Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the pistachio cake batter

1 cup (142 g) all-purpose flour
1 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
1 teaspoon matcha powder, optional
3/4 cup (150 g) granulated sugar
1/3 cup (40 g) finely ground roasted salted pistachios, plus extra for decorating
1/4 cup (60 ml) olive oil, or another neutral liquid oil such as sunflower or canola
1 large egg, at room temperature
1/2 cup (120 ml) full-fat plain yogurt
1 tablespoon lemon zest
1/4 cup (60 ml) whole milk, at room temperature
1/2 teaspoon (5 ml) pure vanilla extract
1/4 teaspoon pure almond extract

For the cream cheese frosting

1/2 cup (125 g) very soft cream cheese
2/3 cup (160 ml) heavy whipping cream
4 tablespoons (50 g) granulated sugar
1 teaspoon (5 ml) fresh lemon juice
1/2 teaspoon pure vanilla extract

Ingredient notes

Use roasted pistachios for the best flavor, since roasting deepens their nuttiness and makes the cake more aromatic. Olive oil works especially well here because it complements both the lemon and pistachio, though a neutral oil is also fine if you want a milder taste. The matcha powder is optional, but it helps enhance the natural green tone of the cake and adds a subtle earthy note. Full-fat yogurt adds moisture and a gentle tang that supports the lemon flavor.

Directions

Preheat your oven to 350°F (175°C). Line an 8 x 8-inch square metal baking pan with parchment paper so the cake releases easily after baking.

In a large mixing bowl, sift together the all-purpose flour, baking powder, baking soda, matcha powder if using, and salt. Add the granulated sugar and finely ground pistachios, then whisk until everything is evenly combined.

In a separate medium bowl, whisk together the olive oil, egg, yogurt, lemon zest, whole milk, vanilla extract, and almond extract until the mixture is completely smooth.

Pour the wet ingredients into the bowl of dry ingredients. Gently fold or whisk the batter just until combined, making sure to bring up any dry pockets from the bottom of the bowl. Do not overmix, as this can make the cake less tender.

Spread the batter evenly into the prepared pan. Bake for 20 to 25 minutes, or until the top is lightly golden and a skewer inserted into the center comes out clean.

Let the cake cool in the pan for 20 minutes, then carefully transfer it to a wire rack to cool completely.

To make the frosting, beat the softened cream cheese until smooth. Add 2 tablespoons of the whipping cream and beat again until very smooth and lump-free. Gradually add the remaining cream and continue beating until soft peaks form. Slowly beat in the sugar until the frosting thickens to a spreadable consistency, then mix in the lemon juice and vanilla extract.

Once the cake is fully cooled, spread the frosting evenly over the top. Finish with extra crushed pistachios for garnish, then slice and serve.

Servings and timing

This recipe makes 9 servings.

Prep time: 15 minutes
Cook time: 20 to 25 minutes
Cooling time: about 20 minutes in the pan, plus additional time to cool completely before frosting
Total time: about 1 hour, depending on cooling time

Variations

For a stronger lemon flavor, increase the lemon zest slightly or add a little lemon extract to the batter. This gives the cake a brighter citrus profile without affecting the texture too much.

For a more pronounced pistachio taste, add a few extra tablespoons of finely ground pistachios to the batter or sprinkle a generous layer over the frosting.

You can bake the batter in a 9-inch round pan instead of an 8 x 8-inch square pan if you prefer a round presentation. The quantity of batter remains the same.

To make it a more celebration-style cake, double the recipe and bake it in layers or in a larger pan. A thicker layer of frosting and extra chopped pistachios on top make it especially beautiful for special occasions.

For a slightly different topping, replace the frosting with a lemon mascarpone cream or a lightly sweetened whipped cream if you want an even lighter finish.

Storage/Reheating

Because of the cream cheese frosting, this cake should be stored in the refrigerator. Keep it covered well so it does not dry out, and enjoy it within 5 days for the best texture and flavor.

Before serving, let the cake sit at room temperature for about 15 to 20 minutes so the frosting softens slightly and the cake tastes its best.

This cake is not usually reheated, since it is meant to be served chilled or lightly brought to room temperature. If you want to warm an unfrosted slice slightly, do so very briefly, but avoid heating frosted slices because the topping can melt and lose its texture.

FAQs

Can I make this cake without matcha powder?

Yes. The matcha is optional and mainly helps boost the green color while adding a mild earthy note. The cake will still taste delicious without it.

Can I use unsalted pistachios instead of salted pistachios?

Yes. If using unsalted pistachios, add an extra 1/4 teaspoon of salt to the batter to keep the flavor balanced.

Can I use a different oil instead of olive oil?

Yes. Sunflower, canola, or another neutral liquid oil will work well. Olive oil simply adds a lovely flavor that pairs especially nicely with lemon and pistachio.

Can I bake this in a round cake pan?

Yes. A 9-inch round pan works well for this recipe without changing the ingredient quantities.

Why did my cake turn out dense instead of fluffy?

A dense cake is often caused by overmixing the batter or using cold ingredients that do not blend evenly. Mix only until combined and use room-temperature ingredients whenever possible.

What can I use instead of yogurt?

You can use sour cream as a substitute for the yogurt. It provides a similar richness and tang while helping keep the cake moist.

Can I make this cake ahead of time?

Yes. You can bake the cake a day in advance and frost it once it has fully cooled. Store it covered in the refrigerator until ready to serve.

Can I freeze Lemon Pistachio Cake?

Yes. The unfrosted cake freezes best. Wrap it tightly and freeze for up to 2 months. Thaw it in the refrigerator or at room temperature, then frost before serving.

Can I make this recipe into a layered cake?

Yes. You can double the recipe to make a layered version for a more festive presentation. Be sure to adjust the baking time depending on the pan size you use.

How do I know when the cake is done baking?

The cake is ready when the top springs back lightly when touched and a skewer inserted into the center comes out clean or with just a few moist crumbs.

Lemon Pistachio Cake is the kind of recipe that feels both simple and elegant at the same time.
