Ingredients

Lemon Blueberry Cake

• 2 cups (265g) all-purpose flour
• 1 1/2 tsp baking powder
• 1/4 tsp baking soda
• 1/2 tsp salt
• 1/2 cup (120ml) whole milk, room temperature
• 1/3 cup (80ml) fresh lemon juice (from 3–4 medium lemons)
• 1 tablespoon lemon zest (from 1 medium lemon)
• 1 1/2 cups (300g) granulated sugar
• 1/3 cup (75g) unsalted butter, room temperature
• 1/4 cup (60ml) vegetable oil
• 3 large eggs, room temperature
• 2 tsp pure vanilla extract
• 1 cup (135g) fresh blueberries, divided
• 2 tsp all-purpose flour (for coating the blueberries)

Lemon Cream Cheese Buttercream

• 3/4 cup (170g) unsalted butter, room temperature
• 6 cups (720g) powdered sugar
• 2 tsp fresh lemon juice
• 12 oz (339g) full-fat brick-style cream cheese, room temperature
• Pinch of salt

Optional Garnish

• Fresh blueberries + thin lemon slices

Do not substitute cake flour for all-purpose flour in this recipe — the batter needs to be thick enough to keep the blueberries from sinking. Cake flour won’t do that. For the frosting, you must use full-fat brick-style cream cheese (not the spreadable kind in tubs), or the frosting will be too loose to work with.

Why These Ingredients Work

All-purpose flour creates a thicker batter than cake flour, which is the secret to keeping those blueberries from sinking to the bottom of every pan. It still produces a tender, moist crumb — trust the recipe!

Lemon juice added to whole milk creates a quick homemade buttermilk right in your measuring cup. The acidity reacts with the baking soda to help the cake rise while adding a subtle tanginess that makes the lemon flavor pop.

Butter + vegetable oil together is the best of both worlds. Butter brings flavor and richness; oil brings moisture that stays in the cake even after it cools. You get a soft, moist crumb that tastes incredible.

Adding the cream cheese last in the frosting is the game-changing technique here. It prevents the frosting from getting too soft and makes it stable enough to actually pipe beautifully onto the cake.

Tools Needed

• Three 6-inch or two 8-inch round cake pans
• Stand mixer with paddle attachment
• Parchment paper circles
• Wire cooling rack
• Offset spatula
• Piping bag + Wilton Tip 4B (optional, for decorating)
• Cake turntable (helpful but not required)

How To Make Lemon Blueberry Layer Cake

Step 1: Prep Your Pans and Oven

Preheat your oven to 350°F. Spray the sides of your cake pans with cooking spray and fit parchment circles to the bottoms. In a liquid measuring cup, combine the whole milk and lemon juice and set aside — it will curdle slightly, and that’s exactly what you want.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside while you work on the wet ingredients.

Step 3: Cream the Butter and Sugar

In your stand mixer, combine the granulated sugar and lemon zest and mix for about 1 minute — this releases the lemon’s essential oils right into the sugar, and the whole bowl will smell incredible. Add the butter and cream on medium speed for 2 minutes until light and fluffy. Pour in the vegetable oil and beat until combined and creamy, about 3 more minutes.

Step 4: Add Eggs and Vanilla

Add the eggs one at a time on low speed, mixing until each is incorporated. Add the vanilla extract, then turn the mixer to medium speed and beat for 1 minute.

Step 5: Add Dry and Wet Ingredients

Turn the mixer off and add all the flour mixture at once. Mix on low until just combined, then slowly pour in the lemon-milk mixture. Mix until just combined, about 30 seconds. Don’t overmix at this stage!

Step 6: Fold in the Blueberries and Bake

Toss your blueberries with 2 teaspoons of flour until coated. Set about 1/3 of them aside. Use a spatula to fold the remaining 2/3 into the batter, then divide the batter evenly between your prepared pans. Sprinkle the reserved blueberries on top of each pan and gently press them in. Bake for 30–35 minutes, until a toothpick comes out clean or with a few moist crumbs. Cool in pans for 5 minutes, then transfer to a wire rack to cool completely.

Step 7: Make the Lemon Cream Cheese Buttercream

Beat the butter on medium-high speed for 5 minutes until very light and creamy. Add about 1/3 of the powdered sugar and mix on low, then add the lemon juice. Add the remaining powdered sugar and mix until combined — it will look thick and crumbly right now, but keep going! Add the room-temperature cream cheese and salt and beat on medium speed for 2–3 minutes until completely smooth and fluffy. No lumps!

Step 8: Assemble and Frost

Level your cooled cake layers if needed. Fill and stack the layers with lemon cream cheese buttercream, then apply a thin crumb coat over the whole cake. Refrigerate for at least 30 minutes. Frost the outside of the cake to your desired style — a semi-naked finish lets those beautiful blueberry layers peek through. Add any decorative piping on top and garnish with fresh blueberries and lemon slices.

