These easy oatmeal cookies are a quick treat made in one bowl. They bake up perfectly every time with a buttery brown sugar flavor, crisp edges and a soft, chewy center.
Preheat the oven to 350°F. Line a baking sheet with parchment paper or a silicone mat.
Cream 1 cup butter, 1 cup brown sugar and 3/4 cup granulated sugar in a large mixing bowl. Add 2 eggs and 2 teaspoons vanilla then mix until combined.
Add 2 1/3 cups flour, 1 teaspoon salt, 2 teaspoons baking soda, 1/2 teaspoon baking powder (and cinnamon if desired). Stir just until combined. Then mix in 2 cups oats.
Use a medium cookie scoop and scoop onto the prepared baking sheets. Bake for 8 minutes, or until the edges are just light golden brown (the centers should look a little underdone). Take them out a little early for softer cookies and bake them a little longer for crispier cookies.
Let cookies rest on the pan for 2 minutes and then transfer to a cooling rack.
Notes
If I have molasses on hand I love adding 1-2 teaspoons. Mix in 1 cup of raisins, chocolate chips or butterscotch chips. Use unsalted butter (recommended). If using salted, cut the added salt down to about 1/4 teaspoon or skip it altogether, since the butter already brings salt and amounts vary by brand.Storage: Store in an airtight container up to 3 days. Adding a slice of white bread to the container helps keep them soft. Freeze baked cookies up to 3 months, or freeze raw dough balls (flash freeze until firm, then bag) and bake from frozen, adding a couple minutes to the time.Less spread: This has been retested and brown sugar reduced to 1 cup so the cookies hold their shape while baking. If you prefer sweeter cookies, use 1 1/4 cups brown sugar, but know that they will spread more.
