- 1 package instant pistachio pudding mix (3.4 oz)
- 1 cup lemon-lime soda (such as Sprite or 7Up)
- ¾ cup coconut oil, melted (or vegetable oil)
- 3 large eggs
- ¾ cup sweetened shredded coconut
For the Frosting:
- 2 packages cream cheese (8 oz each), softened
- 1 cup powdered sugar

- ½ cup cold milk
- 4 oz whipped topping (Cool Whip), thawed

Step-by-Step Directions
Step 1: Prepare the Cake Pans
Preheat oven to 350°F (175°C). Grease and flour two 9-inch round pans or line them with parchment paper for easy release.
Step 2: Make the Cake Batter
In a large mixing bowl, combine cake mix, pistachio pudding mix, lemon-lime soda, melted coconut oil, and eggs. Beat on low until combined, then on medium for 2 minutes until smooth. Fold in shredded coconut.
Step 3: Bake
Divide batter evenly between pans. Bake for 22–25 minutes, or until a toothpick comes out clean. Cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
Step 4: Prepare the Frosting
Beat softened cream cheese until fluffy. Add powdered sugar and pistachio pudding mix, mixing well. Gradually add milk until smooth. Fold in whipped topping gently to keep it airy.
Step 5: Assemble the Cake
Place one cake layer on a serving plate. Spread frosting over the top. Add second layer and frost the entire cake.
Step 6: Decorate
Press toasted coconut into sides of the cake and sprinkle pistachios on top. Refrigerate until serving.
Baking Tips & Tricks
- Use Room Temperature Ingredients – Ensures smoother batter and frosting.
- Don’t Overbake – Pistachio cakes dry quickly; check at the minimum time.
- For Vibrant Color – Add 2–3 drops of green food coloring.
- Toasting Coconut – Bake shredded coconut on a sheet pan at 325°F (160°C) for 5–7 minutes until golden brown.
- Cooling the Cake – Make sure layers are completely cool before frosting to prevent melting.
Variations of Coconut Pistachio Pudding Cake
