You may eat with your eyes first, but sometimes the most vital part of a meal is feeding your brain. No, we're not talking about turning into a zombie — we mean having some nerdy fun in the kitchen. That's the name of Rosanna Pansino's game on her YouTube cooking show, Nerdy Nummies, and now she's bringing her recipes to you in the  The Nerdy Nummies Cookbook: Sweet Treats for the Geek in All of Us. The book comes out Tuesday, November 3, but you can pre-order your copy now (or keep reading to find out how you can enter to win a copy).

But wait, there's more! Rosanna is also sharing some of her spookiest recipes on a Cooking Channel special — Ro's Tasty Treats: Halloween, airing on Oct. 25 at 8pm ET — with boo-tiful goodies including a scary-realistic brain cake and mummy pizzas good enough to raise the dead.

To trick out any of your nerdy parties — whether it's Halloween or Halo 5 — we're giving five of you each a copy of The Nerdy Nummies Cookbook: Sweet Treats for the Geek in All of Us. To enter the sweepstakes, check out some cool video game cakes, and then drop a comment below letting us know which is your favorite.

Before you do that, get a sneak peek at the cookbook with Rosanna's Cheeseburger Cupcakes recipe, featuring chocolatey brownie "burgers" and vanilla cake "buns."

So tell us, which of these cakes is worth dusting off the old Wii Fit? You must include your email address in the “Email” field when submitting your comment so we can communicate with you if you’re a winner. (But do not post your email address in the actual body of the comment.)
