4 Ingredient Air Fryer Pound Cake (No Baking Powder)

Flour, sugar, butter, eggs. That’s the whole list. No baking powder, no vanilla, no milk — this is the original pound cake, the one that got its name because you use a pound of each of the four ingredients. And it bakes beautifully in the air fryer in about 20 minutes.

I make this the night before when I know the morning is going to get away from me. A slice of buttery pound cake with coffee, and the day starts a lot better than it would have otherwise.

Why This Pound Cake Only Needs 4 Ingredients

The name is literal. An old-fashioned pound cake called for one pound of butter, one pound of sugar, one pound of flour, and one pound of eggs — no leavening, no flavorings, nothing else. Bakers memorized it because there was nothing to memorize.

That equal-weight ratio is doing all the work. Creaming a pound of butter with a pound of sugar whips a huge amount of air into the batter, and nine eggs bring enough protein and moisture to set that structure as it bakes. You don’t need baking powder because the creaming step is the leavening.

This surprises people every time: yes, nine eggs. A pound of large eggs, out of the shell, is right around nine of them.

If you’d rather have a version with vanilla and salt in it, I’ve got that one too — my Air Fryer Easy Pound Cake is the same idea with a little more flavor built in.

Ingredients

• Large eggs: Room temperature. Cold eggs will seize the creamed butter and give you a curdled-looking batter.
• Granulated sugar: Creams with the butter to create the lift.
• Unsalted butter: This is the flavor and the tenderness. It needs to be soft enough to dent with a finger, but not melty.
• All-purpose flour: Measure by spooning into the cup and leveling off. Scooping packs in too much flour and gives you a dry cake.

Baking by weight? For a true pound-for-pound cake, use 1 pound (454 g) each of butter, sugar, flour, and shelled eggs. That’s a touch more sugar than the cup measurement above and gives you a slightly sweeter, more tender crumb.

Why There’s No Baking Powder in Pound Cake

This is the question I get most, so let me answer it properly: a traditional pound cake is leavened entirely by air and steam.

When you beat softened butter with sugar for several minutes, the sharp sugar crystals cut thousands of tiny air pockets into the fat. Those pockets expand in the heat of the air fryer, and the water in the butter and eggs turns to steam and pushes them further. That’s your rise.

Adding baking powder to a pound cake doesn’t make it better — it makes it fluffy and open, which is exactly what a pound cake isn’t supposed to be. You want that dense, close, buttery crumb that holds up under a scoop of ice cream.

The takeaway: don’t rush the creaming. Give it a full 4 to 5 minutes with a stand or hand mixer until the mixture is pale and noticeably lighter. Skimp on this step and you’ll get a heavy cake, and there’s no baking powder to bail you out.

Can I Use Self-Rising Flour?

Use all-purpose flour for this recipe. Self-rising flour already contains baking powder and salt, which will give you a lighter, more open crumb — closer to a yellow cake than a pound cake.

Cake flour works if you want an even more tender result. Whole wheat and gluten-free blends both work as a 1:1 swap, but expect a denser crumb and a longer bake time — one reader baking gluten-free found it took closer to an hour.

What Size Pan Should I Use in the Air Fryer?

Mini loaf pans, 5 3/4 x 3 inches. This is the single most important thing I can tell you about baking quick breads in an air fryer.

This recipe fills three of them. A full-size 9×5 loaf pan is too deep for circulating air to handle — the outside sets and browns long before the center is done, and you end up with a raw stripe down the middle. Mini loaves cook through evenly because there’s simply less distance to the center.

Leave at least an inch of space around the pan in the basket so air can move. If your air fryer is small, bake one loaf at a time rather than crowding them.

I keep a set of four mini loaf pans on hand and they get used constantly — they’re the same ones I use for air fryer banana bread and air fryer apple cranberry bread.

How to Make Air Fryer Pound Cake

Step 1: Cream the butter and sugar. In a large bowl, beat the room-temperature butter and sugar on medium-high for 4 to 5 minutes, until pale and fluffy. Scrape the bowl down halfway through. Don’t shortcut this.

