Nana's Chocolate Chip Cookie Bars Recipe

These chocolate chip bar cookies were a standard in our house growing up. Mom often baked a batch for us to enjoy as lunch box treats and after school snacks. I still love to sample these chocolate chip squares warm from the oven with the melting chocolate chips - it makes me feel like a kid again.

Now that you've found an easy recipe for chocolate chip squares, it's time to begin to whip up a batch. Feel free to customize this recipe to make the chocolate chip bars you like best -- with nuts or without?

I prefer mine without nuts, just like how Mom used to make them. You can also experiment with different types of chocolate chips -- semi-sweet, milk chocolate, chocolate mint, dark chocolate, white chocolate, mini-chips, chocolate chunks -- the choice is yours.

I like making Nana's Chocolate Chip Bars with mini-chocolate chips best these days.

  • 1/2 cup butter, softened
  • 2 1/4 cups firmly packed brown sugar
  • 3 eggs
  • 2 3/4 cups flour
  • 2 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 1/2 teaspoons vanilla
  • 2 cups chocolate chips
  • 1 cup chopped nuts (optional)

Always remember to read the entire recipe to make sure you have all the ingredients on hand before beginning. There's nothing more frustrating than to begin mixing cookie bar dough only to discover you are missing a key ingredient that requires a trip to the market.

  1. Preheat oven to 350F degrees.
  2. Grease a 10x15-inch pan with cooking spray. If you prefer thicker chocolate chip cookie bars, like I do, use a 9x13 pan instead. When I last made them in a 9x13 pan they turned out about 1-inch thick and took just 30 minutes to bake.
  3. Combine the flour, baking powder, and salt with a whisk in a medium bowl. Set aside.
  4. Cream together the butter and sugar with an electric mixer in a large bowl until smooth and creamy.
  5. Beat in eggs and vanilla.
  6. Beat in the flour mixture a little at a time until well combined, but don't over mix.
  7. Stir in chocolate chips and nuts (if using).
  8. Spread the batter evenly into the prepared pan and bake for 20 to 25 minutes, until golden brown and a wooden toothpick inserted in the center comes out clean (avoiding chocolate pieces as they will be melty).
  9. Cool on wire rack.
  10. Cut into desired size bars.
  11. Store the cookie bars in the pan covered with foil or plastic wrap or remove them from the pan and place them in an airtight container. These chocolate chip cookie bars freeze well too.

Nana's Chocolate Chip Cookie Bar recipe makes about 35 cookie bars.
