavors complement banana cake especially well.

Combining brown butter with tangy cream cheese creates a frosting that’s rich without tasting one-dimensional or overly sweet.

Be sure to scrape all the little browned milk solids from the pan into your mixing bowl—that’s where much of the toasted flavor comes from.

Easy Variations

Banana Cake With Walnuts

Fold 3/4 cup chopped walnuts into the batter before baking.

Sprinkle additional toasted walnuts over the frosting.

Banana Pecan Cake

Add 3/4 cup chopped pecans to the cake batter and decorate the finished cake with toasted pecans.

Banana Chocolate Chip Cake

Fold 1 cup semisweet chocolate chips into the batter before transferring it to the baking pan.

Banana Caramel Cake

Drizzle caramel sauce over the cream cheese frosting immediately before serving.

A small sprinkle of flaky salt can provide a delicious sweet-and-salty finish.

Banana Cupcakes

Divide the batter among lined muffin cups, filling each approximately two-thirds full.

Bake at 350°F for about 18–22 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

Cool completely before adding the brown butter cream cheese frosting.

Can I Make This as a Layer Cake?

Yes.

Divide the batter evenly between two greased and parchment-lined 9-inch round cake pans.

Because layer cakes may bake faster than a 9×13-inch cake, begin checking them around 25 minutes.

They’re done when a toothpick inserted into the center comes out clean or with a few moist crumbs.

Cool the layers completely before assembling them with the brown butter cream cheese frosting.

What to Serve With Banana Cake

This cake is delicious on its own, but you can make individual servings extra special with:

• Fresh banana slices
• Vanilla ice cream
• Caramel sauce
• Toasted pecans
• Toasted walnuts
• Fresh strawberries
• Whipped cream
• Hot coffee
• Cold milk

If decorating with fresh banana slices, add them immediately before serving because cut bananas will brown over time.

Make-Ahead Instructions

The banana cake can be baked a day ahead.

Once completely cooled, cover the unfrosted cake tightly and keep it at room temperature overnight.

You can also prepare the brown butter ahead of time and refrigerate it. Allow it to soften before preparing the frosting.

Once frosted with cream cheese frosting, keep the cake refrigerated.

Storage

Because this banana cake is topped with cream cheese frosting, store leftovers covered in the refrigerator.

The cake will keep well for up to 5 days.

For the softest texture and fullest flavor, allow individual slices to sit at room temperature for approximately 20–30 minutes before serving.

Avoid leaving cream cheese-frosted cake at room temperature for extended periods.

Can You Freeze Banana Cake?

Yes. Banana cake freezes very well.

Unfrosted Cake

Allow the cake to cool completely.

Wrap it tightly in plastic wrap followed by aluminum foil and freeze for up to 3 months.

Thaw overnight in the refrigerator before frosting.

Frosted Cake

You can also freeze individual frosted slices in airtight freezer-safe containers.

Thaw them overnight in the refrigerator before serving.

Frequently Asked Questions

What makes banana cake moist?

Ripe bananas naturally contribute moisture, while butter, brown sugar, eggs, and buttermilk help create a soft and tender cake.

Can I use frozen bananas?

Yes. Thaw frozen ripe bananas completely and drain off excessive watery liquid before mashing and measuring them.

Can I use regular milk instead of buttermilk?

Buttermilk is recommended for the best flavor and texture. If necessary, add 1 1/2 teaspoons of lemon juice or white vinegar to a measuring cup, then add enough milk to reach 1/2 cup. Let it stand for 5–10 minutes before using.

What’s the difference between banana cake and banana bread?

Banana cake is generally lighter, softer, and sweeter, while banana bread tends to have a denser, sturdier quick-bread texture. Banana cake is also commonly finished with frosting.

Why did my banana cake turn out dense?

Overmixing the batter, adding too much flour, or using an excessive amount of banana can make the cake heavier than intended.

Why is my cream cheese frosting runny?

The brown butter may have been too warm, the cream cheese may have been overly soft, or the frosting may have been beaten for too long. Refrigerate the frosting for 15–30 minutes to help it firm up.

Can I make this recipe without nuts?

Absolutely. Nuts are completely optional and can simply be omitted without making other changes to the recipe.
