I remember cooking these in college with my good friend Leah. They're great for college kids because they don't require any "baking" ingredients like baking soda or baking powder (things college kids don't usually stock up their kitchens with). The other night, I wanted a chocolate-y treat and I wanted it fast. This was the perfect solution. Chewy, chocolate-y goodness.
1/2 cup (1 stick) butter
2 cups granulated sugar
1/2 cup milk
4 Tablespoons cocoa powder
1/2 cup peanut butter
2 teaspoons vanilla extract
3 cups quick-cooking oats
Add butter, sugar, milk, and cocoa powder to a 4-quart saucepan. Stir until butter is melted, bring to a rolling boil and let boil for about 1 minute. Remove from heat.
Stir in the peanut butter and vanilla until smooth, then stir in oats.
Drop by heaping tablespoons onto wax paper-lined baking sheets. Let cool until set.
