1/2 cup plus 2 tablespoons sugar
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1 pinch salt
1/2 cup plain yogurt
1/4 cup oil
zest of 1 orange
1 tablespoon orange juice
1 egg
1/2 teaspoon vanilla
Additional orange juice and powdered sugar for glaze (optional)
Preheat oven to 350ºF. Grease an 8-inch or 9-inch cake pan with cooking spray.
In a small bowl, combine the flour, sugar, baking powder, baking soda and salt. Whisk to combine.
In a second bowl combine yogurt, oil, zest, orange juice, egg, and vanilla. Mix well. Add wet ingredients to dry ingredients and fold together. Batter will be quite thick.
Spread the batter in the prepared pan. Bake at 350ºF for 20-25 minutes, depending on the size of your cake pan. The cake is done when it is a golden brown and a toothpick inserted near the middle comes out clean.
Allow to cool for 5 minutes in the pan, and then invert onto a cooling rack. Dust with powdered sugar or glaze to serve. Can be served warm, at room temp, or chilled.
To make a glaze, combine about 1 cup of powdered sugar with 2-3 teaspoons of orange juice. Stir to combine, adding more orange juice if too thick, or adding more powdered sugar if too thin. Spread over the cake and garnish with additional orange zest if desired.
