Pistachio carrot cake make more sense together than you might expect. This pistachio carrot cake has a soft, moist crumb filled with grated carrots and chopped pistachios, while browned butter adds a deeper, lightly toasted flavor. A little orange zest freshens everything up without making the cake taste overly citrusy.
The pistachio cream cheese frosting is smooth, nutty, and not too sweet, so it complements the cake instead of covering up its flavor. Finished with a handful of chopped pistachios, this two-layer carrot cake is simple enough to make at home but still feels special enough for Easter, birthdays, or a spring gathering.
Ingredients
Carrot Cake
- 1¾ cups (175 g) finely grated carrots
- ¾ cup plus 2 tablespoons (180 g) packed brown sugar
- 2 large eggs, plus 1 egg yolk
- 1 teaspoon vanilla extract
- 1 teaspoon finely grated orange zest
- 3½ tablespoons (50 g) unsalted butter
- 7 tablespoons (100 ml) vegetable oil
- ½ cup (60 g) pistachios, roughly chopped
- 1⅔ cups (200 g) all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- 1½ teaspoons ground cinnamon
- ¼ teaspoon salt
Pistachio Cream Cheese Frosting
- 12 ounces (350 g) full-fat cream cheese, cold
- 3½ tablespoons (50 g) unsalted butter, softened
- ¾ cup plus 1 tablespoon (100 g) powdered sugar
- 3 tablespoons (50 g) pistachio butter or pistachio spread
Instructions
- Prepare the pans: Heat the oven to 350°F (180°C), or 320°F (160°C) for a fan oven. Grease and line two 6-inch (15 cm) round cake pans. Grate the carrots and roughly chop the pistachios.
- Brown the butter: Melt the butter in a small saucepan over medium heat. Continue cooking, swirling the pan occasionally, until it smells nutty and the milk solids at the bottom turn golden brown. Pour it into a bowl and let it cool for 5 minutes.
- Whisk the eggs and sugar: Whisk the brown sugar, eggs, and extra yolk in a large bowl for 2–3 minutes. The mixture should become lighter in color, slightly thickened, and foamy on top.
- Add the wet ingredients: Whisk in the cooled brown butter, vegetable oil, vanilla, and orange zest. Stir in the grated carrots and chopped pistachios until evenly distributed.
- Finish the batter: Add the flour, baking powder, baking soda, cinnamon, and salt. Fold gently just until no dry streaks remain. Avoid overmixing, which can make the cake dense.
- Bake the cakes: Divide the batter evenly between the prepared pans and smooth the tops. Bake for 30–40 minutes, checking at 30 minutes. The cakes are ready when a toothpick inserted into the center comes out with a few moist crumbs. Cool in the pans for 10 minutes, then transfer to a wire rack and leave to cool completely.
- Prepare the frosting: Beat the softened butter and powdered sugar until smooth and creamy. Mix in the pistachio butter, then add the cold cream cheese. Beat on low speed only until combined. Mixing for too long can make the frosting loose.
- Assemble the cake: Spread frosting over the first cooled cake layer, then add the second layer. Cover the top and sides with the remaining frosting and finish with chopped pistachios. If the frosting feels soft, refrigerate the assembled cake for 20–30 minutes before slicing.
Tips for the Best Pistachio Carrot Cake
Grate the carrots finely: Finely grated carrots soften into the batter and keep the cake moist without leaving large pieces in the crumb. There’s no need to squeeze out their moisture.
Watch the browned butter closely: Once the milk solids turn golden and smell nutty, take the pan off the heat and pour the butter into a bowl. It can go from browned to burned quickly if left in the hot saucepan.
Measure the flour accurately: A kitchen scale gives the most reliable result. If you’re using cups, spoon the flour into the measuring cup and level the top instead of packing it down.
Don’t overmix the batter: Fold in the dry ingredients only until the flour disappears. Mixing for too long can make the cake heavier and less tender.
Cool the layers completely: Even slightly warm cake can soften the cream cheese frosting and cause the layers to slide. If necessary, refrigerate the cooled layers for 20 minutes before assembling.
Keep the frosting cold: Use cold, full-fat cream cheese and add it after beating the butter and powdered sugar. Mix only until smooth. If the frosting becomes too soft, refrigerate it for 15–20 minutes before decorating.
Choose your pistachio spread carefully: Pure pistachio butter gives the frosting a stronger roasted flavor, while sweetened pistachio spread makes it sweeter and creamier. Either works, but you may want to slightly reduce the powdered sugar when using a very sweet spread.
Make Ahead
The carrot cake layers can be baked one day ahead. Once completely cool, wrap each layer tightly and keep them at room temperature overnight. The frosting can also be prepared a day ahead and refrigerated in an airtight container. Let it soften for a few minutes, then stir briefly before using.
How to Store Pistachio Carrot Cake
Because the cake is covered with cream cheese frosting, keep it refrigerated in a covered cake container. It will stay fresh for up to 4 days. For a softer texture and fuller flavor, let individual slices sit at room temperature for 20–30 minutes before serving.
Freezing Instructions
The unfrosted layers freeze better than the assembled cake because cream cheese frosting can change texture after thawing. Wrap each cooled layer tightly in plastic wrap and then foil. Freeze for up to 3 months, which falls within the 2–4 month storage period recommended for baked cakes by the North Dakota State University Food Freezing Guide.
Thaw the wrapped layers overnight in the refrigerator, then bring them to room temperature before frosting.
