These no bake peanut butter cookies are soft, chewy, and incredibly easy to make with just six pantry ingredients. Perfect for quick snacks or crowd-pleasing desserts, they set without an oven and are ready in under 30 minutes.

Ingredients

Scale
  • 1/2 cup (115 grams) unsalted butter, cut into pieces
  • 1 and 3/4 cups (350 grams) granulated sugar
  • 1/2 cup (120 ml) milk
  • 3/4 cup (190 grams) creamy peanut butter
  • 1 teaspoon pure vanilla extract
  • 3 and 1/4 cups (325 grams) quick-cooking oats

Instructions

  1. Line baking sheets or a heat-safe countertop with parchment paper.
  2. In a medium saucepan over medium heat, combine butter, sugar, and milk. Stir frequently until butter is melted and mixture is fully combined.
  3. Bring mixture to a full rolling boil (the top should be bubbling vigorously) and boil for exactly 60 seconds without stirring.
  4. Remove from heat and stir in peanut butter and vanilla until fully combined and smooth.
  5. Stir in quick-cooking oats and mix until everything is evenly coated.
  6. Drop spoonfuls of mixture onto the parchment paper using a spoon or cookie scoop. Flatten slightly if desired.
  7. Allow to cool for 45 minutes to 1 hour or until fully set.
  8. Serve and enjoy, or store in an airtight container.

Notes

  • Use shelf-stable creamy peanut butter for best results. Natural peanut butter may prevent cookies from setting properly.
  • If using old-fashioned oats, pulse briefly in a food processor to make them finer.
  • Cookies can be stored at room temperature for up to 1 week or frozen for up to 3 months.
  • If cookies don’t set, refrigerate or microwave briefly and cool again.
