Step‑by‑Step Instructions for lemon pistachio cake with mascarpone frosting
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it heats up, take an 8×8-inch baking pan, butter it generously, and line it with parchment paper for easy removal after baking. Ensure the parchment overlaps the edges for a simple lift-out method.
Step 2: Prepare the Dry Ingredients
In your food processor, pulse the pistachios and lemon zest until finely ground. In a medium bowl, whisk together this mixture with cake flour, baking powder, and baking soda. Set these dry ingredients aside, as they will blend harmoniously with the wet mixtures in your lemon pistachio cake.
Step 3: Mix the Wet Ingredients
In a separate mixing bowl, combine the sour cream, whole milk, and vanilla extract. Whisk these ingredients together until smooth, allowing the mixture to blend completely. Having your wet ingredients ready makes it easier to alternate them with the dry ingredients later on.
Step 4: Cream the Butter and Sugar
Using a stand mixer, cream the room temperature unsalted butter and granulated sugar together until the mixture is light and fluffy, about 3 minutes. Pause to scrape down the sides of the bowl as needed. Then, add the eggs one at a time, ensuring each is well incorporated before adding the next, creating a rich foundation for your lemon pistachio cake.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the creamed butter mixture, alternating with the wet ingredients. Start and end with the dry ingredients, mixing gently until just combined. Watching for lumps is key; overmixing can lead to a dense cake. Aim for a smooth batter that’s vibrant and inviting!
Step 6: Bake the Cake
Carefully pour the batter into your prepared pan, smoothing the top with a spatula. Place it in the preheated oven and bake for 35–40 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean, signaling a beautifully risen lemon pistachio cake.
Step 7: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, gently transfer it to a wire rack to cool completely. This step is crucial to avoid a soggy base, ensuring that the texture remains light and fluffy.
Step 8: Prepare the Mascarpone Frosting
As the cake cools, you can whip up the mascarpone frosting. In a mixing bowl, blend mascarpone cheese, powdered sugar, vanilla extract, and lemon zest until smooth but avoid over-mixing. The frosting should have a luscious texture, ready to enhance the cake with its creamy delight.
Step 9: Frost the Cake
Once the lemon pistachio cake has cooled completely, spread the mascarpone frosting evenly over the top using a spatula. Be generous—this frosting is the pièce de résistance! Finish by sprinkling chopped pistachios for that perfect crunchy garnish, adding extra flavor and visual appeal.
Step 10: Serve and Enjoy
Slice your delightful lemon pistachio cake with mascarpone frosting and serve at room temperature. Ideal for celebrations or a special afternoon treat, this cake pairs beautifully with herbal tea or sparkling lemonade. Indulge yourself and your guests in this zesty and creamy creation!

Lemon Pistachio Cake with Mascarpone Frosting Recipe FAQs
What type of pistachios should I use for the cake?
Absolutely! I recommend using shelled, unsalted pistachios for your lemon pistachio cake with mascarpone frosting. If you prefer a more pronounced flavor, feel free to use lightly salted pistachios as well. Just remember to adjust the overall salt in the recipe accordingly for balance.
How long can I store the cake, and what’s the best method?
You can store your frosted lemon pistachio cake in an airtight container in the refrigerator for up to 3 days. Make sure to cover it well so it stays moist and delicious. If it’s unfrosted, it can sit at room temperature in an airtight container for up to 2 days.
Can I freeze the cake, and how should I do it?
Absolutely! To freeze the unfrosted lemon pistachio cake, wrap it tightly in plastic wrap and then in aluminum foil to shield it from freezer burn. It will keep well for up to 2 months. When ready to enjoy, thaw it in the refrigerator overnight and allow it to come to room temperature before frosting.
What if my batter is too thick or too thin?
Very! If you find your batter is too thick after mixing, you can add a tablespoon of milk at a time until you reach the desired consistency. Conversely, if it’s too thin, mix in a little more cake flour (be cautious; a tablespoon at a time). It’s important to get a nice, smooth texture to ensure a light and fluffy cake.
Can I make this cake vegan or gluten-free?
Certainly! To make a vegan version, substitute eggs with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water for each egg) and use plant-based milk and dairy-free butter. For a gluten-free alternative, replace cake flour with a gluten-free blend or use 1 ¾ cups of a gluten-free flour mix combined with ¼ cup of cornstarch. Just ensure your other ingredients, like baking powder, are also gluten-free!
