Blood Orange Lemon Cupcakes

Directions

1. Prepare Lemon Curd (instructions below) and set aside.
2. Preheat oven to 350 degrees F and line two 12-cup standard muffin pans with baking cups.
3. Whisk together cake flour, baking powder, baking soda, and salt in a medium bowl.
4. Beat butter and sugar in a large mixer bowl at medium speed until light and fluffy; beat in Blood orange zest, lemon zest, and vanilla.
5. Add eggs one at a time and beat until combined.
6. Combine buttermilk and Greek yogurt in a small bowl. Reduce speed to low and add flour mixture in 3 additions, alternating with buttermilk mixture (begin and end with flour mixture).
7. Use a medium cookie scoop coated with nonstick spray to fill each baking cup 2/3rds full of batter.
8. Bake for 18 to 20 minutes, until cupcakes spring back to the touch and a toothpick inserted in the center comes out clean.
9. Let cupcakes cool in pans on wire racks for 2 minutes before removing from pans to cool completely.
10. To fill the cupcakes, use a small paring knife to cut a small cone out of the center of each cupcake. Fill each cupcake with a spoonful of lemon curd.
11. Make frosting (instructions below) and transfer to a large piping bag fitted with a large star tip and decorate cupcakes. Chill 20 minutes before serving.
12. Store leftover cupcakes covered in the refrigerator up to 3 days. Bring to room temperature before serving.
