They are so easy to do. All you need is:
1 3/4 cups white sugar
1/2 cup milk
1/2 cup butter
4 tablespoons unsweetened cocoa powder
1/2 cup crunchy peanut butter
3 cups quick-cooking oats
1 teaspoon vanilla extract
First, combine the sugar, milk, butter, and cocoa in a saucepan. Bring these to a boil, and then cook for 1 1/2 to 2 minutes. Remove the saucepan from the heat, and stir in the peanut butter, oats, and vanilla. Then drop by teaspoonfuls onto wax paper and wait for them to cool!
Boiling time is actually really important...boil for too long, and your cookies will be dry and crumbly. Don't boil for long enough, and they won't set. I've done it both ways! They still taste OK, but the consistency is a little off :)
After I dropped the cookies into the wax paper and let them cool for a few minutes, I took a fork and shaped them into hearts:
The hearts aren't necessary...plain old round cookies are just as good, but we all know that I am a sucker for hearts!
