Nate the Great and the Monster Mess by Marjorie Weinman Sharmat illustrated by Martha Weston*

My first grader read this book to himself.  This is his review:
"I like it because Nate the Great's mom asks him to find her monster cookie recipe.  He starts looking for it.  He looks in the pile of recipes.  He can't find it.  Then two hours later he comes home from the store.  He looks through the recipes again.  He finds a piece of paper that says "lemons" on it.  He flips the paper over and discovers the Monster Cookie recipe!"
*Highly recommend.
