Peanut butter fudge

A childhood classic.

1 stick melted butter
1 box confectionery sugar
2/3 cup cocoa
1 cup peanut butter (creamy)
1 teaspoon vanilla

Mix, press into pan.

That's it. You can let it cool if you want, but I usually just took a spoon and dug in.

Cost: around $1 each for the butter and box of confectioner's sugar, add another 75 cents for the other ingredients. $2.75 total, and this will fill a standard 8 x 8 casserole dish. That's...several days' worth of fudge. This stuff is good, but rich.
