Chocolate Chip Cookie Bars

These cookie bars are the chocolate chip version of my super popular M&M’S Cookie Bars. These cookie bars are always a reader favorite, especially the Christmas Cookie Bars! They are easy to make, absolutely delicious and always a hit at parties and potlucks. For this recipe, I use a combination of mini semi sweet chocolate chips and milk chocolate chips. The pecans are optional, and can be left out or substituted with walnuts.

Lining the Pan

Line the pan with a sheet of foil and spray with non stick cooking spray. Once the cookie bars have cooled, they will easily lift out of the pan and peel off the foil. Then you can cut the cooled chocolate chip cookie bars into squares.

Can I use parchment paper instead of foil?

You can use parchment paper, it’s just not as easy to use as the foil. The cookie dough is very thick and trickier to spread on parchment paper. The foil is wrapped around the edges of the pan, so it stays in place when spreading the dough. It’s also easier to lift the cooled cookie bars out of the pan with the foil.


Cookie Bars

Cookie bars are my favorite because they can easily serve a crowd. Plus you skip the rolling or scooping step. In a 9×13 pan, I generally cut the bars into 18 bars for a generous serving size. This is the size I would use for a stand alone dessert, a bake sale or packaging gifts during the holidays. For feeding a crowd at a potluck or party, I would cut the 18 squares in half to make a total of 36 servings, which is equal to a single cookie size.

 What pan should I use for chocolate chip cookie bars?

Traditionally, I have used a 9×13 glass Pyrex dish to bake these cookie bars and it works great. I have noticed that they bake up a little more evenly in a 9×13 metal cake pan  so I have switched to using those. Either will work.
