Ingredients
1 cup butter (227 g), room temperature
1 cup light brown sugar (220 g), packed
1/2 cup granulated sugar (100 g)
2 large eggs
2 teaspoons vanilla extract
1/2 teaspoon salt
1 teaspoon baking soda
1 teaspoon baking powder
1 1/2 cups all-purpose flour (188 g)
2 cups old-fashioned rolled oats (170 g)
2 cups chocolate chips (340 g, semi-sweet, milk, or mixed)
Instructions
Preheat oven to 350°F (180°C).
Prepare a 9×13-inch baking pan with cooking spray or parchment paper.
In a large bowl, beat butter, brown sugar, and white sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in vanilla extract.
In a separate bowl, whisk together flour, baking soda, baking powder, salt, and rolled oats.
Add the dry mixture to the butter mixture and stir gently until combined.
Fold in the chocolate chips.
Spread the dough evenly into the prepared pan, pressing into the corners.
Bake for 25–30 minutes, until golden brown and edges are set.
Cool completely before slicing into squares or bars.
Notes
Use old-fashioned rolled oats for the best chewy texture.
Cream butter and sugars thoroughly to keep bars soft.
Measure flour with the spoon-and-level method to avoid dryness.
Remove bars from the oven while the center looks slightly soft they’ll set as they cool.
Let bars cool fully before cutting to get neat, clean edges.
Mix semi-sweet and milk chocolate chips for balanced sweetness.
Add chopped nuts for crunch if desired.
Line the pan with parchment paper for easy removal.
Store in an airtight container for 3–4 days at room temperature.
Freeze for up to 3 months and rewarm in the oven before serving.
