Classic Chewy Oatmeal Cookies de Yaz

Description

1. Adjust oven rack to middle position and heat oven to 375F. Line 2 baking sheets with parchment paper.
2. Whisk flour, salt, and baking soda together in a bowl.
3. Melt butter in 8-inch skillet over medium-high heat, swirling skillet occasionally. Continue to cook, stirring and scraping bottom of pan with heatproof spatula, until butter is dark golden brown and has nutty aroma, 1-2 minutes. Transfer browned butter to a large bowl, scraping skillet with spatula, and stir in cinnamon.
4. Whisk brown sugar, granulated sugar, and oil into browned butter until combined, in a glass bowl. Whisk in egg and yolk and vanilla until smooth. Using a wooden spoon or stiff rubber spatula, stir in the flour mixture until fully combined, about 1 minute. Stir in oats and raisins, if using, until evenly distributed (mixture will be stiff).
5. Scoop 3 tablespoons of dough at a time for each cookie. Space dough balls 2 inches apart on prepared parchment sheets, 10 per sheet.
6. Bake cookies, 1 sheet at a time, until edges are set and lightly brown and centers are still soft but not wet, 8-10 minutes, rotating sheet halfway through baking. Let cookies cool on sheet for 5 minutes, then transfer to wire rack with side metal spatula. Let cookies cool completely before serving.
