Banana Pudding Layer Cake

All the cozy, creamy magic of classic banana pudding, stacked tall into a showstopping layer cake with fluffy vanilla cake, silky banana custard cream, and a crown of crushed Nilla wafers.

If banana pudding is the dessert that shows up at every family cookout and church potluck, then this Banana Pudding Layer Cake is its dressed-up, dinner-party-ready cousin.

This cake is the perfect centerpiece for birthdays, summer cookouts, baby showers, or honestly any occasion where you want to absolutely blow everyone away.

Ingredients

For the Vanilla Cake Layers

3 cups all-purpose flour

2 teaspoons baking powder

1/2 teaspoon baking soda

1/2 teaspoon salt

1 cup (2 sticks) unsalted butter, softened

2 cups granulated sugar

4 large eggs, room temperature

2 teaspoons pure vanilla extract

1 cup whole buttermilk, room temperature

For the Banana Pudding Filling

3/4 cup granulated sugar

1/4 cup cornstarch

1/4 teaspoon salt

2 1/2 cups whole milk

4 large egg yolks

2 tablespoons unsalted butter

1 1/2 teaspoons vanilla extract

1/2 teaspoon banana extract

3 ripe bananas, thinly sliced

For the Whipped Cream Cheese Frosting

8 oz cream cheese, softened

2 cups heavy whipping cream, cold

1 1/2 cups powdered sugar, sifted

1 teaspoon vanilla extract

For Garnish

2 cups Nilla wafer cookies (whole and crushed)

2 ripe bananas, sliced (for decorating)

1 tablespoon lemon juice (to prevent browning)

Substitutions and Variations

No buttermilk? Stir 1 tablespoon of white vinegar or lemon juice into 1 cup of regular whole milk. Let it sit for 5 minutes before using.

Shortcut filling: Swap the homemade pudding for 2 boxes of instant banana pudding (3.4 oz each) made with whole milk. It won't be as rich, but it still tastes amazing.

Gluten-free version: Use a 1:1 gluten-free baking flour blend and swap Nilla wafers for gluten-free vanilla cookies. The texture will be slightly denser but still delicious.

Add a caramel drizzle: For extra indulgence, drizzle warm salted caramel sauce between each layer before stacking.

Chocolate twist: Add 1/2 cup of mini chocolate chips to the pudding filling for a banana-chocolate combo that is truly irresistible.

Frosting swap: If you prefer a sweeter finish, use classic vanilla buttercream instead of the whipped cream cheese frosting.

Step-by-Step Instructions

Make the Banana Pudding Filling

Whisk together the sugar, cornstarch, and salt in a medium saucepan. Gradually whisk in the milk until smooth. Place over medium heat and stir constantly until the mixture begins to thicken and bubble, about 8 to 10 minutes. In a separate bowl, lightly whisk the egg yolks. Slowly ladle about 1/2 cup of the hot milk mixture into the yolks while whisking rapidly (this tempers the eggs and prevents scrambling). Pour the egg mixture back into the saucepan and cook for 2 more minutes, stirring constantly. Remove from heat and stir in the butter, vanilla extract, and banana extract. Press plastic wrap directly onto the surface of the pudding and refrigerate for at least 2 hours until fully chilled and set.

Prep Your Pans and Oven

Preheat your oven to 350 degrees Fahrenheit. Grease three 8-inch round cake pans thoroughly with butter or baking spray. Line the bottoms with parchment paper circles, then grease the parchment too. This double-layer prep ensures your cakes release cleanly and come out in perfect shape. Having all three pans ready before you start mixing saves you from scrambling mid-batter.

Mix the Dry Ingredients

In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly combined. This step only takes a minute but it is important for even leavening throughout each layer. Set the dry bowl aside.

