This pretty blueberry lemon cake is my absolute go-to recipe for birthdays and warm-weather gatherings because it’s completely from-scratch, surprisingly simple, and guaranteed to steal the show.

Blueberry lemon cake is perfect for spring!
My blueberry lemon layer cake is bursting with juicy berries and fresh citrus. It makes a wonderfully unique birthday cake, and I’ve yet to meet a soul who can resist it! Lemon paired with berries is a natural choice for spring and summer desserts because the flavors are so light and bright. There is a reason this fruity combo has a cult following ~ something special happens when the two get together.

Key ingredients for blueberry lemon cake (and why I use them)
CAKE FLOUR: it gives me a softer, lighter, more tender crumb. You can swap AP flour for a slightly firmer cake texture.
BUTTERMILK: also makes a softer crumb, a better rise, and brighter flavor. Look for cultured buttermilk right next to regular milk in your store, and be sure to shake the carton before using.
LEMON SUGAR: I make lemon sugar by processing granulated sugar with the zest of lemon, and the result is an aromatic, super lemony sugar that gives a vibrancy to cakes, and other baked goods like nothing else.

The secret to a vibrant lemon buttercream
I give the lemon and blueberries equal billing in this recipe; I’ve used almost an entire pint of berries in the cake batter, but that’s balanced by a super tangy lemon buttercream frosting to tie it all together. The secret to a vibrant lemon buttercream is plenty of lemon juice. I don’t use any milk or cream to dilute the flavor.
This is a ‘crusting’ frosting, which is a not-so-pretty way to describe an old fashioned American buttercream, made simply with butter and confectioner’s sugar. I like it because it needs no refrigeration so your blueberry lemon cake can live on the counter.

Sue’s tips for a light and fluffy crumb
You can see the lovely fluffy crumb in the photos…I’m a stickler for that texture in cakes. This blueberry lemon cake recipe gives you the light fluffy result of a boxed mix, with the flavor and character that only a homemade cake can give.
- Preheat your oven, this is important! The oven has to be at temperature when you slide your cake in or it won’t rise properly. I use an inexpensive oven thermometer to double check the temperature. Did you know that the majority of ovens do not run true to temperature?? That can spell disaster for baking.
- Prep your pans. Grease with butter, dust with flour, and line the bottom with a parchment circle. Do this before mixing so the batter can go straight into the oven.
- Follow the recipe. It sounds silly, but it makes a difference…baking is a complex chemical process and cake recipes are carefully composed. Changes are risky.
- Whip it good. A stand mixer or electric hand mixer is essential for creaming the butter and sugar. Don’t skimp on this step; beating in air is what guarantees a light cake.
- Your ingredients should be at room temperature, especially the butter and eggs. That helps them to emulsify together and create a smooth batter. See my guide to Quickly bring cold ingredients to room temperature for baking.
- No peeking! Don’t open the oven to check on your cakes during the first 2/3 of the baking time. If you need to check or rearrange your cake pans, do it quickly so you don’t lose precious oven heat.
- Don’t over bake. The cake is done when it springs back lightly when touched in the center, when it has just started pulling away from the sides of the pan, and when a toothpick inserted in the deepest part comes out without wet batter on it.

Ideas for decorating this blueberry layer cake
Of course you can leave it plain, but why?
- Blueberries ~ I arrange blueberries around the edge of the cake and garnish with thyme sprigs and a dusting of powdered sugar that accents the berries.
- Edible flowers ~ purple pansies or violas would be perfect.
- Thinly sliced lemon ~ decorate like I did but add very thin slices of lemon among the berries.

Tips for baking ahead and storage
- When I’m pressed for time I’ll make the cake layers ahead and frost it later that day, or even the next day.
- The finished cake is shelf stable
- 2–3 days at room temperature (covered)
- Keep it in a cool spot, out of sun/heat

