INGREDIENTS
¾ cup butter, melted
½ cup granulated sugar
½ cup lightly packed brown sugar
1 large egg
1 large egg yolk
1 tsp vanilla extract
1 tsp baking soda
¼ teaspoon salt
1 ½ cups all-purpose flour
1 cup quick oats or old-fashioned rolled oats
2 cups chocolate chips or chocolate chunks
INSTRUCTIONS
1. 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.
2. 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.
3. Add the flour, oats and chocolate chips and mix until evenly combined.
4. 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).
