Blueberry cake with lemon cream cheese frosting is pure sunshine on a plate and always reminds me of summer celebrations with my family. The cake itself bursts with real blueberry flavor, and the tangy lemon cream cheese frosting takes it over the top. This is the cake I bake for birthdays and brunches when I want something special that everyone will ask about all day long.

I remember preparing this for my mom’s birthday and everyone gathered around waiting for a slice before it even had a chance to cool. The flavors and colors always make people smile.

Ingredients

  • Unsalted butter: softens the crumb and adds rich flavor Choose high quality butter for best results

  • Cake flour: ensures a light soft cake Sift for extra fluffiness If needed use a blend of all purpose flour with cornstarch
  • Baking powder and baking soda: help the cake rise evenly Use fresh leaveners for a beautiful crumb
  • Salt: balances sweetness and defines flavors Opt for fine sea salt
  • Sour cream: adds moisture and a subtle tang Select full fat for extra richness
  • Pureed blueberries: infuse the cake with vibrant color and fresh flavor Use plump ripe berries or quality frozen ones
  • Vegetable oil: keeps the cake moist and tender even after chilling Neutral oils like canola work best
  • Pink coloring gel (optional): for a bluer hue Choose a good gel that will not affect taste
  • Whole blueberries: folded into the batter create juicy blueberry bursts Toss in a bit of flour to prevent sinking
  • For the lemon cream cheese buttercream
  • Unsalted butter: forms the creamy base Use slightly softened butter for smooth mixing
  • Brick style cream cheese: provides a tangy flavor and silky texture Make sure it is very soft for easy blending

Step-by-Step Instructions

Prepare the Blueberries:
Puree fresh or thawed blueberries in a blender until mostly smooth Heat in a saucepan with water stirring often until the mixture reduces and thickens to three quarters cup Let the mixture cool completely before using This step creates a concentrated blueberry flavor that will not make the batter too runny
Prep the Cake Pans and Oven:
Preheat your oven to three hundred fifty degrees Fahrenheit and thoroughly grease and flour three round cake pans eight inches wide by two inches high This prevents sticking and helps the cakes pop out smoothly
Mix Dry and Wet Ingredients:
In a bowl whisk together the flour baking powder baking soda and salt for even distribution In another bowl stir the sour cream blueberry puree and vegetable oil until combined Mixing these separately allows everything to come together quickly and evenly in the final batter
Cream Butter and Sugar:
In a mixer bowl beat the softened butter until completely smooth and creamy Slowly add sugar and continue to mix until the mixture is very light and fluffy usually about three to five minutes Scraping the bowl ensures even texture This is key for airy cake
Add Eggs Gradually:
Crack eggs in one at a time mixing on low after each until the yolk disappears This steady pace helps the batter stay smooth and prevents curdling
Alternate Adding Dry and Wet Mixes:
Add one third of the dry ingredients to the butter mixture mix gently then add half of the blueberry sour cream mixture Alternate in this pattern ending with a final addition of dry ingredients Stir each time only until just blended for a tender cake Do not overmix
Color and Fold in Blueberries:
If desired add a drop or two of pink coloring gel to enhance the purple hue Gently fold in whole blueberries with a spatula They create juicy pockets without sinking to the bottom
Bake and Cool:
Divide batter across prepared pans and bake for twenty two to twenty five minutes Test the center with a toothpick for doneness The cakes should spring back and a few moist crumbs are fine Cool in the pans for about ten minutes before turning out to finish cooling on a rack
Make Lemon Cream Cheese Frosting:
Beat softened butter in your mixer until smooth Add soft brick cream cheese in pieces and mix gently until fully incorporated Sift and gradually add powdered sugar then pour in lemon juice and zest Keep mixing on low until creamy and thick Avoid overmixing or the frosting may become too soft If needed refrigerate briefly to firm up
Frost and Serve:
Once cakes are completely cool spread the lemon cream cheese frosting generously between each layer and all around the outside Decorate with fresh blueberries or lemon zest if desired

My favorite ingredient here is the pureed cooked blueberries that infuse every part of the cake with rich fruitiness Without this step you miss out on the depth of true blueberry flavor My niece loves to help swirl the purple batter and always asks to sneak a taste

Storage Tips

Store any leftovers in an airtight container in the fridge The frosting keeps the cake moist for several days For longer storage you can wrap unfrosted cake layers tightly in plastic and freeze up to two months then thaw and frost just before serving For best flavor serve chilled but allow to sit at room temperature for ten to fifteen minutes before slicing

Ingredient Substitutions

If you do not have cake flour make your own by replacing a small amount of all purpose flour with cornstarch as described above Greek yogurt can replace sour cream for a similar texture If you run out of fresh blueberries high quality frozen berries work beautifully just thaw and drain first to prevent extra moisture Lemon extract can boost citrus flavor if zest is not available

Serving Suggestions

This cake shines as a centerpiece for summer cookouts baby showers or special brunches For a festive touch garnish with extra blueberries lemon zest or edible flowers Serve with coffee tea or even a chilled glass of sparkling lemonade

How to Make It

Step 01

Measure 198g blueberries and puree. Cook with 60ml water over medium heat until reduced to 181g. Cool the reduction completely before use. Preheat oven to 175°C. Grease and flour three 20cm x 5cm round cake pans. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. In a separate bowl, combine sour cream, blueberry puree, and oil, then blend with a fork. In a mixer, cream butter until smooth. Gradually add sugar and beat on medium speed for 3-5 minutes until fluffy. Add eggs one at a time, mixing until combined. Alternately add the dry and wet mixtures, starting and ending with the dry ingredients. Add pink coloring gel if desired. Mix until smooth, then gently fold in 66g whole blueberries. Divide batter evenly into prepared pans. Bake for 22 to 25 minutes or until a toothpick inserted in the center comes out clean. Cool cakes in pans for 5-10 minutes, then turn out onto wire racks to cool completely.

Step 02

In a mixer, beat softened butter until smooth. Gradually add cream cheese pieces and mix until fully combined. Add powdered sugar in increments, followed by lemon juice and zest. Mix until smooth, avoiding overmixing. If the frosting becomes too soft, refrigerate for 10 minutes before using.
