Rocky Mountain Cookies

Such a delightfully simple cookie. But oh baby, are these ever worthy to grace the posts of Sugar Rush.

Think of a chewy, soft oatmeal chocolate chip cookie with light and crunchy Rice Krispies bubbling through every bite. I love the texture of these cookies. Thick and soft, crunchy and chewy…and so very simple to throw together.

They won’t last long, I can promise you that.

    These sound delicious! Can’t wait to try them but out of curiosity is this recipe already adjusted for areas of high elevation?

  2. Kelly Flores says:

    My daughter loves to bake. This recipe was featured on a Good Housekeeping article entitled 50 Most Delicious Cookies by State. She is baking through the list and has started a Facebook page for her baking adventures. We take the cookies she bakes to our local youth theater. Yesterday, we made these cookies. The kids LOVED them – they were a huge hit with all the teens and kids. A few Moms even asked me to share the recipe. Congrats!

  3. Jamie says:

    MEL – DO YOU KNOW THESE COOKIES ARE ON A GOOD HOUSEKEEPING LIST OF BEST COOKIES BY STATE? I think it actually had nothing to do with people in that state liking them. Some of the links are to places wanting to sell you cookies, but most are to recipes.
    I hope this leads lots of people to your site! I am thinking you have lived somewhere around the Great Lakes, and now you’re in Idaho. Maybe you have friends in Colorado who will especially appreciate this recipe and your site attached.

    Finally got around to trying a new cookie, and had never had Rice Krispies in a cookie, so curiosity pulled me to this recipe. It was delicious. I loved the extra texture from the oats and cereal together. Plus they baked up beautiful round and thick. I used a 1 TB cookie scoop and it made 4 dozen. Thanks for something new to add to our cookie rotation. Your recipes simply never fail.

  5. Mydeerbambie says:

    This is real good treat! I love them. Made 37 cookies and ate 15 of them in 2 days (there goes my diet! Lol!) i added some grinded cheerios since i dont have enough rice krispies and they are still superb! Thanks for this wonderful recipe and cant wait to try another one! – the peanut butter and oatmeal cookies πŸ™‚

  6. Venessa says:

    Hi there! How many cookies does this recipe (and what size cookie – 1, 2, or 3 Tbl scoop)? I’m part of a cookie exchange coming up, and I need to make dough for over 120 cookies!

  7. Mel says:

    Rachel – sorry, I don’t understand what you are looking for. Another cookie recipe?

  8. rachel says:

    Mel where did your chocolate chip, oatmeal, with coconut flakes and dark and light brown sugar? Am I blind?

  9. Joan says:

    Love the cookies and the rice krispies are a nice addition.

  10. Mel says:

    Tracey – probably about 2-3 dozen.

  11. Tracey says:

    Just wondering if you know about how many cookies this recipe makes. I’m considering this recipe for a cookie exchange, but I have to take 3-4 dozen cookies! Thanks so much!

  12. Nan says:

    I made these yesterday- I had about half a package of Heath toffee chips so added them also. I like to make balls instead of drop cookies so your recipe made 4 and a half dozen golf sized balls that baked perfectly. I just tasted a couple of crumbs but I can tell they are good. I’m off to volunteering soon and they will be eaten quickly I am sure. Thanks!

  13. Dena says:

    Made these tonight. Seemed like they needed a longer cooking time in my oven. But, my husband raved about them, so that’s what’s important. Just wish I could try all these wonderful recipes of yours. Unfortunately they’re not on my diet list. Do you have any “healthy” recipes? πŸ™‚

  14. Kellie says:

    Hi there,

    Just made these cookies today for the first time… followed the directions exactly… they taste pretty good, but don’t look like yours in the picture! πŸ™ Any ideas on why not? I live in Utah, and I just have a regular oven (not convection). The cookies are flat and kind of “lacy” looking and fall apart easily. πŸ™ What do you think?

    BTW, LOVE your website; I get lots of recipes from here. Keep up the good work!

    • Mel says:

      Kellie – It’s hard to know exactly what went wrong but my guess is that it is something related to altitude – when I used to live in Utah, I often had to add a couple tablespoons of extra flour if my cookies were turning out flat like you said yours were. It could also be related to overly soft butter – that can make cookies bake up flat, too. Hope that helps a little!

  15. […] Hence the name, “As Good As Jamie Cookies”.Β  However, the other name for them is ‘Rocky Mountain Cookies’. Β  and as much as I like that name, too..I think I’ll stick with the name I came up with for […]

  16. NaDell says:

    I added Heath chips since I was all out of chocolate chips and they were delicious.
    The dry cookie trouble above was probably because of not softened butter. My dough was the same way, but I just formed them into little doughballs with my hands. I’m always too impatient to wait for the butter to soften. =) The kitchen aid does pretty well at breaking all the butter up evenly.
    I liked hearing the famous snap, crackle, and pop as I pulled them out of the oven I love this recipe!

