There wasn’t much good that came from our public school cafeteria (besides that cheese pizza with the square pepperoni) but about once a week they got it right!! The day they made the from- scratch peanut butter oatmeal no bake cookies!!!!! Ohhhh yeaaaaaaah!

When that mean ol cafeteria lady plopped one of these down on your lunch tray it was like receiving a hunk of gold wrapped in plastic wrap! Kids went crazy over these cookies.  I couldn’t wait to crack open my milk carton and indulge in that creamy, sweet peanut buttery goodness.

Was I the only one that tried to sit next to the kid with the peanut butter allergy just to get first dibs on his cookie???…. Probably so. I was just as food obsessed then as I am now! Sad. Oh well.peanut butter oatmeal no bake cookies recipe

My mother always made the kind with chocolate which is great, but there is just something about the plain peanut butter that I will  never get tired of. Its been YEARS since I made these no bake peanut butter cookies. I’m talking over 15 years!!

Isaac didn’t have a clue what I was talking about so of course I just HAD to use this rainy afternoon to create a batch of good ol fashioned peanut butter oatmeal cookies! What mother wouldn’t want their child to be well versed in cookie knowledge.

There is something magical about baking with kids on rainy days. I love it!! We spent most of the afternoon lounging, reading books,  & eating cookies (waaaaay too many cookies) *sigh*.

These peanut butter no bake cookies are sweeeeeeeet, creamy and packing in all that peanut butter flavor. Did I say sweet? They’re amazing and addictive and one of my favorite cookies ever, ever, ever!! If you love peanut butter then please, you must make these. Like today! Because they are super easy and did you see that part that said “no bake”?

Yeah you don’t even have to turn on the oven. Just plop them onto wax paper, let them set and them get to enjoying them. A double win since I didn’t even have to go to the store for ingredients. I had everything right there!

It’s ALL about the peanut butter!!!

Because I wanted them to taste as old fashioned as possible I went with Skippy peanut butter! Even as an adult I still love that peanut butter! Now if you really want to get the real, authentic taste of these peanut butter oatmeal no bake cookies get your hands on some of that government peanut butter!! I kid you not, that’s the kind we had in the cafeteria. It was AWFUL on a choke sandwich (peanut butter sandwich) but throw that extra thick, pasty stuff in some cookies and my God!!! Talk about good!!

The Recipe

Old Fashioned Peanut Butter Oatmeal No-Bake Cookies

By Divas Can Cook
5.0 from 4 reviews

Ingredients

  • 4 tablespoons butter, chopped
  • 2 cups white sugar
  • 1 cup warm whole milk, divided
  • ⅛ teaspoon cream of tartar
  • 1 cup peanut butter
  • 1 teaspoon vanilla
  • 3 cups rolled oats, divided (1 minute quick oats)

Instructions

  1. Place 2 sheets of parchment paper on a counter or flat surface. Set aside.
  2. In a large nonstick pot or deep skillet, melt butter over medium heat.
  3. Stir in sugar and ½ cup milk until combined.
  4. Add in cream of tartar just when mixture begins to bubble slightly.
  5. Bring to a rolling boil and as soon as it comes to a roiling boil continue cooking for 2 MINUTES while stirring constantly. See note.
  6. Remove from heat.
  7. Stir in peanut butter and vanilla extract.
  8. Add half of the oats and stir until well combined.
  9. Stir in just enough of the remaining milk to create a thick and creamy batter. (may not need all of the milk)
  10. Stir in remaining oats.
  11. Working quickly, drop batter by the spoonful onto the parchment paper. Make them as big or as small as you'd like.
  12. Let the cookies sit for 20-30 minutes to set.
  13. Once set, wrap individually in plastic wrap and store in an airtight container.

Notes

ONLY BOIL FOR 2 MINUTES. If you boil too long the finished cookie will be dry, crusty and crumbly. If you don't boil long enough the cookies will not set. (This has happened to me before and I placed them in the fridge for about 20 minute to set them)

Best way to store: Wrap each cookie in plastic wrap and place in an airtight container. If you just store them all piled up in a container without wrapping them in plastic wrap they may stick together.
