No-Bake Banana Pudding Cake with Vanilla Wafer Layers
Banana pudding cake is the no-bake dessert that turns classic Southern banana pudding into something you can slice and serve on a plate. It looks like a proper layer cake, but there’s zero oven time involved.
Layers of vanilla wafers soften into tender sheets, holding thick banana pudding and fresh bananas between them. A little cream cheese and sweetened condensed milk make the filling rich and sliceable, so every piece comes out clean and loaded with flavor.
Why This No-Bake Banana Pudding Cake Works
All the creamy, nostalgic banana flavor you love lives right here, no bowl of mush in sight. The wafers absorb moisture overnight and turn into a soft, cakelike crumb that holds its shape.
I keep coming back to this because it’s made ahead with mostly pantry ingredients. It shows up to a potluck looking like you worked a lot harder than you actually did.
Ingredients
- 11 oz box vanilla wafers: Nabisco or a similar crisp wafer; you’ll use almost the whole box.
- 2 (3.4 oz) boxes instant vanilla pudding mix: cook-and-serve will not set up correctly here.
- 3 cups whole milk: cold, right from the fridge.
- 8 oz cream cheese, softened: use the block kind, not a tub of spread.
- 1 can (14 oz) sweetened condensed milk: the thick, sticky one.
- 12 oz frozen whipped topping (like Cool Whip), thawed: measured after thawing.
- 4 to 5 ripe but firm bananas: sliced into 1/4-inch rounds.
- 1 tsp vanilla extract: optional, but it rounds out the creamy notes.
Variations / Substitutions
- Use banana cream pudding: swap both boxes for instant banana cream pudding to push the banana flavor even further.
- Lighter dessert: swap in reduced-fat cream cheese, light whipped topping, and 2% milk; the cake will still set firmly.
- Caramel layer: drizzle a thin layer of warmed caramel sauce over the banana slices before adding the next wafer layer.
- Peanut butter swirl: drop small spoonfuls of creamy peanut butter into the pudding mixture and fold just once or twice so it marbles through.

How to Make No-Bake Banana Pudding Cake with Vanilla Wafer Layers
Step 1: Beat the Pudding Base
In a large bowl, beat the 2 boxes of instant pudding mix with the 3 cups of cold milk until the mixture thickens noticeably, about 2 minutes. Set it aside for 5 minutes so it can set up further while you work on the cream cheese.
In a second bowl, beat the 8 oz softened cream cheese until smooth, then slowly pour in the 14 oz sweetened condensed milk and 1 tsp vanilla. Keep beating until the mixture is silky and lump-free. Scrape it all into the pudding bowl and beat for another 30 seconds until they are completely combined.
Step 2: Fold in the Whipped Topping
Add the thawed 12 oz whipped topping to the bowl. Use a flexible spatula to fold it in by cutting down through the center and scraping around the sides, repeating until no white streaks are left, about 1 minute.
The filling will be thick and mousse-like. Fold slowly and deliberately so you don’t knock the air out. Aggressive stirring makes a denser, less tender cake after chilling.
Step 3: Layer the Cake
Cover the bottom of a 9×13-inch dish with a single layer of vanilla wafers, flat side down. Spoon half of the pudding mixture over the wafers and use an offset spatula to spread it evenly from corner to corner. Arrange a single layer of sliced bananas on top, tucking them close together.
Add another layer of wafers on top of the bananas, pressing gently so they stay put. Spread the remaining pudding mixture over them, then finish with a final neat layer of wafers on the surface. Crush a few extra wafers to sprinkle over the top later if you like.
Step 4: Chill and Slice
Cover the dish tightly with plastic wrap and refrigerate for at least 6 hours, or overnight. The wafers need that time to absorb moisture and transform into soft, cakelike layers that slice cleanly.
When you’re ready to serve, run a thin knife around the edges to loosen. Cut the cake into squares and use a flat spatula to lift each piece onto plates. Serve it cold, with an extra dollop of whipped topping and a few crushed wafers scattered over the top.
A Few Tips for Perfect Layers
- Choose firm-ripe bananas: you want them sweet and yellow with maybe a few brown specks, but still firm. Overripe fruit will turn mushy and watery.
- Chill it overnight if you can: the wafers hit the ideal soft-yet-structured texture after about 12 hours. Six hours works, but overnight is better.
- Do not use cook-and-serve pudding mix: instant is the only kind that sets up without heat, and it’s what gives the filling its thick, stable body.
- For the cleanest slices: dip a sharp knife in hot water and wipe it dry between each cut.
Scale it to your dish size:
| Dish Size | Servings | Ingredient Adjustment |
|---|---|---|
| 8×8 inch | 6 to 8 | Halve all ingredients; use 2 to 3 bananas |
| 9×13 inch | 12 | Recipe as written |
| 11×15 inch | 18 to 20 | Double all ingredients; use 8 to 10 bananas |
Keeping Banana Pudding Cake Fresh
- Refrigerate: keep the dish covered tightly with plastic wrap or a lid. It stays good in the fridge for up to 3 days. The bananas may darken a little around the edges, but the flavor holds.
- Serve cold: this cake is meant to be eaten straight from the fridge. Letting it sit out too long softens the filling and makes it harder to slice neatly.
Frequently Asked Questions
Can I use homemade whipped cream instead?
Yes, but it can weep liquid as it sits. If you go homemade, stabilize the cream with a tablespoon of powdered sugar and a little cornstarch, then fold gently.
What if I use banana pudding mix instead of vanilla?
You can swap both boxes of vanilla for instant banana cream pudding one for one. The banana taste will be more intense, and the color a bit more yellow.
How far ahead can I assemble the cake?
You can make it up to 24 hours in advance. After that, the wafers start to cross the line from tender to mushy, so aim for the day before.
My cake came out runny. What went wrong?
You likely used cook-and-serve pudding or didn’t chill it long enough. The filling must be made with instant pudding mix, and the assembled cake needs at least 6 hours in the fridge to set.
Can I freeze leftover cake?
Freezing is not recommended. The pudding and bananas release water when thawed, leaving you with a watery mess.