  17. Melinda says:

    5 stars! My son said these are his new favorite cookie. I followed Kara’s suggestion of increasing the salt and adding cinnamon – the cinnamon really adds a special touch, and the rice krispies are a such a fun surprise. Can’t wait to try more of your recipes!

  18. Birgitta says:

    I never expected the extra crunch in this cookie to be so good! I added 1 tsp of cinnamon because I love oatmeal and cinnamon together. Yet again, another delightful recipe! πŸ™‚

  19. juliann says:

    I didnt go for the cinnamon chip variation, I was too chicken, but I really loved these cookies. They were really light and I felt less guilty because of the oatmeal and the cereal dispersed some of the butter and sugar so you ate less of the bad stuff…..least that is what I told myself when I ate about 2 dozen myself πŸ™‚ When I make these again I will for sure take them out just as they get slightly brown, some where a little too crisp, but if you pop them in the microwave for 10 sec. they get nice and chewy! You cant waste a single cookie, when I finally bake something.

  20. Kensi says:

    I made these in the 9×13 pan and they turned out great! Everyone loved them! Thanks and hope you had a very Merry Christmas!!

  21. Tricia says:

    I made them, and I liked them. I can’t say I loved them, but they were all right. They were better when cooled completely. I was surprised that I got not just texture from the rice crispies (which I liked) but also a little flavor (the thing that kept me from loving them.)

    So, the tip on greasing the pan or using parchment, that’s a good tip. Totally.

  22. juliann says:

    I am about to make these and found cinnamon chips in my pantry….I wonder how those would taste instead of the chocolate chips? I bake maybe twice a year so I dont know if I want to risk it!

  23. Amanda Good says:

    I am planning on giving out cookie dough as a gift this year, (gotta love the line, ” ’cause everyone can use come dough this time of year”). Does the dough freeze well to cook later? Looks Yummy!

  24. KeithsKelly says:

    Very good cookie! Made a trial batch to see if they would be added to the annual cookie trays (I add a new wildcard recipe each year) and they are a keeper! Will be making many, many batches of these this week!

  25. Kristine says:

    These look like a delicious twist on traditional oatmeal chocolate chip cookies!

  26. Brittany says:

    We have a recipe like this at our house too! The recipe calls for either rice krispies or corn flakes. I personally prefer the corn flakes. But they are my FAVORITE cookies! YUM

  27. Kim in MD says:

    I’ve never had Rice Krispies in a cookie…I bet they are fabulous! I can’t wait to try this recipe! πŸ™‚

  28. grace says:

    i had forgotten about these, which is a shame, because those rice krispies are such an unexpected and welcome addition. good stuff.

  29. Tessa says:

    Thick, soft, crunchy, chewy… sounds perfect!

  30. Janette says:

    I made these cookies tonight and they have really good flavor. I love the crunch of the rice krispies, however; my cookie dough was really crumbly and the second batch would not stick together. I added some milk to the dough and they turned out much better. Did I do something wrong when I mixed the dough together?

    • Mel says:

      Janette – was your butter soft enough? Hmmm…I’m not sure what would have gone wrong but I’m glad that you were able to rescue the dough with the milk!

  31. Kara Larson says:

    I have a recipe just like this I was going to post over on my blog soon, it’s my favorite cookie! But mine has 1 tsp salt (which I really like) 1 tsp cinnamon and only 1 cup of oatmeal, they are thinner I think than yours, and crunchy! That brown sugar and krispies along with the cinnamon make them addictive!

    I think I need to make a batch just for me!

  32. Abby says:

    I love the surprise ‘crunch’ of Rice Krispies in cookies!

  33. kathleen says:

    Mel, these look delish! I’m bookmarking them right now πŸ˜‰

  34. Kensi says:

    Oh, I forgot to ask… can I bake these in bar form? In a 9×13 pan?

    • Mel says:

      Kensi – I’m not sure since I haven’t tried it…I think it’s worth a try. I’d probably use a 9X13-inch pan and bake them for about 18 minutes to start with (check often!).

  35. Kensi says:

    These look yummy! I am going to make them for my husband’s birthday next week. He is a cake hater and always requests cookies for his birthday! πŸ˜€ Thanks for the recipe!

  36. Kira says:

    A new cookie always gets my attention. My two year old loves to help dump things into the mixing bowl, so he would love to help with these! I have learned beyond helping with that part there isn’t much I can actually consider to be help from him. But he loves to cook, well bake really.
