Ingredients
- 1 1/2 cups all-purpose flour
- 1 teaspoon ground cinnamon
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 lb unsalted butter, at room temperature
- 3/4 cup sugar
- 3/4 cup packed dark brown sugar
- 2 large eggs, at room temperature
- 2 teaspoons vanilla extract
- 2 1/2 cups rolled oats (not quick cooking)
- 6 ounces semi-sweet chocolate chips
Directions
- Position oven rack in the lower third of the oven; preheat oven to 350°; butter and flour a 9×13 inch pan; set aside.
- In a bowl, whisk the flour, cinnamon, baking soda, and salt until combined; set aside.
- In a big bowl, cream the butter, sugar, and brown sugar using an electric mixer on medium speed; continue beating until pale brown and thick, about 7 minutes.
- Add the eggs one at a time, allowing the first to be thoroughly incorporated before adding the second.
- Scrape down the sides of bowl as necessary; after beating in the second egg for 1 minute, stir in the vanilla.
- Using a wooden spoon or rubber spatula, stir in the oats and chocolate chips until combined.
- Then stir in the flour mixture just until incorporated (do not beat).
- Spoon batter into prepared pan, pressing it gently into the corners with your fingers.
- Bake for 30 minutes, until the top is lightly browned and a pick comes out clean.
- Set pan on a wire rack to cool for at least 30 minutes.
- Cut blondies into 24 pieces while they are still in the pan; carefully remove with an offset spatula.
- Serve immediately or let cool completely before covering with plastic wrap for storage at room temperature.
