Step‑by‑Step Instructions for Lemon Pistachio Cake with Mascarpone Frosting
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). While it warms up, take an 8×8-inch baking pan, generously butter it, and line the bottom with parchment paper. This ensures your cake releases easily after baking and helps maintain its beautiful shape.
Step 2: Mix Dry Ingredients
In a food processor, pulse together the pistachios and lemon zest until finely ground. In a separate mixing bowl, whisk together the cake flour, baking powder, and baking soda. This aromatic mixture will be the foundation of your cake, providing a tender crumb and delightful flavor.
Step 3: Combine Wet Ingredients
In another bowl, whisk together the sour cream, milk, and vanilla extract until smooth and well combined. This creamy mixture adds moisture and richness to the lemon pistachio cake, enhancing its overall taste and texture as you prepare to blend it with your dry ingredients.
Step 4: Cream Butter and Sugar
Using a stand mixer, beat the softened butter, granulated sugar, and salt together on medium speed until the mixture is light and fluffy, about 3 minutes. This step creates air pockets in the batter, ensuring your cake is airy and has that perfect springy texture everyone loves.
Step 5: Incorporate Eggs
Next, add the eggs one at a time to the butter mixture, mixing well after each addition. This helps to fully integrate the eggs, providing the structure necessary for your lemon pistachio cake. You’ll notice the batter becoming smooth and creamy as you mix.
Step 6: Combine Mixtures
With the mixer on low speed, gradually add the dry ingredients to the butter-egg mixture, alternating with the wet ingredients. Start and end with the dry ingredients, mixing just until combined. This careful blending ensures your batter maintains the perfect consistency for a light, fluffy cake.
Step 7: Bake the Cake
Gently pour the batter into the prepared pan, smoothing the top with a spatula. Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean. The cake should be golden and slightly springy to the touch, signaling it’s ready to come out.
Step 8: Frost and Serve
Allow your lemon pistachio cake to cool in the pan for about 10 minutes, then carefully transfer it to a wire rack to cool completely. Once cooled, generously spread the luscious mascarpone frosting on top, and sprinkle with chopped pistachios for an added crunch and beautiful presentation before serving.

Expert Tips for Lemon Pistachio Cake
-
Mixing Matters: Avoid overmixing the batter; this can lead to a dense cake rather than the fluffy texture you desire in your lemon pistachio cake with mascarpone frosting.
-
Room Temperature Ingredients: Ensure your butter, eggs, and sour cream are at room temperature before mixing. This promotes better emulsification and results in a smoother batter.
-
Toothpick Test: When checking for doneness, a toothpick should come out clean, but a few moist crumbs are okay. This indicates that your cake is perfectly cooked and not dry.
-
Frosting Consistency: If your mascarpone frosting is too runny, add more powdered sugar to thicken it. Conversely, if it’s too thick, blend in a splash of heavy cream to reach the desired spreadable consistency.
-
Storage Tips: Store unfrosted cake at room temperature for up to 3 days, but once it’s frosted, keep it in the fridge to maintain freshness.
Lemon Pistachio Cake with Mascarpone Frosting Recipe FAQs
How do I select ripe lemons for this cake?
Absolutely! When choosing lemons, look for ones that are firm and slightly heavy for their size. The skin should be bright yellow and relatively smooth, ensuring juiciness. Avoid lemons with dark spots or wrinkles, as these may be overripe or dried out.
What is the best way to store the frosted cake?
Store your Lemon Pistachio Cake with Mascarpone Frosting in the refrigerator to keep it fresh. Put it in an airtight container, and it will remain delicious for up to 3 days. If you need to serve it later, allow it to sit at room temperature for about 30 minutes before enjoying for the best flavor.
Can I freeze the unfrosted cake?
Absolutely! To freeze your Lemon Pistachio Cake, wrap it tightly in plastic wrap, then place it in a sturdy freezer bag or wrap it in aluminum foil. It can be safely frozen for up to 2 months. To thaw, simply transfer it to the refrigerator overnight, and once defrosted, you can frost it with your mascarpone frosting.
What should I do if my batter is too thick?
If you find your batter is too thick, don’t worry! Add a tablespoon of milk at a time until you reach the desired consistency. Remember, you want a batter that gently falls from the spatula without being overly runny. Just be careful not to overmix, as this can affect the cake’s fluffiness.
Are there any dietary considerations for this recipe?
Very! This cake is not gluten-free, as it uses cake flour. If you have gluten allergies, consider using a gluten-free flour blend that’s designed for baking. Additionally, if you’re making it for someone with nut allergies, you can omit the pistachios and increase the lemon zest for that signature zesty flavor. Always ensure to check ingredient labels to avoid cross-contamination.
