Wonderfully soft and chewy, Irish Oatmeal Cookies are made with some of Ireland’s tastiest ingredients! Irish steel cut oatmeal keeps its chewiness while baking and adds a nutty flavor. Irish butter provides rich, creamy taste and golden syrup adds the warmth of toffee.
Why you’ll love this recipe
This year I am celebrating St. Patrick’s Day with Irish Steel Cut Oats Cookies. They aren’t flashy, but they are so delicious, that I am tempted to say they are my favorite cookies yet.
The Irish oatmeal is chewy and nutty, the Irish butter is creamy and rich, and the Lyle’s Golden Syrup imparts a toffee warmth.
Whenever I bake a cookie in which the flavor of butter is the star, I always use Kerrygold Irish butter. (This is NOT a sponsored post.) Irish butter has a higher fat content than American butter. You can taste the difference in cookies like shortbread and these Irish Oatmeal Cookies.
If you aren’t familiar with Lyle’s Golden Syrup, I urge you to find it and try it. I buy mine at World Market or in the pancake syrup aisle at the supermarket.
Golden syrup is a sugar syrup made from sugar cane or sugar beet and is popular in the UK. It has the consistency of corn syrup or honey (both of which can be used as substitutes) but has a toffee flavor all its own.
Irish Oatmeal Cookies with a cup of tea make every day a bit of a celebration! This taste of Ireland is a delicious care package or cookie jar treat!

My experience with this recipe
With St. Patrick’s Day around the corner, visions of all things Irish (or an American interpretation of all things Irish) dance through our heads. It turns out that most of the green sprinkled goodies (and most definitely the green tinted beer) are more a result of America’s tendency to create drinking celebrations, than Irish tradition.
Numerous years ago, my daughter and I went on a trip to London that coincidently started on St. Patrick’s Day. We were excited to spend the holiday in the UK. We imagined some kind of “traditional” celebration.
Information on the internet seemed to indicate that a parade and a variety of Irish cultural events were scheduled. Something was apparently lost in the translation between expectation and reality.
We couldn’t locate the cultural events and the very short “parade” was mostly a line of buses and flat-bed trucks sponsored by trade unions and filled with members of those unions getting a head start on their afternoon pint or two or three of beer/stout.
American’s aren’t the only ones who like a drinking celebration.
I prefer Irish Oatmeal Cookies.
