Baking!

Yesterday I didn't quilt.  My arm is giving me fits still and I was worried about hurting it further, so I decided to bake my husband that coffee cake he's been wanting me to bake.

I have a tried and true recipe that I know he likes, but I enjoy experimenting.  A few months ago I bought the book Flour

The cake tastes great. I just have no idea what I possibly did that caused that cratering effect.
