Oatmeal Chocolate Chip Cookie Bars

These bars combine the chewy texture of oats with the rich sweetness of chocolate chips, held together by a buttery cookie base. The recipe balances melted butter, sugars, and eggs to create a soft, tender consistency that contrasts with the slight chewiness from the oats. Baking briefly prevents over-drying, resulting in bars that remain moist. This format is practical for serving a crowd or slicing for snacks, offering a straightforward alternative to traditional drop cookies.

Description

Oatmeal Chocolate Chip Cookie Bars bring together the familiar flavors of a classic cookie in a convenient bar format. Melted butter mixed with both granulated and brown sugars forms a sweet, rich foundation. Eggs and egg yolk provide moisture and tenderness, while the addition of baking soda and salt aids in texture and flavor balance. Quick or rolled oats add chewiness and hearty texture. Chocolate chips dispersed throughout melt into pockets of sweetness.

The dough is pressed evenly in a parchment-lined pan and baked at 350°F for just under 20 minutes to avoid over-baking, ensuring a soft center with slightly firm edges. This baking method yields bars that hold together well when sliced, ideal for packing or sharing.

These bars serve well as a portable treat, dessert, or sweet snack. Their composition allows for easy doubling to suit larger groups, fitting into a half-sheet pan as needed. The recipe's flexibility accommodates browning the butter for a deeper flavor or adjusting flour quantity to affect softness.

To maintain their texture, do not over-bake, as the bars benefit from a slight under-baking for chewiness. Using salted butter is recommended, and for best results, prepare with parchment to prevent sticking.

Ingredients

Servings
  • ¾ cup butter melted
  • ½ cup granulated sugar
  • ½ cup brown sugar lightly packed
  • 1 large egg
  • 1 large egg yolk
  • 1 teaspoon vanilla extract
  • 1 teaspoon 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

  • Browning the butter before mixing enhances the flavor, providing a nuttier richness.
  • Salted butter is preferred for this recipe to balance sweetness effectively.
  • The recipe doubles well and fits a half-sheet pan (11x17 inches) for larger batches.
  • Reducing the flour to 1 1/2 cups from the original 1 3/4 cups results in softer and chewier bars.
  • Avoid over-baking; the bars should remain slightly under-baked for optimal texture.
