If you have ever wanted a pound cake that tastes like it put on a clean white tee and walked out into sunshine, this is your cake. 7UP cake is old-school in the best way: rich and buttery, but with this little lemon-lime sparkle that keeps each bite from feeling heavy.

The magic is not that the soda makes it taste like a soft drink. It is more that 7UP brings extra moisture, sweetness, and a little acidity that plays nicely with the batter and helps the texture stay tender. The bubbles do not really survive the bake, but the cake sure does. Then the glaze made with 7UP soaks in just enough to give you that glossy, sweet-tart finish. It is the kind of cake you slice “just to taste” and somehow you are back in the kitchen cutting another “tiny” piece five minutes later.

Ingredients for 7UP cake arranged on a kitchen counter including flour, sugar, butter, eggs, 7UP, lemons, and a bundt pan

Why It Works

  • Bright flavor without extra fuss: lemon zest and a little 7UP bring a clean citrus lift.
  • Classic pound cake texture: tight, velvety crumb with crisp edges when baked in a bundt pan.
  • Glaze that actually matters: a thick 7UP glaze sets into a shiny top and keeps slices tasting good the next day.
  • No weird ingredients: everything is grocery-store easy, and the steps are straightforward.

Storage Tips

Room temperature: Store covered (cake dome or tightly wrapped) for up to 3 days. Pound cake loves a snug wrap.

Refrigerator: Refrigerate up to 6 days if you need the extra time, but wrap it well. The fridge can firm up and dry cakes a bit, so let slices come to room temperature before eating for the best texture.

Freezer: Freeze unglazed or glazed. Wrap the whole cake or individual slices in plastic wrap, then foil. Freeze up to 2 months. Thaw overnight in the fridge or a few hours at room temperature, still wrapped.

Best leftover move: Toast a slice in a dry skillet for 1 to 2 minutes per side. Crisp edge, soft middle. Dangerous.

Common Questions

Does 7UP cake need baking powder or baking soda?

Traditionally, this style of 7UP pound cake relies on eggs + proper creaming for lift and uses self-rising flour (which already contains leavening and salt). This recipe follows that classic approach. If you only have all-purpose flour, see the next question.

Can I use all-purpose flour instead of self-rising?

Yes. A standard swap is: for every 1 cup self-rising flour, use 1 cup all-purpose flour + 1 1/2 teaspoons baking powder + 1/4 teaspoon fine salt. For this recipe, that comes out to 3 cups all-purpose flour + 4 1/2 teaspoons baking powder + 3/4 teaspoon fine salt. Whisk it together really well before adding. (Baking powder brands can vary a bit, so treat this as a solid baseline.)

Can I use Sprite or Sierra Mist instead of 7UP?

Absolutely. Any lemon-lime soda works. Use the regular (not diet) version for the classic texture and sweetness.

Why did my pound cake crack on top?

That crack is normal and honestly kind of iconic. It usually means the oven is hot enough to set the outside while the inside keeps rising. If it feels excessive, your oven may run a little hot. Use an oven thermometer and consider dropping the temp by 10 to 15 degrees Fahrenheit.

How do I keep a bundt cake from sticking?

Grease every curve like you mean it. I use softened butter or baking spray with flour, then dust lightly with flour and tap out the excess. Let the cake cool 10 to 15 minutes, then invert. Too soon and it can tear, too late and it can glue itself in.

Can I make this in loaf pans?

Yes. Divide batter between two 9x5-inch loaf pans. Start checking around 55 to 65 minutes. You want a tester to come out clean or with a few moist crumbs.

I love recipes like this because they feel like a handshake from someone who has been feeding people for a long time. 7UP cake is not trying to be trendy. It is just a solid, buttery pound cake with a little citrus attitude. The first time I made it, I was convinced the soda was going to be a gimmick. Then I cut into it and got that tight, tender crumb and the crisp edge from the bundt pan, and I was fully converted. Now it is my “bring something sweet” default, because it slices clean, travels well, and everyone mysteriously asks for the recipe like it is top secret.
