Separate egg whites into a mixing bowl and the yolks in another. Using the whisk attachment on your mixer, whip the whites while slowly adding 1/3 cup sugar. Beat for about 3 minutes until thick and stiff. Spoon the beaten whites into a clean bowl so you can reuse the mixer.

Beat the egg yolks with the other 1/3 cup of sugar in the mixer at high speed until light and fluffy, about 3 minutes. Add in the mascarpone and blend until smooth. Next, mix in the vanilla extract, almond extract, and pistachio paste until the mixture is creamy.

Scatter the chopped pistachios over the top. Cover and chill in the fridge for at least 4 hours, or leave overnight for the best taste. Take it out, slice, and enjoy!
