Prep Time: 10 minutes

Total Time: 45 minutes
Servings: 35 cookies

Ingredients

  • ½ cup unsalted butter
  • ¾ cup sugar
  • 3 tbsp unsweetened cocoa powder
  • ½ cup milk
  • tsp kosher salt
  • ¾ cup chunky peanut butter
  • 1 tsp vanilla extract
  • 3 cups quick oats also known as 1-minute oats

Instructions

Prepare the cooling surface.

  • Line a baking sheet or flat work surface with parchment paper. Set aside.

Melt the butter.

  • Place the unsalted butter in a saucepan over medium heat. Heat until fully melted.

Add the sugar, cocoa, milk, and salt.

  • Whisk the sugar, unsweetened cocoa powder, milk, and kosher salt into the melted butter until the mixture is smooth and fully combined.

Boil the mixture.

  • Increase the heat to high and bring the mixture to a boil. Boil for 1 minute, or until slightly thickened.

Remove from heat.

  • Remove the saucepan from the heat immediately after boiling.

Add the peanut butter and vanilla.

  • Stir the chunky peanut butter and vanilla extract into the hot chocolate mixture until the peanut butter is fully melted and the mixture is smooth.

Add the oats.

  • Add the quick oats to the saucepan. Stir until the oats are evenly coated with the chocolate peanut butter mixture.

Shape the cookies.

  • Using a small ice cream scoop or a 1-tablespoon measuring spoon, portion the mixture onto the prepared parchment paper. Shape each portion into a flattened cookie or leave it rounded, as preferred.

Cool the cookies.

  • Allow the cookies to cool at room temperature for 30 to 45 minutes, or until fully set.

Optional quick setting method.

  • To speed up the cooling process, place the cookies in the freezer for a short time until firm.

Serve.

  • Serve once the cookies are completely set.
