This Easy Lemonade Cake Recipe with Cream Cheese Frosting is the kind of sheet cake that tastes better after a little time in the fridge. The crumb drinks in a tart lemonade soak, so every forkful is cold, soft, and bright.
I like it for cookouts, birthdays, and any day when a layer cake feels like too much work. You bake one 9x13 pan, poke it while warm, pour over the lemonade mixture, then frost it once the cake has cooled.
Bright Cake Pantry Lineup
The shortcut is a good lemon cake mix, but the flavor comes from frozen lemonade concentrate. Let the concentrate thaw fully so it blends into both the soak and frosting without icy pockets.
- Lemon cake mix. Gives the cake a dependable soft crumb and a head start on lemon flavor.
- Eggs. Help the sheet cake rise and slice cleanly after chilling.
- Vegetable oil. Keeps the crumb moist even after refrigeration.
- Water. Loosens the batter so it bakes evenly in a 9x13 pan.
- Frozen lemonade concentrate. Adds the sweet-tart punch in the soak and frosting.
- Powdered sugar. Sweetens the soak and makes the frosting smooth.
- Cream cheese. Gives the frosting tang and a thick, creamy body.
- Butter. Softens the cream cheese edge and helps the frosting spread.
- Lemon zest. Adds fresh citrus aroma without making the cake sour.
- Vanilla and salt. Round out the frosting so it tastes creamy, not flat.
Bake Soak Frost Chill
- Prepare the pan. Heat the oven to 350°F and grease a 9x13-inch baking pan so the chilled slices lift out neatly.
- Mix the batter. Beat the cake mix with eggs, oil, water, and lemon zest until smooth, then spread it evenly in the pan.
- Bake the cake. Bake for 28-33 minutes, until the center springs back and a toothpick comes out with a few moist crumbs.
- Poke and soak. Cool for 10-15 minutes, poke small holes across the top, then slowly pour over the lemonade and powdered sugar mixture.
- Chill the cake. Let the cake cool to room temperature, then refrigerate until cold so the crumb firms up before frosting.
- Make the frosting. Beat cream cheese and butter until smooth, then add powdered sugar, lemonade concentrate, vanilla, and salt.
- Frost and serve. Spread the frosting over the cold cake, garnish with zest or lemon slices, and chill again before slicing.
Easy Lemonade Cake Recipe Notes
The lemonade soak is what makes this cake feel different from a plain lemon sheet cake. Mix the concentrate with powdered sugar until it looks glossy, then pour it slowly over the warm cake. I adapted the method after comparing classic poke-style lemonade cakes, including this I Wash You Dry version, and the small pause before soaking matters. If the cake is screaming hot, the syrup can sink too aggressively and leave wet spots. If it is completely cold, the soak mostly sits on top.
Use a fork, skewer, or chopstick for the holes. Keep them close but not huge. You want little channels, not craters. For a similar easy lemon dessert already on the site, try Super Easy Lemonade Cake.
Frosting That Stays Creamy
Cold cream cheese is the usual reason for lumpy frosting. Set the cream cheese and butter out until they are soft enough to press with a finger, but not shiny or melted. Beat them together first, before any sugar goes in. Once that base is smooth, add the powdered sugar in stages. The lemonade concentrate goes in near the end, and just a few tablespoons are enough.
If the frosting feels loose, beat in another half cup of powdered sugar. If it tastes too sweet, add a small pinch of salt and a little more lemon zest. The same cream cheese balance works well in richer desserts like Butter Pecan Cake Loaf Recipe with Cream Cheese Icing and Old-Fashioned Pumpkin Bars Cream Cheese.
Swaps Worth Making
A vanilla cake mix works if you want a softer lemon flavor. Add extra zest to the batter so the cake still smells fresh. Yellow cake mix also works, though the final color will be warmer and less bright. Pink lemonade concentrate can be used for a rosy version, especially if you garnish with strawberries.
Do not replace the frozen concentrate with dry lemonade powder one for one. The powder is much sweeter and can make the frosting gritty. If that is all you have, dissolve a small amount in warm water first, then add it slowly and taste as you go. For a larger citrus dessert, the Strawberry Lemonade Layer Cake is a good next bake.
Serving It Cold
This cake is at its best straight from the fridge. The chill tightens the crumb, sets the frosting, and makes the lemonade flavor taste cleaner. For neat squares, wipe the knife between cuts. If you are taking it to a party, keep it in the pan and cover it loosely so the frosting does not stick.
Because this recipe uses cream cheese frosting, store leftovers covered in the refrigerator. The USDA advises refrigerating perishable leftovers promptly, and their leftovers safety guide is a useful reference. I like the texture best within 3 days, though it keeps up to 4 days if well covered.

FAQs
- Can I use fresh lemon juice instead of lemonade concentrate?
Fresh lemon juice is sharper and thinner than frozen lemonade concentrate, so it will not give the same sweet-tart soak. If you only have fresh lemons, use bottled lemonade or make a quick syrup with lemon juice and sugar first.
- Does lemonade cake with cream cheese frosting need refrigeration?
Yes. The frosting contains cream cheese, and this cake also tastes best chilled. Cover the pan and keep it in the refrigerator until serving.
- Can I make this cake ahead of time?
Yes. Bake and soak the cake up to 2 days ahead, then frost it once it is cold. You can also frost it a full day ahead, which gives the lemon flavor time to settle into the crumb.
- Can I make it as a layer cake?
You can bake the batter in two 8-inch or 9-inch round pans, but use less soak so the layers do not get soggy. Brush the lemonade mixture on gradually and stop when the cake looks moist, not wet.
- Why did my lemonade cake turn mushy?
The cake was probably too hot or the soak was poured in too quickly. Let it cool for 10-15 minutes, poke small holes all over, then pour slowly so the syrup can spread instead of pooling.
- What can I serve with lemonade cake?
Fresh berries are the easiest pairing. Strawberries, blueberries, raspberries, and a few mint leaves make the chilled lemon flavor taste even brighter without adding more sweetness.
