Lemon Blueberry Cake Cream Cheese Frosting

The kitchen filled with this incredible bright citrus aroma while I was testing this recipe, and my neighbor actually knocked on the door to ask what I was baking. That moment sold me completely on the power of fresh lemon in baked goods.

I made this for my sisters baby shower last spring, and the pregnant women practically hovered around the cake table. My aunt asked for the recipe before she even finished her first slice, which is basically the highest compliment possible in our family.

Ingredients

• 2 1/2 cups all-purpose flour: Provides structure while keeping the crumb tender and light
• 2 tsp baking powder and 1/2 tsp baking soda: These work together for the perfect rise without any metallic aftertaste
• 1 cup unsalted butter, softened: Room temperature butter creates air pockets when creamed, leading to that delicate texture
• 1 1/2 cups granulated sugar: Sweetens while helping create a tender crumb structure
• 4 large eggs, room temperature: Essential for structure and richness, but they must be room temp to emulsify properly
• 1 tbsp finely grated lemon zest: This is where all the bright lemon flavor comes from, so zest thoroughly
• 1/4 cup fresh lemon juice: Adds tang and reacts with baking soda for extra lift
• 1 tsp vanilla extract: Rounds out all the flavors and adds depth
• 1 cup buttermilk, room temperature: The acidity tenderizes the gluten and creates a moist crumb
• 2 cups fresh blueberries plus 1 tbsp flour for tossing: Tossing in flour prevents them from sinking to the bottom during baking
• 8 oz cream cheese, softened: The star of the frosting, so use full fat for the best results
• 1/2 cup unsalted butter, softened: Balances the cream cheese and makes the frosting spreadable
• 3 cups powdered sugar, sifted: Sifting prevents lumps and ensures silky smooth frosting
• 2 tsp vanilla extract: Enhances all the flavors in the frosting
• 1 tbsp fresh lemon juice: Cuts the richness and adds a bright finish
• Pinch of salt: Balances sweetness and makes all flavors pop

Instructions

Preheat your oven to 350°F:

While the oven heats, grease and flour two 9-inch round pans, then line the bottoms with parchment paper for easy removal later.

Whisk the dry ingredients together:

In a medium bowl, combine flour, baking powder, baking soda, and salt until well blended.

Cream butter and sugar until fluffy:

Beat them for about 3 minutes until the mixture turns pale and fluffy, incorporating as much air as possible.

Add eggs one at a time:

Mix thoroughly after each egg, then add lemon zest, juice, and vanilla until everything is combined.

Alternate adding dry and wet ingredients:

On low speed, add flour mixture and buttermilk in three batches, starting and ending with flour, mixing only until just combined.

Prepare the blueberries:

Toss them with a tablespoon of flour, then gently fold into the batter to keep them evenly distributed.

Bake until golden:

Divide batter between the pans, smooth the tops, and bake for 30-35 minutes until a toothpick comes out clean.

Cool completely:

Let cakes rest in pans for 10 minutes, then turn onto wire racks to cool completely before frosting.

Make the luscious frosting:

Beat cream cheese and butter until smooth, then gradually add powdered sugar, vanilla, lemon juice, and salt until fluffy.

Frost and assemble:

Spread frosting between layers, then cover top and sides, decorating with extra blueberries and zest if you like.

Save

My dad, who claims not to like sweets, went back for seconds and then hovered near the cake plate the rest of the evening. Now he requests this specifically for his birthday instead of his usual chocolate cake.

Making It Ahead

I learned that wrapping the cooled cake layers tightly in plastic wrap and freezing them actually makes them even more moist. You can frost them frozen, which helps prevent crumbs in your frosting.

Serving Suggestions

This cake deserves to be the centerpiece of a spring brunch or summer potluck. The flavors brighten up even the grayest afternoon and make any occasion feel special.

Perfect Pairings

A slice of this cake with a cup of Earl Grey tea is basically my idea of heaven on a lazy Sunday afternoon.

• Try pairing with a crisp sparkling wine for a brunch that feels extra fancy
• Fresh mint leaves as garnish add a lovely pop of color and freshness
• Store any leftovers in the refrigerator, but bring to room temperature before serving

Hope this cake brings as much brightness to your kitchen as it has to mine. Happy baking.

Recipe Questions

→ Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work well in this cake. Do not thaw them before adding—toss with flour as directed and fold gently into the batter to prevent bleeding.

→ How should I store this cake?

Store the frosted cake in an airtight container in the refrigerator for up to 5 days. Bring to room temperature for 30 minutes before serving for the best texture and flavor.

→ Can I make this cake in advance?

You can bake the cake layers up to 2 days ahead and wrap tightly at room temperature. Frost the same day as serving, or freeze unfrosted layers for up to 3 months.

→ Why do room temperature ingredients matter?

Room temperature butter, eggs, and buttermilk emulsify better, creating a lighter, more tender cake crumb. Cold ingredients can result in a dense or uneven texture.

→ Can I substitute the buttermilk?

Mix 1 cup of milk with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5-10 minutes until slightly thickened. This works as an effective buttermilk alternative.
