Old Fashioned 7UP Cake Recipe (The One Your Grandma Made)

This Old Fashioned 7UP Cake recipe has been in many Southern kitchens since 1953, when the 7UP company first published it in a promotional recipe booklet. It caught on fast, and decades later, it’s still one of those cakes people ask for by name at potlucks, holidays, and Sunday dinners. I made this cake with real 7UP, and it’s a fun perk of this job: the 7UP company sent me the soda I used to make it.

The recipe itself is the same one that’s been passed down in kitchens for over 70 years: butter, sugar, eggs, flour, lemon extract, and that signature fizz baked right into a jumbo Bundt cake. The carbonation does some of the work for you, giving the crumb a light, tender texture without a bunch of extra leavening. Below is my full 7UP Cake Recipe, with exact measurements and step-by-step directions so it turns out right the first time. 

Quick Facts

• Prep Time: 15 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 45 minutes
• Servings: 6-8
• Category: Dessert
• Cuisine: Southern, American
• Pan: Jumbo ring cake pan (bundt)
• Key Ingredient: 7UP soda

What Each Ingredient Does

• Butter — This is your fat and flavor base. 
• Sugar — Sweetens the cake and helps create that classic golden, slightly crisp crust on the outside.
• Eggs — Five eggs is a lot, and that’s the point. They give this cake its dense, rich, pound-cake texture and help everything bind together.
• Flour — The structure of the cake. Three cups gives you that sturdy, sliceable crumb you want in a bundt-style cake.
• Lemon Extract — This is where the citrus flavor comes from. It’s stronger and more concentrated than fresh lemon, so a little goes a long way.
• 7UP — The most important ingredient. The carbonation helps lighten the batter and gives the cake a little extra lift, while the lemon-lime flavor adds a subtle citrus note you can’t get any other way.
• Powdered Sugar (Glaze) — Creates that smooth, sweet glaze base. It dissolves easily and won’t add any graininess.
• Vanilla (Glaze) — Rounds out the glaze and keeps it from tasting one-note sweet.
• Lemon Juice (Glaze) — Adds brightness and a little tang to balance the sweetness of the powdered sugar.
• 7UP (Glaze) — Ties the glaze back to the cake with that same signature lemon-lime flavor, and thins the glaze to the right pourable consistency.

Tips for Success

• Use room temperature butter and eggs. Cold ingredients don’t cream together as well, and you’ll end up with a denser cake instead of that light, tender crumb you’re going for.
• Don’t skip the “scrape down the sides” step. It’s easy to rush past this, but it helps everything mix evenly so you don’t end up with pockets of flour or sugar in the finished cake.
• Grease your pan generously. A 15-cup Bundt pan has a lot of nooks and crannies, and this cake is dense enough that it can stick if you’re stingy with the butter or spray. Get into every groove.
• Check doneness with a toothpick, not just the timer. Ovens vary, so start checking around the 1-hour mark. If the toothpick comes out clean, it’s done, even if that’s before your full bake time is up.
• Let the cake cool for the full 10 minutes before flipping it out. Flip it too soon, and it can fall apart. Wait too long, and it can stick to the pan. Ten minutes is the sweet spot.
• Pour the glaze while the cake is still slightly warm. It soaks in better and gives you that glossy, slightly soaked-in finish instead of just sitting on top like frosting.

Why You’ll Love 7UP Cake

• It’s a true blast from the past. This isn’t a trendy new recipe. It’s the same 7UP Cake that’s been showing up at potlucks and Sunday dinners since 1953, and it still holds up.
• The texture is unbeatable. Thanks to the carbonation in the 7UP, this cake comes out light and tender instead of heavy, even with a full pound of butter and five eggs in the batter.
• It’s easier than it looks. No mixer skills required beyond basic creaming and mixing. If you can run a hand mixer, you can make this cake.
• The glaze makes it foolproof. Even if your cake bakes up a little uneven, the lemon glaze soaks in and covers any imperfections while adding extra flavor.
• It feeds a crowd. This cake serves 6-8 people, which makes it a solid choice for potlucks, holidays, or any time you need a dessert that’ll disappear fast.

