Oatmeal Chocolate Chip Cookie Bars

Yield: 24 Bars (9X13-inch pan)

Prep Time: 20

Cook Time: 20

Total Time: 40

Ingredients

¾ cup (170 g) butter, melted
½ cup (106 g) granulated sugar
½ cup (106 g) lightly packed brown sugar
1 large egg
1 large egg yolk
1 teaspoon vanilla extract
1 teaspoon baking soda
¼ teaspoon salt
1 ½ cups (213 g) all-purpose flour
1 cup (100 g) quick oats or old-fashioned rolled oats
2 cups (340 g) chocolate chips or chocolate chunks

Instructions

Preheat oven to 350 degrees F. Lightly grease a 9X13-inch baking pan with cooking spray or line with parchment and lightly grease parchment and set aside.
In a large bowl, add the butter, granulated sugar, brown sugar, egg, egg yolk, vanilla, baking soda and salt, and mix by hand or with an electric mixer until well-combined.
Add the flour, oats and chocolate chips and mix until evenly combined.
Press the batter evenly in the prepared pan and bake for 18-20 minutes. Don't over bake! These bars are best under baked just a tiny bit.

Notes

Butter: to take it up a notch, try browning the butter first. Amazing! Also, I always use salted butter.

Doubling: this recipe doubles great to fit in a half sheet pan (11X17-inch rimmed baking sheet).

Update: the original bar recipe posted in 2008 called for 1 3/4 cups flour, but I've long since cut the flour amount back to 1 1/2 cups for softer, chewier bars.
