One Bowl Vanilla Cupcakes for Two
1 egg white
2 tablespoons sugar
2 tablespoons butter, melted
1 teaspoon vanilla (yes, a full teaspoon – they are super vanilla-y!)
1/4 cup flour
1/4 heaping teaspoon of baking powder
pinch of salt
1 1/2 tablespoons milk
Preheat oven to 350 degrees. Line a muffin pan with 2 liners.
In a bowl, add egg white and sugar and whisk until combined. Add in vanilla and melted butter and stir until mixed. Add flour, baking powder and salt and stir until smooth. Stir in milk. Divide batter equally between the 2 cupcake liners.
Bake at 350 for 10-12 minutes, or until cake is set. Let cool completely, then frost as desired. I used some leftover white chocolate frosting.
