    Easy Lemon Blackberry Cake Recipe

    Just in time for your summer celebrations, this lemon and blackberry cake is a fantastic way to showcase summer berries for a special occasion! This cake is so moist and full of bright flavors, and it's got a velvety blackberry buttercream frosting that makes it truly irresistible!

    I really love baking with lemon, so this cake is a favorite recipe of mine! It's based on my Lemon Coconut Layer Cake from my summer cookbook! But for this cake, I added fresh, sweet blackberries to balance out the tartness of the lemon, and the balance of flavors was fantastic.

    What to do with lots of blackberries?

    Summer berry season is such an amazing time of year, and there's nothing better than picking a big batch of fresh, ripe blackberries or grabbing some at the farmer's market! And if you're looking for something to do with all those berries, this lemon and blackberry cake is your best bet! We're folding in fresh blackberries into the cake batter, and topping it all off with a blackberry buttercream frosting made with more fresh blackberries! If you're a berry lover, you will adore this cake!

    What does lemon do to a cake?

    So what happens when you add lemon juice to cake batter? Well first of all, the lemon in this cake adds a nice bright, citrus flavor that complements the sweetness and tartness of the blackberries so perfectly! And the lemon also works with the baking soda in the cake batter to give this easy lemon blackberry cake a nice, fluffy texture.

    Moist Blackberry Cake Ingredients

    • lemon zest - adds that bright, tangy lemon flavor! Make sure you use a microplane zester and only zest the top layer of the lemon peel. I recommend using organic lemons because conventional lemons can have a waxy coating that prevents your cake from getting that maximum lemony flavor!
    • granulated sugar - we'll press the lemon zest into our granulated white sugar to make sure all of those lemon oils are released.
    • butter - I like to use salted butter in most of my cake recipes, but if you prefer to use unsalted, just add ¼ teaspoon of salt in with your dry ingredients.
    • eggs - your eggs should be room temperature before adding them to this lemon and blackberry cake recipe.
    • vanilla extract - be sure to use a high-quality pure vanilla extract. Or better yet, check out my post on how to make vanilla extract at home with just 2 ingredients!
    • vegetable oil - I like to use canola oil, but any light-flavored vegetable oil works well.
    • cake flour - cake flour is great in this lemon and blackberry cake because it produces a light, moist crumb. If you don't have cake flour on hand, see the tips below for a cake flour substitute!
    • baking soda and baking powder - these leaveners help to give our cake a nice lift!
    • blackberries - I like using fresh blackberries in this cake, but you can also thawed and drained frozen blackberries.
    • sour cream - adds a nice moisture to this lemon and blackberry cake!
    • fresh lemon juice - juice those lemons that you zested earlier.

    For the Blackberry Buttercream Frosting

    • blackberries - frozen or fresh work fine, but you may want to thaw them from frozen to make them easier to purée.
    • fresh lemon juice - helps to add a nice tartness and complements the blackberry flavor perfectly!
    • butter - as above, if you prefer to use unsalted butter, just toss in ¾ teaspoon of salt to balance out the sweetness in this frosting.
    • powdered sugar - just like with our cake flour, you'll want to measure your powdered sugar by weight with a kitchen scale, or with the spoon-and-level method.
    • vanilla extract - to round out the flavor in this blackberry buttercream!

    Equipment

    For this 8-inch layer cake, you'll need three 8-inch cake pans -- these are my favorite! And I'd recommend a stand mixer to whip up your batter, as well as a microplane for zesting!

    Tips and F.A.Q.

    What makes a cake moist and fluffy?

    In this lemon and blackberry cake, the first secret is sour cream! The richness and acidity of sour cream ensures a soft, fluffy cake that stays moist! Another key step is adding a bit of vegetable oil for an even moister cake.

    How do you add lemon flavor to a cake?

    This lemon and blackberry cake uses lemon zest and lemon juice to create a bright lemon flavor! Many dessert recipes use lemon extract, which you could also add here if you really want to amp up the lemon flavor!

    What does lemon cake taste like?

    This blackberry lemon cake has a bright, yet subtle lemon in the batter, with a boost of lemony flavor in the lemon curd filling.

    Can I use frozen blackberries for this lemon and blackberry cake?

    You sure can! I like to thaw them and drain them so that they don't add too much liquid to the cake batter. For the blackberry buttercream frosting, you may not need to drain them since they'll be puréed.

    Can I use store-bought lemon curd?

    Absolutely! Homemade lemon curd always has the best flavor, but when you're filling this blackberry lemon cake with lemon curd, store-bought works just fine.

    What if I don't have cake flour?

    If you don’t have cake flour, you can make a substitute to use in this moist blackberry cake recipe! All you need is all-purpose flour and corn starch. Just measure out 2 ½ cups of all-purpose flour and replace 5 tablespoons of it with cornstarch. In grams, it’ll be 312 grams of all-purpose flour sifted with 40 grams of cornstarch. As I mentioned above, it’s best to measure by weight with a kitchen scale, but if you don’t have one be sure to use the spoon-and-level method to measure by volume.

    How do I store this lemon and blackberry cake?

    Unfrosted cake layers can be made and stored at room temperature, wrapped in plastic wrap, for up to two days. They can also be frozen for up to 2 months, wrapped well in plastic wrap and heavy duty foil. 

    Once frosted, the cake can be stored in an airtight container at room temperature up to 2 days, and should last in the fridge in an airtight container up to 4 days.

    Notes

    Blackberries: Feel free to use frozen blackberries in either the cake layers or the blackberry buttercream frosting. Just be sure to thaw and drain the blackberries before adding to the recipe.
    Lemon Curd: You can use either store-bought lemon curd, or make your own at home! Check out my Lemon Curd Cookies recipe for my recipe for homemade lemon curd! Prepare your lemon curd a few hours or a day in advance to allow it to set fully before assembling your lemon and blackberry cake!
    Cake Flour Substitute: If you don’t have cake flour, you can make a substitute to use in this lemon and blackberry cake recipe! All you need is all-purpose flour and corn starch. Just measure out 2 ½ cups of all-purpose flour and replace 5 tablespoons of it with cornstarch. In grams, it’ll be 312 grams of all-purpose flour sifted with 40 grams of cornstarch. As I mentioned above, it’s best to measure by weight with a kitchen scale, but if you don’t have one be sure to use the spoon-and-level method to measure by volume.
    Sour Cream Alternatives: If you don't have full-fat sour cream, you can use greek yogurt, or a low-fat sour cream as an alternative.

      Made this for my blackberry-loving daughter's first birthday party and it was a HUGE hit, especially the buttercream. I made a 9x13 sheet cake and 6 cupcakes instead of layers so we could serve to a group, so I omitted the lemon curd. If you do this you can easily get away with making a 3/4 recipe of the frosting but it's not going to be a hardship to use up the leftovers! It would have also fit into just the 9×13 pan. The only other change I made was to add a package of Trader Joe's freeze dried blueberries (ground in a spice grinder) to the buttercream so I could get a more intensely purple-y color. Thanks a always for the super detailed instructions and notes.