Cream Butter and Sugar

In the bowl of a stand mixer (or a large bowl with a hand mixer), beat the softened butter and granulated sugar together on medium-high speed for 4 to 5 full minutes. You want the mixture to look noticeably lighter in color and feel fluffy and airy. This step is the foundation of a tender cake, so don't rush it. Scrape the sides and bottom of the bowl halfway through.

Add the Eggs and Vanilla

Add the eggs one at a time to the butter mixture, beating well after each addition. Scrape down the bowl after every other egg. Once all four eggs are incorporated, add the vanilla extract and mix for another 30 seconds. The batter should look smooth and creamy at this point.

Alternate Dry and Buttermilk

With the mixer on low, add the dry ingredients in three additions, alternating with the buttermilk in two additions (dry, buttermilk, dry, buttermilk, dry). Begin and end with the flour mixture. Mix only until just combined after each addition -- overmixing at this stage develops the gluten and makes the cake tough. A few small streaks of flour are totally fine; they'll work out.

Bake the Cake Layers

Divide the batter evenly among the three prepared pans (a kitchen scale makes this effortless -- about 560 grams per pan). Smooth the tops with an offset spatula. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean and the edges are just beginning to pull away from the pan. Let the cakes cool in the pans for 15 minutes, then turn them out onto wire racks and cool completely -- at least 1 hour.

Make the Whipped Cream Cheese Frosting

Beat the softened cream cheese on medium speed until completely smooth and lump-free, about 2 minutes. Add the powdered sugar and vanilla and beat again until fluffy. With the mixer running on medium-high, pour in the cold heavy cream in a slow, steady stream. Continue whipping until the frosting is thick, glossy, and holds stiff peaks -- about 3 to 4 minutes. Do not overwhip or the frosting can curdle. Keep refrigerated until you are ready to assemble.

Level and Layer the Cakes

If your cake layers have domed tops, use a long serrated knife to level them flat. Place the first cake layer on your serving plate or cake board. Spread a generous, even layer of chilled banana pudding filling over the top (about 1/2 cup), leaving a 1/2-inch border around the edge. Arrange a single layer of banana slices over the pudding. Repeat with the second layer. Then set the third cake layer on top, bottom side up, for the flattest possible surface.

Apply the Crumb Coat

Spread a very thin, even layer of frosting over the entire outside of the cake -- top and sides. This "crumb coat" traps all the loose crumbs and gives you a clean base for the final frosting layer. Don't worry about it looking perfect; it just needs to be thin and cover everything. Refrigerate the crumb-coated cake for 30 minutes until the coating is firm to the touch.

Frost and Decorate

Apply the remaining frosting to the top and sides of the cake in a generous, swoopy layer. Use a bench scraper to smooth the sides and an offset spatula for the top. Press crushed Nilla wafers onto the sides of the cake while the frosting is still soft. Arrange whole Nilla wafers and banana slices (tossed in a little lemon juice to prevent browning) across the top for a gorgeous, classic presentation. Refrigerate for at least 30 minutes before slicing.

Slice and Serve

Run a long sharp knife under hot water, wipe it dry, and slice the cake in one clean downward motion. Wiping the blade between slices keeps every piece looking beautiful. Serve immediately or keep refrigerated until ready to serve. This cake is best enjoyed within the first two days while the bananas are still fresh and the Nilla wafers are at their perfect slightly-softened texture.

Baker's Tips for Success

Room temperature matters: Cold butter won't cream properly, and cold eggs can cause the batter to curdle. Set your dairy and eggs out at least 1 hour before you start baking.

Use very ripe bananas: The spottier the banana, the sweeter and more flavorful your filling will be. Barely-yellow bananas taste bland inside a cake.

Make it ahead: The pudding filling can be made up to 2 days in advance. The baked cake layers can be wrapped in plastic and kept at room temperature for 1 day, or frozen for up to 1 month.

Don't skip the crumb coat: It seems like an extra step, but it is the single biggest thing you can do to get a clean, professional-looking final frosting job.

Pudding border trick: Pipe a ring of frosting around the edge of each cake layer before adding the pudding filling. This acts as a dam to prevent the filling from squeezing out the sides when you stack the layers.

