120 grams all-purpose flour
3 grams baking powder
1.5 grams ground nutmeg
1.5 grams baking soda
1.5 grams salt
150 grams white sugar
56 grams butter, softened
30 grams white sugar
5 grams vanilla bean paste
2 egg whites
160 milliliters buttermilk
115 grams cream cheese, softened
56 grams butter, softened
10 milliliters lemon juice
5 grams lemon zest
330 grams powdered sugar, or more as needed
Gold luster dust and green and purple sanding sugars
Step 1
Preheat the oven to 175 degrees C (350 degrees F). Place paper cup liners in a 12-cup muffin pan.
Step 2
Prepare the cupcakes: In a large bowl, combine the flour, baking powder, nutmeg, baking soda, and salt. In another large bowl, use an electric mixer to blend 150 grams of sugar, softened butter, and vanilla until well combined. Add the egg whites one at a time, beating well after each addition. Alternately add the flour mixture, buttermilk, and remaining flour mixture, beating after each addition until just combined.
Step 3
Spoon the batter into the prepared muffin cups, filling each about 3/4 full, and smooth the tops with the back of a spoon.
Step 4
Bake in the preheated oven until a toothpick inserted into the centers comes out clean, 15 to 20 minutes. Cool in the pan for 5 minutes, then remove to a wire rack to cool completely, about 30 minutes.
Step 5
Meanwhile, prepare the frosting: In a medium bowl, blend together softened cream cheese, butter, lemon juice, and lemon zest with an electric mixer until light and fluffy. Gradually beat in powdered sugar until a spreading consistency is reached.
Step 6
Spread or pipe the frosting over the cooled cupcakes and decorate with luster dust and sanding sugars.
