Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line three baking sheets with parchment paper.
- In a mixing bowl, combine room temperature egg whites with granulated sugar and salt. Whip until stiff peaks form, about 5-7 minutes.
- Gently fold in ground pistachios, powdered sugar, cream of tartar, and cake flour into the whipped egg whites.
- Transfer the meringue mixture into a piping bag fitted with a round tip and pipe into even circles, about 7 inches in diameter, onto the baking sheets.
- Bake for 25-30 minutes, until the meringue disks are crisp outside but slightly soft inside.
- Prepare the pistachio buttercream by combining egg yolks, granulated sugar, and water in a heatproof bowl over simmering water until sugar dissolves.
- Transfer the egg yolk mixture to a stand mixer and beat until thick and pale, about 8-10 minutes.
- Gradually add room temperature unsalted butter to the yolk mixture, mixing thoroughly after each addition, then add vanilla extract and pistachio paste.
- Assemble the cake by placing one meringue disk on a platter and spreading a layer of buttercream on top. Repeat with remaining disks.
- Chill the assembled cake in the refrigerator for at least 30 minutes before serving.

Notes
Ensure all mixing bowls and utensils are grease-free for optimal egg white whipping. Chill the cake for at least 30 minutes after assembly for better slicing.
