Get Ready: Line two baking sheets with parchment paper – your easy clean-up secret! Set them aside.
Combine Dry: In a large mixing bowl, gently stir together your quick oats and salt. Set this bowl aside for a moment.
Start Melting: In a medium saucepan, place the butter over medium-high heat and melt it until it's lovely and golden.
Sweet Chocolate Base: Add the brown sugar, cocoa powder, and milk to the melted butter. Whisk continuously until the sugar is fully dissolved and the mixture just begins to softly boil. As soon as you see those gentle bubbles, promptly remove it from the heat. (Careful not to over-boil, or your cookies might become a little dry!)
Creamy Finish: Quickly whisk in the peanut butter and vanilla extract until the mixture is wonderfully smooth and creamy.
Mix It All Up: Pour this warm, delicious peanut butter-chocolate mixture over the oats in your reserved bowl. Using a wooden spoon, gently fold everything together until every single oat is perfectly coated in that luscious goodness.
Form Your Treats: Grab a 2-3 tablespoon cookie scoop (or just a regular spoon) and drop spoonfuls of the mixture onto your lined baking sheets, leaving about 1-2 inches between each cookie for them to set.
Cool and Set: Let these delightful cookies cool completely on the counter. They will firm up and flatten slightly as they chill to perfection.
Chill and Enjoy: Once fully cooled and set, store your amazing cookies in the refrigerator until you're ready to serve these easy, wholesome holiday treats!
