Every so often I crave a straightforward cookie: not too sweet, not heavily spiced — just the simple goodness of oatmeal and carrot. This is my grandmother’s old-fashioned oatmeal cookie recipe, preserved without adding cinnamon or nutmeg because grandma was allergic. The result is an authentic, mellow cookie that lets the oats and carrots shine.
Ingredients

This recipe keeps the ingredient list short so the oatmeal and carrot flavors can stand out. There’s no cinnamon in the classic version, but you can add it later if you prefer a carrot-cake twist. If you don’t have carrots, shredded zucchini (with peel left on) is an acceptable substitute and will add a nice color.

Substitute Old-Fashioned For Quick-Cooking Oats?
Yes. Old-fashioned oats can be used in place of quick-cooking oats for most baking recipes. If you prefer a finer texture and a more uniform cookie shape, pulse old-fashioned oats briefly in a food processor or blender. If you don’t have a processor, you can chop them with a knife or use them as-is — the cookies will still be delicious, just a bit heartier.
Substitution for Baking Powder
If you run out of baking powder, you can make a quick substitute. For each teaspoon of baking powder, mix ½ teaspoon cream of tartar, ¼ teaspoon baking soda and ¼ teaspoon cornstarch. Use that mixture in the same amount called for by the recipe.

Substitution for Baking Soda
If you don’t have baking soda, baking powder can substitute in a pinch. Use three times the amount of baking powder for the required baking soda. For example, if the recipe calls for ½ teaspoon baking soda, replace it with 1½ teaspoons of baking powder.
Variations and Add-ins
These cookies are a great base for experimentation. Here are a few ways to vary the recipe:
- Coconut: Swap the walnuts for shredded coconut for a tropical twist.
- Raisins: Add raisins or golden raisins to give the cookies a carrot-cake-like flavor.
- Pecans: Replace walnuts with chopped pecans for a richer nutty taste.
- Cinnamon: If you want a spicier cookie, add 1 teaspoon cinnamon and ¼ teaspoon nutmeg. A light cream cheese frosting turns them into a mini carrot cake treat.

Equipment
- Medium mixing bowl
- Large mixing bowl
- Baking sheets
- Parchment paper or cooking spray
- Wire rack
Ingredients
- 150 grams (about 1¼ cups spoon-and-fill) all-purpose flour
- 1 cup quick-cooking oats
- ½ teaspoon salt
- 1 teaspoon baking powder
- ¼ teaspoon baking soda
- ½ cup (1 stick) unsalted butter, softened
- ½ cup packed light brown sugar
- 1 teaspoon vanilla extract
- 1 large egg
- ½ cup chopped walnuts
- ½ cup raw, shredded carrot (about 1 large or 2 medium)
- Cooking spray or extra parchment paper for shaping
Instructions
- In a medium bowl, whisk together the flour, oats, salt, baking powder and baking soda until evenly combined.
- In a large bowl, beat the butter, brown sugar and vanilla until creamy.
- Add the egg to the butter mixture and mix until combined.
- Gradually add the flour mixture, about half a cup at a time, mixing well after each addition.
- Stir in the chopped walnuts and shredded carrot until distributed throughout the dough.
- Cover the dough and refrigerate for one hour to firm up.
- Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper and lightly spray if desired.
- Roll dough into 1-tablespoon balls and place 2 inches apart on the prepared sheets. For uniform cookies, place a second spray-coated parchment sheet over the dough balls and gently press with a glass to slightly flatten, then remove the top sheet.
- Bake for 8–10 minutes, or until the edges are just lightly golden.
- Remove from oven and transfer cookies to a wire rack to cool completely before storing. Makes about 24 cookies.
Notes: The total time assumes baking a single sheet at a time. If your oven can handle multiple sheets at once, you will finish sooner. This recipe scales easily for cookie exchanges; double or triple as needed.

Measurement tip: When possible, weigh dry ingredients like flour for best accuracy. If you don’t have a scale, stir the flour lightly and use the spoon-and-fill method to avoid packing too much flour into the measuring cup. Too much flour can make baked goods dry and crumbly.
