Pretty. Cool. Cake. Book.

FishMama has written an ebook that's filled with inspiration for a baker's dozen of creative birthday cakes.

She starts with simple ingredients -- boxed cake mix, canned frosting, novelty candies, little "flags" made of toothpicks with illustrations taped to them -- and ends up with some super fun creations.

There are lots of helpful tips here. (Want a fix for those pesky crumbs that poke through your frosting?)

And also, very clear, step-by-step instructions for everything from surfer dude cake (you'll be the coolest mom around with the "sand castle" on your beach's shore) to a "What state are you in?" cake (a theme you can customize for kids off in college, travelers, or sports fans).

So go check it out -- now! Because while this book normally goes for $5.97, for the rest of today, February 27, you can get Pretty. Cool. Cakes and another of FishMama's ebooks, FishMama's Guide to Cooking with Children, for $2.

That's right. Two bucks.
