Introduction

This pistachio cake is a moist, nutty delight perfect for any celebration or cozy afternoon treat. With finely ground pistachios folded into the batter and a creamy cream cheese frosting, it balances flavor and texture beautifully.

A three-layer cake with light greenish-yellow sponge textured with small specks, each layer separated and covered by smooth, creamy off-white frosting. The cake's outside is frosted lightly, showing some cake texture through the frosting. The slice is lifted on a metallic spatula, showing the inside clear. The cake is decorated with small clusters of pink flowers and fresh dark blueberries and blackberries placed near the base and on the top. The whole cake sits on a white marble cake stand with a wooden base, set against a clean white marbled background. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 cups (260g) unsalted pistachios (out of shells)
2 and 1/3 cups (275g) cake flour (spooned & leveled)

2 teaspoons baking powder
1/2 teaspoon baking soda

1 teaspoon salt
3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature

1 and 3/4 cups (350g) granulated sugar
5 large egg whites, at room temperature
1/2 cup (120g) sour cream, at room temperature*

2 teaspoons pure vanilla extract
1 teaspoon almond extract
1 cup (240ml) whole milk, at room temperature*

optional: 1 tiny drop green food coloring*
16 ounces (452g) full-fat brick cream cheese, softened to room temperature
1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature

4 cups (480g) confectioners’ sugar
1 and 1/2 teaspoons pure vanilla extract
pinch of salt, to taste

optional: garnishes such as berries and leftover pistachios

Instructions

Step 1: Preheat the oven to 350°F (177°C). Grease three 8-inch round cake pans and line them with parchment paper rounds, then grease the parchment to ensure easy cake release.
Step 2: Pulse the pistachios in a food processor until they become very fine crumbs. Reserve 1 and 1/2 cups (180g) for the cake and keep the rest for garnish.

Step 3: In a large bowl, whisk together the pistachio crumbs, cake flour, baking powder, baking soda, and salt. Set aside.
Step 4: Using a mixer, beat the butter and granulated sugar on high speed until creamy and smooth, about 3 minutes. Scrape down the bowl as needed.
Step 5: Beat in the egg whites on high speed for about 2 minutes, then mix in the sour cream, vanilla extract, and almond extract, scraping the bowl again if necessary.

Step 6: Add the dry ingredients to the wet mixture and start the mixer on low. Slowly pour in the milk (and green food coloring if using) while mixing until just combined. Whisk by hand to break up any lumps; the batter will be slightly thick.
Step 7: Divide the batter evenly among the prepared pans and bake for 21–23 minutes. Check doneness by inserting a toothpick into the center—it should come out clean.
Step 8: Let the cakes cool completely in their pans on a wire rack before frosting.

Step 9: To make the frosting, beat the cream cheese and butter together on medium-high speed until smooth, about 2 minutes.
Step 10: Add the confectioners’ sugar, vanilla extract, and a pinch of salt. Beat on low for 30 seconds, then on high for 3 minutes until creamy. Adjust consistency with more sugar or a little milk if needed.
Step 11: Level the cake layers with a serrated knife. Place one layer on your plate or stand, spread frosting evenly on top, repeat with the second and third layers, then frost the entire cake.

Step 12: Decorate with the reserved pistachios and optional berries. Refrigerate the cake for at least 30 minutes before slicing to help it hold its shape.

Tips & Variations

Roasting the pistachios lightly before pulsing enhances their flavor and aroma.
For a more vibrant color, add a tiny drop of green food coloring to the batter, but it’s optional.

If you don’t have sour cream, you can substitute with plain Greek yogurt at room temperature.
Make sure all dairy ingredients are at room temperature to ensure smooth batter and frosting consistency.

Storage

Store leftover cake tightly covered in the refrigerator for up to 5 days. Before serving, let the cake sit at room temperature for 15–20 minutes for the best texture. You can also freeze the cake layers (unfrosted) wrapped well in plastic wrap and foil for up to 2 months; thaw completely before frosting.

How to Serve

A two-layer round cake covered in smooth white frosting sits on a white plate, placed on a white marbled surface. On top of the cake, there is a decoration of fresh blackberries, blueberries, small pink flowers, and crushed green pistachios, mainly clustered on one side. One slice of the cake is cut and slightly pulled out, revealing a light-colored cake with frosting between the layers. The frosting on the cake has soft swirls and a creamy texture. The photo is bright and clear, showing every detail of the fruit and frosting. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use shelled pistachios instead of unshelled?

Yes, use pistachios that are already shelled and unsalted. This recipe calls for unsalted, out-of-shell pistachios to control the salt and moisture levels in the cake.

Is it necessary to use egg whites only?

Yes, this cake uses only egg whites to help create a light and airy texture. Using whole eggs would change the batter consistency and cake structure.
