The first place to start here would be: WTF is a Buckeye? Hit it, Wikipedia:
The tree species Aesculus glabra is commonly known as Ohio buckeye, American buckeye, or fetid buckeye.
Oh. Let's start there then.

Ingredients
- 1 1/2 cups peanut butter
- 1 cup butter, softened
- 1/2 teaspoon vanilla extract
- 6 cups confectioners' sugar
- 4 cups semisweet chocolate chips
Directions
- In a large bowl, mix together the peanut butter, butter, vanilla and confectioners' sugar. The dough will look dry. Roll into 1 inch balls and place on a waxed paper-lined cookie sheet.
- Press a toothpick into the top of each ball (to be used later as the handle for dipping) and chill in freezer until firm, about 30 minutes.
- Melt chocolate chips in a double boiler or in a bowl set over a pan of barely simmering water. Stir frequently until smooth.
- Dip frozen peanut butter balls in chocolate holding onto the toothpick. Leave a small portion of peanut butter showing at the top to make them look like Buckeyes. Put back on the cookie sheet and refrigerate until serving.
You know, that doesn't sound like it has anything to do with trees at all. But that's okay! You'll need the additional sugar to put you in a good mood for tomorrow's game, since you're unlikely to be very happy with how that turns out.
Use this as your open thread for tonight's Washington State/UNLV game. Go Cougars!
