It doesn’t get more classic than oatmeal cookies. Try them with raisins — you might be pleasantly surprised!

Oatmeal cookies are a timeless favorite, simple and comforting. With just a few pantry staples you can make cookies that are chewy, aromatic, and full of texture. Raisins add little pops of sweetness and chew that complement the cinnamon and oats; if you prefer, swap them for chocolate chips, nuts, or sprinkles — the dough is versatile and forgiving.
I drifted away from raisins for a while, preferring chocolate chips or nuts when I was baking for company. Recently I went back to the classic and was reminded why these cookies are so enduring. Finding the raisins in the store felt like a small adventure, but it was worth it: the familiar flavor brought back memories and made the cookies shine.
These cookies are great whether you shape them by scoop and drop or press the batter into a pan for a bar-style bake. A cookie scoop gives consistent sizing, which helps with even baking and a neat presentation, but you can also freeform them for a rustic look. I often bake them on sturdy metal cookie sheets for the best, most even results.
This recipe has evolved over time. It’s the basis for other oat-based bakes I make regularly, and you can easily adapt it by swapping in whole-wheat flour or changing the mix-ins. As for the oats, either old-fashioned or quick oats will work — choose based on the texture you prefer. Old-fashioned oats give a more pronounced chew and visible oat texture, while quick oats yield a slightly smoother bite.
These oatmeal cookies also freeze very well. Bake a batch, let them cool completely, and freeze in a single layer before transferring to a container. Thaw at room temperature and you’ll still have a lovely cookie days or weeks later.
