How to Make Lemon Blueberry Cake
You can find the full, printable lemon blueberry cake recipe further down in this post, but here is a quick rundown of our steps!
- Preheat the oven to 350 degrees F. Grease and flour three 8 inch round pans. I also like to line them with circles of parchment paper.
- In a medium sized bowl add these dry ingredients: cake flour, baking powder, baking soda and salt. Whisk to blend, set aside.
- In another bowl or measuring cup combine the sour cream, lemon juice and lemon zest, vanilla extract and lemon extract and set aside.
- In the bowl of your mixer, mix the softened unsalted butter until smooth. Next, slowly add the sugar and mix on medium speed for 3 to 5 minutes until fluffy.
- Add the room temperature eggs one at a time, mixing until the yellow of the yolk disappears.
- Add the flour mixture and the sour cream mixture alternately, beginning and ending with flour mixture (three additions of dry ingredients and two of wet). Mix until combined, do not mix above medium speed or overmix.
- Toss the blueberries in 1 Tablespoon flour and gently fold into the cake batter. The cake batter is very thick (as it is based in part on our white almond sour cream cake). Divide the batter between the 3 pans smoothing the tops with the back of a spoon.
- Bake at 350 degrees for 25 to 28 minutes or until a toothpick inserted into the center comes out clean or with just a few crumbs attached. Let the cakes cool on a wire rack for 5-10 minutes before turning out.
Assembling the Cake
We decided to boost the lemon and blueberry flavors in this lemon blueberry cake recipe with our luscious lemon cream cheese frosting in between the cake layers as well as a delicious blueberry buttercream!
We absolutely love cream cheese frostings. However, there are other options as well! Feel free to change things up as you like! A lemon curd or lemon buttercream filling would taste great too!
Piping a Dam
Since our lemon cream cheese filling is a bit soft, I piped a blueberry buttercream dam about ¼ inch inside of the edge of the cake before filling. This helps to keep the filling right where it belongs as the layers are assembled.
Blueberry Buttercream Frosting
In this frosting recipe, you'll see that the blueberry buttercream's key ingredient is a flavorful blueberry syrup, which is a simple reduction. We love this delicious recipe as well as its speckled appearance!
With this recipe, you will have plenty of extra frosting for decorative piping, borders, etc.
Decorating the Lemon Blueberry Cake
Decorate the cake however you like! Our blueberry buttercream is very easy to work with. After crumb coating the assembled cake in a thin layer of frosting, I used a star tip 21 to make patterns of overlapping rosettes and vertical lines. (For more details on working with a star tip, check out our star tip piping tutorial!)
Here is a peek inside. This cake is ultra moist with a tender crumb and wonderful flavor. Keep it in mind the next time you need a birthday cake recipe, holiday cake, potluck dessert, and more!

Lemon Blueberry Cake
Equipment
Ingredients
For the Cake
- 2 sticks unsalted butter, softened (226g) Shouldn't be overly soft, but soft enough to easily dent when pressed.
- 2 cups sugar (400g)
- 3 large room temperature eggs (if in a hurry, place the eggs in a bowl of warm water for 5 minutes)
- 1 cup sour cream (242g)
- ⅓ cup juice and zest of 2 lemons
- 1 teaspoon vanilla extract (4g)
- 1 Tablespoon lemon extract (10g)
- 3 cups cake flour (plain in the UK) — if you do not have cake flour see substitution below (342g)
- 1 ½ teaspoons baking powder (7g)
- ½ teaspoon baking soda (3g)
- ½ teaspoon salt (3g)
- 1 ½ cups wild blueberries tossed in 1 Tablespoon flour — Keep the berries frozen until just before stirring in. Wild blueberries are smaller and are less likely to sink in the cake batter. You can use fresh or frozen I usually use frozen.
For the Blueberry Syrup
- 1 cup blueberries (125g)
- 2 Tablespoons sugar (27g)
- ¼ cup water (57g)
For the Blueberry Buttercream Frosting
- 3 sticks unsalted butter, softened (354g)
- 7 ½ cups 863g powdered sugar
- 2 teaspoons vanilla (8g)
- ½ to 1 teaspoon salt optional to cut sweetness
- ¼ cup plus 2 tablespoons blueberry syrup- more if needed to reach your desired consistency
For the Lemon Cream Cheese Filling
- 1 sticks unsalted butter, slightly softened (113g)
- 8 oz Cream Cheese (Do not use reduced fat or cream cheese in the tub containers. Soften very slightly.)
- 1 teaspoon lemon juice (4g)
- ½ teaspoon lemon extract, optional (2g)
- Zest of One Lemon approximately 1.5 teaspoons 3g
- 3 to 3 ½ cups 345g - 374g powdered sugar, adding more if necessary
Instructions
For the Cake
- Preheat the oven to 350 degrees F, grease and flour three 8x2 inch round cake pans. Three layers will give you slightly shorter layers but more filling per slice.
- In a medium sized bowl add the flour, baking powder, baking soda and salt. Whisk to blend, set aside.
- In another bowl or measuring cup add the sour cream, lemon juice and zest, vanilla and lemon extract. Blend with a fork and set aside
- In the bowl of your mixer, beat the softened butter until smooth. Gradually ad the sugar and beat on medium speed for 3 to 5 minutes until it is lightened in color and fluffy.
- Add the eggs one at a time, mixing until the yellow of the yolk disappears.
- Add the flour mixture and the sour cream mixture alternately, beginning and ending with flour mixture (3 additions of dry ingredients and 2 of wet). Mix until combined and smooth, do not mix above medium speed or over mix.
