                Prepare the yellow cake mix following package instructions for a 23x33 cm (9x13 inch) pan. Bake until edges are golden and a toothpick inserted comes out with moist crumbs, ensuring the cake remains moist.

                Combine crushed pineapple with juice and granulated sugar in a saucepan. Heat gently while stirring constantly until the mixture reaches a gentle boil and the sugar dissolves completely, about 2-3 minutes. Remove from heat.

                Immediately after baking, use a fork to poke holes approximately 1.3 cm apart across the hot cake surface. Pour the warm pineapple mixture evenly over the cake. Use a spatula to distribute pineapple pieces uniformly.

                Once the cake is completely cooled, beat together softened cream cheese and butter for two minutes until smooth and lump-free. Gradually add sifted powdered sugar in increments, beating well until a smooth, spreadable consistency forms.

                Fold chopped pecans gently into the frosting if using. Drop large dollops of frosting onto the cake and spread evenly from the center outward with a light touch to avoid disturbing the pineapple layer. Refrigerate for at least two hours before serving.
