Peanut Butter Chocolate Chip Bars

Whenever there is an opportunity to bake and share with other people, I am one of the first to say "yes". We had a bake sale at our office this week to raise money for a charity our company encourages us to donate to each year.

So, I pulled out a cookbook that I just knew would have a great recipe in it, Rosie's Bakery - All-Butter, Fresh Cream, Sugar-Packed No-Holds-Barred Baking Book. How can you go wrong with a title like that? I like making bars for bake sales because you can cut them into any size and you can easily make enough without spending hours in the kitchen.

I had all the ingredients on hand to make the Peanut-Butter Chocolate Chip Bars. The recipe is so simple to make and turns out so moist and chewy!

I allowed My Boys to each try a piece before I packaged them up and they were a huge hit! Even for My Youngest who claims to not like ANYTHING with peanut butter in it. Not sure how he missed it because the flavor is definitely there, they taste just like peanut butter cookies with soft chocolate chips hidden inside.

  • 1 1/3 cups plus 1 tablespoon plus 1 teaspoon all-purpose flour
  • 2 teaspoons baking powder
  • 1/8 teaspoons baking soda
  • 1/4 teaspoon salt
  • 8 tablespoons (1 stick) unsalted butter, at room temperature
  • 1/2 cup smooth peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup plus 2 tablespoons (lightly packed) light brown sugar
  • 1 teaspoon vanilla extract
  • 2 large eggs, at rooom temperature
  • 1 cup semi-sweet chocolate chips


  1. Preheat oven to 350 degrees. Lightly grease an 11x7-inch baking pan with butter or vegetable oil.
  2. Sift the flour through salt together in a medium-sized bowl and set aside.
  3. Using an electric mixer on medium-high speed, cream butter through vanilla until light and fluffy. Stop the mixer to scrape the bowl with a spatula.
  4. Add the eggs one at a time and beat on medium speed until partially blended after each addition. After the last addition, beat until blended.
  5. Add the dry ingredients to the batter and mix with a spatula until the flour is absorbed. Then mix on low speed until blended.
  6. Add chocolate chips and blend for several seconds. Spread the batter in the prepared pan. Bake the bars on the center oven rack until the center is lightly golden and slightly puffy - between 25 and 30 minutes. The center will drop when removed from the oven, creating the chewy texture.
  7. Allow the bars to fully cool before cutting them into squares.

Makes 12 bars.

These look really great, and I love that there is slightly more brown sugar than sugar, which is usually a sure sign the dessert is going to be delicious and moist!
