Preheat your oven to 350°F (175°C). Grease and flour a 10-cup Bundt pan or spray it with non-stick cooking spray.
In a large bowl, mix the yellow cake mix, instant vanilla pudding mix, vegetable oil, 3/4 cup pineapple juice, and the large eggs.
Beat with an electric mixer on medium speed for 2–3 minutes until the mixture is smooth and creamy.
Pour the batter into the prepared Bundt pan.
Bake for 40–45 minutes or until a toothpick inserted in the center comes out clean.
While the cake is baking, whisk together the powdered sugar, 1/4 cup pineapple juice, and melted butter until smooth.
Once the cake is baked, allow it to cool in the pan for 10 minutes.
Carefully invert the cake onto a serving plate.
While the cake is still warm, poke holes all over the top with a skewer or fork and slowly pour the glaze over the cake, letting it soak in.
Let the cake cool completely before slicing.
