There is a reason I keep coming back to this Lemon Pistachio Cake. It delivers something few cakes do. You get sharp citrus cutting through rich pistachio, with every layer balanced like I intended it to be from the start.
You will walk away from this recipe with a cake that feels both elegant and comforting. It works beautifully for celebrations, birthdays, or any day when an average cake just won’t do. This article will guide you step by step, with the same notes I’ve recorded in my kitchen journal after making this dozens of times.
I will show you how to handle the alternating layers, how to keep the mascarpone frosting stable, and how to achieve that polished pistachio finish. You will build confidence with every stage.
Why This Lemon Pistachio Cake Stands Out
Most pistachio cakes lean heavy, with a dense, monotone flavor. I approach it differently.
The alternating layers of lemon cake and pistachio cake create contrast both in flavor and appearance. The citrus brightens the nutty base, preventing it from becoming heavy.
The homemade lemon curd adds freshness, while the mascarpone frosting brings a creamy softness without overwhelming sweetness.
This cake holds structure beautifully, slices cleanly, and offers a bakery-style presentation right from your home kitchen.
Ingredient Notes: Build the Right Flavors from the Start
The lemon layers rely on fresh lemon juice and zest. I never substitute bottled juice. The zest carries most of the flavor. You need both for balance.
The pistachio layers call for finely ground unsalted pistachios. In my experience, grinding them too fine creates a paste that clumps in the batter. I pulse them carefully in a food processor until sandy but still dry.
For the frosting, mascarpone performs better than cream cheese here. It stays light and smooth, while still adding richness. Heavy cream gives it body without making it too sweet.
Comparison: Buttermilk vs Whole Milk
I’ve tested both buttermilk and whole milk across the layers. Buttermilk belongs in the lemon layers. It softens the crumb and reacts with the baking soda to create tenderness while enhancing the citrus notes.
Whole milk supports the pistachio layers better. The fat preserves the nut flavor and helps the crumb remain sturdy, so the stack holds its height without collapsing.
If you swap the two, you risk flattening the lemon layers or muting the pistachio.
Mixing the Lemon Cake Batter
Start by creaming the butter and sugar together until light. This creates structure and traps air, which translates to a finer crumb.
Add the eggs one at a time to maintain emulsion. Once combined, fold in the lemon zest, juice, and vanilla.
The dry ingredients and buttermilk go in alternately. This keeps the batter stable and prevents curdling.
Divide evenly into prepared pans, smoothing the tops for even baking.
Mixing the Pistachio Cake Batter
Cream the butter and sugar until fluffy. This base needs more air to handle the weight of ground pistachios.
Beat in the eggs one at a time, followed by the almond extract. The almond boosts the pistachio notes without overwhelming them.
Fold in the dry ingredients alternately with whole milk. Avoid overmixing to preserve tenderness.
Spread into prepared pans and tap gently to release air pockets.
Preparing the Lemon Curd
Lemon curd can intimidate, but the process is simple with steady attention.
Whisk together lemon juice, zest, sugar, and egg yolks over medium heat. Keep stirring constantly.
The mixture will thicken after several minutes. You will see it coat the back of a spoon.
Remove from heat and stir in cold butter cubes. They finish the texture and cool the curd slightly.
Refrigerate until firm. I often make this the day before.
Whipping the Mascarpone Frosting
Beat mascarpone and powdered sugar together first. This ensures a smooth base before adding cream.
Slowly add cold heavy cream and vanilla extract. Whip until thick but stop before it stiffens too much. Overwhipping risks breaking the mixture.
If you see soft, spreadable peaks, you are done. Refrigerate if you need to hold it before assembling.
Assembling the Lemon Pistachio Cake
Level each layer to create flat surfaces. Stacking uneven layers leads to slipping.
Begin with a pistachio layer on your serving board. Spread a thin coat of mascarpone frosting, followed by a spoonful of lemon curd. Spread gently to avoid mixing layers.
Alternate lemon and pistachio layers, repeating the frosting and curd in between.
After stacking, apply a thin crumb coat of frosting. Chill for 30 minutes to firm up before adding the final smooth layer.
