1 stick butter, melted
2 cups sugar
1/2 cup milk
4 tablespoons cocoa
2/3 cup peanut butter (I like crunchy)
2 teaspoons vanilla
3 to 4 cups oats
In a large saucepan, mix together the first 4 ingredients and bring to a boil; boil for 1 1/2 minutes. Stir in the peanut butter and vanilla until thoroughly mixed in. Stir in the oats until desired consistency is reached (I usually do around 4 cups) and then drop spoonfuls onto wax paper. Let set for a while and then they're ready to eat!
TIP: My friend and I always made these cookies when we were growing up and could never wait for the cookies to completely set, so we'd scoop the warm gooey cookie into a mug and pour a little milk on top—try it and you'll love it!