Step 2: Add the eggs one at a time. Beat in each egg fully before adding the next. If the batter starts to look separated, add a spoonful of your flour to bring it back together.

Step 3: Fold in the flour. Add the flour in three additions on low speed, mixing only until the last streaks disappear. Overmixing here builds gluten and toughens the cake.

Step 4: Fill the pans. Grease three mini loaf pans well and fill each about two-thirds full. Smooth the tops. Air fry at 320°F for 20 minutes. Use the air fry setting. Don’t go hotter — pound cake is dense and a high temperature will brown the top before the center cooks.

step 5: Check and continue. Insert a toothpick into the center. Moist crumbs mean it’s done; wet batter means it needs more time. Add 5 minutes and check again, repeating until it’s set. Cool in the pan for 10 minutes, then turn out onto a rack to cool completely before slicing.

How Long Does Pound Cake Take in an Air Fryer?

20 to 30 minutes in mini loaf pans at 320°F. But every air fryer runs a little differently — yours might finish in 20 minutes where your neighbor’s takes 28.

Don’t bake by the clock. Bake to the toothpick. A clean toothpick or one with a few moist crumbs clinging to it means you’re done; wet batter means keep going in 5-minute increments.

In a regular 9×5 loaf pan, expect closer to 50 to 60 minutes, and tent the top loosely with foil once it’s golden so it doesn’t over-brown while the center finishes. It’s doable, but mini loaves genuinely give you a better cake.

Can I Make Less Than Three Loaves?

Yes. The classic ratio makes a lot of cake, so divide everything by three for a single mini loaf: 3 eggs, 2/3 cup sugar, 2/3 cup butter, and a scant 1 1/4 cups flour. Bake at the same temperature and start checking at 20 minutes.

How to Store Pound Cake

Room temperature: Wrap tightly in plastic wrap and keep on the counter for 2 to 3 days. Pound cake is high in fat, which keeps it moist longer than most cakes.

Refrigerator: Beyond 3 days, move it to the fridge in an airtight container for up to a week. Let slices come back to room temperature before serving — cold butter tastes flat.

Freezer: Cool completely, wrap in plastic wrap, then wrap again in foil, and seal in a freezer bag. It keeps for 2 to 3 months. Thaw on the counter or overnight in the refrigerator, still wrapped, so condensation forms on the foil instead of the cake.

Ways to Change It Up

Once you’ve made the plain version, this batter takes add-ins easily. Fold in up to a cup of chocolate chips, fresh berries, or chopped pecans or walnuts right at the end — toss fruit in a spoonful of flour first so it doesn’t sink.

If you’d rather start from a recipe that’s already built around the flavor, I’ve worked out a few in the air fryer: a double chocolate pound cake, a swirled marble pound cake, a blueberry pound cake, a cinnamon walnut version, and a banana walnut pound cake for overripe bananas. For something richer and tangier, my Southern sour cream pound cake is the one I make for company.

Frequently Asked Questions

Do I really need nine eggs? For the full three-loaf batch, yes — a pound of eggs is about nine large ones. Divide the recipe by three if that’s more cake than you need.

Why is my pound cake dense and heavy? Almost always under-creamed butter and sugar, or cold ingredients. Beat for a full 4 to 5 minutes until visibly pale, and make sure your butter and eggs are at room temperature.

Why did my cake sink in the middle? It came out before the center set. There’s no chemical leavening holding this cake up, so an underbaked middle collapses as it cools. Test with a toothpick in the very center, not near the edge.

Can I add vanilla? Absolutely — a tablespoon of vanilla extract and a teaspoon of salt turn this into my Air Fryer Easy Pound Cake. It’s no longer a strict 4-ingredient cake, but it’s delicious.

Do I need to preheat the air fryer? I don’t for this recipe, since the bake time is long enough to even out. If your air fryer runs cool, preheat for 3 minutes and start checking at 18 minutes.

Can I use a bundt pan? Only if it fits with an inch of clearance around it. A 6-inch bundt pan works in larger baskets and takes about 35 to 40 minutes.
