This recipe is great for both yellow and chocolate flavored cakes. It makes a light, fluffy, and seriously moist cake.
1 (18 oz) package yellow cake mix
1 tsp. vanilla
1 c. sour cream
1/8 c. powder sugar for dusting
Make the batter folling the directions on the box, EXCEPT replace 2 tsp water with an equal amount of vanilla. Fold in sour cream. Bake according to directions given for baking a bundt cake. Cool on rack, place on serving plate, and dust with powder sugar.
I've made this for several church functions and it gets good reviews. It's good if you need to make something quick!
