This moist Pistachio Bundt Cake is made with roasted pistachios, pistachio paste, and almond meal for plenty of real pistachio flavor. Sour cream keeps the crumb soft and moist, and a thick vanilla glaze finishes the cake beautifully.

Pistachio feels like it’s everywhere lately, which is funny because I don’t remember it being nearly this popular when I was growing up. I’m not complaining, though!

Pistachio can be a surprisingly hard flavor to carry through an entire cake. A handful of chopped nuts adds texture, but not necessarily enough flavor to make the whole cake taste distinctly like pistachio.

This Pistachio Bundt Cake solves that problem by using pistachios three ways: ground roasted pistachios in the batter, pistachio paste for concentrated flavor, and chopped pistachios on top.

And yes, that’s a lot of pistachio. That’s the point.

Sour cream and almond flour keep the crumb soft and moist, while a little lemon zest adds just enough brightness to balance all those rich, nutty flavors.

Finish it with a thick glaze and even more chopped pistachios, and you have a cake that tastes unmistakably like pistachio from the first bite to the last.

Because if pistachio is in the name, you shouldn’t have to go looking for it.

Ingredients and Substitutions

The key to a really good pistachio cake is getting enough pistachio flavor without making the crumb heavy or greasy. Pictured below are all the ingredients used to make the cake, with a few notes on the most important ones

Pistachios

Use roasted, unsalted pistachios for the strongest flavor without adding extra salt to the cake. The pistachios are finely ground into the batter, with more chopped pistachios added on top.

Pistachio Paste

Pistachio paste is just very finely ground pistachios, but it behaves differently from the pistachios ground for the batter. The ground nuts add texture and little bits of pistachio throughout the crumb, while the paste distributes more evenly and gives the cake a stronger, more concentrated pistachio flavor. Look for pistachio paste made from 100% pistachios. Avoid sweetened pistachio cream, which contains additional sugar and fat and has a much milder pistachio flavor.

Flour

All-purpose flour provides the structure for this rich, nut-heavy cake. A 1:1 gluten-free baking flour works as a substitute to make a gluten-free pistachio bundt cake.

Almond Meal

Almond meal adds extra fat and helps keep the crumb soft and tender. You can also use finely ground almond flour; the cake may have a slightly lighter color and finer crumb.

Sour Cream

Full-fat sour cream adds moisture and richness without thinning the batter too much. Full-fat plain Greek yogurt is the best substitute.

How to Make Pistachio Bundt Cake

This is an easy cake to make, but there are a few details that make a big difference in the final texture. Most importantly, don’t overprocess the pistachios and give the butter and sugar enough time to cream properly.

Grind the Pistachios

Add the pistachios and a small amount of the flour to a food processor, then pulse until the nuts are finely ground and resemble coarse sand. The flour helps absorb some of the oils released by the pistachios, making it less likely that they’ll turn into pistachio butter.

Make the Batter

Beat the butter and sugar together for 3 to 4 minutes, until pale and fluffy. Beat in the eggs one at a time, followed by the sour cream, milk, vanilla, pistachio paste, and lemon zest. The mixture may look curdled or slightly separated once all the liquid is added. That’s normal and will resolve once the dry ingredients are mixed in.

Add Dry Ingredients

Add the dry ingredients and mix on low speed just until no streaks of flour remain. The batter will be quite thick. Stop mixing as soon as everything comes together to avoid developing too much gluten.

Bake the Bundt Cake

Transfer the batter to a thoroughly greased and floured Bundt pan and smooth the top. Bake until a tester inserted into the center comes out clean or with a few moist crumbs. If the top starts to brown too quickly, loosely tent the pan with foil. Let the cake cool in the pan for 15 minutes before inverting it onto a wire rack to cool completely.

Glaze the Cake

Whisk the powdered sugar with 1½ tablespoons of milk until smooth. Add more milk, 1 teaspoon at a time, until the glaze is thick but pourable. Drizzle the glaze over the completely cooled cake, then finish with chopped pistachios.

Ground Pistachios Keep the Crumb Tender

Pistachios do more here than add flavor. Grinding them into the batter changes the texture of the cake, too, giving it a softer, richer crumb than flour alone would provide.

But there is a balance. Too much nut flour can make a cake dense or fragile, because nuts don’t build structure the way wheat flour does. This recipe uses all-purpose flour, almond flour, and ground pistachios together so each one can do a different job.

Kitchen Chemistry

Ground pistachios and almond flour dilute the gluten-forming proteins in the all-purpose flour while adding fat that coats flour particles and interferes with gluten development. That weakens the gluten network enough to keep the crumb tender, while the wheat flour still provides enough structure to trap expanding gases from the leavening.

The ground nuts also contribute their own oils, which help the cake stay soft after baking. The result is a crumb that feels rich and moist without becoming heavy or falling apart.

Frequently Asked Questions

Can I use raw pistachios instead of roasted pistachios?

Yes, but roasted pistachios will give the cake a deeper, more noticeable pistachio flavor. If you only have raw pistachios, toast them lightly and let them cool completely before grinding.

Can I make this cake gluten-free?

A 1:1 gluten-free baking flour will work in place of the all-purpose flour. Use a blend designed as a direct wheat-flour replacement, and keep the almond flour and ground pistachios as written. Ensure all other ingredients are certified gluten-free.

Why does the batter look curdled after I add the wet ingredients?

The batter contains a large amount of dairy relative to the creamed butter, so the mixture can look slightly split before the dry ingredients are added. Once the flour mixture is added, the batter should come back together.

How do I keep the cake from sticking to the Bundt pan?

Grease and flour every ridge and crevice of the pan thoroughly, including the center tube. Let the cake cool in the pan for about 15 minutes before inverting. Turning it out too early can cause it to break, while leaving it in the pan too long can make sticking more likely.

Can I make this cake ahead of time?

Yes. The cake keeps well thanks to the sour cream, almond flour, and ground pistachios. You can bake it a day ahead, store it tightly covered at room temperature, and add the glaze before serving.
