Moist Lemon Blueberry Layer Cake Recipe Easy Homemade Creamy Lemon Curd

The first time I baked this Moist Lemon Blueberry Layer Cake with Creamy Lemon Curd, I was honestly just trying to save a weekend that was slipping through my fingers. The day had started off with forgotten grocery lists and a stubbornly non-cooperative oven, and by mid-afternoon, I just wanted a dessert that felt like a small celebration without turning into a complicated ordeal. I spotted a basket of slightly wrinkled blueberries and a lonely lemon on the counter, and on a whim, I decided to turn them into something bright and comforting.

As the cake baked, the kitchen filled with this tangy, sweet aroma that somehow cut through the chaos of the day. When I finally sliced into it, the layers were perfectly moist, and the creamy lemon curd was like a little burst of sunshine in every bite. What surprised me the most was how this cake quickly became the go-to for last-minute guests or when I just needed a slice of something genuinely uplifting. It’s funny how sometimes the simplest ingredients and a pinch of patience can turn a frazzled afternoon around.

What’s stuck with me ever since is the cake’s balance — the way the lemon and blueberries play off each other without one stealing the show, and how the creamy curd adds this luscious texture that feels indulgent but not over the top. It’s a recipe that’s as approachable as it is impressive, and honestly, that’s why it’s found a permanent spot in my baking rotation. If you’re looking for a lemon blueberry cake that’s got real personality and a moist crumb, this one’s got your name on it.

What Ingredients You Will Need

This Moist Lemon Blueberry Layer Cake uses straightforward, wholesome ingredients that come together to create a bright, flavorful dessert without fuss. Most of these are pantry staples, with fresh lemons and blueberries adding that seasonal pop.

• All-purpose flour (2 ½ cups / 320g) – forms the cake’s tender crumb
• Baking powder (2 ½ tsp) – for that perfect rise
• Baking soda (½ tsp) – helps with lift and texture
• Salt (½ tsp) – balances sweetness
• Unsalted butter (1 cup / 227g, softened) – adds richness and moisture (I like using Land O’Lakes for consistency)
• Granulated sugar (1 ¾ cups / 350g) – sweetens without overpowering
• Large eggs (4, room temperature) – for structure and binding
• Buttermilk (1 cup / 240ml, room temperature) – adds tang and tenderness (substitute with milk + 1 tbsp vinegar if needed)
• Fresh lemon juice (¼ cup / 60ml) – real lemon flavor is essential
• Lemon zest (2 tbsp) – packs in bright citrus aroma
• Vanilla extract (1 tsp) – rounds out flavors
• Fresh blueberries (1 ½ cups / 225g) – wash and pat dry, then toss in a little flour to keep them suspended in the batter

For the Creamy Lemon Curd:

• Fresh lemon juice (½ cup / 120ml)
• Lemon zest (1 tbsp)
• Granulated sugar (¾ cup / 150g)
• Unsalted butter (4 tbsp / 56g, softened)
• Large eggs (3, room temperature)
• Salt (a pinch)

You can swap the all-purpose flour for a gluten-free blend if needed, and for a dairy-free option, use coconut yogurt in place of buttermilk, though the texture will shift slightly. The lemon curd can be made ahead and stored in the fridge, which is a real time-saver. For a seasonal twist, try replacing the blueberries with fresh raspberries in summer for a different kind of tart-sweet kick.

Equipment Needed

• Two 8-inch (20 cm) round cake pans – I recommend aluminum pans for even baking; if you only have one, you can bake in batches
• Electric mixer or stand mixer – helps get the butter and sugar fluffy, but a hand mixer works too
• Mixing bowls – a few sizes for wet and dry ingredients
• Zester or microplane – for fresh lemon zest, which really makes the flavor pop
• Whisk – for making the lemon curd smooth
• Spatula – for folding blueberries gently into the batter
• Fine mesh sieve (optional) – useful if you want the lemon curd extra smooth
• Cooling rack – to cool the cakes evenly and avoid sogginess

If you don’t have a stand mixer, a sturdy bowl and a hand mixer will do the job just fine. For the lemon curd, patience is key, so a heavy-bottomed saucepan helps prevent scorching. I’ve tried silicone spatulas and wooden spoons here, and silicone is my favorite for scraping every bit of curd from the pot.

