Chocolate Oatmeal No-Bake Cookies

Line one large, or two small baking sheets with parchment or waxed paper.

Pour evaporated milk in a measuring cup and add cocoa. Whisk to make a slurry. Pour the slurry into a heavy saucepan and add sugar and butter.

Heat on medium, whisking continuously, until mixture comes to a full boil. Boil 2 minutes while constantly whisking. Remove from heat and stir in peanut butter and vanilla with a wooden spoon.

Stir in oats and nuts and continue stirring (do not beat, just stir) for exactly 2 minutes. Mixture should still look a bit shiny.

Immediately drop by tablespoon onto baking sheets. A cookie scoop is helpful for this.

Let cool until set completely, about 30 minutes. Store in a covered container at room temperature.
