Banana Pound Cake — Dense, Golden & Perfectly Southern

Some Sundays call for something that fills the whole kitchen with warmth. Not a quick batch of muffins, not a simple loaf. Something that takes its time and means it. This banana pound cake recipe from scratch is that kind of bake — dense, golden-crusted, and unapologetically Southern. Six whole eggs. A full cup of butter. Two very ripe bananas. No baking powder. No frosting. Just honest, old-fashioned ingredients doing exactly what they’ve done for generations.

This is not banana bread. It’s a true Southern pound cake — slow-baked at 325°F until the outside caramelizes into a thick golden crust, with a tight, velvety crumb inside that banana bread never has. The kind of cake that appears at church potlucks and Sunday dinners, feeds a crowd, and keeps well for days.

If you love a beautiful banana cake for family gatherings, our banana cake with cream cheese frosting is a wonderful everyday version — but this pound cake is something else entirely. This is the one people ask about.

Why You’ll Love This Easy Banana Pound Cake

This recipe has a few things going for it that are worth knowing before you start.

• No baking powder required. The rise comes entirely from creaming air into the butter and six eggs — that’s what gives a true Southern pound cake its signature dense, velvety crumb.
• The sour cream keeps it moist for days. This cake stays tender and soft for 3 full days on the counter. It genuinely tastes better on day 2.
• That caramelized crust needs no frosting. The long, slow bake at 325°F (165°C) creates a thick golden shell that crunches gently when you slice it. It is the entire point of this cake.
• One bowl, one pan. Your stand mixer does all the heavy lifting. Everything goes in order — no special technique, no multiple components.
• Feeds a real crowd. This batter fills a 12-cup bundt pan and yields 14 generous slices. It was built for a table full of people.

Ingredients for This Banana Pound Cake From Scratch

Everything in this recipe is a pantry staple — the magic is in the ratios and technique, not in anything unusual. Here’s what you need and why each one matters.

Wet Ingredients

Unsalted butter (1 cup / 225g), softened. Real butter, fully at room temperature, is non-negotiable. It needs to cream into the sugar and create an emulsion — cold butter simply won’t do it. Set it out at least one hour before you start.

Granulated sugar (3 cups / 600g). Yes, three full cups. This is a traditional Southern pound cake. The sugar is also what creates the beautiful caramelized exterior during the long bake.

Eggs, large (6 whole eggs), room temperature. These are your entire leavening system. Add them one at a time and give each one 30 seconds before the next. Six eggs build the structure, the richness, and the silky crumb this cake is known for.

Ripe bananas (2 medium, about 1 cup / 230g mashed). The more spotted, the better. Ripe bananas bring more natural sweetness and a deeper, more concentrated banana flavor. Trust the brown spots — they’re doing you a favor.

Sour cream (1 cup / 240g), full-fat. This is the key to a truly moist banana sour cream pound cake. The fat keeps the crumb tender for days; its acidity reacts with the small amount of baking soda — not to make the cake rise, but to neutralize and balance. Do not substitute with low-fat versions.

Vanilla extract (1½ tsp). Pure vanilla only.

Lemon extract (½ tsp). Subtle but essential. It brightens the whole cake and balances the richness of the butter and sugar in a way that’s invisible but deeply felt. Don’t skip it.

Dry Ingredients

All-purpose flour (3 cups / 375g). White Lily all-purpose is the Southern baker’s classic choice — lower in protein, more tender crumb. Standard all-purpose works equally well.

Baking soda (¼ tsp). One quarter teaspoon only. This is not here to make the cake rise. It neutralizes the acidity of the sour cream. That is its entire job.

Mix-ins (Optional)

Chopped walnuts (½ cup / 60g). Toast them first for 8 minutes at 350°F (175°C) on a dry baking sheet. They add a warm, slightly bitter note that cuts through the richness. Leave them out for a smoother crumb, or swap for pecans for a deeper Southern flavor. Both make a wonderful banana walnut pound cake or banana nut pound cake depending on your choice.

