Another apple cake

I have purchased a cake pan made of alminum yesterday. It was to bake this cake. My wife me to measure the materials accurately or the cake won't be swollen. I was a bit nervous about it. I was relieved to see the cake starting to be swollen in 5 or 10 minutes in the oven. I am quite sure my wife used an old baking powder when she failed with it.

It is interesting to see the materials becoming a cake. No, I won't be a cake baker. No, possibly.
