Moist Banana Pudding Pound Cake with Vanilla Wafers
This banana pudding pound cake captures everything you love about the classic Southern dessert in one dense, buttery loaf. The vanilla wafer crust on top gives you that familiar crunch, and the pudding mix keeps the inside tender for days.
It comes together with a box of instant pudding and a couple of ripe bananas, so it’s simple enough for a weeknight bake. The kitchen smells like warm bananas and vanilla while it’s in the oven.
What Makes This Pound Cake So Good
The instant banana cream pudding mix does the heavy lifting. It delivers that nostalgic banana flavor and locks in moisture so every slice stays soft, with no dry corners.
The crushed vanilla wafer topping is the best part. It toasts up golden and crisp while the cake bakes, mimicking the Nilla wafers in classic banana pudding. The texture stays dense but never heavy, with a thick, crackly top.
I keep coming back to this recipe because it’s a reliable loaf that travels well and doesn’t need frosting. A slice is sweet enough on its own, but a quick zap in the microwave makes it taste fresh from the oven.
Ingredients
- 1 box (3.4 oz) instant banana cream pudding mix: the key flavor and moisture source
- ½ cup unsalted butter, softened: gives the tender crumb
- 1 cup granulated sugar: sweetness balanced with the ripe bananas
- 2 large eggs, room temperature: brings the batter together
- 1 tsp vanilla extract: rounds out the banana taste
- 1½ cups all-purpose flour: measured by spoon-and-level method
- ½ tsp baking powder: a little lift so it’s not brick-like
- ¼ tsp baking soda: helps with browning
- ½ tsp salt: cuts the sweetness
- ½ cup sour cream: adds richness and tang
- 2 ripe bananas, mashed (about 1 cup): use ones with plenty of brown spots
- ½ cup crushed vanilla wafers: for the crunchy top
- 2 tbsp unsalted butter, melted: to mix with the wafers
Variations / Substitutions
- Use a different pudding flavor: a cheesecake or vanilla pudding mix works if you’re out of banana cream, though the banana taste will be milder.
- Yogurt for sour cream: plain full-fat Greek yogurt keeps the same moisture level.
- Add nuts: fold ½ cup chopped pecans or walnuts into the batter and skip the wafer topping for a nutty crunch.
- Go gluten-free: swap the flour for a measure-for-measure gluten-free baking blend; the texture will be slightly more delicate.

How to Make Banana Pudding Pound Cake
Step 1: Cream the Butter and Sugar
Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan, then line it with parchment so the cake lifts out cleanly. In a large bowl, beat the ½ cup softened butter and 1 cup sugar together for about 3 minutes with a hand mixer, until the mixture looks pale and fluffy.
The butter will lighten in color and the sugar will start to dissolve. Scrape the bowl halfway through so no streaks hide at the bottom.
Step 2: Mix the Wet Ingredients
Beat in the 2 eggs one at a time, mixing well after each. Then add the 1 tsp vanilla extract and the box of dry pudding mix; beat just until combined, about 30 seconds. Pour in the ½ cup sour cream and fold it in gently with a spatula.
The batter will turn a soft yellow and smell heavily of bananas. At this stage, it’s thick, so the mashed bananas will loosen it up in the next step.
Step 3: Add the Dry Ingredients and Bananas
Whisk together the 1½ cups flour, ½ tsp baking powder, ¼ tsp baking soda, and ½ tsp salt in a separate bowl. Add the dry mixture to the wet mixture in two additions, folding just until you see no more flour streaks. Fold in the mashed bananas last, and stop as soon as the streaks disappear.
The batter will be lumpy from the bananas, which is exactly right. Overmixing here can make the loaf tough, so a few gentle folds are all you need.
Step 4: Top and Bake
Scrape the batter into the prepared pan and smooth the top. In a small bowl, toss the ½ cup crushed vanilla wafers with the 2 tbsp melted butter. Scatter this mixture evenly over the batter, pressing it down very lightly so it sticks. Bake for 55 to 65 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
The top will turn deep golden and the wafers will smell toasty. If the crust gets dark before the center sets, tent the pan loosely with foil for the last 15 minutes. A slight crack down the middle is normal for a pound cake.
Step 5: Cool and Slice
Let the cake cool in the pan on a wire rack for 10 minutes. Lift it out by the parchment and let it cool completely on the rack, about an hour. Slice with a serrated knife and serve.
The crumb will be moist and amber inside, with a crunchy wafer lid that shatters a little as you cut. This cake holds together beautifully once it’s fully cool.
Tips for the Perfect Pound Cake
- Use very ripe bananas. The peels should be heavily speckled or mostly brown. Underripe bananas won’t give you enough moisture or sweetness.
- Don’t skip the parchment. The wafer topping can stick to the pan, so parchment handles make lifting foolproof.
- Check early with glass pans. If you bake in a glass loaf pan, start checking at the 50-minute mark because glass holds heat differently.
- Let it cool before slicing. Cutting into a warm pound cake will make it crumble; the crumb sets as it cools.
Bake times by pan:
| Pan type and size | Bake time |
|---|---|
| 9×5-inch metal loaf pan | 55-65 mins |
| 8.5×4.5-inch glass loaf pan | 60-70 mins |
| 8×4-inch metal loaf pan (will be quite full) | 65-75 mins |
Storing Leftover Cake
- Refrigerate: wrapped tightly in plastic or in an airtight container for up to 5 days.
- Reheating: a slice in the microwave for 15 seconds softens the crumb and makes it taste just-baked.
- Serve cold: it’s delicious straight from the fridge with coffee.
What to Serve with Banana Pudding Pound Cake
A slice of this cake sits well on its own, but a dollop of lightly sweetened whipped cream echoes the creamy notes of banana pudding. A scoop of vanilla bean ice cream on warm cake makes a quick dessert feel special. For brunch, offer slices alongside fresh berries and black coffee to balance the sweetness.
Frequently Asked Questions
Can I skip the pudding mix and use more bananas?
No. The dry pudding mix is what gives the cake its signature banana pudding taste and ultra-soft texture. Relying on extra bananas alone won’t replicate it.
How do I keep the wafer topping from burning?
It shouldn’t burn with a 350°F bake, but if your oven runs hot, tent the top loosely with a sheet of foil during the final 15 minutes. That slows the browning without steaming the crust.
Can I make this cake gluten-free?
Yes. Use a measure-for-measure gluten-free flour blend that contains xanthan gum. The loaf will be slightly more tender but still sliceable.
Why did my cake sink in the middle?
It likely needed a few more minutes in the oven. A sunken center usually means the batter was still too wet when you pulled it. Next time, test with a toothpick and don’t open the oven door until at least 50 minutes have passed.
