No-bake cookies are a sweet treat straight from grandma's recipe box. Don't miss the marshmallows, which form gooey puddles (!) or the shredded coconut!
Place the milk, butter, sugar, and cocoa in a medium saucepan. Place over medium heat and bring to a boil, whisking occasionally. Boil for 2 minutes. Remove from the heat.
In a large bowl, combine the oatmeal, peanut butter, vanilla, mini marshmallows, coconut, and walnuts. Pour the liquid mixture over the top and stir to combine.
Drop 2 tablespoons of the mixture onto parchment paper. Repeat with remaining mixture to create approximately 24 cookies.
Let cool for 1 hour before serving.
Notes
Make sure to drop the cookies onto parchment paper to ensure they don't stick! Wax paper or foil would also work. If you're using unsalted butter, add a half teaspoon of salt to the mixture. It'll balance the sweetness of the rest of the ingredients nicely.
