How to Make Irish Oatmeal Cookies
This delicious and easy-to-make recipe comes together in just a few simple steps. Just follow these instructions and you will have an easy snack recipe in no time at all.
Step 1: Make the oatmeal
Begin by boiling oats and water in a saucepan. Once boiling, set heat to low and allow to cook for about 15 minutes. If it is getting too dry, add water one tablespoon at a time. You do not want it too liquid, this is just to cook the oats/soften them.
Step 2: Cream together butter and sugar
In a large bowl, cream together butter and brown sugar.
Step 3: Add the egg and oats
Once creamed, add egg yolk and mix some more. Add cooked oats and combine.
Step 4: Sift the dry ingredients
In a separate bowl, sift together flour, baking powder and salt. Slowly add to wet ingredients and combine until a dough forms.
Step 5: Chill the dough
Wrap the dough in plastic wrap and place in freezer for about 15 minutes.
Step 6: Prepare a cookie sheet and preheat the oven
Line a baking sheet with parchment paper and preheat oven to 350 degrees F.
Step 7: Shape and place on the prepared pan
Once the dough is done chilling, remove from freezer and roll into spheres, about 1 ¼ inch in diameter. Place on lined baking sheet, leaving about 1 ½ inches between each one.
Step 8: Bake the cookies
Bake for 12 to 15 minutes and allow to cool completely on a wire rack before serving.
