Preparation:
Preheat your oven to 325°F. Grease and flour a 10 to 12-cup Bundt pan for easy cake removal.
Batter:
In a large bowl, use an electric mixer to blend the cake mix, vegetable oil, pineapple juice, and eggs. Beat for about 2 minutes until the mixture is smooth and well combined.
Baking:
Pour the batter into your prepared pan. Bake for 30 to 35 minutes, or until a toothpick comes out clean and the edges of the cake begin to pull away from the pan.
Glaze:
While the cake cools, start on the glaze. In a small saucepan, mix powdered sugar, pineapple juice, and butter. Warm over medium-low heat until the butter melts, stirring often.
Once the cake has cooled slightly, poke holes throughout with a skewer or toothpick.