Blueberry Lemon Cake
Equipment
- 2 9-inch round cake pans
- parchment paper rounds
- food processor to make the lemon sugar
Ingredients
- 3 cups cake flour, (you can also use regular flour)
- 1 Tbsp baking powder
- 1/2 tsp salt
- 1 3/4 cup granulated sugar
- zest of 1 lemon, peeled with a vegetable peeler (no white pith)
- 1 cup unsalted butter, at room temperature
- 3 jumbo or 4 large eggs, at room temperature
- 2 tsp lemon paste, optional
- 1 cup buttermilk
- 1/3 cup fresh lemon juice
- 1 pint blueberries
lemon buttercream
- 1 cup unsalted butter, at room temperature
- 6 cups confectioner's sugar
- 6-8 Tbsp fresh lemon juice
garnish
- blueberries
- thyme sprigs
- powdered sugar
Instructions
- Preheat oven to 350F Grease and flour two 9-inch round cake pans, putting a round of parchment paper at the bottom of each one.
- Whisk together the flour, baking powder and salt and set aside.
- Put the sugar and lemon zest into a food processor and process until moist, pale yellow, and no large pieces of zest remain. This will take under a minute.
- Cream the butter and sugar together in a stand mixer for 3 minutes, scraping down the sides of the machine as necessary.
- Beat in the eggs, one at a time, scraping down the sides of the bowl in between each addition. Beat in the lemon paste, if you’re using it.
- Turn the mixer to low and add the flour mixture, and just before it’s completely mixed in, add the buttermilk and lemon juice. Blend until combined, but don’t over-mix. I like to finish by hand to get everything incorporated.
- Gently fold in the blueberries. Note: I didn't use quite the whole pint. Then divide the batter equally between the two prepared pans. Spread out to an even layer.
- Bake the cakes in the center of the oven for about 35 minutes, or until just beginning to pull away from the sides of the pan, the top springs back when touched, and a toothpick comes out without any wet batter on it (moist crumbs are fine.)
- Let the cakes cool on a rack for 10 minutes, then remove them from the pans and continue to cool completely before frosting.
- To make the frosting, beat the soft butter and sugar together, gradually adding enough lemon juice to create a creamy spreadable frosting. If it is too thick, add more lemon juice, and if it is too thin, add a little more sifted sugar.
- Frost the cake and then decorate as you like. Store, covered, at room temperature.

Hello Miss Sue ?
Novice question here. When you decorate a cake, you have to put it in refrigerator for a few hours first to let the frosting set and then decorate ??
Because I decorated 5 min. after doing the frosting and the fruits(strawberries) melted(leaked) leaving red lines on top of cake.
Also, do you yourself have a recipes book ?
Do you know of an alternative for Buttermilk ?
Is there a way to avoid the publicity ?
Thank you so much for your blog, ?
I love your website and your recipes/tricks.

Hi Cynthia ~ as for the frosting, I used blueberries which are whole, so no chance of juice leakage. If you use cut strawberries that could be an issue, I would place them on the cake just before serving. I don’t have a cookbook out (yet!) An alternative for buttermilk might be milk mixed with a little lemon juice to sour it, or whole milk, half and half, or even cream. Hope this helps!
Thank you Miss Sue, for the tip and answering my question. Have a great week, stay safe.?
This was incredible! Made this cake for my mom’s retirement and it turned out perfectly. Only change I’ll make next time is a different frosting because it was just too sweet for me.
This was easy to make and absolutely delicious! Perfect cake for my mom’s birthday. Thank you for sharing !
I’ve made this a couple of times and it’s always a big hit! I’m about to make another one for my mother’s birthday tomorrow ?
The cakes turned out great but the frosting is yellow because of the butter, what can I do to make it white??? Doesn’t look pretty yellow…sad
Butter can vary a great deal in color, Irma! If you really want a whiter frosting try to source a very pale butter. Personally I love the lemony color that a yellow butter gives the frosting.
I want to try making this for 4th of July! But I’m just wondering did you use powder buttermilk or liquid buttermilk?
I always use liquid buttermilk.
Great recepy grate cake!! It came out light and fluffy I added a little lavander in the frosting and it came out delicious ? my kids loved it !
How much lavender did you add if you don’t mind me asking?
This cake looks delish! I’m so exited to try it.
Do you think this could work with two 8 inch pans instead? I’m sure the cooking time would have to increase with the height difference ?
Yes, you can definitely bake this in 8 inch cakes, just give it a few more minutes in the oven.
I can’t wait to try this it sounds just marvelous. And the serving piece the slice of cake is photographed on is so beautiful! Do you have any idea what the name of the pattern is? I made your rhubarb scones last weekend, and they were a hit! I think I’m going to try the strawberry lemon blondies next. Thank you so much!
Hope you love the cake Sheri, and the cake server is a thrifted find 🙂
Sue I have 3 questions. Can you use a spring form pan and I can’t find lemon paste and would love to make this is there something else to substitute? Can you add vanilla ?
I think this cake is best baked in cake pans, Christine. And yes, you can substitute vanilla, that would be delicious.
