This recipe makes a huge batch, about 4 dozen to be exact. That might be enough to feed the whole neighborhood.

Or just me.  🙂

If you generously fill the sandwich cookies with filling, you may run a little short, but the cookies are quite good eaten plain.

The cookies are just a little soft and chewy and flavored with cinnamon and nutmeg. They are made with shortening instead of butter which really helps them hold their shape and gives them a wonderful soft texture.

I love to pile them high on a plate and watch them disappear.

    I have made these countless times. The recipe is perfect. If you prefer a butter flavor, use butter flavored Crisco.
    I have passed on this recipe to several friends. I have even made them for bakery boxes I have sold.
    Thank you for the recipe!

      You can, but it will change the texture of the cookies. Shortening makes cookies that are a little more soft and tender and they don’t tedn to spread quite as much as cookies made with butter.

    Oatmeal sandwich cookies were always a favorite of mine as a kid! These are making me so nostalgic!

    Oh my goodness, these look so soft and delicious! And marshmallow creme filling sounds amazing!! Definitely loving these. <3

  4. I was so obsessed with the Little Debbie version of these when I was a kid. They used to sell them at our school and me and my friends would take turns once a week buying them for each other. But this homemade kind looks a billion times better! I’ve wanted to make these for a long time. I can’t wait to give it a try!

  5. Chewy and soft cookies are great on their own and perfect for a sandwich cookie! These are such a special treat! Hope you have a wonderful Mother’s Day, filled with good things tomorrow. : )

  6. This batch would only feed me…the neighbors will have to wait! These look beyond delicious, Christin, and I love that marshmallow-y filling! Have a wonderful Mother’s Day. 🙂
