To break the general nonfiction category down to a manageable size , here are my picks for humor and baking:

Humor:

Sh*t My Dad Says, by Justin Halpern
This was funnier and had more depth than I expected it to be, considering it was spawned from a Twitter account. The quotes of the dad in question are organized thematically into categories and separated by short essays. This book really is laugh-out-loud funny (e.g., On Accidentally Eating Dog Treats: “Snausages? I’ve been eating dog treats? Why the f**k would you put them on the counter where the rest of the food is? F**ck it, they’re delicious. I will not be shamed by this.”)

Bossypants, by Tina Fey, and Is Everyone Hanging Out Without Me? (And Other Concerns), by Mindy Kaling
I wrote about these together on the library’s “staff picks” book review section. They are both in short essay format, easy to read a little at a time or straight through; but more importantly, they are smart and funny. If you like 30 Rock (Fey) or The Office (Kaling), chances are you will like these books. (Also, I found out that Mindy wrote my all-time favorite episode of The Office, “The Injury,” wherein Michael grills his foot on a George Foreman, Dwight gets a concussion, and Jim sprays him in the face with a squirt bottle. But that is neither here nor there.)

Cookbook:

Good to the Grain, by Kim Boyce
This was one of my staff picks, too. Boyce is a pastry chef and a mother, so her goal is to make healthy recipes without sacrificing any of the deliciousness – and by and large, she succeeds. Every recipe (especially the whole wheat chocolate chip cookies) I’ve made from this book has been a success. The sections are organized around the type of flour the recipes require, so you can try out one type at a time.
