INSTRUCTIONS:

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the all-purpose flour, ground pistachios, baking powder, and salt.
5. Gradually add the dry ingredients to the wet ingredients, alternating with the pineapple juice. Mix until just combined, being careful not to overmix.
6. Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula.
7. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.
8. While the cakes are baking, prepare the pineapple filling. In a saucepan, combine the crushed pineapple, granulated sugar, cornstarch, water, and lemon juice. Cook over medium heat, stirring constantly, until thickened. Remove from heat and let cool completely.
9. Once the cakes are baked, remove them from the oven and let cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely.
10. To make the frosting, beat the softened butter until creamy. Gradually add the powdered sugar, heavy cream, and vanilla extract, beating until smooth and fluffy.
11. Assemble the cake by placing one layer on a serving plate. Spread a layer of pineapple filling over the top.
12. Place the second cake layer on top and frost the top and sides of the cake with the prepared frosting.
13. Sprinkle chopped pistachios over the top of the cake for garnish.
14. Chill the cake in the refrigerator for at least 1 hour before serving to allow the flavors to meld together.
15. Slice and serve this Pistachio Pineapple Cake to enjoy a heavenly dessert experience that perfectly balances nutty and fruity flavors.
16. Store any leftovers in the refrigerator for up to 3 days.
