My mom always called these no-bake cookies. I love this recipe because it is so easy to make. My kids love the chocolate and peanut butter mix just like I did when I was their age and still do today. The combination is a classic. I like Edmund K's idea about keeping the crunchy peanut butter. I think that would add a bit of texture that would prove to be very welcoming. I plan to find out this weekend. Thanks!

This sounds like a really tasty recipe, but the title is a bit misleading. I've always thought anything named Mississippi Mud would incorporate marshmallows or marshmallow cream into the recipe. So, when I try this out, I'll see about adding some marshmallows to the mix. I'm also a fan of the crunchy style peanut butter, so I might substitute that as well. Looking forward to giving this a go.

These are so good. I had only ever made these into drop cookies before. I had never thought of making them into bars before. I never heard them called Mississippi Mud though. They have always been unbaked cookies. My husband always called them minute cookies cause they don't take long to make. Weather seems to play a factor in how well they set up as cookies. Bars might not have that problem.

These look so good, although they are more of a bar than a cookie. No-bake recipes are fantastic, especially in the summer when you don't want to turn the oven on. These are a great alternative to granola or snack bars and with the oatmeal and peanut butter, they are both filling and healthy! These are great to have on hand when you're on the go on weekends or with after school activities!

this sounds like the no bake cookies I used to make when I was a kid. They are so easy, and such a great mix of chocolate, peanut butter, and oatmeal. These will be tasty with a glass of milk.

We call them FUDGIES, have been made in my family for 50 years or more, all 5 generations still love them. Could not be any easier, and everyone enjoys them.

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.
