This lemon blueberry cake starts with a moist & tender lemon cake that’s dotted with juicy blueberries. Then it’s topped with cream cheese frosting that has just a hint of lemon. It’s a simple recipe that’s easy to make and perfect for spring & summer.
Last week I asked on Instagram what flavor combo you prefer: lemon blueberry or lemon raspberry.It was pretty neck-and-neck, but lemon blueberry came out on top. And hence, this lemon blueberry cake recipe was born. It has a deliciously tender & soft texture, zero dry cake crumbs, a bright & sunshineylemon flavor, and tons of juicy blueberries.Then the cream cheese frosting is oh so creamy and not too sweet.
Lemon and blueberries make for such a delicious flavor combination. The slight tang of the lemon is the perfect complement to sweet, juicy, extra plump blueberries. (For some reason I always chuckle at the idea of “plump berries”). And if you love the flavor combo as much as my Instagram buddies (HI!!!!!) – then you’ll love this recipe.
Lemon Blueberry Cake Recipe
This lemon blueberry cake recipe is made in a 9×13 inch pan, so it’s much easier than making a layer cake. There’s a few key ingredients in this recipe that make it extra moist & tender, so let’s talk specifics.
- Real butter – not margarine, not that 50/50 stuff. We use real butter for the most flavor, and to ensure that the cake doesn’t taste oily. Make sure the butter is softened to room temperature first so that everything mixes together evenly.
- 3 large eggs for tenderness. Some cake recipes just use the egg whites. This makes for a much more delicate, airy texture. But when you want it perfectly moist and tender – I like recipes that use the whole egg.
- Cake flour for an extra soft, never dense cake crumb. I realize that not everyone has cake flour on hand in their kitchen, so I’ve included a substitute in the notes using all-purpose flour and cornstarch, although I definitely recommend using cake flour if possible. Just make sure that you don’t substitute all-purpose flour for cake flour as a 1:1 ratio. Otherwise, the cake with be dry and dense.
- Buttermilkfor a moist, tender, super soft cake. Make sure it’s room temperature first – by either leaving it on the counter for 15 minutes to warm up, or microwave in short 10 second bursts on low-medium power. If you don’t have buttermilk, I’ve included a substitute in the notes. But I really, really recommend using buttermilk if possible.
- Lemon juice & lemon zest for that delicious flavor. Make sure to use lemon juice from freshly squeezed lemons as opposed to the stuff from the bottle for a tart, bright flavor that doesn’t taste sour.
- Feel free to use fresh or frozen berries. If using frozen, just make sure not to thaw them first.
Then the cream cheese frosting is an easy, peasy, simple recipe made with butter, cream cheese, powdered sugar, a little lemon juice and cream. Make sure to use brick-style, full-fat cream cheese, and allow both the cream cheese and butter to soften to room temperature before getting started.
Now for a few common questions:
Can I make this into a lemon blueberry layer cake? Yes. It’s enough for a 2-layer 8 inch layer cake. Line the bottom of the cake pans first, then grease the sides. They’ll take about 21-25 minutes to bake.
Can I turn this recipe into lemon blueberry cupcakes?Yup. Fill each cupcake liner about ⅔ fulls, and bake at 350F for for 16-20 minutes. You’ll end up with about 18-20 cupcakes total.
How can I make this recipe ahead of time?Make the cake and frosting up to 1 day in advance. Cool the cake completely then wrap tightly and store at room temperature, and store the frosting in an airtight container in the fridge. When ready to frost, let the frosting warm up to room temperature first. You may need to beat the frosting again with the mixer if it seems too hard/thick to frost. Unfrosted cake can be wrapped tightly and frozen for up to 2 months, then thaw overnight in the fridge.

In a liquid measuring cup whisk together the lemon juice and buttermilk.
With the mixer on low speed, beat about ⅓ of the flour mixture into the butter mixture followed by about ⅓ of the milk mixture.
Continue the process of alternating between the flour & milk until just combined, turning off the mixer and scraping down the sides of the bowl as necessary.
Toss the blueberries with the 2 teaspoons of flour, then gently fold into the batter with a spatula.
Pour the batter into the prepared pan.Bake for 25-30 minutes, or until an inserted toothpick comes out clean.
Cream Cheese Frosting
Beat the butter until soft, then mix in the cream cheese.
Add in the lemon juice and mix in 3 cups of the powdered sugar, starting with the mixer on low speed and then turning up to medium as it starts to combine.
Beat in 1 tablespoon of whipping cream, and then mix in the rest of the powdered sugar as necessary, going little by little and adding more cream if needed.
Frost the cooled cake, and optionally decorate with blueberries and lemon slices.

How do you think the frosting would be if I used honey instead of sugar?
Reply
- Fiona
I think the frosting would end up very sticky and runny, unfortunately. Because honey is a liquid, it can’t really be used as a substitute for sugar in frosting.

Would a regular white cake mix be ok?
Reply
- Fiona
I haven’t tried it – so I really can’t say for certain. Because it wasn’t developed using cake mix, I’m not overly optimistic that it would turn out.

So yummy ! I used regular flour because I didn’t read the tip at the bottom. I also used yogurt instead of buttermilk. I did have to cook it longer but both the cake and frosting were amazing !!! My husband doesn’t even like cake and he liked it !Reply

Hi! Super excited to try this. I saw that at the top of the ingredients list it has 2 1/4 cups cake flour and then 2 teaspoons of cake flour at the bottom. How much cake flour should go into this?
Thanks!

Hi Alyssa,
Sorry for the confusion! You’ll add 2 1/4 cups of cake flour when you whisk together the dry ingredients in step 2. The extra 2 teaspoons of cake flour is used in step 8 to toss the blueberries in. Tossing the blueberries in just a little flour helps to minimize the risk of them bleeding blue color into the batter. It also helps the berries to “stick” into the batter so that they don’t sink to the bottom. I hope this helps.

Holy Sweet Lord Baby Jesus this cake is TO DIE FOR! I didn’t have buttermilk so I did the ol faithful lemon juice and milk and let it sit for 10 minutes and let me tell you, I think this cake would be delicious with even just plain milk! I did cheat and use store bought frosting (which I NEVER do!), only because I was pressed for time. But Oh My Lanta, this will be in my very particular and carefully chosen favourite cake recipe arsenal for all time! Thank you so so much for sharing this Fiona!! Love from Alberta, Canada!

I don’t have any unsalted butter, can I use salted butter instead?
Reply

That would be fine, just omit the salt from the recipe

Hello! Would this cake hold for a tiered birthday cake? Just not sure on how dense it is? Thank you so much! It sounds delicious.
Reply
- Fiona
Hi Stephanie,
It would hold for a 2 or 3 layer cake. I’m not 100% sure of how long the bake time would be.

Brought this cake to a party and got rave reviews! It was moist and delicious! I tasted the frosting and it was a little tart so I added a teaspoon of vanilla. I may also add more blueberries the next time! Definitely making this again soon!Reply

Have you tried halving the recipe? Excited to try this!
Reply

You could half the recipe and bake in an 8×8 inch pan – I think the bake time would be a few minutes less.

Making for tomorrow, it’s complete cooled/frosted.
Do I store this in the fridge overnight?Reply
- Fiona
I would store it in the fridge, then take it out of the fridge about 30-60 minutes before serving and let it come to room temperature
