Moist Pistachio Coffee Cake Recipe with Crispy Streusel
A soft, buttery coffee cake filled and topped with a crunchy pistachio streusel. This bakery-style Pistachio Coffee Cake is tender and nutty, balanced by warm buttery notes and a crisp pistachio streusel. It’s an ideal treat for breakfast, brunch, or an afternoon coffee break.
Deciding which part of this cake I love most is hard: the tender, flavorful crumb or the crispy, buttery streusel that flakes off onto the plate. Fortunately, you don’t have to choose—this cake features a layer of pistachio streusel in the center and another on top, so every bite combines soft cake with crunchy topping.
This recipe blends elements from two favorites—an Almond Crumb Cake and a streusel-topped apple muffin—resulting in a cake that’s as tender and fluffy as a muffin, but perfectly suited to a larger gathering. It’s comforting and easy to share, whether you’re serving it at brunch or enjoying a lazy morning at home.
The Ingredients
The full measurements appear in the recipe card below. Here are a few notes about key ingredients, their role in the recipe, and simple substitution ideas when appropriate.
- Lightly roasted, salted pistachios. Roasted pistachios deliver deeper, more developed flavor, and a touch of salt enhances that nuttiness. Use unsalted if preferred, but taste first and add a pinch of salt to the streusel if needed.
- Sour cream. Sour cream gives the batter body and moisture, which helps the cake stay tender and prevents the streusel layers from sinking.
- Optional flavorings. I tested adding ground cinnamon to the streusel and rubbing orange zest into the sugar. Cinnamon can feel overpowering to some; orange zest is nice but unnecessary. The pistachio flavor stands on its own. If you want a subtle twist, try 1/2 teaspoon cinnamon or 1/4 teaspoon cardamom in the streusel.
Let’s Bake!
This is a straightforward recipe, and the instructions are written to be clear. Below you’ll also find step-by-step photos to guide you. For the best results, pay attention to a few simple details:
- Read and prepare. Read the recipe through before you begin. Measure ingredients ahead of time so everything is ready when you need it—nothing derails a bake faster than forgetting baking powder or miscounting eggs.
- Room-temperature ingredients. Butter, eggs, and sour cream should be at room temperature to blend smoothly into a light batter. Cold ingredients can lead to a dense texture.
- Mixing method. Cream the butter and sugar with a stand mixer or hand mixer, then finish combining the flour with a whisk or spatula. This helps prevent overmixing and developing tough gluten.
- Layer carefully. Scoop the batter gently over the first streusel layer instead of spreading it aggressively. This reduces the chance of mixing the batter into the streusel layer and keeps the layers distinct.
- No inverting. Because of the streusel topping, this cake should not be inverted after baking. Use a springform pan if you have one, or allow the cake to cool completely in the pan before removing it to preserve the top layer.
Serving the Cake
Although it’s a cake, I usually serve this as a breakfast or brunch item rather than a dessert. A light dusting of powdered sugar is lovely, or you can add a drizzle of pistachio cream if you prefer a richer finish. The cake is delicious on its own—the pistachio flavor shines without much adornment.

Moist Pistachio Coffee Cake With Streusel
Ingredients
Pistachio Streusel
- 1 Cup (120g) Flour
- 1/3 Cup Sugar
- 2/3 Cup (100g) Chopped pistachios
- 6 Tablespoons (85g) Unsalted melted butter
Cake
- 2 Cups (240g) Unbleached all-purpose flour
- 2/3 Cups (100g) Ground pistachios
- 2 teaspoons Baking powder
- 3/4 Cup (180g) Sour cream
- 1 teaspoon Vanilla extract
- 3/4 Cup (170g) Unsalted butter at room temperature
- 1 Cup + 2 Tablespoons (225g) Sugar
- 1/4 Cup (60ml) Vegetable oil
- 2 Large Eggs at room temperature
- 1 Large Egg yolk at room temperature
Instructions
Make the Streusel
-
Measure the flour (120g), sugar (70g), and chopped pistachios (100g) into a large bowl. Pour the melted butter (85g) over the dry ingredients and use a fork or your fingers to combine until you have a moist, slightly lumpy streusel.
-
Tip: A lumpy streusel is fine—stop mixing once no dry flour remains. The irregular texture gives the topping great bite.
Make the Cake
-
Preheat the oven to 325°F (160°C). Grease the bottom and sides of a 9-inch pan and line the base with parchment paper.
-
In a large bowl, whisk together the flour (240g), ground pistachios (100g), and baking powder (2 teaspoons). In a separate bowl, mix the sour cream (3/4 cup / 180g) with the vanilla extract and set aside.
-
Cream the butter (170g) with the sugar (225g) until light and airy—about 4–5 minutes with a stand mixer or 2–3 minutes with a hand mixer. Scrape down the bowl as needed.
-
With the mixer running on low, drizzle in the vegetable oil (1/4 cup / 60ml). Then mix in the eggs one at a time, followed by the additional egg yolk.
-
Reduce the mixer speed to low (or switch to a whisk/spatula) and add the flour mixture in three additions, alternating with the sour cream mixture in two additions. Start and finish with the flour mixture. Mix each addition just until incorporated—there’s no need to fully develop the mixture between additions.
-
Spread half of the batter into the prepared pan, then sprinkle half of the pistachio streusel over it. Top with the remaining batter (use a cookie scoop if the batter is very thick to make this easier), then finish with the remaining streusel.
-
Bake on the middle rack for 50–55 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow the cake to cool and set before serving.
Notes
- Store the cake at room temperature, covered, for up to three days.
- Leftovers can be wrapped in plastic wrap, placed in a freezer bag, and frozen for up to three weeks. Thaw at room temperature before serving.