Substitutions and Variations

• No 7UP on hand? Sprite or Sierra Mist work as a near-identical swap since they’re both lemon-lime sodas with similar carbonation. For a less sweet version, try club soda mixed with a splash of lemon juice.
• Want a stronger lemon flavor? Add a tablespoon of fresh lemon zest to the batter along with the lemon extract. It won’t change the texture, just boosts the citrus punch.
• Want to switch up the flavor? Swap the lemon extract for lime or orange extract, and use a matching soda (like a grapefruit or orange soda) for a completely different citrus profile using the same base recipe.
• Cutting back on sugar? You can reduce the glaze’s powdered sugar slightly without affecting the cake’s structure, since the glaze is purely for flavor and finish, not for holding the cake together.
• Adding texture? Fold in a cup of sweetened shredded coconut or finely chopped pecans right before pouring the batter into the pan for extra crunch and flavor.

Storage Tips

Room Temperature: Store the cake covered, either under a cake dome or wrapped tightly in plastic wrap, for up to 3-4 days. The glaze helps seal in moisture, so it stays fresh longer than an unglazed cake.

Refrigerator: If you want it to last longer, store it in an airtight container in the fridge for up to a week. Let slices come to room temperature before serving for the best texture, since cold butter cake can taste dense straight from the fridge.

Freezer: This cake freezes well for up to 3 months. Wrap it tightly in plastic wrap, then foil, to prevent freezer burn. Go ahead and glaze it before freezing, then thaw in the fridge overnight before serving. 

Thawing: Move the wrapped cake to the fridge overnight, then let it sit at room temperature for about an hour before serving.

Frequently Asked Questions

Why does my cake need so many eggs? Five eggs give this cake its dense, rich, pound-cake texture. Cutting back on eggs will change the structure and make the cake lighter and less sturdy.

Why did my cake sink in the middle? This usually means the cake needed a few more minutes in the oven, or the oven temperature ran cool. Always check with a toothpick starting at the 1-hour mark instead of relying on the timer alone.

Can I make the glaze ahead of time? Yes. Store it in an airtight container at room temperature for a few hours, or in the fridge overnight. Give it a quick stir before using since it can separate slightly as it sits.

Does the carbonation in 7UP bake out? The carbonation does cook off during baking, but it helps lighten the batter as it mixes and bakes.

How do I know when the cake is fully cooled before glazing? The pan should feel just warm to the touch, not hot. Glazing while it’s warm helps it soak in, but glazing while it’s too hot can cause the glaze to run off completely.

What to Serve with 7Up Cake

• Fresh Berries — A simple bowl of strawberries, blueberries, or raspberries cuts through the sweetness of the glaze and adds a fresh, juicy contrast.
• A Scoop of Vanilla Ice Cream — Classic, easy, and it turns a slice of this cake into a full dessert. If you want to make it from scratch, my no-churn custard ice cream recipe pairs perfectly with the citrus flavor here.
• Sweet Tea or Lemonade — This cake is Southern through and through, so a tall glass of sweet tea or my homemade lemonade fits right in alongside it. 
• Coffee — A simple cup of black coffee balances out the sweetness and makes this a great after-dinner or brunch option.
• Whipped Cream — A dollop on top adds a little extra richness without overpowering the lemon-lime flavor already in the cake.
• Other Retro Desserts for a Dessert Table — If you’re serving this cake at a potluck or holiday spread, it pairs well with other nostalgic favorites like my Wacky Cake or Mock Apple Pie for a full retro dessert lineup.
• Grilled or Fried Chicken — If you’re serving this as part of a full Southern meal rather than a standalone dessert, it’s a natural follow-up to a savory main like my grilled BBQ chicken.
