This is a butter cake built around finely ground pistachios and cardamom — two ingredients that do real work here, adding nuttiness, fragrance, and a faint green tint to the crumb. It bakes in a single 9-inch round, takes about 30 minutes of hands-on time, and holds up well over a couple of days, which makes it genuinely useful when you’re planning ahead for a gathering or holiday table.
The short version of why this works
Two things matter most in this recipe. First, the alternating flour-and-milk method: adding the dry ingredients and milk in stages keeps the batter from breaking and produces a fine, even crumb rather than a dense or gummy one. Second, grinding the pistachios finely before folding them in — not stirring them in early — means they stay distributed throughout the batter without sinking, and their fat contributes moisture without weighing the cake down. Skip either step and the texture suffers noticeably.
Troubleshooting
- Cake sinks in the center: The oven was opened too early, or the batter was overmixed after the flour went in. Wait until at least the 45-minute mark before checking, and mix only until the flour disappears.
- Pistachios clump together in the batter: They weren’t ground finely enough, or they were still slightly warm from the food processor. Let them cool completely and pulse until the texture resembles coarse almond flour before folding in.
- Cardamom flavor is barely detectable after baking: Pre-ground cardamom loses potency quickly. If yours has been open for more than a few months, use 2½ teaspoons instead of 2, or grind whole green cardamom seeds fresh — the difference is significant.
- Cake sticks to the pan despite greasing and flouring: Line the bottom with a parchment round in addition to greasing and flouring the sides. Nut-based batters can bond to the pan more stubbornly than plain flour batters.
- Top browns too fast before the center is set: Tent the pan loosely with foil at the 35-minute mark. This is more common in ovens that run hot — worth doing if your oven has a history of over-browning cakes.
Storage and make-ahead
The baked cake keeps at room temperature, tightly wrapped, for up to 2 days — and honestly tastes better on day two once the cardamom has had time to settle into the crumb. For longer storage, wrap the fully cooled cake in plastic wrap and then foil and freeze for up to 2 months; thaw overnight at room temperature still wrapped. If you’re baking for an event, you can also freeze the undecorated cake layers up to a week out, which takes the pressure off the day before. Skip the garnish — not worth the extra dish — and let the cake stand on its own or add a simple dusting of powdered sugar right before serving.
Pistachio Cardamom Cake
Equipment
- Mixing Bowl
- Electric Mixer
- 9-inch round cake pan
- Spatula
- wire rack
Ingredients
- 1 cup unsalted butter room temperature
- 1 ½ cups granulated sugar
- 4 large eggs room temperature
- 2 cups all-purpose flour sifted
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup pistachios finely ground
- 1 cup whole milk room temperature
- 1 teaspoon pure vanilla extract
- 2 teaspoons ground cardamom
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
- In a large mixing bowl, beat the butter and sugar with an electric mixer on medium speed until light and fluffy, about 3-4 minutes.
- Add the eggs one at a time, beating well after each addition, to ensure a smooth batter.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add to the creamed mixture alternately with the milk, beginning and ending with the flour mixture. Mix just until combined to avoid overworking the batter.
- Fold in the ground pistachios, vanilla extract, and ground cardamom until evenly distributed. The batter should be silky and fragrant.
- Pour the batter into the prepared cake pan, smoothing the top with a spatula.
- Bake in the preheated oven for 50-55 minutes, or until a toothpick inserted into the center comes out clean. Let cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.
Notes
- Try adding a touch of lemon zest for an extra burst of freshness.
- Use freshly ground cardamom for the most vibrant flavor.

Common questions
Can I use salted pistachios instead of unsalted?
It’s better to use unsalted. Salted pistachios will push the total sodium up noticeably and can make the sweetness taste off-balance, especially since the recipe already includes half a teaspoon of salt.
Can I make this as a loaf cake instead of a round?
Yes, a standard 9×5-inch loaf pan works. Start checking for doneness at 55 minutes, but it may need up to 65 minutes — the narrower shape takes longer to bake through at the center.
Do the eggs and butter really need to be at room temperature?
Yes, and it matters more here than in many recipes. Cold butter won’t cream properly with the sugar, and cold eggs can cause the batter to curdle, which leads to a denser, uneven crumb. Pull them out about an hour before you start.
