Ingredients
- Eggs: Provide structure and lift so use large eggs at room temp for best volume
- Angel food cake mix: Makes it feather light while holding up all the pineapple juices
- Vegetable oil: Keeps the crumb moist but neutral in flavor go for a fresh bottle for best results
- Crushed pineapple with juices: Brings tropical sweetness and extra moisture look for fruit packed in juice not syrup
- Cool whip: Delivers the classic fluffy frosting texture let it fully thaw for smooth mixing
- Pistachio pudding mix: Gives that iconic pale green hue and delightful nutty taste choose instant style for easy prep
- Whole milk: Thins and helps the topping set use whole for the richest taste

Instructions
- Mix the Batter:
- Combine the cake mix pistachio pudding mix vegetable oil eggs and the entire can of crushed pineapple with all juices in a large bowl. Mix everything on medium speed until you have a thick well combined batter with no dry spots usually takes about 2 minutes for everything to blend smoothly.
- Bake the Cake:
- Pour the batter into your greased 9 by 13 pan and spread evenly into the corners. Bake on the center rack in a preheated 350 degree oven for 30 to 35 minutes until the top is deeply golden and a toothpick inserted in the middle comes out clean without wet batter.
- Cool Completely:
- Let the baked cake rest in the pan on a wire rack for at least an hour. The cake needs to be fully cooled so the whipped topping does not melt or lose its texture when added.
- Prepare Pistachio Topping:
- In a medium bowl whisk together the second box of pistachio pudding mix with whole milk for about 2 minutes until it thickens to a soft pudding consistency. Gently fold in the thawed cool whip with a spatula until evenly combined and perfectly light.
- Frost and Chill:
- Spoon the pistachio topping onto the cooled cake and use a spatula to spread gently to the edges. Chill the whole cake uncovered for a minimum of 2 hours so everything sets up and flavors develop. Just before serving sprinkle a generous layer of chopped pistachios over the top for both looks and crunch.
Both kids and adults absolutely love this cake. The pistachio pudding is the secret ingredient for me I adore its springy green look but it is the cool whip that had me sneaking tastes out of the bowl just like when my grandma made it for Easter picnics.
Storage Tips
Keep leftovers tightly wrapped or in an airtight container in the fridge to help preserve the fluffy topping. The cake tastes great even after two to three days. Just know the chopped pistachios are crunchiest when added fresh.
Ingredient Substitutions
If you want to change things up try using coconut whipped topping for a dairy free version or swap in fresh whipped cream if you are feeling fancy. For extra fruity flavor you can add a handful of sweetened shredded coconut into the batter.
Serving Suggestions
Slice into generous squares and serve straight from the fridge for the ultimate summer treat. This cake pairs beautifully with fresh berries or mango slices for extra color and a refreshing finish.
Cultural and Historical Context
Pistachio pudding cakes are a nostalgic favorite across the Midwest and Southern United States usually popping up at family gatherings potlucks and church picnics. The tropical twist in this version makes it feel a bit like bringing a Hawaiian luau right to your table.
Seasonal Adaptations
Layer with strawberries or sliced kiwi for springtime flair. Try adding diced mango or papaya in summer. In the winter turn this into a holiday showstopper with ruby red pomegranate arils and caramelized nuts.
Success Stories
Once I brought this cake to a neighbor’s BBQ and not a single crumb survived. By the end of the night two people were asking for the recipe and agreed that the topping is the best part. For an after school treat this cake never fails to surprise and delight.
Freezer Meal Conversion
You can freeze the baked unfrosted cake tightly wrapped for up to two months. Thaw overnight before topping and serving. I do not recommend freezing the frosted cake as the texture of the whipped topping can become grainy after thawing.
Bright, easy, and festive, this cake brings sunshine to any table. Let every bite transport you to a sweet tropical getaway.
