This easy pistachio pudding cake is made with just six ingredients, including yellow cake mix and instant pistachio pudding, for a moist, fluffy, and foolproof dessert. I’ve been making this recipe for over 30 years, and it’s perfect for holidays, parties, or anytime you want a simple, charming cake.
In a large mixing bowl, whisk together 1 box yellow cake mix and 1 (3.4 oz) box instant pistachio pudding mix.
Add 4 large eggs, ½ cup vegetable oil, 1 cup club soda, and 1 teaspoon almond extract, then mix on medium speed for 1–2 minutes until smooth.
Grease a bundt pan or 9x13 cake pan generously with butter or nonstick spray, making sure to coat all edges.
Pour the batter into the prepared pan and smooth the top.
Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10–15 minutes, then turn it out onto a serving platter and cool completely.
Pistachio Pudding Frosting
In a mixing bowl, combine 1 (3.4 oz) box instant pistachio pudding mix, 1 cup heavy cream (8 oz), 1 cup milk (8 oz), and 1 teaspoon almond extract, then beat on high speed for 2–3 minutes until light and fluffy.

Notes
How to Tell When a Pistachio Pudding Cake Is Done
The cake pulls away from the sides of the pan: You’ll notice the edges naturally separating from the pan when it’s fully baked
The top is lightly golden: The surface should look set with a soft golden color, not wet or shiny
It smells fragrant: A warm, sweet pistachio aroma is a good sign that the cake is ready
Toothpick test: Insert a toothpick or knife into the center; it should come out clean or with a few moist crumbs (not wet batter)
Springs back when touched: Gently press the center of the cake, and it should bounce back instead of sinking.
