Tart and Sweet Strawberry Lemonade Cake
This strawberry lemonade cake tastes exactly like summer. Fresh strawberries, sharp lemon zest, and a buttermilk crumb come together in a simple sheet cake that stays moist for days.
It is the sort of cake you pull out when you need something bright and cheerful that does not demand a ton of fuss.
Why This Strawberry Lemonade Cake Works
I keep coming back to this one because the crumb is tender but sturdy enough to hold all the juicy berries. The fresh lemon zest and tangy glaze cut through the sweetness so the cake never tastes flat or cloying.
Sour cream or buttermilk in the batter gives it a soft, velvety texture that stays moist even after a night in the fridge, which makes it a great make-ahead choice.
Ingredients
- 2 cups (250 g) all-purpose flour: spooned and leveled, not scooped
- 2 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- ¾ cup (170 g) unsalted butter, softened: let it sit at room temperature for 30 minutes
- 1 cup (200 g) granulated sugar
- 2 large eggs, room temperature
- 2 tbsp fresh lemon zest: from about 2 medium lemons
- 1 tsp vanilla extract
- ¾ cup (180 ml) buttermilk, room temperature: or whole milk with 2 tsp lemon juice stirred in
- 1½ cups diced fresh strawberries: cut into small, even pieces, not mashed
- 1 tsp all-purpose flour: for tossing the berries
For the glaze:
- 1 cup (120 g) powdered sugar
- 2 to 3 tbsp fresh lemon juice
- Pinch of salt
Variations and Substitutions
- Frozen strawberries: Pat them dry and do not thaw before folding them in. The cake will need an extra 5 to 8 minutes in the oven.
- Blueberries or raspberries: Either works in the same quantity. Raspberries break down a bit more, so fold them in last with extra care.
- Lime instead of lemon: Swap zest and juice for a limeade twist that plays just as well with the berries.
- Dairy-free: Use a neutral oil in place of butter and a plant-based yogurt thinned with a little oat milk for the buttermilk. The crumb will be a shade more dense.

How to Make Strawberry Lemonade Cake
Step 1: Mix the Dry Ingredients
Heat your oven to 350°F (175°C) and grease a 9×13-inch metal baking pan. Whisk together the 2 cups of flour, baking powder, baking soda, and salt in a medium bowl.
This step wakes up the leavening and distributes the salt so you do not end up with dry pockets later. The mixture should look evenly blended with no streaks of baking powder.
Step 2: Cream the Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar with an electric mixer on medium speed until pale and fluffy, about 3 minutes. Add the eggs one at a time, mixing well after each, then beat in the lemon zest and vanilla.
The mixture will look thick and creamy, and the lemon zest will speckle it all through. Scrape down the sides of the bowl once to catch any butter that clings.
Step 3: Fold in the Strawberries
Add half the flour mixture to the butter mixture and mix on low just until it disappears. Pour in the buttermilk and mix gently, then add the rest of the flour. Stop the moment the last streak of flour vanishes. Toss the diced strawberries with the 1 teaspoon of flour, then fold them into the batter by hand with a flexible spatula.
The batter will be thick and dotted with pink. Overmixing now will make the cake tough, so a few gentle turns are all you need.
Step 4: Bake the Cake
Scrape the batter into the prepared pan and spread it into an even layer. Bake on the middle rack for 30 to 35 minutes, until the top is golden and a toothpick inserted in the center comes out with just a few moist crumbs.
The edges will pull away from the sides of the pan slightly, and the kitchen will smell like warm lemon and sweet berry. Do not open the oven door before the 28-minute mark or the cake may sink in the middle.
Step 5: Glaze and Serve
Let the cake cool in the pan on a wire rack for 10 minutes. Whisk the powdered sugar with 2 tablespoons of lemon juice and a pinch of salt, adding more juice a teaspoon at a time until the glaze is thick but pourable. Drizzle it over the warm cake, then let it set for at least 15 minutes before slicing.
The glaze will soak into the top of the cake and leave a shiny, crackly finish that catches every piece of strawberry peeking through.
A Few Notes for the Best Cake
- All your cold ingredients truly need to be at room temperature. Cold butter will not cream properly, and cold eggs can seize the batter.
- Toss the berries in a little flour before folding them in so they stay suspended in the crumb and do not all sink to the bottom.
- The glaze firms up fast on a warm cake, which gives you that pretty crackled look. If you want a softer, more soaked glaze, wait until the cake is completely cool before drizzling.
- To make real buttermilk in a pinch, stir 2 teaspoons of lemon juice or white vinegar into ¾ cup room-temperature whole milk and let it sit for 5 minutes.
Bake times by pan:
| Pan | Material | Time |
|---|---|---|
| 9×13-inch | Metal | 30 to 35 mins |
| 9×13-inch | Glass | 35 to 40 mins |
| Two 8-inch rounds | Metal | 25 to 28 mins |
Keeping the Cake Fresh
Cover the cake tightly and keep it in the refrigerator for up to 3 days. The crumb stays moist and the glaze holds its shine. Let slices come to room temperature before serving for the best flavor. This cake does not need reheating.
What to Serve with Strawberry Lemonade Cake
A spoonful of lightly sweetened whipped cream balances the tart glaze without covering up the berry flavor. A scoop of good vanilla ice cream on a warm slice makes the lemon pop even more. Fresh berries on the side add a juicy contrast to the tender crumb.
Frequently Asked Questions
Can I use frozen strawberries?
Yes. Keep them frozen, do not thaw, and toss them in the flour straight from the bag. The bake time will run closer to 40 minutes.
How do I make this cake gluten-free?
Swap the all-purpose flour for a 1-to-1 gluten-free baking blend that contains xanthan gum. The texture will be a little more crumbly, but the flavor stays bright.
Why did my cake sink in the middle?
The most common cause is opening the oven door too early. The center of a butter cake sets last, and a burst of cool air can collapse it before the crumb is strong enough to hold.
Can I use lemon extract instead of fresh zest?
You can, but the result will taste flatter. Fresh zest carries the lemon oils that give the cake its real punch, so I would not skip it unless you must.