Press crushed pistachios along the bottom edge for visual contrast. Add lemon zest curls for a fresh accent on top.
Serving and Storage Advice
This cake cuts cleanly after chilling for at least one hour.
I prefer serving it slightly chilled. The flavors stay defined, and the mascarpone holds its structure.
Leftovers store well in the refrigerator for up to three days. Wrap slices tightly to prevent the curd from drying out.
The cake layers may be baked one day in advance. Cool completely and wrap well before stacking.

Ingredients
- FOR THE LEMON CAKE LAYERS (2 LAYERS)
- 1 ¾ cups all-purpose flour

- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs
- 1 tablespoon lemon zest (about 2 lemons)
- ½ cup buttermilk
- ¼ cup fresh lemon juice
- 1 teaspoon vanilla extract
- FOR THE PISTACHIO CAKE LAYERS (2 LAYERS)
- 1 ½ cups all-purpose flour
- 1 ½ teaspoons baking powder
- ¼ teaspoon salt
- ½ cup shelled unsalted pistachios, finely ground
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs
- 1 teaspoon almond extract
- ½ cup whole milk
- FOR THE LEMON CURD FILLING
- ½ cup fresh lemon juice
- 1 tablespoon lemon zest
- ½ cup granulated sugar
- 3 egg yolks
- ¼ cup unsalted butter, cubed
- FOR THE MASCARPONE FROSTING
- 1 cup cold heavy whipping cream
- 8 ounces mascarpone cheese
- ½ cup powdered sugar
- 1 teaspoon vanilla extract
Instructions
- MAKE THE LEMON CAKE LAYERS: Preheat oven to 350°F (175°C). Grease and line two 6-inch round cake pans with parchment paper. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. In a separate large bowl, beat the butter and sugar until light and fluffy, about 3 minutes. Add eggs one at a time, mixing well after each. Stir in lemon zest, lemon juice, and vanilla. Add the dry ingredients in three additions, alternating with buttermilk, beginning and ending with the dry. Divide the batter evenly between the prepared pans and bake for 25 to 28 minutes or until a toothpick inserted in the center comes out clean. Cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
- MAKE THE PISTACHIO CAKE LAYERS: Preheat oven to 350°F if not already on. Grease and line two 6-inch round pans. In a medium bowl, whisk together the flour, baking powder, salt, and finely ground pistachios. In a separate bowl, beat the butter and sugar until fluffy, about 2 to 3 minutes. Add eggs one at a time, then stir in the almond extract. Mix in the dry ingredients in three additions, alternating with the milk. Pour the batter evenly into the pans and bake for 25 to 28 minutes. Let cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
- MAKE THE LEMON CURD: In a medium saucepan, combine the lemon juice, zest, sugar, and egg yolks. Whisk together over medium heat. Cook, stirring constantly, until the mixture thickens and coats the back of a spoon, about 7 to 8 minutes. Remove from heat and stir in the cubed butter until fully melted and smooth. Transfer to a jar or bowl and refrigerate until set, at least 1 hour.
- MAKE THE MASCARPONE FROSTING: In a large bowl, beat the mascarpone and powdered sugar until smooth. Add the heavy cream and vanilla extract, then whip on medium-high speed until thick and spreadable, being careful not to overbeat.
- ASSEMBLE THE CAKE: Trim the tops of all cake layers to level them. Place one pistachio cake layer on a serving plate or cake board. Spread a thin layer of mascarpone frosting over the top, then spoon a small amount of lemon curd over the frosting. Repeat with one lemon cake layer, frosting, and curd. Continue alternating layers until all four are stacked, ending with a lemon layer on top. Apply a thin crumb coat of frosting to seal in crumbs and chill the cake for 30 minutes. After chilling, apply the final layer of mascarpone frosting. Press crushed pistachios around the bottom edge and garnish the top with lemon zest curls if desired.
Notes
For best texture, grind pistachios finely but avoid turning them into a paste. Chill the assembled cake for at least 1 hour before slicing for cleaner cuts. Cake layers can be baked up to one day in advance and stored tightly wrapped at room temperature.
