Cook’s Notes

The use of 3 eggs and 1 egg in place of 4 whole eggs is the following reasons:

1. For fluffier cakes
2. To reduce sweetness – as yolks can amplify sugar’s heaviness
3. In citrus-based cakes like these orange pistachio cupcakes, where brightness benefits from less fat

Add eggs and egg white one at a time, mixing well after each addition. Next, add the buttermilk, orange juice, orange zest, vanilla extract, mix until combined.

Add the wet ingredients to the flour mixture and mix until just combined. Fold in the 2/3 cup chopped pistachios.

Divide batter evenly among prepared liners, filling each about 1/4 cup batter.

Bake in preheated oven for 18-22 minutes, or until a toothpick inserted comes out clean.

Cool in pans for 5 minutes, then transfer to wire racks to cool completely.

Make the Frosting

In a large bowl, beat cold heavy cream until soft peaks form. Set aside.

In another bowl, whisk together mascarpone, powdered sugar, vanilla, and salt until smooth.

Gently fold the whipped cream into the mascarpone mixture until fully incorporated.

Fold in ground pistachios.