You Must Know

Reserve blueberries for the top of each pan. Folding all the blueberries into the batter means the heavier ones will sink no matter what. Keeping some to place on top right before baking keeps them suspended closer to the surface. You’ll see the difference in every slice.

Don’t overmix the batter once the flour goes in. Once you add the flour and lemon milk, mix only until just combined. Overmixing develops too much gluten and can make the cake dense and tough.

Check your baking powder freshness. This is the number one reason cakes don’t rise properly. If your baking powder is more than 6 months old, buy a fresh can before you start.

Amelia’s Secret: I mix the lemon zest directly into the granulated sugar first — before creaming with butter — and let it sit for a full minute while the mixer runs. This simple trick releases the lemon’s natural oils into the sugar, amplifying the citrus flavor throughout the entire cake.

Pro Tips & Mistakes to Avoid

Make sure all your ingredients are truly at room temperature. Cold butter won’t cream properly, and cold eggs can cause the batter to curdle. I usually set everything out about an hour before I start baking.

Cool the cakes completely before frosting. A warm cake will melt the cream cheese frosting and create a sliding, messy disaster. Patience here is absolutely rewarded.

Refrigerate after the crumb coat. This step is what makes the final frosting go on smoothly without dragging up crumbs. Don’t skip it!

Flavor Variations

Lemon Raspberry: Swap the blueberries for fresh raspberries and fold in a thin layer of raspberry jam between the cake layers along with the buttercream.

Lemon Lavender: Add 1 teaspoon of dried culinary lavender to the sugar-zest mixture at the start for a gorgeous floral twist on the classic lemon flavor.

Cupcakes: This batter makes a great cupcake too! Fill liners 2/3 full and bake at 350°F for 14–18 minutes. The recipe makes about 30–35 cupcakes.

Sheet Cake Version: Pour the batter into a greased 9×13 pan and bake at 350°F, checking for doneness at 30–35 minutes. Frost directly in the pan.

Make-Ahead

The cake layers can be baked 2 days ahead and stored at room temperature, wrapped tightly in plastic wrap. You can also freeze the wrapped layers for up to 2 months — thaw at room temperature before frosting.

The lemon cream cheese buttercream can be made up to 2 weeks ahead and stored in an airtight container in the refrigerator. When ready to use, bring it back to room temperature and re-mix until smooth and spreadable.

The decorated cake keeps in the refrigerator for up to 5 days; pull it out an hour or two before serving for the best flavor.

Serving Suggestions

Let the refrigerated cake sit at room temperature for at least 1–2 hours before slicing — it truly tastes better at room temp than cold straight from the fridge.

This cake is beautiful for Easter brunch, Mother’s Day, or a spring birthday.

Serve alongside a pitcher of sparkling lemonade, a pot of chamomile tea, or a light prosecco for the grown-ups.

How to Store

Store the finished cake covered in the refrigerator for up to 5 days. Because of the cream cheese frosting, it must stay refrigerated — don’t leave it at room temperature for more than 2 hours.

The cake layers (unfrosted) freeze beautifully for up to 2 months wrapped tightly in plastic.

Allergy Info

Contains dairy (butter, cream cheese), eggs, and gluten (all-purpose flour).

The vegetable oil is typically soy-based — check your brand if needed. For a dairy-free version, dairy-free butter and cream cheese can be substituted but results will vary.

For gluten-free, a 1:1 gluten-free flour blend may work, though the blueberry suspension results may differ.

Frequently Asked Questions

Why did all my blueberries sink to the bottom?

This happens for two reasons: the batter wasn’t thick enough (make sure you used all-purpose flour, not cake flour), or the blueberries weren’t coated in flour first. Both of these steps are essential. Also, reserving some blueberries to place on the very top of the batter before baking helps significantly.

My frosting is too soft to pipe. What happened?

The most common culprit is cream cheese that was too warm, or butter that was over-softened. Both should be at room temperature but firm — not melting. Try chilling the frosting in the fridge for 20–30 minutes and then re-mixing on low speed before attempting to pipe.

Can I use frozen blueberries?

For this particular recipe, fresh blueberries are strongly recommended. Frozen blueberries have extra water content that can make the batter too wet and affect how the cake rises. They also tend to bleed their color into the batter, turning it purple. Stick with fresh here if you can!

Can I make this as a two-layer 9-inch cake instead?

Yes! Use two 9-inch pans with the recipe as-is for thinner layers (about 1 inch tall each), or make 1.5x the recipe for taller, more impressive layers. Baking time stays about the same, so check for doneness at 30 minutes.

How far in advance can I make this cake?

You can bake the layers 2 days ahead and keep them wrapped at room temperature, or freeze them for up to 2 months. The decorated cake keeps in the refrigerator for up to 5 days. For the best flavor and texture, plan to frost it no more than a day before you want to serve it.
