1-Prepare: Start by measuring out all your ingredients to keep things organized and avoid any rush.

2-Lining baking sheets: First, line two large baking sheets with parchment paper to make dropping the cookies easy and mess-free.

3-Cooking mixture: In a large saucepan over medium heat, combine the butter, sugar, milk, and cocoa powder; stir until the butter melts and everything mixes well. Bring this mixture to a rolling boil and let it boil for exactly 60 seconds while stirring occasionally use a timer to get it right, as this step ensures your cookies set properly.

4-Mixing: Once off the heat, stir in the peanut butter and vanilla extract until smooth, then mix in the oats until they’re fully coated. For a fun variation, you could add extras like nuts, but stick to the basics here for the classic version.

5-Shaping and setting: Drop spoonfuls of the mixture onto your prepared sheets and flatten them slightly; let them cool and set at room temperature for 20 to 30 minutes.