How to Prepare Your Bundt Pan

Baking spray with flour (or cake goop). Do not sugar the pan. Sugar melts against the metal during the long bake and fuses to the surface, risking a torn cake at unmolding. Use a generous coating of flour-based baking spray, or make cake goop: equal parts softened butter, all-purpose flour, and vegetable oil, blended into a paste and brushed into every groove. Your crust will still be deeply golden and beautiful — and the cake will release cleanly.

How to Make This Southern Banana Pound Cake Recipe

This is a patient recipe — not complicated, but one that rewards you for not rushing. Follow the steps in order, keep your ingredients at room temperature, and the rest takes care of itself.

Step 1 — Preheat and Prep Your Pan (5 min)

Preheat your oven to 325°F (165°C). Grease a 12-cup bundt or tube pan very thoroughly with baking spray and flour, making sure every groove and corner is coated. This is the single most important step for clean unmolding. Set the pan aside.

Step 2 — Cream the Butter, Sugar, and Eggs (10 min)

Cream the softened butter and granulated sugar in a stand mixer fitted with the paddle attachment on medium-high speed for 5 to 7 minutes, stopping halfway to scrape down the bowl. The mixture should be very pale — almost white — and noticeably fluffy. Don’t rush this step. The air you’re incorporating right now is doing all the structural work, since there’s no baking powder in this banana pound cake recipe.

Add the eggs one at a time on medium speed, beating about 30 seconds between each egg. Scrape down the bowl after every two eggs. By the time the sixth egg is in, your batter will look silky, thick, and almost custardy. Be patient — this step builds the emulsion that holds everything together.

Step 3 — Add the Bananas and Sour Cream (5 min)

Mix in the mashed ripe bananas, vanilla extract, and lemon extract on medium until just combined, about 30 seconds. The batter may look slightly curdled at this point — that is completely normal and comes together once the flour goes in.

Combine the sour cream and baking soda in a small bowl, stir, and let sit for 30 seconds — it will puff slightly. Add to the batter and mix on low until fully incorporated.

Step 4 — Fold in the Flour and Walnuts (5 min)

Add the flour in three equal additions on the lowest mixer speed — about 1 cup at a time — mixing just until each disappears. Stop the moment the last streak of flour is gone. Overmixing activates gluten and will give you a dense, gummy crumb instead of a velvety one.

Fold in the toasted chopped walnuts with a rubber spatula by hand, if using.

Step 5 — Bake and Unmold (80 min + 1h rest)

Pour the thick batter into the prepared pan — it will be very full. Smooth the top gently. Bake at 325°F (165°C) for 75 to 85 minutes. The cake is ready when a wooden skewer inserted in the thickest part comes out with just a few moist crumbs — no wet batter.

Cool the pan on a wire rack for 15 to 20 minutes. Run a thin offset spatula around the outer edge and center tube. Place the wire rack upside-down over the pan and flip in one confident motion.

Rest on the rack for at least 1 hour before slicing. The crumb is still setting as it cools. A warm slice will feel gummy; a cooled slice is clean, dense, and perfect.

Lily’s Tips for the Moistest Old-Fashioned Banana Pound Cake

I’ve made this recipe many, many times — and these are the details that actually matter. A few of them seem small. They’re not.

Use the ripest bananas you have, always. Brown-spotted bananas contain up to 80% more natural sugar than yellow ones. Two heavily spotted bananas will do far more for this cake than four barely-ripe ones. When in doubt, wait another day.

Everything at room temperature — and mean it. Cold eggs hitting warm creamed butter will cause the batter to separate. Set your butter and eggs out at least one hour before you start. If you forgot, run the eggs under warm tap water for 60 seconds.

325°F (165°C) is not negotiable. This is what builds the caramelized crust while keeping the interior moist. If your oven runs hot, use an oven thermometer and adjust. Baking at 350°F browns the outside before the inside sets.

