These thick and chewy homemade oatmeal raisin cookies are the ultimate recipe! Learn how to make these deliciously soft, buttery cookies with simple ingredients.
In the bowl of a stand mixer fitted with the paddle attachment, cream butter and brown sugar at medium speed until fluffy (about 3-4 minutes), scraping the sides of the bowl periodically. Add egg and vanilla extract; beat well.
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
While the mixer is on low speed, gradually add the flour mixture just until combined. Fold in the oats and raisins. Cover and refrigerate for 1-2 hours.
Preheat oven to 350 degrees F. Line baking sheets with silicone mats or parchment paper.
Using a 4-teaspoon spring-loaded scoop, drop dough onto prepared pans. Place the cookie dough about 2 inches apart.
Bake until cookies are lightly browned, but still slightly soft (about 12 minutes). Let cool on pans for 3 minutes. Remove from pans and let cool completely on wire racks.
