In a large bowl, combine cake mix, dry pistachio pudding mix, oil, eggs, and undrained pineapple.
Beat with a hand mixer or whisk 2–3 minutes until smooth and slightly thickened.
3. Bake to Perfection
Pour batter into prepared pan; spread evenly.
Bake 30–35 minutes, until a toothpick comes out clean and edges pull away slightly.
Do not overbake—this cake stays soft even when fully cooked.

Let cool completely in pan (about 1–2 hours).
Spread with whipped topping just before serving (keeps it fresh).
