Preheat your oven to 350 degrees F and grease a 10-12 cup bundt pan with butter or baking cooking spray.
In a large bowl, mix together the pineapple juice, melted butter, and cake mix until smooth. Add in the eggs and crushed/ chunk pineapple and mix on high speed for 2 minutes. Transfer to prepared bundt cake pan.
Bake the pineapple cake in the preheated oven for 35-40 minutes, or until a toothpick placed into the cake comes out clean. Allow the cake to fully cool.
Meanwhile, mix together your glaze ingredients in a small saucepan and cook over medium heat until the butter has melted through. Remove from heat.
Using a straw or skewer, poke holes throughout the bottom of the cake. Pour 1/3 of the glaze over the bottom of the cake and allow to cool for 10-15 minutes. Flip the cake over onto a serving platter. Add 1.5 cups powdered sugar to the remaining glaze & spoon over the top. Serve and enjoy!
NOTE: Adding the additional powdered sugar to the glaze is optional, but it does allow for the glaze to be more visible on the cake.