Chill your mixing bowl: For the whipped cream cheese frosting, chill your mixer bowl and whisk attachment in the freezer for 15 minutes before whipping. Cold tools help the cream whip faster and hold its shape longer.

Storage and Reheating

Refrigerator: Store the assembled cake covered loosely with plastic wrap or a cake dome in the refrigerator for up to 3 days. Because of the fresh banana slices and dairy-based filling, this cake must be kept cold.

Best within 2 days: The banana slices inside the cake will start to brown and soften noticeably after day two. The cake is still safe to eat on day three, but the texture is best in the first 48 hours.

Freezing slices: You can freeze individual slices without the banana garnish for up to 1 month. Wrap each slice tightly in plastic wrap, then in foil. Thaw overnight in the refrigerator.

Do not freeze the whole assembled cake: Freezing a fully decorated cake with fresh bananas will result in watery, mushy layers once thawed. It is not recommended.

Serving from cold: Let refrigerated slices sit at room temperature for 15 to 20 minutes before serving. This softens the frosting slightly and brings the flavors forward for the best eating experience.

Serving Suggestions

This cake is a total showstopper on its own, but a few thoughtful additions can take it from delicious to completely unforgettable. Whether you are serving it at a fancy dinner or a backyard cookout, here are some ideas to round out the experience:

A small scoop of vanilla bean ice cream alongside each slice is an absolute dream combination -- the cold creaminess pairs perfectly with the soft cake layers.

Drizzle warm salted caramel or hot fudge sauce right over the plate before placing the slice for a restaurant-worthy dessert presentation.

A freshly brewed cup of coffee or a tall glass of cold milk is the classic companion to any banana pudding dessert, and this cake is no exception.

For a brunch spread or dessert bar, cut the cake into petite finger slices and arrange on a platter with fresh strawberries and a bowl of extra whipped cream for dipping.

Garnish individual plates with a sprinkle of crushed Nilla wafer crumbs and a single banana slice right before serving for a polished, cohesive look.

Frequently Asked Questions

Can I use boxed cake mix instead of making the cake from scratch?

Absolutely. A quality white or vanilla box cake mix works well here and shaves significant time off the process. Just bake it in three 8-inch rounds as directed, and pair it with the homemade pudding filling and frosting from this recipe. The scratch cake does have a noticeably more tender, rich crumb, but a box mix is a perfectly valid shortcut for a weeknight bake.

Will the bananas inside the cake turn brown?

Yes, over time the banana slices inside the filling will oxidize and darken. This is completely normal and does not affect the taste at all -- it is purely cosmetic. To slow this down, slice the bananas right before assembly, and if you like, you can very lightly toss them in a squeeze of lemon juice. For the decorative banana slices on top, toss those in lemon juice for sure, and decorate as close to serving time as possible.

Can I make this as a two-layer cake instead of three?

Yes, and it is a great option if you prefer a less tall cake or only have two pans. Simply divide the batter between two 9-inch round pans and increase the baking time by about 5 minutes. You will have extra pudding filling, which can be served on the side as a dip for Nilla wafers -- nobody will complain about that.

My pudding filling came out lumpy. What went wrong?

Lumpy pudding usually means the egg yolks were added too quickly to the hot milk mixture, causing them to scramble slightly. The fix is easy: pour the warm pudding through a fine-mesh strainer and press it through with a spatula. This removes any bits and leaves you with a perfectly silky, smooth custard. Next time, just be sure to add the hot liquid to the yolks very slowly and whisk constantly the whole time.

How far in advance can I assemble the fully decorated cake?

You can fully assemble and frost the cake up to 24 hours in advance -- just hold off on adding the fresh banana garnish on top until a few hours before serving. Keep the assembled cake refrigerated and covered. This actually helps the layers settle and the pudding filling firm up, making for cleaner, more beautiful slices.
