- Vegetable oil: brings moisture and a soft crumb Choose a neutral oil with no strong flavor
- Crushed pineapple: with all its juices infuses the cake with tropical sweetness Use canned pineapple in juice not syrup for the freshest flavor
- Cool whip: creates a cloudlike frosting Make sure it is fully thawed for smooth spreading

- Whole milk: helps the pudding set and adds richness Use cold whole milk for thick and creamy frosting

Step-by-Step Instructions
- Prepare Your Pan:
- Preheat your oven to three hundred fifty degrees and grease a standard nine by thirteen baking dish well so your cake lifts out easily
- Mix the Batter:
- In a generous mixing bowl combine the angel food cake mix one box of pistachio pudding mix vegetable oil eggs and the full can of crushed pineapple with its juices Beat with a hand mixer or sturdy spatula until the mixture is smooth and airy The batter should look pale green and glossy
- Bake the Cake:
- Pour the batter into your greased baking dish Gently tap the dish on the counter to pop air bubbles Slide it into your preheated oven and bake for thirty to thirty five minutes Keep an eye on color and test with a toothpick in the center for doneness It should come out clean with a crumb or two
- Cool Completely:
- Let the cake cool in the dish until it reaches room temperature This is key for easy frosting and prevents melting
- Make the Pistachio Frosting:
- In a medium bowl whisk together the second box of pistachio pudding and two thirds cup whole milk The mix will thicken quickly Stir until smooth then fold in all the thawed cool whip with a spatula Use gentle strokes to keep the frosting fluffy
- Frost and Decorate:
- Spread the pistachio frosting generously over the cooled cake Scatter the top with chopped pistachios pressing them lightly so they stick Cover and chill the cake for at least two hours before slicing to let the flavors blend and the frosting firm up

The pistachio pudding is a star ingredient A sprinkle of bright green pistachios on top makes this cake pop at a party The first time my little one helped with decorating he took such care arranging the nuts in patterns and now it is our special baking tradition
Storage Tips
Store leftovers covered in the refrigerator for up to four days The frosting stays soft and the cake remains moist Press wax paper onto the surface before covering for extra freshness If you want to freeze wrap unfrosted cake layers in plastic and then foil The frosting is best made fresh after thawing
Ingredient Substitutions
No pineapple No problem You can swap in drained mandarin oranges for a different citrus flair For a dairy free cake use plant based whipped topping and oat milk rather than cow’s milk The pistachio pudding can be replaced with coconut pudding if nuts are an issue but the flavor will shift to full tropical
Serving Suggestions
Cut this cake into small squares for a snack style dessert or into bold rectangles for a more show stopping presentation Garnish with extra pineapple rings fresh berries or a scoop of vanilla ice cream If you want extra crunch sprinkle a mix of coconut flakes and pistachios right before serving
