As I’m wondering around in my kitchen, trying to get inspiration from ingredients in every cupboard, I come across the large jar of peanut butter.  

Does that really surprise you?  Because, if you’ve been hanging out over here, you’d know that peanut butter is my fave!

My first go-to search area in the kitchen, is usually my baking pantry.  That’s where I head when I’ve got a snacking situation going on.  Wouldn’t you?  I keep a wide variety of chocolate chips, marshmallows, and candy… to bake with, of course.   Or, are you the type to head straight to the refrigerator?

So, back to the jar of peanut butter…. it happens to be right  next to the oatmeal.  Which is then, across from the pantry of chocolate chips!  See where I’m going with this?  The makings of a no-bake creation… in a bar form!  Then you can cut out whatever size or shape you want.  Isn’t that perfect?!

This is usually my go-to recipe on a Wednesday night.  Why, you ask?  

One, these bars are fast to put together and I am not a night time baker.  

And two, they’re for my milkman– which arrives with my dairy in the wee hours the next morning.  The poor dude drives in mad snow storms, icy canyon roads, and passes deer ready to jump out in front of him!  The least I could do is leave him a little thank you treat out on the porch.

Making these are a breeze.  

But, to be honest, waiting for them to set up is really hard to resist!  If you are the impatient type, like me, you could scoop the oatmeal and peanut butter mixture onto a flat surface for individual cookies.

  1. 3/4 cup unsalted butter
  2. 1 1/2 cup granulated sugar
  3. 1/2 cup milk (I use whole milk.)
  4. 1 teaspoon vanilla
  5. 1/2 cup creamy (or crunchy) peanut butter
  6. 3 3/4 cup old fashioned oats/oatmeal
  7. 1 1/4 cup semi-sweet chocolate chips
  1. Melt butter in a large sauce pan on medium heat, .
  2. Once the butter has melted, add the sugar, milk, vanilla, and peanut butter. Whisk until combined.
  3. Turn the heat up to medium-high heat and bring the mixture to a boil for 4 minutes, while continuing to whisk.
  4. Take the sauce pan off the heat and add the oats. Stir until all combined.
  5. Spread the mixture evenly in a lined 9 inch by 9 inch baking dish. (No need to use non stick spray.)
  6. Immediately sprinkle chocolate chips on top of the oats mixture. The heat will start to heat up the chocolate chips to melt them. Within about 5 minutes, the chocolate will be ready to spread across with the back of a spoon.
  7. Allow to completely cool before cutting into squares.
  1. Set in a 9 inch by 9 inch dish. Cut into 12 pieces or 24 small pieces. For an alternative, you may scoop the oatmeal and peanut butter mixture onto a flat surface for individual no-bake cookies.

I hope you enjoy these No-Bake Oatmeal Peanut Butter Bars as much as the Milkman!

      Paula, that’s how I am when I get into the candy isle… what to make with it. But, then I get ‘snacking’ on the bag and have to buy another for the actual creation! 🙂

    Ummm first of all, you have a milk man?? What?! That’s the most amazing thing I’ve ever heard, I didn’t even know milkmen existing anymore. Second, these bars look so scrumptious, the perfect dessert/snack!

  4. says

    Made these bars for my husband,he raved about them to everyone at work! Had to make second batch. This will probably be my new go-to when it’s too hot to bake!

    • says

      Bonnie, I’m so happy you loved them! These will a perfect treat for this summer so we don’t have to use the oven … if it ever gets to be summer, right?! Thanks so much for stopping by to tell me how they turned out for you! 🙂

    What happens if I use the quick oats? I don’t have any others in the house and I need to whip these up quick! thanks

  8. Anne says

    Hey! I have a question…I made this just as directed and they did not set up…ever. Almost like eating raw dough…except even mushier than oatmeal cookie dough would be. I felt like the margarine/butter was way too much….are you sure you mean 3/4 cup and not 3/4 stick?? Just trying to figure out what went wrong!!! They taste delicious, by the way, but you just would need a spoon to eat them at room temp!!

      • Cherise says

        Mine were quite crumbly … I’m wondering on the boiling if you start timing 4 minutes when you turn it up to medium-high, or if you turn it up to medium-high, and when it starts to boil you time 4 minutes. I did the former and so it boiled for maybe 2.5-3 minutes. Quite a rapid boil.

        • says

          Yes, start timing once you come to a hard boil. By doing it this way, it will completely dissolve the sugar and therefor bind better together. Thank you for stopping by! 🙂

    I made these bars a couple of weeks ago and they were the absolute best. They will replace the bars I buy from the store. I shared with friends and family and they all loved them. I did cut down the sugar by about a 1/4 cup which doesn’t affect the consistency at all. I cut them and wrapped individually in foil and labelled. Put them in an airtight container and stored in the fridge. The last one was just as fresh as the first one. It also stopped me from eating them all at once. lol Now how do I apply for this milkman job? 😉

    Hi there!I made these bars exactly how instructed but they turned out pretty dry and crumbled….they didn’t stay in bar form. Should u cut them right after they cool because I didn’t get to cut and eat them til the next day. I can’t think what the problem would be. They tasted good though 🙂

    • says

      When I make these (at least a few times a month), I will almost make them the night before so I can cut into them the next day. But the bars are always good for a couple days just left out (uncovered) and if they can last more than a day without being devoured. I’m not quite sure what would have made your batch dry and crumbly. The only thing I could think of is maybe use less oats. Stir in 3 cups of oats (instead of the extra 3/4 cup) and that will make them even more gooey. But may take a little longer to set up.
      Thank you so much for stopping by and letting me know how they turned out for you! xo

    what happens if you use the quick oats? Have you every tried substituting the oats with a cereal like rice crispies or corn flakes?

    • says

      I haven’t tried using the quick oats in this recipe. (I always have old fashioned oats on hand.) You could possibly try the quick oats, it would just absorb the liquid much faster in this recipe and have a different texture. Corn flakes on the other hand, loose their crisp when adding to the moisture. I would highly recommend keeping with the rice crispies. Thank you for stopping by with your questions! Have most amazing weekend! 🙂

    I’m so excited that I found this recipe! I “may” have made these bars three times in the past two weeks 🙂 The only changes that I made was I replaced 1/4 c of butter with coconut oil and I only use 1 c of chocolate chips for the top. Delicious!
