2 MINUTE BLUEBERRY SOUR CREAM CAKE

I made this for the kids today at snack time. I based it on this recipe for Raspberry Yogurt Cake, but I used sour cream instead of yogurt and reduced the amount of sugar.

3 tbsp. sour cream
2 tbsp. melted butter
1 eg
1/2 tsp. vanilla
6 tbsp. flour
2 tbsp. sugar
1 tsp. Epicure's cinnamon
1/2 tsp. baking powder
2-3 tbsp. frozen blueberries

Stir wet ingredients together and add dry ingredients. Fold in blueberries. Scoop batter into 2 greased Cake For One molds and microwave for 2 minutes.
