Pineapple Upside Down Cake (Aluminum Free)

Before I get to the pineapple cake, I'll comment on the aluminum part. I was unaware that baking powder contained aluminum until my good friend Amy pointed it out to me. I immediately looked at my baking powder, and there it was on the ingredient list, aluminum sulfate. I have not heard good things about ingesting aluminum, including a study that it may cause Alzheimer's. That is why I was so relieved to find this:
Bob's Red Mill Non-Aluminum Baking powder. Yay! This was my first time using it so I was anxious to see how the cake would turn out.

And now onto the cake. I'm currently writing a book that happens to mention food (not a surprise) and of course while writing, I started to crave baked goods. I thought about driving to the local bakery - a thirty minute round trip - but thought again and got out ingredients to make something of my own. I had a pineapple and decided pineapple upside down cake would fit the bill.Right after the cake came out of the oven:
And after the "flip."I didn't notice any difference with the new baking powder compared to my old (aluminum filled) baking powder I used in the past. And I have to say, it tastes just as good without the aluminum!
