Gluten-Free Iced Oatmeal Cookies

While my go-to cookie is a chocolate chip cookie, I must admit that I enjoy a good oatmeal cookie from time to time. These cookies are soft in texture and have an intense flavor (you can taste the brown sugar). I think any cookie lover will enjoy these wonderful cookies. I filled them with raisins, but of course, you could always use chocolate chips. The icing adds a wonderful touch of sweetness, although it is a totally optional addition.

  • 1.5 cups powdered sugar, sifted 180 grams
  • 1/4 tsp vanilla extract
  • 2 Tbsp milk


  • Preheat oven to 350ยบ F. Line 2 baking sheets with parchment paper. Set aside.
  • In a bowl attached to your standing mixer (or use your handheld mixer), beat together butter, granulated sugar and brown sugar. Add eggs one at a time until well incorporated.
  • Add vanilla, cinnamon, salt and baking soda. Mix well. Then slowly add flour and continue mixing until well combined.
  • Fold in oats and raisins.
  • Add rounded spoonfuls of batter to prepared baking sheets about 2" apart. 
  • Bake for 10-12 minutes or until edges are slightly browned.
  • Allow cookies to cool on baking sheet for 5 minutes and then transfer to a wire rack to cool completely. 
  • To prepare icing mixture, combine powdered sugar, vanilla and milk in a bowl and mix well until smooth. If mixture is too thick, add a tiny splash of milk. If it's too thin, add more powdered sugar.
  • Once cooled, use your spoon to drizzle the icing over the cookies (while they are on the wire rack so the icing can flow off and not puddle around the cookies). Allow icing 1-2 hours to set before enjoying (if you can wait that long).


When drizzling the icing over the cookies, place a piece of parchment paper under the wire racks to catch the drip off.
