These rich, chewy cookies contain no wheat flour or eggs, and—good news on sweltering days when you feel like having cookies around the house—require no oven heat. All you do is boil milk with unsalted butter and sugar to add to a mix of old-fashioned oats, chocolate chips, peanut butter, and vanilla. Mix, then form into cookies on waxed paper–lined baking sheets. Chill until the cookies set up, then gorge. For a fun twist, scoop your favorite ice cream flavor in between two cookies to make ice cream sandwiches.

Ingredients (7)

  • 1⁄4 cup unsalted butter (1/2 stick)
  • 1⁄4 cup whole milk
  • 1 cup granulated sugar
  • 1⁄2 cup semisweet chocolate chips
  • 2 1/2 tablespoons creamy peanut butter
  • 1 1⁄2 cups old-fashioned oats
  • 1 teaspoon pure vanilla extract

Instructions

  1. Add the oats, peanut butter, chocolate chips, and vanilla to a medium mixing bowl; set aside. Line 2 rimmed baking sheets with waxed paper and set aside.
  2. Combine the butter, milk, and sugar in a small, heavy saucepan set over medium-high heat. Boil for 1 minute.
