No-Bake Peanut Butter Cookies

These classic No-Bake Peanut Butter Oatmeal Cookies commonly make appearances on lists of all-time favorite cookies. We’ve all likely made some variation of this recipe that I’m sure many of you are being hit with a wave of nostalgia right now. They are so simple and just so good that they’ve been around in some form for many years.

You may have also enjoyed these with the addition of chocolate to the batter. While I love that version, too, my inner peanut butter lover is always beyond thrilled to enjoy a couple of these little guys.

In many ways, these sweet, gooey cookies are more candy than cookie. These cookies aren’t baked, but are rather made on the stovetop. If you can melt things and stir, you’ve got this. Seriously, these are amazingly easy to make!

As you might expect, these little guys are a little sticky. Be sure to let them set well before serving, but you still may want to store them in the refrigerator to help them stay sturdy.

Tips for Success

  • Measure all ingredients before starting. You’ll need to move fairly quickly making these cookies, so it’s a great help to have everything measured and ready to go. That includes having the lined pans ready, too.
  • Use a large saucepan. You’ll need plenty of room for the bubbly mixture and for stirring the ingredients. I use a 3.5 quart heavy saucepan like the one linked below the recipe.
  • Use a cookie scoop to portion the batter. It will speed up the process and also make the size of the cookies consistent.
  • Don’t skip the chilling time. These gooey cookies need that stint in the refrigerator to set. You may want to store them in the refrigerator as well, especially during the warmer months.
  • Use natural peanut butters with caution. There’s quite a bit of variation among natural peanut butters, so it’s tough to say how well they would work in these cookies. Use regular peanut butter for the best and most consistent results.
  • Add more oats if you like. If you want these to be a bit more chewy and a little less gooey, then add up to another cup of oats.
  • Want to add some chocolate? Try melting some dark chocolate and drizzling on top of the cookies.

No-Bake Peanut Butter Oatmeal Cookies on a white pedestal


  • 1 & 1/2 cups (300g) firmly packed light or dark brown sugar
  • 1/2 cup (113g) unsalted butter
  • 1/2 cup (118ml) milk
  • 1 cup (255g) creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1 teaspoon salt*
  • 3 cups (297g) old-fashioned rolled oats


  1. Line baking sheets with parchment paper. Set aside.
  2. Place the brown sugar, milk, and butter in a large saucepan. Cook over medium heat, stirring occasionally, until the butter has melted.
  3. Increase the heat to medium-high, and bring to a boil. Boil for 1 minute.
  4. Remove the pan from the heat, and stir in the peanut butter, vanilla, and salt. Stir until smooth.
  5. Stir in the oats.
  6. Drop by tablespoonfuls onto the prepared pans, leaving about an inch between cookies.
  7. Refrigerate 1 hour, or until set.


*These cookies definitely fall into the sweet and salty category. If you prefer a less salty flavor, reduce the salt to suit your tastes.

  1. Can you substitute Nondairy butter and milk to make these?

    • Hi, Josie. I’ve not tried that, so I can’t say for sure how well it would work. These cookies are sensitive to temperature and boiling time, so my guess is that if it can work, you’d need to do some experimenting with the cooking and/or the other ingredients.

  2. Sounds great. I’m interested in how many carbs and sugar. I’m a diabetic! Thanks

  5. Thank you SO much for this recipe. Im type 2 diabetic on 2 insulins and these ingredients are everything i put in my favorite post workout breakfast (minus the salt). I substituted a diabetic sweeter for the brown sugar. Delicious!
