Save to Pinterest This stunning Southern dessert combines the best of two beloved treats—banana cake and banana pudding—into one unforgettable creation. Three layers of incredibly moist banana cake are sandwiched between clouds of creamy vanilla pudding filling, with fresh sliced bananas and buttery vanilla wafers adding perfect texture contrasts throughout.
The magic happens when these elements come together: the cake stays tender from ripe mashed bananas, while the pudding mixture—enriched with whipped cream—creates an irresistibly smooth, velvety filling. After chilling for at least two hours, the flavors meld beautifully, making each bite a perfect balance of sweet banana, warm vanilla, and satisfying crunch from the wafer cookies.
Perfect for potlucks, holidays, or anytime you need a dessert that feeds a crowd, this showstopping cake serves twelve generously and tastes even better the next day.
The smell of bananas browning on the kitchen counter used to drive my grandmother absolutely mad until she figured out they were her secret weapon for the most requested dessert at every church potluck we ever attended.
My cousin David once stood guard in front of the refrigerator at Thanksgiving threatening anyone who tried to cut into this cake before dinner was officially over.
Ingredients
- All purpose flour (2 cups): Spoon and level it rather than scooping directly from the bag to avoid dense, heavy layers.
- Baking powder and baking soda (1 1/2 tsp and 1/2 tsp): Check expiration dates because old leavening is the silent killer of good cake.
- Salt (1/2 tsp): Just enough to make the sweetness sing without tasting salty.
- Unsalted butter, room temperature (1/2 cup): Leave it out for an hour so it creams properly with the sugar and traps air into the batter.
- Granulated sugar (1 cup): Standard white sugar works best here since brown sugar would shift the flavor away from clean banana.
- Large eggs (2): Room temperature eggs blend more evenly into the creamed butter mixture.
- Vanilla extract (1 tsp): Use the real stuff, not imitation, because this cake depends on warm, honest flavors.
- Buttermilk (1/2 cup): The tang tenderizes the crumb and reacts with baking soda for lift.
- Ripe bananas, mashed (3 large, about 1 1/2 cups): The speckled, nearly embarrassing ones on your counter are exactly what you need for sweetness and moisture.
- Instant vanilla pudding mix (1 package, 3.4 oz): This shortcut ingredient is the bridge between cake and pudding that makes the whole concept work.
- Cold milk (2 cups): Cold liquid helps the pudding set quickly and firmly.
- Heavy cream, whipped (1 cup for pudding, 1 cup for topping): Whipping your own takes five minutes and tastes infinitely better than anything from a tub.
- Bananas, sliced (2 large): A quick squeeze of lemon juice keeps them bright and appetizing until serving.
- Vanilla wafer cookies, roughly crushed (1 1/2 cups): Leave some bigger pieces for texture contrast against the soft pudding.
Instructions
- Get the oven ready:
- Preheat to 350 degrees F and grease two 9 inch round pans with butter then dust them with flour, tapping out the excess over the sink.
- Build the dry mix:
- Whisk the flour, baking powder, baking soda, and salt together in a medium bowl until evenly blended then set it aside.
- Cream the butter and sugar:
- Beat the room temperature butter and sugar in a large bowl until the mixture turns pale yellow and looks almost fluffy like frosting, then add the eggs one at a time followed by the vanilla.
- Fold in the bananas and alternate wet and dry:
- Stir the mashed bananas into the creamed mixture then add the flour in three additions alternating with the buttermilk in two, starting and ending with flour and stirring just until each addition disappears.
- Bake the layers:
- Divide the batter evenly between your prepared pans and smooth the tops with a spatula, then bake for 28 to 32 minutes until a toothpick slid into the center comes out clean.
- Cool the cakes completely:
- Let the cakes rest in their pans for ten minutes then turn them out onto wire racks and wait patiently because warm cake will melt your pudding filling into a soupy mess.
- Make the pudding filling:
- Whisk the pudding mix and cold milk together for two full minutes, let it thicken for five, then gently fold in one cup of whipped cream and chill until you are ready to assemble.
- Assemble the cake:
- Place one cooled layer on your serving platter, spread half the pudding over it, lay down banana slices and a shower of crushed wafers, then set the second layer on top and cover with the remaining pudding.
- Finish and chill:
- Pile the remaining whipped cream on top, scatter the last of the bananas and wafers over everything, and refrigerate for at least two hours so the flavors settle and the layers hold together when sliced.
Save to Pinterest The summer my grandmother was too tired to make her usual banana pudding from scratch she accidentally invented this cake by dumping everything into pans instead of a trifle bowl and nobody was even slightly disappointed.
What to Know About the Tools
You do not need anything fancy beyond two matching cake pans and a mixing bowl but an offset spatula makes spreading the pudding feel effortless rather than clumsy.
When Things Go Sideways
If your cakes dome in the oven just slice the tops off with a serrated knife before assembling because flat layers stack evenly and nobody sees the evidence anyway.
Getting It to the Table
Transport this cake already chilled and keep it level in the car because a tilted pudding cake is a sad thing to carry through someones front door.
- Use a large flat spatula and a steady hand for serving clean slices.
- Leftovers hold beautifully in the fridge for up to three days covered loosely with foil.
- Always serve this cold because room temperature pudding turns weepy and sad.
Save to Pinterest Every time I make this cake I think of my grandmother humming in her kitchen with flour on her apron, and somehow it always tastes like she is still here.
Recipe FAQ
- → How long does banana pudding cake need to chill before serving?
-
Chill the assembled cake for at least 2 hours before serving. This allows the pudding to set properly and the flavors to meld together beautifully. For even better results, refrigerate overnight—the cake develops a more cohesive texture and the banana flavor intensifies.
- → Can I prevent the sliced bananas from turning brown?
-
Yes! Toss the sliced bananas in a little lemon juice before arranging them on the cake layers. The acid helps prevent oxidation and keeps the bananas looking fresh and appetizing. You can also assemble the cake shortly before serving to minimize browning.
- → Can I make this cake in advance?
-
Absolutely! This cake actually tastes better when made a day ahead. The pudding has time to soften the cake layers slightly, creating a more cohesive texture. Store it covered in the refrigerator for up to 2-3 days. Add the final banana garnish closer to serving time for the freshest appearance.
- → Can I use homemade pudding instead of instant?
-
Definitely! Homemade vanilla pudding made from scratch will give you an even richer, more custard-like flavor. Just be sure to cool it completely before folding in the whipped cream and assembling the cake. Cook-and-serve pudding packets work wonderfully too if you want something in between.
- → What's the best way to store leftovers?
-
Cover the cake tightly with plastic wrap or transfer to an airtight container and refrigerate. The pudding and cream components require cold storage. Properly stored, it will keep well for 2-3 days, though the wafers will soften over time—some people actually prefer this texture!
- → Can I freeze banana pudding cake?
-
Freezing isn't recommended because the pudding filling and whipped cream don't thaw well—they can separate and become watery. For best results, enjoy this cake fresh from the refrigerator within a few days of assembly.
