Cakes Cuban food Original baby shower cake designs that match the nurseries or shower themes. See photos. I once had to bake a cake 3 times. The first two times I baked the cake, it wouldn't rise properly. I was thinking it was the oven or that when my toddler distracted me, I had missed adding a levening agent. However, the culprit turned out to be a bad/old store-brand container of baking powder from my local grocery store. I had just bought the baking powder, so it didn't immediately occur to me that was the problem. I will never buy a generic again!
