Molly Beth's Chocolate Peanut Butter Oatmeal Cookie Bars

Chocolate Peanut Butter Oatmeal Cookie Bars combine creamy peanut butter, rolled oats, and chocolate chips into a moist, slightly gooey baked bar with a tender but sturdy texture. The bars have a balanced sweetness with a buttery richness and chocolate-ply pockets throughout. They are baked just until edges set, retaining a soft center.

Description

This recipe mixes softened butter, brown and granulated sugars with egg and peanut butter to create a rich base. Flour, baking soda, and salt provide structure, while old-fashioned oats and chocolate chips add texture and chocolate flavor. After spreading the dough evenly in a baking pan, it is baked at 350°F until the edges just begin to brown and the center remains slightly jiggly, ensuring the bars stay tender and chewy.

The texture of these bars resembles large cookies with a moist, gooey center balanced by crisp edges. Chocolate chips throughout provide bursts of chocolate flavor, complementing the peanut butter and oats. Baking time can be adjusted slightly for firmer or softer results.

These bars are suited for snacks, casual desserts, or when a quick handheld treat is desired. They pair well with milk or coffee and can be enjoyed warm or cooled.

Notes recommend milk chocolate chips but allow for substitution or combination with semi-sweet chips. Using a 9x9 pan will produce thinner bars and slightly shorter baking times. Cooling before cutting helps bars set properly.

Ingredients

Servings
  • 1/2 /2 cup butter softened at room temperature
  • 1/2 /2 cup brown sugar
  • 1/2 /2 cup granulated sugar
  • 1 egg room temperature
  • 1/2 /2 heaping cup peanut butter creamy
  • 1/2 /2 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 /2 teaspoon baking soda
  • 1/4 /4 teaspoon salt
  • 1 cup old-fashioned oats rolled oats
  • 1.5 .5 heaping cups chocolate chips

Instructions

  1. Pre-heat the oven to 350° F. Line an 8x8 pan with parchment paper.
  2. In a large mixing bowl, using an electric mixer, combine the butter, brown sugar, and granulated sugar. Add egg, peanut butter, vanilla extract, flour, baking soda, and salt until just combined. Stir in the oatmeal and chocolate chips.
  3. Spread the dough evenly in your pan. Top with additional chocolate chips as desired for looks - and, chocolate! Bake for 18-22 minutes until edges are set and begin to just turn golden brown. The middle will be slightly jiggly, but that's what you want. The bars are like cookies in that you don't want them overbaked, with a slightly gooey center. If you prefer them more well done, bake for an additional 5-7 minutes.
  4. Place the pan on a cooling rack and let it cool at least 15-20 minutes before serving so they have time to set up. The longer you let them cool, the more set they will be. However, they're just so so good when enjoyed warm that I often will eat them warm with a fork instead of "bar form".
  5. The bars are excellent served with ice cream or on their own. Store any leftovers covered at room temperature.

Notes

  • Milk chocolate chips are recommended, but semi-sweet or mixed chips also work well.
  • A 9x9-inch pan can be used for thinner bars, reducing baking time slightly.
  • Allow bars to cool 15-20 minutes before cutting so they set properly, though they can be enjoyed warm.
