Lemon Pistachio Cake Ingredients
For the Cake
- All-Purpose Flour – Forms the cake’s structure; can be substituted with a gluten-free flour blend for a different texture.
- Cornstarch – Softens the cake texture; for a substitute, use the equivalent amount of all-purpose flour.
- Pistachios – Adds nuttiness and flavor; unsalted or lightly salted can both work beautifully.
- Baking Powder & Baking Soda – Essential leavening agents to achieve that perfect rise.
- Salt – Enhances the overall flavor; use kosher or sea salt for best results.
- Unsalted Butter – Provides richness and moisture; can be swapped with oil for a lighter texture.
- Granulated Sugar – Sweetens the cake; brown sugar can add a deeper flavor.
- Eggs – Bind ingredients and create structure; for a vegan option, consider using flax eggs.
- Sour Cream – Adds moisture and tang; Greek yogurt can substitute perfectly.
- Vanilla Extract – Enhances depth of flavor; almond extract could be an alternative.
- Milk – Moistens the batter; any non-dairy milk can be used for a vegan choice.
- Lemon Zest & Juice – Brightens flavor; fresh is irreplaceable, so don’t skimp on this key ingredient.
For the Frosting
- Mascarpone Cheese – Creates a creamy frosting; cream cheese can be used for a different tanginess.
- Powdered Sugar – Sweetens the frosting and adds a silky texture; sift before use for a smoother mix.
- Vanilla Extract – Adds another layer of flavor; a splash goes a long way in balancing the tartness of the lemon.

Step‑by‑Step Instructions for Lemon Pistachio Cake with Mascarpone Frosting
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan with unsalted butter and line the bottom with parchment paper for easy removal. This step ensures that your lemon pistachio cake bakes evenly and releases smoothly once it’s done.
Step 2: Process the Pistachios
In a food processor, pulse the pistachios and lemon zest together until they reach a fine consistency. Once ground, transfer this mixture into a large mixing bowl. To this bowl, add all-purpose flour, baking powder, baking soda, and salt, whisking them together to combine. The nutty aroma should fill your kitchen as the cake’s foundation comes together.
Step 3: Mix the Wet Ingredients
In a separate bowl, whisk together the sour cream, milk, and vanilla extract until smooth and well-blended. This creamy mixture adds moisture and richness to your lemon pistachio cake. Set it aside so that it can be incorporated into the batter later.
Step 4: Cream the Butter and Sugar
Using a stand mixer, cream the unsalted butter and granulated sugar together on medium speed until the mixture is light and fluffy, about 3-4 minutes. This step is crucial as it creates air pockets that will help the cake rise beautifully. Once fluffy, add the eggs one at a time, ensuring each is fully incorporated before adding the next.
Step 5: Combine Dry and Wet Ingredients
Gradually mix the dry ingredients into the creamed butter mixture, alternating with the wet ingredients. Begin and end with the dry ingredients, mixing on low speed until just combined. Overmixing can lead to a dense cake, so stop as soon as the flour is absorbed. The batter should appear thick yet smooth with hints of green from the pistachios.
Step 6: Bake Your Cake
Pour the batter into the prepared baking pan, using a spatula to smooth the top for an even bake. Place it in the preheated oven and let it bake for 35-40 minutes. Check for doneness by inserting a toothpick in the center; it should come out clean. The top should be a light golden-brown, signaling the cake is ready.
Step 7: Cool and Transfer
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, carefully transfer it to a wire rack to cool completely. This step is essential, as it allows the cake to set properly before adding the luscious mascarpone frosting.
Step 8: Prepare the Mascarpone Frosting
In a large bowl, combine the mascarpone cheese and powdered sugar, mixing until smooth and creamy. Add a splash of vanilla extract to enhance the flavor, and continue mixing until the frosting is fluffy. This creamy goodness will beautifully spread over your cooled lemon pistachio cake.
Step 9: Frost and Serve
Once the cake has cooled completely, spread the mascarpone frosting evenly over the surface. For a decorative touch, sprinkle additional chopped pistachios on top. Slice the cake and serve it to your family and friends, celebrating the delightful flavors of this lemon pistachio cake with mascarpone frosting in each bite.

Expert Tips for Lemon Pistachio Cake
-
Room Temperature Ingredients: Ensure all ingredients, especially butter and eggs, are at room temperature for a smooth batter, resulting in a tender lemon pistachio cake with mascarpone frosting.

Salt Moderation: If using salted pistachios, reduce the added salt in the recipe to prevent the cake from becoming overly salty.

Make Ahead Options
This Lemon Pistachio Cake with Mascarpone Frosting is a fantastic choice for meal prep, making your baking adventures easier! You can prepare the cake itself up to 24 hours in advance. After baking and cooling, wrap it tightly in plastic wrap and refrigerate to maintain its freshness. For optimal quality, frost the cake just before serving; if you want to add the frosting early, store the frosted cake in the refrigerator and let it sit at room temperature for 30 minutes before serving so the mascarpone frosting regains its creamy texture.

Lemon Pistachio Cake with Mascarpone Frosting Recipe FAQs
How do I choose the right pistachios for the cake?
Absolutely! When selecting pistachios for your Lemon Pistachio Cake, opt for unsalted or lightly salted nuts. Look for those that are bright green in color; avoid any with dark spots or a stale smell. Freshness is key to ensuring vibrant flavor in your cake!
What’s the best way to store leftovers?
You can store your Lemon Pistachio Cake in the refrigerator for up to 3 days. It’s best to keep it covered in plastic wrap or in an airtight container to maintain its moisture. If you plan on keeping it longer, I recommend not frosting it until you’re ready to serve, as this will preserve its texture even better.
Can I freeze Lemon Pistachio Cake, and how should I do it?
Yes! You can freeze the un-frosted cake for up to 2 months. To do this, wrap the cooled cake tightly in plastic wrap and then in aluminum foil to prevent freezer burn. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight, and then frost it with your luscious mascarpone frosting!
What if my cake comes out too dense or flat?
Very! If your Lemon Pistachio Cake is too dense, it might be due to overmixing the batter or not incorporating enough air during the creaming stage. To ensure a light and airy cake, mix the ingredients just until combined. If it comes out flat, check that your baking powder is fresh before use, as expired leavening agents can affect rising.
Are there any dietary considerations for this cake?
If you’re catering to dietary restrictions, you can indeed modify this recipe! For a vegan version, substitute eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water equals one egg) and use a non-dairy milk. For nut allergies, you could try using sunflower seeds instead of pistachios, though the texture and taste will vary slightly. Always check for any individual ingredient allergies before serving!
