Chocolate Chip Cookie Bars for a Crowd

If there’s one dessert I can always count on to disappear fast at potlucks, church functions, or family gatherings, it’s Chocolate Chip Cookie Bars. They have all the flavor of classic chocolate chip cookies—but in easy, sliceable bar form that feeds a crowd without a lot of scooping, chilling, or multiple baking sheets.

These cookie bars are thick, soft, buttery, and loaded with chocolate chips in every bite. They’re baked in a half sheet pan, making them perfect for serving a big group with minimal effort.

Best of all? You mix everything in one bowl, spread it in the pan, and let the oven do the work.

Why You’ll Love These Cookie Bars

  • Perfect for a crowd – One half sheet pan makes a big batch
  • No scooping or chilling – Just spread and bake
  • Soft, chewy, and thick – With golden edges and a soft center
  • Totally customizable – Add nuts, different chips, or leave them plain
  • Easy to transport and slice – Ideal for potlucks and events

Perfect for Every Occasion

These Chocolate Chip Cookie Bars for a Crowd are my go-to when I need a reliable, homemade dessert that everyone loves. They’re easy, comforting, and always one of the first things to disappear from the table.

Whether you’re baking for a party, a church event, or just your own hungry family—this is one recipe you’ll come back to again and again.

Cookie sheet I use (half sheet size). I love this set of two that comes with a covers too!

Description

These Chocolate Chip Cookie Bars for a Crowd are my go-to when I need a reliable, homemade dessert that everyone loves.


Ingredients

  • 1 1/2 cups softened butter (3 sticks – I use salted)

  • 1 cup granulated sugar

  • 1 cup brown sugar

  • 3 large eggs

  • 1/2 tablespoon vanilla

  • 3 1/3 cups flour

  • 1/2 tablespoon baking soda

  • 1 teaspoon salt

  • 2-3 cups chocolate chips

  • 1 1/2 cups chopped nuts (optional)


Instructions

  1. Preheat the oven to 375°F. Line a half sheet pan (approximately 18×13 inches) with parchment paper or spray with nonstick spray. It is easier to spread the dough using the spray instead of parchment.
  2. Cream the butter and sugars together until light and fluffy.
  3. Add the eggs and vanilla and mix until smooth and fully combined.
  4. Mix in the dry ingredients: flour, baking soda, and salt. Stir just until combined—don’t overmix.
  5. Fold in the chocolate chips (and nuts, if using).
  6. Spread the dough evenly into the prepared half sheet pan. Use a spatula to smooth the top.
  7. Bake for 17-20 minutes, or until the top is lightly golden and the center is just set. Do not overbake—the center should still be soft.
  8. I found them easier to cut while slightly warm.
  9.  

Notes

These bars are easy to customize:

  • Swap some chocolate chips for white chocolate or butterscotch chips
  • Add M&M’s for a fun, colorful version
  • Try toffee bits or chopped pretzels for crunch
  • Drizzle with melted chocolate after baking for an extra-decadent finish

Tribute to my sweet Mom

I developed my love of cooking at an early age “helping” my Mom bake cookies, make dinner, and knead bread. She had quite the well of patience! She is the one that taught me about measurements, leavening agents, egg-washes, the basic white sauce, and numerous other mysteries of the kitchen!  I cherish the memories I have of learning to cook at her side. Thank you Mom! You instilled in me a respect for work as well as a joy in creating delicious things. I love you! xoxo
