Combine chocolate chips, peanut butter, butter, vanilla & sugar in a medium saucepan. Heat over medium heat adding rice milk as needed until the chocolate chips are melted and everything is creamy and smooth.
Pour over into a large mixing bowl and stir in oats until mixture is of a medium consistency. Drop spoonfuls of the mixture on a cookie sheet and refrigerate until the cookies are firm.
I also added some granola in with the oats and it was really good.
