Author Notes: I adapted Grace Parisi's recipe for angel food cupcakes to include the citrus and I adapted Martha Stewarts Chocolate Buttercream recipe which made way too much frosting. The pairing of orange and chocolate together is delicious. The citrus is undeniable and to gild the lily I spread some orange marmalade on top of the cupcake before frosting. - sdebrango
Makes a dozen jumbo cupcakes
- 1 1/4 cup egg whites at room temperature
- 1 teaspoon cream of tartar
- 1 teaspoon orange zest
- 3/4 cups granulated sugar
- 1 cup cake flour
- 1/2 cup confectioners sugar

- 1. Preheat the oven to 325°. Set 12 jumbo foil muffin cups on a rimmed baking sheet. In a small bowl, combine the cake flour with the confectioners' sugar. In the bowl of your stand mixer, combine the egg whites with the salt, orange zest and cream of tartar and beat with whisk attachment until soft peaks form. Gradually beat in the granulated sugar, 1 tablespoon at a time, until the whites are firm and glossy. Sift the flour mixture over the egg whites in 2 additions, folding gently until incorporated.
- Spoon the batter into the muffin cups filling to the top. Bake for 15 minutes, checking the cupcakes starting at 13 minutes (ovens vary) shifting the pan from front to back, until the cupcakes are springy and golden. Transfer the cupcakes to a rack to cool
