Iced Oatmeal Cardamom Cookies with Butterscotch Glaze

Soft, chewy oatmeal cookies spiced with warm cardamom and topped with a rich butterscotch-flavored icing. The margarine creates an exceptionally tender texture while the cardamom adds an unexpected aromatic twist to the classic oatmeal cookie. Perfect for potlucks, bake sales, or when you want to impress with a familiar yet sophisticated treat. The butterscotch icing sets these apart from ordinary oatmeal cookies, creating a bakery-style finish that stays soft and sweet.

Tips

Tip 1

Use margarine instead of butter in the cookie dough for the softest, most tender texture as recommended in the recipe.

Tip 2

Frost cookies while slightly warm so the icing sets with a smooth, bakery-style finish that won't crack.

Tip 3

Space cookies only 1 inch apart as they don't spread much during baking due to the oats and margarine.
