What Ingredients You Will Need

This Moist Lemon Blueberry Layer Cake uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most of these are pantry staples, with fresh lemons and blueberries bringing in that seasonal brightness.

• For the Cake Batter:
  • 2 ½ cups (315g) all-purpose flour (I recommend King Arthur Flour for best texture)
  • 2 ½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup (230g) unsalted butter, softened (adds richness and moisture)
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (240ml) buttermilk, room temperature (for tender crumb)
  • 2 tbsp freshly grated lemon zest (the star of the show!)
  • ¼ cup (60ml) fresh lemon juice
  • 1 ½ cups (225g) fresh or frozen blueberries (if frozen, do not thaw to prevent color bleed)
• For the Creamy Buttercream Frosting:
  • 1 cup (230g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 2 tbsp fresh lemon juice
  • 1 tsp vanilla extract
  • 2-3 tbsp heavy cream or milk (adjust for desired consistency)
  • Pinch of salt (to balance sweetness)

Note: For a dairy-free option, swap butter with a vegan alternative and use coconut milk instead of heavy cream. Use almond flour for a gluten-free twist, but the texture will be a bit different. When it’s summer, swapping fresh blueberries for raspberries or blackberries can add a lovely change.

Equipment Needed

• Two 8-inch (20 cm) round cake pans (non-stick or lined with parchment paper works great)
• Electric mixer (stand or hand) for smooth batter and fluffy frosting
• Mixing bowls of various sizes
• Measuring cups and spoons (precision matters here!)
• Rubber spatula for folding blueberries gently
• Cooling racks to cool the cakes evenly and prevent sogginess
• Offset spatula or butter knife for frosting application

If you don’t have cake pans, you can use springform pans, but the baking time might adjust a bit. I’ve also made this recipe with a hand mixer when the stand mixer was busy, and it worked just fine—just be patient while beating the butter and sugar.

Preparation Method

1. Preheat your oven: Set to 350°F (175°C). Grease your two 8-inch cake pans and line the bottoms with parchment paper. This prevents sticking and helps the cakes release cleanly.
2. Mix dry ingredients: In a medium bowl, whisk together 2 ½ cups all-purpose flour, 2 ½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt. This ensures even rising and no surprises later.
3. Cream butter and sugar: In a large bowl, beat 1 cup softened unsalted butter with 1 ¾ cups granulated sugar using an electric mixer on medium speed until light and fluffy—about 3-4 minutes. This step is key for that tender crumb.
4. Add eggs: Beat in 4 large eggs one at a time, mixing well after each addition. This keeps the batter smooth and well combined.
5. Incorporate lemon zest and juice: Stir in 2 tbsp lemon zest and ¼ cup fresh lemon juice. The room fills with the most amazing bright citrus scent here—honestly, it’s the best part!
6. Alternate adding dry ingredients and buttermilk: Gradually add the dry flour mixture in three parts, alternating with 1 cup buttermilk (start and end with flour). Mix gently on low speed to avoid overmixing, which can make the cake tough.
7. Fold in blueberries: Using a rubber spatula, gently fold in 1 ½ cups fresh or frozen blueberries. Be careful not to break them up too much to keep the batter pretty and avoid turning it purple.
8. Divide batter and bake: Pour the batter evenly into the prepared pans. Tap the pans gently on the counter to release air bubbles. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
9. Cool the cakes: Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely before frosting. This prevents your buttercream from melting and sliding off.
10. Make the buttercream frosting: Beat 1 cup softened butter on medium speed until creamy. Gradually add 4 cups powdered sugar, mixing slowly at first to avoid a sugar cloud. Add 2 tbsp lemon juice, 1 tsp vanilla extract, 2-3 tbsp heavy cream, and a pinch of salt. Beat on high until fluffy and spreadable—about 3-5 minutes. Adjust cream to reach your desired consistency.
11. Assemble the cake: Place one cake layer on your serving plate. Spread a thick, even layer of buttercream on top. Add the second cake layer and frost the top and sides smoothly. Add extra lemon zest or fresh blueberries on top for garnish if you like.

Cooking Tips & Techniques

When making this Moist Lemon Blueberry Layer Cake, a few tricks make all the difference. First, don’t rush the creaming of butter and sugar—this step traps air that helps the cake rise beautifully. Also, keep your ingredients at room temperature; cold eggs or butter can cause the batter to curdle or not combine well.

Folding in blueberries gently is key. You want to avoid bursting them, which can turn your batter a dull purple instead of showcasing those pretty pops of blue. If you’re using frozen berries, add them straight from the freezer to minimize color bleeding.

Timing is everything: baking too long dries out the cake, too short and it’s gooey in the middle. Use a toothpick test and watch closely after 30 minutes. I’ve learned the hard way that ovens vary, so keep an eye on that golden crust.

When frosting, make sure your cake layers are completely cool—warm cake plus buttercream equals a melty mess. If your buttercream feels too thick, add a splash of cream; too thin, add more powdered sugar. It’s all about that perfect spreadable texture.

Variations & Adaptations

This recipe is flexible and open to your creativity. Here are a few ways to make it your own:

• Gluten-Free Version: Swap all-purpose flour for a gluten-free blend like Bob’s Red Mill 1-to-1. The texture will be slightly different but still delicious.
• Vegan Adaptation: Use vegan butter and substitute eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg). Swap buttermilk with almond milk and a splash of vinegar.
• Seasonal Fruit Twist: Replace blueberries with fresh raspberries, blackberries, or even chopped strawberries for a summer variation.
• Different Frosting: Try cream cheese frosting for a tangier finish or whipped coconut cream for a dairy-free option.
• Mini Cakes or Cupcakes: Divide the batter into cupcake liners for individual portions; adjust baking time to about 18-22 minutes.

Personally, I once tried adding a sprinkle of poppy seeds into the batter for a little crunch and subtle texture—it was a hit at a brunch gathering!

Serving & Storage Suggestions

This Moist Lemon Blueberry Layer Cake is best served at room temperature to fully enjoy the creamy buttercream and tender crumb. Slice it up for a brunch, afternoon tea, or a sweet ending to dinner. It pairs beautifully with a cup of Earl Grey tea or a light sparkling wine if you’re celebrating.

Store leftover cake covered tightly in the refrigerator for up to 4 days. If you want to keep it longer, wrap it well in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge before serving.

When reheating, let slices come to room temperature naturally or warm gently in a microwave for 10-15 seconds. The flavors actually deepen after a day or two, so if you can resist, the cake tastes even better the next day!

Nutritional Information & Benefits

This cake offers a decent balance between indulgence and nourishment. Each slice contains approximately 350-400 calories depending on slice size. The fresh lemon zest adds a boost of vitamin C, and blueberries provide antioxidants that support overall health.

Thanks to the buttermilk, the cake has a tender crumb and slight tang, which cuts down on the need for excess sugar. If you swap in almond flour or use vegan ingredients, it can fit gluten-free or dairy-free diets. Just keep in mind the butter and sugar content if you’re watching calories.

From a wellness perspective, this cake feels like a treat you can enjoy without guilt—because it’s homemade, made with real ingredients, and packed with fresh fruit goodness.