Preparation Method

1. Preheat your oven to 350°F (175°C) and grease the two 8-inch round pans. Line the bottoms with parchment paper for easy removal. This usually takes about 10 minutes.
2. Whisk together the dry ingredients: In a medium bowl, combine 2 ½ cups (320g) of all-purpose flour, 2 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Set aside. This keeps everything evenly distributed and saves mixing time later.
3. Cream the butter and sugar: In a large bowl, using your mixer, beat 1 cup (227g) softened unsalted butter with 1 ¾ cups (350g) granulated sugar until light and fluffy, about 3-5 minutes. This step is crucial for a tender crumb.
4. Add the eggs: Beat in 4 large eggs one at a time, mixing well after each addition. This helps the batter emulsify and rise evenly.
5. Mix in the wet ingredients: Stir in 1 teaspoon vanilla extract, 2 tablespoons fresh lemon zest, and ¼ cup (60ml) fresh lemon juice.
6. Alternate adding dry ingredients and buttermilk: Begin with adding a third of the dry mixture, then half the 1 cup (240ml) buttermilk, repeating until all is incorporated. Mix gently but thoroughly, about 30 seconds after each addition. Overmixing can toughen the cake.
7. Prepare the blueberries: Toss 1 ½ cups (225g) fresh blueberries with a tablespoon of flour from the dry mix. This helps keep them suspended in the batter instead of sinking.
8. Fold blueberries into the batter: Using a spatula, gently fold the blueberries in just until evenly distributed. Avoid overmixing to keep berries intact.
9. Divide batter evenly: Pour the batter into the prepared pans, smoothing the tops with the back of a spoon or spatula. This ensures even baking and uniform layers.
10. Bake: Place pans in the preheated oven and bake for 30-35 minutes. Check doneness by inserting a toothpick in the center—it should come out clean or with a few moist crumbs.
11. Cool: Let cakes cool in pans for 15 minutes before transferring to a wire rack to cool completely. This prevents sogginess and makes frosting easier.
12. Make the lemon curd: While the cakes bake, whisk together ½ cup (120ml) lemon juice, 1 tablespoon lemon zest, ¾ cup (150g) sugar, and a pinch of salt in a saucepan. Beat 3 large eggs in a bowl, then slowly whisk the lemon mixture into the eggs to temper them. Return the mixture to the pan and cook over medium-low heat, stirring constantly, until thickened (about 8-10 minutes). Remove from heat and whisk in 4 tablespoons (56g) softened butter until smooth. Let cool completely; refrigerate if making ahead.
13. Assemble the cake: Place one layer on your serving plate. Spread half of the lemon curd evenly on top. Carefully place the second layer and spread the remaining curd over it. Chill for 30 minutes before slicing to let the curd set slightly.

Pro tip: When folding in blueberries, tossing them in flour really works wonders keeping those juicy bursts scattered throughout the cake instead of disappearing to the bottom. Also, don’t rush the curd—constant stirring and gentle heat make all the difference between a silky finish and scrambled eggs.

Cooking Tips & Techniques

Getting this Moist Lemon Blueberry Layer Cake just right comes down to a few kitchen tricks I’ve picked up over time. First, room temperature ingredients really help the butter and sugar cream evenly, which sets the stage for a tender crumb. Cold eggs or buttermilk can make the batter look curdled or uneven, so plan ahead. You know, sometimes I forget and end up with a slightly lumpy batter, and while it still tastes good, the texture isn’t quite as smooth.

When mixing, avoid over-beating once you add the flour. It’s tempting to get it perfectly smooth, but too much mixing develops gluten, which can make the cake dense. Folding in the blueberries gently rather than stirring vigorously helps keep their shape and color intact.

For the lemon curd, patience is key. Cooking it slowly over low heat and stirring constantly prevents it from scrambling. I’ve learned this the hard way—one batch ended up chunky, which was more like lemon scrambled eggs than curd! If you want extra smooth curd, strain it through a fine mesh sieve after cooking.

Timing-wise, you can make the lemon curd a day ahead, which frees you up on cake day. The cake layers also freeze well individually, so if you want to prep in advance, wrap them tightly in plastic wrap and foil, then thaw before assembling.

Finally, chilling the assembled cake for at least 30 minutes helps the curd set so the slices hold together nicely. I sometimes skip this and regret it—slicing a gooey mess isn’t fun!

Variations & Adaptations

There’s plenty of room to tweak this cake to suit different tastes or dietary needs. Here are a few ideas I’ve tried or thought about:

• Gluten-Free Version: Swap the all-purpose flour for a gluten-free blend like Bob’s Red Mill 1-to-1. It bakes up moist but might be slightly denser.
• Dairy-Free Option: Use coconut yogurt or almond milk with a splash of lemon juice instead of buttermilk. For the butter in the cake and curd, try a plant-based spread like Earth Balance.
• Flavor Boost: Add a teaspoon of poppy seeds to the batter for subtle crunch and a classic lemon-poppy seed combo. I’ve found it adds an interesting texture without overwhelming the blueberries.
• Seasonal Swap: Replace blueberries with fresh raspberries or blackberries in summer for a different berry burst.
• Frosting Twist: Instead of lemon curd, try layering with whipped cream cheese frosting for a richer, tangy finish.

One personal favorite variation was a lemon-blueberry layer cake with almond flour that gave a nuttier crumb and a bit less gluten, perfect for those days I want a slightly different texture. It’s fun to experiment, but honestly, the original recipe’s balance of moist cake and creamy curd keeps pulling me back.

Serving & Storage Suggestions

This cake shines served chilled or at room temperature. I usually take it out of the fridge about 20 minutes before serving so the lemon curd softens slightly, making each slice melt in your mouth. It pairs beautifully with a cup of Earl Grey tea or a light sparkling wine if you’re celebrating.

For storage, keep the cake covered in the fridge for up to 4 days. If you want to keep it longer, the unassembled cake layers freeze well for up to 2 months. Wrap them tightly, then thaw overnight in the fridge before frosting.

When reheating slices, a quick 10-second zap in the microwave can bring back some softness without melting the curd. Flavors tend to deepen after a day, so leftovers (if any!) taste even better the next day.

For a fresh presentation, garnish with a few fresh blueberries and a light dusting of powdered sugar just before serving.
