At least once a week after the kids are all in bed, James and I will make a big bowl of popcorn and these Small Batch Chocolate Chip Cookies to eat while we watch our shows.  (Currently: Mindhunters on Netflix, so good!)  That cookie recipe is perfect for the two of us because it only makes 4-6 cookies, depending on how big I make them. 

Sometimes I still have that sweet craving when James is on shift, but can’t justify making cookies for myself (even a small batch) + I’m usually too tired after mommin’ alone all day to even think about turning on the oven one more time!

Enter: this No Bake Peanut Butter Oatmeal Cookie FOR ONE!

No Bake Cookies

This No Bake Peanut Butter Oatmeal Cookies recipe is SO easy and only requires one tiny bowl and four ingredients that I always have on hand.  For this recipe, you will need:

  • Quick cooking oats (the instant kind)
  • Peanut butter (natural, crunchy, or smooth)
  • Powdered sugar (confectioners’ sugar) 
  • Vanilla extract

The yummy schmear of chocolate and generous sprinkling of flaky sea salt are optional… but strongly recommended.

Rolled Oats vs Quick Oats

The difference between steel-cut, rolled, and instant oats is simply how much the oat groat (the whole, unbroken grain) has been processed.  Ultimately, this results in each variety having a distinct texture and varying cook times, but the same nutritional value.  Instant oats, the most processed of the three varieties, are pre-cooked, dried, and then rolled and pressed slightly thinner than rolled oats.

For this No Bake Peanut Butter Oatmeal Cookies recipe you must use instant oats.

I love my Mom’s Classic Peanut Butter Cookies recipe because it yields perfectly soft cookies that just melt right in your mouth.  This no bake peanut butter cookie is like that cookies’ crunchy cousin.  I was worried that I wouldn’t like the texture of the oats, even though I use oats in my Oatmeal Chocolate Chip Oatmeal Cookies, but it was delicious! 

Bonus: I love that this recipe is packed with protein from the peanut butter and fiber from the oats.

  • 2 tbsp peanut butter
  • 2 tbsp quick-cooking oats (instant oats)
  • 1 tsp confectioners' sugar
  • 1/4 tsp vanilla extract
  • 1 tbsp semi-sweet chocolate chips
  • flaky sea salt


  • Combine peanut butter, heaping tablespoons of oats, sugar, and vanilla in a small bowl.
  • Transfer to a piece of parchment paper and use fingers to shape mixture into a 2 1/2in wide, 1/2in thick disk.
  • Freeze until firm, about 5-15 minutes.
  • Once cookie is cold and hard, melt the chocolate chips in the microwave at 15 second intervals until smooth.
  • Spread half of the cookie with melted chocolate and top with flaky sea salt.



The chocolate should set up immediately on the cold cookie, but you can pop it back into the freezer for a minute or two if needed.
