1 3/4 cup all purpose flour
3/4 cup sugar
1 tsp each baking soda and powder
1/2 tsp salt
1 egg
1/2 cup vegetable oil
1/2 cup sour cream or plain yogurt
1 tsp vanilla
1 cup banana
1 cup chocolate chips
Combine flour, sugar, baking powder, baking soda, and salt. Mix yogurt/sour cream, oil, vanilla, and egg just till combined. Stir in dry ingredients just till combined. Add banana and chocolate chips. Fill lined cupcake tin almost to the top, more than 2/3. These dome really nicely. Bake at 350 for 20-22 minutes (when edges are slightly golden). Cool on rack (if you can wait that long!)
