Wonderfully textured and chewy, Irish Oatmeal Cookies are made with some of Ireland's tastiest ingredients! Irish steel cut oatmeal keeps its chewiness while baking adding a nutty flavor and nubby texture. 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 oats are 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!
This is an overview of the instructions. The full instructions are in the recipe card below.
- In a large mixing bowl, whisk together flour, baking powder, and baking soda.
- In the bowl of an electric mixer, cream the butter and sugars until fluffy, then beat in the egg and golden syrup. Gradually mix in the flour mixture. Stir in oatmeal and toffee bits.
- Allow the dough to rest for 10 minutes so that the oats will absorb some moisture.
- Use a cookie scoop to place dough balls at least 2” apart on a parchment paper lined baking sheet.
- Bake for 12-15 minutes, at 350° F, until golden brown all over.
Store in an airtight container at room temperature for up to one week.

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.
Irish Oatmeal Cookies
- 1 cup all-purpose flour
- ¾ teaspoon baking powder
- ¼ teaspoon baking soda
- 7 tablespoons unsalted butter I use Kerrygold Irish butter, softened at room temperature for 10 minutes
- ⅓ cup white sugar
- ⅓ cup dark or light brown sugar packed
- 1 large egg
- 3 tablespoons Lyle’s golden syrup corn syrup or honey can be substituted but the flavor will be different
- 1 ¾ cups Irish steel-cut oats
- ½ cup toffee bits
- Preheat the oven to 350°. Line a cookie sheet with parchment paper.
- In a medium bowl, whisk to combine flour, baking powder, and baking soda.
- In the bowl of a stand mixer, beat butter and sugars until fluffy (about 3 minutes).
- Beat in egg and golden syrup.
- Gradually add flour mixture until incorporated.
- Stir in oats and toffee bits.
- Allow the cookie dough to rest for 10 minutes so that the oats will absorb some moisture.
- Use a cookie scoop to place dough balls at least 2” apart on the prepared baking sheet.
- Bake cookies for 12-15 minutes or until golden brown all over.
- Cool on the baking sheet for 5-10 minutes before transferring to a wire rack to cool completely.
- Store in an airtight container at room temperature for up to one week.
- The type of oat used is important. This recipe calls for steel cut oats for a very chewy, nut-like texture.
- Substituting old-fashioned oats (rolled oats) will create a less nutty texture and less chew.
- Quick oats or instant oats are not recommended as they will dissolve more during baking and create a soft, cake-like cookie.
- For variety, substitute the toffee bits with dark chocolate chips or golden raisins.
- Double wrap pairs of cookies (bottoms together) in plastic wrap.
- Fit snuggly into freezer weight zip lock bags or plastic storage containers.
