Banana Cupcake Fail

I followed my recipe for the vanilla cupcakes.. I start to mix my dry ingredients; flour and sugar and i go to reach for the baking powder and wasn't on the counter.. I go to that cabinet and guess what It wasn't there either. So me being me I used baking soda. I use just a teaspoon of baking soda.. thought that might work ... i put the recipe together and then add the bananas.. bake them.. thought they would be fine. the batter tasted fine.. but when i went to eat one of them they tasted AWFUL. So next time ill make sure i have all of the ingredients...
