How do you make Lemon Blueberry Cake with cream cheese frosting?

If cream cheese frosting is your thing, then I recommend baking the cake as a sheet cake or layer cake--it will make it easier to spread on the frosting. I also like to add a little lemon zest to the cream cheese frosting, but that's entirely up to you.

The Best Lemon Cream Cheese Frosting

  • 12 ounces cream cheese, at room temperature
  • 1 teaspoon lemon zest
  • 1 teaspoon lemon juice
  • 1 cup powdered sugar
  • 3/4 cup heavy cream
  1. In a large bowl using a mixer or by hand, beat together cream cheese, lemon zest, lemon extract, and powdered sugar. Set aside.
  2. Pour heavy cream into a separate clean, large bowl of a stand mixer. Beat on high until it holds shape and peaks form, about 3-4 minutes.
  3. Fold whipped cream into cream cheese mixture until no streaks remain.
  4. Spread frosting on top of cooled cake.

Lemon Blueberry Layer Cake and Sheet Cake tips:

Sheet cake, bundt cake, or layer cake, here's how to make Lemon Blueberry Cake delish.

  • To make a lemon blueberry layer cake: Divide batter between two 9 inch cake pans and bake at 350 degrees for 20-25 minutes.  Spread the whipped lemon cream cheese frosting in between cooled layers, along with some fresh blueberries.
  • To make a lemon blueberry sheet cake: Grease a 13 x 9 inch baking pan. Pour into prepared baking pan and bake at 350 degrees for 30-35 minutes, or until toothpick inserted in middle comes clean. If using glaze, poke holes in the cake with a wooden skewer so the glaze can run into the holes and flavor the cake. If using cream cheese frosting, allow the cake to cool before frosting.
  • To make lemon blueberry cupcakes: Line a 12 cup muffin tin with paper liners and set aside. Spoon the batter into the prepared muffin cups, filling them 3/4 of the way full. Bake at 350 degrees for 16-20 minutes, or until a toothpick inserted in the center comes out clean. Allow cupcakes to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. Once cupcakes are cool, frost and decorate.

The trick to bake the best, most lemony cake ever is something you might not expect, but it’s what makes this Lemon Blueberry Cake so completely, unbelievably spectacular.

How do you keep the blueberries from sinking into the bottom of the cake?

Tossing fresh or frozen blueberries in 1 tablespoon of flour before baking helps the blueberries stay dispersed throughout the cake and not sink to the bottom. Oh, and there's no need to thaw the frozen berries before adding to the batter--just throw them in!

Can I add extra blueberries?

Please use the recommended amount of blueberries as listed in the recipe. Adding too many might overwhelm your cake during the baking process; it might weigh the cake down and cause it to cook unevenly.

    What if the lemon cake mix already says it has pudding in the mix, do you still add the dry lemon pudding to it?

    1. Meggan

      Hi Fabre, I would think so. I haven’t personally tested this, but I imagine there wouldn’t be enough pudding mix in that cake mix to get the nice moist consistency of this recipe. Let me know how it works out! Thanks! Meggan

  2. Tami

    So easy to make and it comes out delicious! Thank you for sharing the recipe!5 stars

  3. Susan

    LOVED the cake….but it needed more than 40 minutes to bake. Only after adding extra time (Twice), which in turn caused the cake to fall and sink slightly did I see in the pre-amble that cook time was 1 hour.
    Please correct!!!!

    1. meggan

      Hi Susan, I’m sorry about that! Mine has always been done in 40 minutes, but I know oven times vary so I really need to put that in the recipe (a range for the time). Thank you for the feedback! Sorry again. -Meggan

    Yeah, so I completely missed the part about not adding too many blueberries. My cake was a total failure. It looked good in the oven, and it seemed done, but as soon as I took it out, it fell severely and looked awful. The blueberries had all sunk to the bottom and stuck to the pan and the cake around them was still moist and gooey. I was so heartbroken. I hate wasting ingredients. And making stupid mistakes.

    In this case, more was absolutely NOT better.

    So the glaze is a very simple recipe that would be very hard to mess up I would think. So I’m not sure why making the glaze based on your recipe came out extremely thick and paste like. There was no possible way to drizzle something that only had 3 tablespoons of water and half a teaspoon of vanilla. Not with 2 cups of sugar added. Luckily I had a tub of cream cheese frosting in the pantry. I haven’t officially eaten the cake yet, but I know it will be good because I licked the bowl after I poured the batter out. LOL

      Hi Kati, the recipe says to add 1 or 2 more teaspoons of liquid if you need it, to get your desired consistency. That’s really all it takes – 3 tablespoons of water and 1/2 teaspoon vanilla IS just about the amount of liquid you need for the glaze. But, after making it 8 times last weekend with different liquids and substitutions, I ended up changing it to 1/4 cup of water and 1 teaspoon vanilla for the 2 cups of powdered sugar. It’s super runny at that consistency, but I think that’s probably what most people will want. So thank you for helping me fix it up! I am glad I took the time to try a bunch of variations and stuff. I haven’t tried it with cream cheese but I definitely need to. Thank you Kati! -Meggan