- Toss the blueberries in 1 Tablespoon flour and gently fold into the cake batter. The cake batter is very thick. Divide the batter between the 3 pans smoothing the tops with the back of a spoon.
- Bake at 350 degrees for 25 to 28 minutes or until a toothpick inserted into the center comes out clean or with just a few crumbs attached. Let the cakes cool 5 to 10 minutes then turn out.
- Makes 7 cups cake batter
- (This recipe works well for cupcakes too)
For the Blueberry Syrup (Used in the Buttercream)
- To a saucepan add the above ingredients and cook over low heat until sugar dissolves. Increase to medium heat and cook until the mixture is reduced a bit. Cool the syrup before using in the buttercream. It can be refrigerated 3 to 5 days in the refrigerator.
- INSTRUCTIONS FOR BLUEBERRY BUTTERCREAM
- Cream the softened butter until smooth. Blend in the vanilla.
- Gradually add the powdered sugar and blueberry syrup until the powdered sugar is incorporated . Mix on medium speed 4 to 6 minutes or until smooth. Slowing the mixer down to a low speed setting during the last minute of mixing helps to eliminate air pockets.
- Makes 6 cups frosting
For the Lemon Cream Cheese Frosting
- Cut butter into ½ inch slices and add to the bowl of your mixer, beat until smooth.
- Cut the cream cheese into pieces and add to the butter, beating until blended.
- Add the lemon juice and lemon zest. ½ teaspoon lemon extract, (optional) for a stronger lemon flavor.
- Gradually add powdered sugar and beat until well blended.
- This frosting will pipe best if used while still chilled. You can make it in advance, refrigerate and when ready to use let it soften slightly and remix. Do not microwave to soften.
Assembly
- Place the first layer on your pedestal or cake base. Pipe a dam of blueberry buttercream about ¼ inch within the edge of your cake layer and fill with lemon cream cheese frosting.
- Add next layer and repeat.
- Frost the cake with blueberry buttercream. I like to apply a thin crumb coat layer first, and then follow either with a second layer of frosting, or with piping as I did in today's cake. I used a star tip 21 to create the piped designs. Due to the cream cheese frosting, this cake should be refrigerated until within a few hours of serving.
I plan to make this cake next. I just really love your cakes!! I have a question about overmixing. After adding in the eggs, about how long should I mix so that I don't overmix the batter? Thank you.
Hi Rachel, Thank you for your nice comment, I'm happy you are going to bake this cake. You will add the eggs 1 at a time and mix until the yellow of each yolk is disappears. At this point begin adding the flour mixture alternately with the sour cream mixture. You will mix the first addition of dry ingredients until the they are blended in, the same for the sour cream mixture and so on until all ingredients are mixed. You may need to mix another minute or until the batter looks smooth. Do not mix above medium speed. I usually mix at number 3 or 4 on my Kitchen Aid stand mixer. If you are using a hand held mixer, you may need to mix a bit longer than you would with a stand mixer. I hope you will enjoy the cake.
Love this recipe! It got rave reviews at my daughter's Birthday party! Went with a Pineapple fiing instead of lemon, and made it Sofia the First style
Hi CJ, Such a pretty cake and I love the presentation. Thanks so much for posting the picture!
In the recipe where it says "1/3 cup - juice and zest of two lemons", is the 1/3 cup made up of the juice and zest together, or it is a 1/3 cup of juice and a 1/3 cup of zest? Thanks.
Hi Rachel, 1/3 cup of lemon juice, plus the zest of two lemons ;0)
Thank you so much!
This cake looks delicious! My husband has requested a Lemon Blueberry Cake and this one came up on Pinterest. I was reading through the post above and the batter is mentioned as being thick. Does that make the cake dense or is it light and fluffy? I am just wondering about the texture? Thank you.
Hi Alyssa, The cake batter is thick and this keeps the blueberries from sinking to the bottom of the pan. A thick batter does not make the cake dense. Also, we used frozen wild blueberries that are smaller. We think this is a delicious cake, I hope you will give it a try.
It has been a month since I had time to bake a cake, and I chose this one. I am so happy I did. It is DELICIOUS!! The texture of it is amazing! I was planning to carry the rest of it to a get together with some friends tonight, but now I want to keep it all for myself. :) It is wonderful! I love that the blueberries do not all sink to the bottom but are distributed throughout the whole cake. I did not make the blueberry buttercream but did a cream cheese flavored buttercream instead. I highly recommend this cake. If you are looking for a superb tasting lemon blueberry cake, this is the one.
Hi Rachel! Thanks so much for your feedback, I'm so glad that you enjoyed it!
I love your website; so glad I found you! :)
I plan to make a friend a Lemon Blueberry sheet cake in a couple of days. I see you have Lemon Blueberry Cupcakes using cake mix and this one here from scratch. Can the cupcake version work for a 13 x 9 sheet cake, if I want to stick to the 'doctored' type? Or do you think only the scratch recipe would work best for a sheet cake? Any significant differences to make me decide since they both look good to me?
Thanks Mary! Yes, no problem to use the doctored cake mix version as a sheet cake! ;0) The instructions on the back of the box will give you some guidelines on about how long it should bake. Hope you enjoy it!
I know you can't make any promises but do you think this recipe would work with raspberries instead of blueberries? I have a request for a lemon raspberry cake. Thanks!
Hi Tiffany! Yes, I don't see why not-hope you enjoy it!
The raspberries worked. It was my first time making a cake for someone that wasn't family and thanks to your recipe, it was a hit! Thank you very much!!
Hi Tiffany, that is great! Thanks for your feedback- your cake looks beautiful!
se ve que es muy delicioso leyendo las instrucciones se me hizo agua la boca
