Creating this incredible Lemon Pistachio Cake is straightforward if you meticulously follow these steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking powder, and salt.
3. Cream the Butter and Sugar: In another bowl, combine the softened butter and granulated sugar. Beat on medium speed until light and fluffy, about 3-5 minutes.
4. Add Eggs: Add eggs one at a time, mixing well after each addition until fully incorporated.
5. Add Zest and Juices: Mix in the fresh lemon juice, lemon zest, vanilla extract, and almond extract until well combined.
6. Combine Mixtures: Gradually add the dry ingredient mixture to the wet ingredients. Alternate by adding the milk and continue mixing until a smooth batter forms.
7. Fold in the Pistachios: Gently fold in the ground pistachios, ensuring they are distributed evenly throughout the batter.
8. Divide Batter: Pour the batter equally into the prepared cake pans, smoothing the top with a spatula.
9. Bake: Place the pans in the preheated oven and bake for 40-45 minutes. Test doneness by inserting a toothpick into the center; it should come out clean.
10. Cool: Once baked, remove the cakes from the oven and let them cool in the pans for about 15 minutes. Then transfer them to wire racks to cool completely.
11. Prepare the Frosting: While the cakes cool, make your preferred lemon frosting using butter, powdered sugar, and lemon juice. Make sure to have the desired consistency.
12. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread frosting on top, then add the second layer. Cover the entire cake with frosting.
13. Decorate: Garnish with whole pistachios and a dusting of powdered sugar if desired.

Following these steps will lead you to create an unforgettable Lemon Pistachio Cake that will impress all who taste it!
