These oatmeal cookie bars are soft, chewy, and perfect for sharing! Made with pantry staples and packed with chocolate chips, they’re an easy, crowd-pleasing treat you’ll want to make again and again.
Preheat oven to 350°F (175°C). Line a 9x13-inch pan with parchment or lightly grease.
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar. Add the eggs and vanilla; mix until smooth.
Stir in the flour, baking soda, and salt until combined. Fold in the oats and chocolate chips.
Spread evenly into the prepared pan. Bake 22–26 minutes, or until the center is set and top is golden. A toothpick should come out with a few moist crumbs.
Let cool completely in the pan before cutting into bars.
Notes
For the best texture, use old-fashioned rolled oats. Quick oats can make the bars softer and less chewy.
Feel free to swap or combine chocolate chips with other mix-ins like nuts, dried fruit, or butterscotch chips.
Be sure to let the butter cool slightly so it doesn't start cooking the eggs or melting the chocolate.
Optional: Add 1/2 teaspoon ground cinnamon to the dry ingredients for a cozy flavor twist. This is especially nice if adding nuts or dried fruit.
Bars will slice more cleanly once completely cooled. Chill briefly for especially neat edges.
Store in an airtight container at room temperature up to 4 days.
To freeze, wrap bars tightly and freeze for up to 3 months. Thaw at room temperature.
