I can’t take credit for this one.  It’s all grandma with these cookies!  This recipe comes from my grandmother, who was the ultimate cookie baker.  I’m so lucky to have her recipe, and you’re so lucky I’m sharing it with you!

What makes this recipe so special?

Grandma’s Oatmeal Cookies are made with shortening.  You cannot substitute butter for the shortening. Butter also has a lower melting point, which means that the fat melts at a lower temperature and the cookies will spread and flatten out faster during baking.  If you try to use butter, I fear that these cookies will turn into awful, flat disks instead of cookies.  My solution is to use butter shortening instead of plain shortening.  Baking cookies with shortening will make them more tender than crispy.

Grandma’s Oatmeal Cookies have plenty of cinnamon in them- one whole tablespoon!  I love a good cinnamon-infused oatmeal cookie.  Raisins and nuts are optional.  Grandma used to add them in, but I prefer them without.

What kind of oatmeal is best for cookies?

In oatmeal cookies, old-fashioned oats will give you a chewier texture, and quick oats will taste more like you ground up the oats a bit (slightly less chew, but still the same flavor). It’s really personal preference which one you like better for baking.  I suggest you use the old-fashioned oats for Grandma’s Oatmeal Cookies!

These are both a chewy and crunchy oatmeal cookie recipe.  I think you’ll find that everyone will rave about them.

Do you have to add baking soda to cookies?

Baking soda acts as a chemical leavener in these cookies, causing them to rise and spread slightly. It also influences the texture. If you forget to add baking soda to the cookies, they’ll likely be flat and somewhat hard.

    I followed the recipe and the cookies came out picture perfect. My only change would be to add more sugar , cinnamon and less salt. The cookies are not very sweet, which is fine , but the after taste is salt.

    I chose this 4 star recipe over the others which were 5 star and I’m glad I did. I give it 5 stars. Finally I’ve made a softer oatmeal cookie I like! (I’m 63) I used a 1/4th less sugar and added about 3 tablespoons of protein powder so we can eat these with no guilt. I also switched to half butter instead of all shorthening. (and my shortening is butter flavored)
