- Butter – Essential for richness and creating a tender texture in the cake.
- Granulated Sugar – This sweetens the cake while aiding in achieving the right texture.

Step‑by‑Step Instructions for Lemon Pistachio Cake with Mascarpone Frosting
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and prepare an 8×8-inch baking pan by greasing it with butter. Line the bottom with parchment paper to ensure easy removal of your moist lemon pistachio cake later. This step is crucial for achieving a beautifully baked cake that won’t stick.
Step 2: Combine Dry Ingredients
In a food processor, finely grind the pistachios and lemon zest until they’re almost powdered. Combine this mixture with cake flour, baking powder, and baking soda in a large mixing bowl. This careful blending infuses the dry ingredients with bright, nutty flavors, setting the stage for your delightful cake.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together the sour cream, vanilla extract, and milk until smooth and well-incorporated. The creamy mixture will add moisture and richness to the lemon pistachio cake. Make sure the ingredients are at room temperature for the best texture and consistent blending with the rest of the batter.
Step 4: Cream Butter and Sugar
Using a stand mixer, cream together the softened butter, granulated sugar, and a pinch of salt at medium speed for about 3 minutes. You’re aiming for a light and fluffy texture that should resemble whipped cream. This fluffy base is essential for giving your cake that perfect tender crumb.
Step 5: Incorporate the Eggs
Add the eggs, one at a time, mixing well after each addition until fully combined. Scrape down the sides of the mixing bowl as needed to ensure even mixing. This step not only provides structure but also helps the cake rise beautifully while blending the rich flavors together.
Step 6: Alternating Dry and Wet Mixtures
Gradually incorporate the dry ingredients and the wet mixture alternately into the butter mixture, starting and finishing with the dry ingredients. Stir gently until just combined to maintain the light texture of the lemon pistachio cake. Over-mixing can lead to a dense cake, so be gentle!
Step 7: Bake the Cake
Pour the batter into your prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 35-40 minutes, or until the cake springs back when gently pressed and a toothpick inserted in the center comes out clean. Let it cool in the pan for 10 minutes before transferring it to a wire rack.
Step 8: Prepare the Frosting
In a mixing bowl, combine the mascarpone cheese, sifted powdered sugar, and fresh lemon juice. Beat the mixture on low speed until just smooth, being careful not to over-mix, which can make it too soft. This creamy frosting will enhance the flavor of your lemon pistachio cake beautifully.
Step 9: Frost the Cake
Once the cake has completely cooled, spread a generous layer of the mascarpone frosting over the top using a spatula. For an extra touch, sprinkle chopped pistachios on top of the frosting for added crunch and visual appeal. This step is where the magic truly happens as you transform your cake into a delightful dessert.

Expert Tips for Lemon Pistachio Cake
- Egg Temperature: Use room temperature eggs for the best results; cold eggs can lead to a dense cake.
- Avoid Overmixing: Mix the batter gently; over-mixing can make the lemon pistachio cake dense instead of light and fluffy.
- Cream Cheese Option: If you substitute cream cheese for mascarpone, use a little less sugar for better flavor balance.
- Pistachio Processing: Be cautious not to grind the pistachios into a paste; aim for a fine, crumbly texture for that perfect crunch.
- Cooling Time: Allow the cake to cool completely before frosting; this prevents the mascarpone frosting from melting into a puddle.

Lemon Pistachio Cake with Mascarpone Frosting Recipe FAQs
What type of lemons should I use for this cake?
Absolutely, using fresh, ripe lemons is key to achieving the best flavor. Look for lemons that are vibrant yellow and feel heavy for their size, indicating juiciness. Avoid any that have dark spots or are overly soft, as this may mean they’re past their prime.
