I love cookies that remind me of  kitchen sink cookies. A little bit of this and a little bit of that. These cookies are filled with oats, crispy cereal, and chocolate chips. These cookies have a bit of everything and the combination is absolutely delicious.


  • Granulated sugar- You can’t make great tasting cookies without sugar.
  • Light brown sugar- Brown sugar adds flavor and helps to keep the cookies moist.
  • Butter- Always use unsalted butter so that you can control the salt in the recipe.
  • Eggs- The eggs do not need to be room temperature when making these cookies.
  • Vanilla- Always use real vanilla. It gives the best flavor.
  • All-purpose flour- Use all-purpose flour but self-rising flour works too.
  • Baking soda- Baking soda is a must in cookies.
  • Salt- Salt helps to bring out the flavor in baked goods.
  • Baking powder- If you are using self rising flour, you do not need baking powder.
  • Old-fashioned oats- You want to make sure that you are using old fashion oats and not quick oats.
  • Crisp rice cereal- This is cereal like Rice Krispies
  • Chocolate chips- You can use semi sweet or milk chocolate chips.

Can I Use Quick Oats?

When you are making these Rocky Mountain Cookies, you want to use old fashion oats. You want to avoid using quick cooking oats. They will cook to fast in the cookies and it will not give the desired effects.


Rocky Mountain cookies should be stored at room temperature and will last for about 2 weeks. You want to make sure the cookies are stored in an airtight container.
