Before getting started, make sure to gather all of your ingredients and measure everything out. Line two large baking sheets with parchment paper and set aside.

Combine the butter, sugar, milk, and unsweetened cocoa powder in a large saucepan and heat over medium heat, making sure to stir often until the butter is melted and everything is well combined. Bring the mixture to a rolling boil and allow to boil for 60 seconds stirring occasionally.

Remove from the heat, and stir in the peanut butter and vanilla extract until fully combined. Stir in the oats and mix until all of the oats are coated with the mixture and everything is well combined.

Drop spoonfuls of the mixture onto the prepared baking sheets 

Allow to cool for 20 to 30 minutes, serve, and enjoy!
