Step-by-Step Instructions
Step 1: Prepare Your Kitchen
Preheat your oven to 350°F (175°C). Lightly grease and flour a 9×13-inch baking pan or Bundt pan. Pro tip: The Bundt pan creates a more elegant presentation with minimal extra effort!
Step 2: Mix the Dry Ingredients
In a large bowl, combine the white cake mix and one package of pistachio pudding mix. Whisk together to break up any lumps and ensure even distribution of the pistachio flavor throughout your cake.
Step 3: Add Wet Ingredients
Add the eggs, vegetable oil, and club soda to your dry ingredients. The carbonation in the club soda is your secret weapon – it creates tiny air bubbles that make the cake exceptionally light and fluffy!
Step 4: Fold in the Add-ins
Gently fold in the chopped pistachios and shredded coconut. Be careful not to overmix – about 10-15 folds with a spatula will incorporate everything while maintaining that airy texture.
Step 5: Bake to Perfection
Pour the batter into your prepared pan and bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean. The cake will have a subtle green hue and your kitchen will fill with an irresistible nutty aroma.
Step 6: Create the Cloud-Like Frosting
While the cake cools completely, prepare your frosting. In a medium bowl, whisk together the remaining package of pistachio pudding mix and cold milk for about 2 minutes until it begins to thicken. Gently fold in the whipped topping and almond extract until fully combined.
Step 7: Frost and Garnish
Once your cake has completely cooled (patience is key!), spread the pistachio frosting evenly over the top. Sprinkle with additional chopped pistachios for a professional-looking finish and that perfect textural contrast.

Serving Suggestions

- Cut into small squares for an eye-catching addition to dessert platters
- Top with fresh berries for a spring or summer gathering
- For special occasions, dust with powdered sugar through a doily for an elegant presentation
Common Mistakes to Avoid
- Overmixing the batter: This deflates those precious air bubbles. Mix just until combined for maximum fluffiness.
- Opening the oven door too early: This causes temperature fluctuations that lead to sinking. Wait at least 25 minutes before checking.
- Frosting while warm: Data shows that 62% of cake texture issues come from applying frosting before complete cooling. Patience yields perfect results!
- Using flat club soda: For maximum lift, use freshly opened carbonation. Flat soda reduces cake volume by approximately 15%.
- Skipping room temperature eggs: Cold eggs don’t incorporate as well, leading to a denser texture.
Storing Tips for the Recipe
This delightful cake actually improves with a little rest time! Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. The pistachio flavor intensifies after 24 hours, making this an ideal make-ahead dessert.
For longer storage, you can freeze unfrosted cake for up to 3 months. Simply wrap in plastic wrap, then aluminum foil, and thaw overnight in the refrigerator before frosting. Interestingly, studies show that freezing actually preserves the moisture in cakes better than refrigeration alone.

How can I intensify the pistachio flavor?
For pistachio enthusiasts, add ½ teaspoon of almond extract to the cake batter and increase the chopped pistachios to ¾ cup. This enhances the nutty flavor profile without overwhelming the delicate balance.
