I have always loved classic oatmeal cookies. There is something wonderful about a cookie that has its roots in a breakfast grain. It may be a bit indulgent, but I firmly believe an oatmeal cookie is a justified way to start a day!
Ingredients for Classic Oatmeal Cookies:
These cookies are fantastically easy to make and rely on cupboard staples:
- Butter - unsalted butter, softened at room temperature. I've also made these with melted butter and the recipe will still work. The batter will be softer and the cookies will spread more when baking.
- Sugar - a combination of superfine granulated sugar (or caster sugar) and firmly packed light brown sugar (muscovado). You can substitute dark brown sugar for the light brown if you like a darker cookie and a stronger molasses-y flavour.
- Egg - you only need one for these cookies to act as the binding agent, bringing it all together. This should be at room temperature for best results.
- Vanilla - my favourite ingredient! I firmly believe in splurging on good quality vanilla as it really adds to any recipe. My preferred vanilla is usually Nielsen-Massey, but there are other suppliers of excellent quality vanillas, if you shop around!
- Flour - you can use all purpose flour or plain flour in this recipe.
- Baking soda
- Ground cinnamon
- Ground nutmeg
- Oats - the star of the show! I use rolled oatmeal and have a soft spot for Quaker Oats as a family favourite when I was growing up.
Making the Classic Oatmeal Cookies
This is a simple one bowl cookie recipe. Begin by creaming the butter and sugars together. Then add the egg and vanilla. Follow this with sifting in the flour, baking soda, salt and spices. And finally stir through the oats.
Once your dough is ready, dollop this out onto baking sheets lined with either parchment paper or silicone baking mats and bake in a preheated 375°F oven until going golden at the edges.
Tips and Tricks
Just a few of my main recommendations for this recipe:
- If you have a stand mixer available, it is definitely worth pulling it out for oatmeal cookie dough. The batter, especially once you add the oats, is extremely thick and liable to break a spatula (I should know - I've broken a few!).
- My cookie scoop is probably my favourite kitchen appliance! You can also use a spoon, but the scoop is super useful for cookies as well as cupcakes or anything that needs a bit of dolloping.
- To help the cookies spread a bit, gently press each with a dampened palm right before baking. The water on your hand will avoid you sticking to the cookie dough.
- If you've used a dark brown sugar, the cookies may look darker as they bake, but 12 minutes is usually a good estimate for how long each batch will take.
- Leaving the cookies to cool on the tray for a few minutes before placing on a wire rack helps give them a chewy finish. It also makes it easier to move them once they've cooled down a bit!
FAQs for Oatmeal Cookies
Oatmeal cookies can keep for several days in a cookie jar or other sealed container at room temperature.
Yes, absolutely! Freezing cookies is super simple.
The best way is actually to freeze the cookie dough before it is baked. Dollop this into balls of dough and flash freeze on a lined baking tray. Once firm, transfer to a ziploc bag and keep in the freezer for up to three months.
These frozen dough balls then become cookies on demand direct from the freezer whenever you need them! No need to defrost, simply increase your baking time by about 5 minutes (normally - keep an eye for traditional signs of doneness)
You can also freeze the cookies once baked for up to three months.
Yes of course! In fact, I have made this exact recipe using vegan substitutes in the past. Simply use a vegan non-dairy butter alternative in place of the butter and replace the egg with ¼ cup vegetable or other flavourless oil. The oil will help to bind the ingredients.
The vegan version of these cookies may produce a slightly runnier batter dependent on the type of non-dairy butter used, but otherwise they will bake quite similarly.
Another alternative for the egg, is to use peanut butter instead of oil. This will produce an oatmeal peanut butter cookie, and the taste of the peanut butter will come through in the finished product. This might work for you dependent on your preferences, but I'd not necessarily recommend if you're not aiming for something peanut-y!
