Laced with zippy lemon and juicy berries, the cake bakes up tender and moist in a simple sheet pan, making it ideal for sharing.

Every time I bake this for friends it disappears in minutes since both adults and kids gobble it up. The fresh lemon aroma alone brings everyone running into the kitchen.
Ingredients
- All-purpose flour: Provides structure for a cake that stays fluffy. Never substitute with cake flour which can lead to a texture that is too light for juicy berries.
- Granulated sugar: Brings the right level of sweetness and helps the cake caramelize at the edges. Use a fine white sugar for best mixing.
- Unsalted butter: Adds rich flavor and tenderness. Let it soften at room temperature so it creams smoothly with the sugar.
- Buttermilk: Keeps the cake moist and gives it a tender crumb. Always shake buttermilk well before using and use full-fat if you can find it.
- Large eggs: Help bind the batter and add richness. Choose fresh eggs for best rise and color.
- Lemon zest and juice: Infuse the cake with bright tang. Look for unwaxed lemons with glossy skin and grate only the yellow part to avoid bitterness.
- Baking powder and baking soda: Provide lift. Make sure both are fresh so your cake rises properly.
- Salt: Balances flavors and wakes up the berries.
- Mixed berries: Add color and sweet tart pops in every bite. Choose a mix of ripe blueberries, raspberries, and chopped strawberries, and pat them dry before folding in so the batter does not thin out.
- Powdered sugar: Forms the base for the lemon glaze. Sift before mixing for a smooth finish.
- Fresh lemon juice: Gives the glaze its signature zing.
- Milk: Allows you to adjust the glaze to your preferred consistency. Use whole or two percent for a creamy glaze.
- Fresh mint leaves (optional): Give a burst of color and freshness when garnishing. Look for bright green tender sprigs.
- Extra mixed berries (optional): For pretty presentation and more fruity flavor.
Step-by-Step Instructions
- Preheat the Oven:
- Get your oven ready at three hundred fifty degrees Fahrenheit or one hundred seventy five Celsius so the cake begins baking right away. Place your rack in the middle of the oven for even heat.
- Prepare the Cake Batter:
- Begin by creaming the softened butter and granulated sugar in a large mixing bowl. Mix on medium speed for about three to four minutes until the mixture turns pale and fluffy. Scrape down the sides to make sure everything is incorporated. Add the eggs one by one, mixing well after each egg. Then stir in the lemon zest and fresh lemon juice until completely combined. Your batter should now smell wonderfully fragrant.
- Combine Dry Ingredients:
- Whisk together the flour, baking powder, baking soda, and salt in a separate bowl. Whisk thoroughly so there are no clumps. This ensures even distribution throughout the batter, which means every bite gets the right rise.
- Combine Wet and Dry Ingredients:
- Gradually add the dry mixture to the buttery wet ingredients, alternating with the buttermilk. Start with a portion of dry, then a splash of buttermilk, and repeat, always ending with dry. Mix just until everything is incorporated. The batter should be thick but smooth. Over mixing can make the cake tough, so stop once no dry flour remains.
- Fold in Berries:
- Gently fold in the mixed berries using a spatula. Turn the batter over softly so the berries do not burst and bleed too much color. This keeps the cake attractive with bright berry pockets.
- Bake the Cake:
- Pour the finished batter into your greased or parchment-lined sheet pan and spread it out evenly to the corners. Use an offset spatula for a level surface. Place the pan in the preheated oven and bake for twenty five to thirty minutes. Check doneness by inserting a toothpick in the center. It should come out clean or with a few moist crumbs.
- Cool the Cake:
- Once baked, let the cake cool in the pan for about ten minutes so it settles and firms up. Transfer carefully to a wire rack using the parchment paper as a sling. Finish cooling completely before glazing to prevent melting the glaze.
- Prepare the Lemon Glaze:
- Whisk together the powdered sugar, lemon juice, and enough milk to reach a smooth, pourable consistency. You want it thick enough to coat the cake but fluid enough to drizzle from a spoon. Adjust with more milk or sugar as needed.
- Glaze the Cake:
- When the cake is cool, drizzle the glaze evenly over the surface. Spread gently with a spatula if you want full coverage. Let the glaze set for a shiny finish and a tangy sweet crust on top.
- Garnish and Serve:
- For a festive touch, scatter extra berries and mint leaves over the glazed cake. Cut into neat squares and serve right from the sheet pan. Each piece should have a mix of lemony sponge, juicy berries, and a glossy finish.

I always look forward to zesting the lemons because the scent fills my kitchen and makes even a rainy day feel sunny. My kids love picking out their favorite berry to tuck into the batter and are so proud to help decorate before serving.
Storage Tips
This lemon berry cake keeps beautifully at room temperature for up to two days as long as it is kept covered with foil or in an airtight container. If you need it to hold longer, refrigerate for up to five days. Bring slices to room temperature before serving for the best texture. The glaze helps lock in moisture so the cake never gets dry.
Ingredient Substitutions
If you are out of buttermilk, make your own by adding a tablespoon of lemon juice to regular milk and letting it sit for five minutes. For berries, you can use frozen mixed berries. Just thaw them first and pat dry to avoid adding extra moisture. No lemons? Use limes for a twist or even a mix of citrus like Meyer lemons and oranges.
Serving Suggestions
This cake is perfect as is or paired with a scoop of vanilla ice cream for extra decadence. It is also great with whipped cream and extra fresh berries. Stack slices with strawberry jam for a unique layered treat. For brunch, spread with lemon curd for a brunch buffet highlight.
