What You’ll Like About This Recipe

• White or yellow cake mix – Provides structure and sweetness while keeping the recipe simple. White mix gives the brightest color; yellow adds a slightly richer flavor.
• Instant pistachio pudding mix – Adds moisture, nutty flavor, and a light green tint. Be sure to use instant pudding, not cook-and-serve.
• Eggs – Bind the batter and provide lift. Room-temperature eggs incorporate more smoothly into the mixture.
• Vegetable oil – Keeps the crumb moist and tender. Canola oil or any neutral oil works well here.
• Ginger ale or club soda – Adds lightness and extra moisture. Ginger ale gives a subtle sweetness; club soda keeps the flavor more neutral.
• Vanilla extract – Boosts flavor and rounds out the sweetness in both the batter and glaze.
• Sour cream – Adds richness and moisture, helping the cake stay soft for days.
• Pistachios – Finely chopped nuts add texture and a boost of real pistachio flavor. Use lightly salted pistachios and adjust overall saltiness as needed.
• Powdered sugar – Forms the base of the glaze and dissolves easily for a smooth finish.
• Milk – Thins the glaze to a pourable consistency. Start with less and add more until desired thickness is reached.

Ingredient Notes

• Cake mix: Use white or yellow cake mix—either works as a neutral base for pistachio flavor.
• Pudding mix: Be sure to use instant pistachio pudding (3.4 oz box); it adds both moisture and flavor.
• Eggs: Add structure and richness.
• Neutral oil: Canola or vegetable oil helps keep the crumb soft.
• Club soda or ginger ale: Adds lift and a subtle sparkle to the batter.
• Sour cream: Provides moisture and a touch of tang to balance sweetness.
• Pistachios: Chop them finely so they disperse evenly in the batter and on top.

How to Make the Cake

1. Prepare the Bundt pan thoroughly by greasing, flouring, or spraying it to ensure clean release. Heat the oven so the batter goes into a fully preheated environment.
2. Combine the cake mix, pudding mix, eggs, oil, ginger ale, sour cream, and vanilla. Mix on low first to prevent splashing, then increase to medium to fully blend the batter and incorporate air.
3. Fold the chopped pistachios gently into the batter. Folding keeps the nuts evenly distributed without deflating the mixture.
4. Pour the batter into the prepared Bundt pan and smooth the top. Bake until the cake springs back lightly when touched and a tester comes out clean.
5. Cool the cake in the pan to allow the structure to set, then invert onto a cooling rack to finish cooling completely before glazing.
6. Whisk the powdered sugar, milk, and vanilla to create a smooth glaze. Adjust thickness as needed so it drips slowly over the edges of the cake.
7. Spoon the glaze over the cooled cake and garnish with chopped pistachios for color and extra flavor.

Pro Tips

• Grease the Bundt pan carefully, paying attention to crevices, for clean release and sharp detailing.
• Mix the batter just until smooth; overmixing can make the cake denser.
• Test for doneness with a toothpick or by pressing gently—Bundt cakes can appear finished before the center is fully set.
• Cool the cake completely before glazing to prevent the glaze from melting.
• Chop the pistachios finely so they disperse evenly without sinking in the batter.

Recipe Variations

• Pistachio-chocolate swirl. Spoon a portion of the batter aside and mix in a tablespoon of cocoa powder, then swirl it into the pan for a marbled effect.
• Almond-pistachio cake. Add a teaspoon of almond extract along with the vanilla for a more pronounced nutty flavor.
• Citrus pistachio cake. Add a teaspoon of lemon or orange zest to the batter for a bright, fragrant twist that pairs well with the pistachio flavor.
• Cream cheese glaze. Replace part of the milk with softened cream cheese to create a thicker, richer topping that clings to the cake.
• Nut-free version. Omit the pistachios entirely for a smooth, tender cake still packed with pistachio flavor from the pudding mix.

Serving Suggestions

• Serve with fresh berries or sliced fruit to add color and a bright contrast to the nutty sweetness.
• Add whipped cream or a scoop of vanilla ice cream for a more decadent presentation.
• Pair with hot tea, pistachio latte, or coffee for a lovely afternoon treat.
• Choose to dust the cake lightly with powdered sugar instead of glazing if you prefer a simpler finish.

How to Store

• Room temperature – Store covered at room temp for 3 to 4 days. The sour cream and pudding mix keep the cake moist, making it ideal for countertop storage.
• Refrigerate – Keep the cake in an airtight container for up to 5 days. Chilling helps the glaze firm up and gives the cake a slightly denser texture.
• Freeze – Wrap slices or the whole cake tightly and store in a freezer-safe container for up to 3 months. Thaw at room temperature before serving, and glaze after thawing if freezing unglazed.
