Ingredients

For the peanut butter, I use Jiff creamy peanut butter. But you could certainly use crunchy peanut butter or natural peanut butter.

You can use unsalted butter if that’s all you have. But the salted butter compliments the sugar in this recipe really well.

Supplies

Here are the kitchen supplies and equipment you need to make this recipe a success. I love that it’s a very short list, and no mixing bowl is needed.

The cookie scoop is not required, but it makes it quick and easy to measure out uniform-sized cookies.

The same goes for the baking sheet; you can use the waxed or parchment paper directly on the counter and save yourself some dishes. But some people like to use a lined baking sheet.

Recipe Instructions & Tips

Here are tips for how to have the best turnout each time you make this cookie recipe.

Make the peanut butter sauce

Begin by making the peanut butter sauce. Add sugar, milk, and butter to a saucepan. Use medium heat and stir often until ingredients have mixed well.

While my mixture is cooking, I like to measure out the oats and set them aside, so they’re ready when needed.

Once the mixture is melted and well blended, turn up the heat and bring to a boil for 90 seconds.

Remove from heat and stir in the peanut butter, mixing until it becomes a smooth, creamy consistency.

Fold in the oats

Next, stir in the oats and mix thoroughly. It should look similar to this:

…and so tempting to grab a spoonful and test it out.

Form cookies

You’ll want to prepare waxed or parchment paper, so the cookies don’t stick to your pan. Line two baking sheets with parchment paper (or waxed), or save yourself some dishes and lay the paper directly on the counter.

Using a cookie scoop, drop a heaping scoop onto wax paper. You can leave the shape as-is or flatten them a bit, making them easy to stack and store.

Cool & store

Allow the cookies to cool for 10 minutes or until you can easily remove them from the wax or parchment paper without them breaking apart.

Store in an airtight container until ready to serve. And there you have it, a delicious treat that takes only 20 minutes or less.