Don’t open the oven door before 60 minutes. With no baking powder doing structural work, the batter is fragile in the first half of the bake. A cold draft can sink the center. Set a timer and walk away.

Let it cool completely before slicing. “The banana bread is not done baking when it comes out of the oven — it finishes as it cools.” Give it the full hour. Slice it warm and the crumb pulls apart. Slice it cooled and it’s clean, dense, and exactly what it should be.

Flour the pan, never sugar it. We use the same flour-based prep for our Southern banana nut cake — clean release, golden crust, every time. Sugar melts and welds the cake to the pan during a long bake like this one.

Banana Pound Cake Variations

This pound cake is beautiful as written — but it also adapts well. Here are the variations worth knowing about, from simple swaps to entirely different recipes.

Banana Walnut Pound Cake

The recipe as written is already a banana walnut pound cake when you include the walnuts. Toast them before folding in — 8 minutes at 350°F (175°C) — and use roughly chopped pieces rather than finely ground, so you get a real bite in each slice. A generous half cup is the sweet spot; more than that and the walnuts compete with the crumb structure.

Banana Nut Pound Cake with Pecans

Pecans are the more traditional Southern choice. Swap the walnuts for the same quantity of roughly chopped toasted pecans. They’re slightly sweeter and more buttery than walnuts, with a softer bite that disappears more naturally into the dense crumb. For a dedicated banana nut pound cake experience with a completely different flavor profile, our moist Southern banana nut cake is made in a sheet pan with a warm brown butter glaze — worth bookmarking.

With a Simple Vanilla Glaze

This cake traditionally needs nothing. But if you want a glaze: whisk together 1 cup powdered sugar, 2 tablespoons milk, and ½ teaspoon pure vanilla extract until smooth. Pour over the completely cooled cake and let it set for 10 minutes before slicing. Keep it thin — a heavy glaze would compete with the crust.

Lighter Bundt Version

If you want the bundt shape with a spongier, more classic cake texture and a pretty vanilla glaze poured over the top, this banana bundt cake version is what you’re looking for. It uses baking powder, only 2 eggs, and produces a completely different result — lighter, more open crumb, sweeter glaze. Same pan, different cake.

Banana Pudding Pound Cake

One of the most-searched variations in this cluster is banana pudding pound cake — a Southern dessert that layers sliced pound cake with banana pudding cream and whipped topping. The classic version uses store-bought pound cake, but homemade is richer and more satisfying. Slice this pound cake into cubes, layer it in a trifle dish with homemade banana pudding and whipped cream, and you have a showstopper dessert. For the full standalone recipe, our banana pudding from scratch makes the perfect base.

How to Store Banana Pound Cake

One of the best things about this recipe is how well it keeps. The high butter and egg content means the crumb stays moist and velvety for several days — and the flavor genuinely deepens after the first 24 hours.

Counter: 3 days — wrap tightly in plastic wrap or store in an airtight container at room temperature. The caramelized crust softens slightly by day 2, but the crumb stays dense and moist. The banana flavor is noticeably stronger the next day.

Fridge: Up to 5 days in an airtight container. Bring slices to room temperature for 20 minutes before serving, or warm in the microwave for 10 to 12 seconds.

Freezer: Up to 3 months. Slice the cake first, wrap each slice individually in plastic wrap, then place in a freezer-safe zip bag. Thaw slices at room temperature for 1 hour, or overnight in the fridge.

Meal prep tip: Bake this cake the night before you need it. It slices more cleanly once completely cooled and settled, and the banana flavor is noticeably richer on day 2. For another make-ahead banana bake that stays fresh all week, a classic banana bread loaf follows the same principle with far simpler ingredients.

Bake It Once, and It’s Yours Forever

You don’t need to be an expert baker to pull this off. You need ripe bananas, butter you remembered to set out, and the patience to let the mixer run a little longer than feels necessary. That’s it. The pound cake takes care of the rest.
