Preparation Time: 15 min

  • 1/2 cup milk

  • 1/2 cup peanut butter
  • 1 teaspoon vanilla
  • 3 cups rolled oats
  • pinch of salt

You haven't truly lived until you've made the delicious treats in our collection, 22 No-Bake & Easy Pie Recipes!


  1. Prepare a 7 x 11-inch baking pan by lining with parchment paper or foil, pressing into the corners and leaving an overhang of 2 inches on each long side.
  2. In a 1-quart saucepan over medium heat, stir together sugar, milk, butter, cocoa powder and salt and bring to a boil. Boil for one minute, stirring constantly. Remove pan from the heat and stir in peanut butter and vanilla and stir until completely smooth. Stir in the oats until well coated.
  3. Pour the mixture into the lined pan and use a spatula to push it into the corners and smooth the top.
  4. Refrigerate for 30 minutes then remove from the pan by lifting the paper out of the pan using the overhanging pieces. On a cutting board, use a serrated knife to cut through the cookies making 32 rectangular bars.
  5. Remove to a serving plate and store, covered, in the refrigerator if not serving right away.

Variation: Cookies may be spooned onto a wax paper-lined baking sheet in one tablespoon portions; this will make about 60 small cookies.

The combination of chocolate and oatmeal in this is perfect and chewy!

These bars melted in my mouth! Definitely for chocolate-lovers )

For those who love rich, peanut-buttery treats, these won't disappoint.

These were much better than I expected! I hadn't expected them to have such a soft texture, and I really loved that. They're different than your average cookie/cookie bar and would make such a fun addition to a party!

Simple and tasty, what could be better? I will be making this again when I get a craving for something sweet.

These were really delicious. They had great texture and flavor. A little on the sweet side, but I'd definitely recommend them if you're a dessert lover.

These were great. I don't eat a lot of desserts with oats, but these were really terrific.

mmmm!!! These cookies could be easily addicting! A little on the sweet side, though...might try using less sugar next time.

I'm not wild about peanut butter in my cookies, but these were pretty good. Next time I might try using chocolate hazelnut spread instead of the peanut butter.

I loved these! I could literally eat a whole plate full and still want more!

These are delicious! Taste resembles puppy chow with a more fudge-like texture. A little sweet for my taste though so I may cut the sugar a little bit.

This was really tasty! I could eat a bunch of these easily they were so good.

Anytime you can mix peanut butter and chocolate, I'm a fan!

These tasted just like puppy chow- but in a cookie form! I loved this light, tasty treat.

In my (recipe) book, peanut butter and chocolate make for one of the best flavor combinations out there. These bars are so delicious, it's hard not to keep eating them. The rolled oats make me feel a LITTLE bit better about eating them LOL, though they are not health food for real. Just a fun, easy dessert that tastes great!

Loved the combo of flavors! A sweet, but not too sweet, treat!

I loved the addition of peanut butter - it made the bars so much more flavorful. The oatmeal gave them a nice chewy texture. If you like really sweet desserts, you'll love these cookies.

It's hard to stop myself from grabbing a second bar!

I like to put them in a brownie pan. They stay moist longer. I cook mine until bubbles are just starting around the edge of the pan. Never a waste of ingredients.

You have to boil for 3 min. and work fast or they will set up on before you get them out of the pan. And it is a very good cookie.

I made these exactly by recipe and they are a waste of ingredients. They had a good taste, but never firmed up.
