1 cup all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
2 teaspoons white sugar for the top
1 egg
1 teaspoon vanilla extract for the bottom
Preheat oven to 375 degrees F (190 degrees C). Grease a 9x9 inch pan.
Sift flour into a large bowl. Stir in baking powder, baking soda and sugar. Mix well, and set aside.
In a small bowl, combine egg and vanilla. Beat egg mixture until well mixed. Stir in flour mixture, a little at a time, alternately with carrot and rice. Spoon batter into prepared pan.
Bake in preheated oven for 15 to 20 minutes, or until golden brown. Remove from oven, sprinkle with chopped green onions and serve warm.
