The Best Oatmeal Cookie Bars
Description
This recipe begins by browning butter to develop a nutty flavor that enhances the depth of the cookie bars. The butter is mixed with light brown sugar and granulated sugar, then combined with eggs, milk, and vanilla extract to create a moist batter. Dry ingredients including flour, baking soda, salt, cinnamon, and rolled oats are folded in carefully to maintain texture. Dark chocolate chunks add richness and a contrasting texture.
The batter is spread into a prepared pan and baked until the edges turn golden and firm while the center remains chewy. After cooling for at least an hour, the bars are sliced, and flaky sea salt can be sprinkled on top to enhance the chocolate’s sweetness and provide a subtle savory note.
These bars offer a balance of chewy and slightly crisp textures with the warm spice of cinnamon, making them a satisfying treat for snack time or dessert. The inclusion of milk and browned butter distinguishes the flavor and texture from typical oatmeal cookies.
Ingredients
- 2 butter unsalted, melted, 8 ounces (1 cup
- 1 cup light brown sugar packed
- 1/2 cup granulated sugar
- 2 egg large plus 1 egg yolk, at room temperature
- 2 tablespoons milk
- 1 tablespoon vanilla extract
- 1 all-purpose flour 2/3 cups
- 1 teaspoon baking soda
- 3/4 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 2 cups rolled oats
- 1 dark chocolate 1/4 cup chopped, or your mix-in of choice
- 1 teaspoon sea salt flaky, optional
Instructions
- Preheat oven to 350 degrees (F). Line an 9x13-inch baking pan with parchment paper or aluminum foil. Spray lightly with non-stick spray and set aside.
- In a saucepan over medium heat, melt the butter, then continue to cook it, stirring occasionally, until golden brown. Keep an eye here, you don't want burnt butter! Remove from heat and scrape the butter into a large heat proof mixing bowl.
- Whisk in both sugars and mix until well combined. Stir in the vanilla. Then add in the eggs and egg yolk, beating until combined. Stir in the milk.
- Using a rubber spatula, add in the flour, baking soda, salt, cinnamon, and rolled oats, mixing until just combined. Finally, fold in the chocolate chunks. Scrape the batter into the prepared pan.
- Bake for 24 to 30 minutes, or until the edges are firm and golden. Press extra chocolate chunks on top of the warm bars, if desired.
- Cool in pan for at least 1 hour before cutting. Sprinkle with flaky sea salt before serving, if desired.
