Step 1: Preheat and Prepare
Preheat your oven to 325°F (163°C). Grease and flour a bundt pan thoroughly or spray with baking spray containing flour.
Step 2: Mix the Cake Batter
In a large bowl, combine the yellow cake mix and vanilla pudding mix. Add the eggs, pineapple juice, vegetable oil, and vanilla extract. Beat on medium speed for 2 minutes until the batter is smooth and creamy.
Step 3: Bake the Cake
Pour the batter evenly into the prepared bundt pan. Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
Step 4: Prepare the Pineapple Glaze
While the cake is baking, prepare the glaze: whisk together the powdered sugar, pineapple juice, and melted butter in a medium bowl until smooth.
Step 5: Glaze the Cake
As soon as the cake comes out of the oven, use a skewer or toothpick to poke holes all over the cake while still in the pan. Slowly pour half of the glaze over the hot cake, allowing it to soak into the holes.
Step 6: Cool and Invert
Let the cake cool in the pan for about 15 minutes. Then invert it onto a wire rack or serving plate. Pour the remaining glaze evenly over the cake while still warm.
