Mom's Missouri Cookies

• 1 stick of butter
• 2 cups granulated sugar
• 1/2 cup milk
• 4 tbsp cocoa powder
  
• 1 tsp ground cinnamon
• 1/2 cup peanut butter
• 2 tsp vanilla extract
• 3 cups rolled oats (Quick cooking oats are best but I used regular because I had them.)

Add the first five ingredients to a 4 qt. sauce pan. Bring to a boil, stirring. Boil for 1 minute.

Pour oats into a large bowl. Pour chocolate mixture in with oats and give it a good stir.

Place heaping tablespoons of batter onto wax paper like so. Place into the fridge for several hours to allow cookies to set.
