Low Carb Iced Oatmeal Cookies are a nostalgic favorite reimagined gluten-free and lower in carbs.

These Low Carb Iced Oatmeal Cookies have about 3g net carbs per cookie while retaining the classic iced oatmeal cookie flavor.
Remember those old-fashioned iced oatmeal cookies from the store? I loved that they didn’t have raisins and that sweet icing on top. The royal-style icing makes them feel celebratory — and I still enjoy it.
These lower-carb cookies use gluten-free rolled oats and a moderate amount of almond flour to deliver the familiar taste and texture without the heavy carb load of a traditional recipe. They are not grain-free, but they are gluten-free and surprisingly low in net carbs despite the oats.

These were a helpful bake while pantry supplies were limited — and both my husband and teen son loved them.

Some Helpful Process Shots
Low Carb Iced Oatmeal Cookies
Ingredients
Cookies:
- 1 ¼ cup Blanched Almond Flour
- 1 cup Gluten-Free Rolled Oats
- 1 teaspoon Baking Powder
- 1 teaspoon Cinnamon
- ⅛ teaspoon Nutmeg (optional)
- ⅛ teaspoon Sea Salt
- 7 tablespoons Butter, softened (room temperature)
- 2 large Eggs
- ⅔ cup brown-style sweetener (Lakanto Golden or Swerve Brown)
- 1 teaspoon Vanilla Extract
Icing:
- 6 tablespoons erythritol confectioners sweetener (e.g., Swerve)
- ¼ teaspoon Vanilla Extract
- ½ teaspoon lemon juice
- 1 ½ tablespoon Heavy Cream
Directions
- Preheat the oven to 350°F (177°C). Line two cookie sheets with parchment paper or silicone liners.
- In a large bowl, combine the gluten-free rolled oats, almond flour, baking powder, cinnamon, nutmeg (if using), and sea salt. Set aside.
- In a mixing bowl, cream the softened butter with the eggs and vanilla using an electric mixer until smooth and creamy.
- Add the dry ingredients to the wet ingredients and mix until fully combined.
- Drop rounded tablespoonfuls of batter onto the prepared sheets about 2 inches apart, as the cookies will spread.
- Gently flatten each mound with the back of a spoon or your hand. Bake 12–16 minutes until cookies are just set and the edges are golden. Remove and cool completely on the pans before moving.
- While the cookies cool, whisk the icing ingredients together in a medium bowl until smooth.
- Brush a thin layer of icing over the tops of the cooled cookies with a pastry brush. Allow the icing to set for several minutes, then serve.
