Everything in this book is cooked in a muffin pan, whether it be mini muffins, regular muffins, or even the jumbo/Texas-sized muffins. However, it's not only your typical sweet muffins. Even those familiar ones have a creative twist, such as blueberry French toast muffins and apple cinnamon oatmeal cakes. There are muffin chapters for every part of a meal: breakfast, appetizers, side dishes, main dishes, dessert (and even a recipe for jello shots near the end).
The focus of this book is being able to make food that is easy to munch, share, and/or transport because of its muffin shape and structure. It also pushes the reader to use up leftovers in new ways to create something different yet delicious. The recipes aim to be easy but tasty, and the author is unafraid to use pre-made biscuit dough, puff pastry, wonton wrappers, French bread, a can of baked beans, frozen shredded hashbrowns, etc. As the author says in this book, the recipes are largely "just how I like it: fancy-sounding but easy to make."
There are many kinds of flavors and styles in the recipes, such as eggs benedict casserole cups, southwest eggroll bundles with chipotle cream sauce, caprese polenta bites, cheesy herb popovers, latkes with compote, and more. There's even a recipe for mac 'n' cheese and tips on hosting your own mac 'n' cheese bar. Note that if you have particular dietary restrictions most recipes in this book have at least one of these: eggs, meat, flour/bread products, or milk/butter/cheese/dairy.
This cookbook leans more toward easy and casual, and some recipes are even specifically noted as "kid-friendly". Additionally, because of this book's beginning as a blog, it is unsurprising that some recipes have short anecdotes before them. Luckily these are kept to a minimum and are a single paragraph at most. The biggest problem I saw with the book was that the editor didn't seem to do a final check: some notes even say "see page TK"-- "TK" is an editing symbol that means for you to come back and change something!
Besides the lack of final editing, this is a pretty good cookbook for someone who wants to make food that travels well, makes for great party-sharing munchies, or serves as portion-controlled and easily frozen meals and snacks.
