I'm not lying when I tell you that my cookie bar recipes have changed my life. This M&M Cookie Bar recipe went ultra-viral and changed the trajectory of my business for the better! I'm also a hugggee fan of these crazy indulgent Peanut Butter Cookie Bars and these Lemon Cookie Bars for a super light and refreshing treat!

Why You'll LOVE This Recipe

Quick & Easy Preparation: This recipe is made with simple ingredients you already have on hand and requires just one bowl and a whisk. Mixing all the ingredients in one bowl without a mixer results in a faster prep time. Plus, you skip the tedious rolling process of normal cookies by baking them in bar form!

Chewy Texture: These chocolate chip cookie bars have the chewiest, fudgiest texture that stays soft and moist for days!

Customizable: You can easily add your favorite mix-ins like nuts, dried fruits, crushed candy pieces, marshmallows, or even different types of chocolate chips for variety.

Ingredients

  • Unsalted Butter: You'll melt your butter for flavor and moisture in every bite! Using melted butter also makes this a no-mixer recipe!
  • Light Brown Sugar & Granulated Sugar: Both sugars work together for flavor, moisture, and structure.
  • Eggs: Two eggs at room temperature add structure and chewiness.
  • Vanilla Extract: Vanilla extract rounds out the flavor of these cookies.
  • All Purpose Flour: All purpose flour, measured properly, creates soft and chewy cookies.
  • Baking Powder & Baking Soda: Together, both of these leavening agents give these cookies their rise and create gorgeous, thick domes!
  • Salt: Salt enhances the flavor and brings out sweetness.
  • Chocolate Chips: I use a combination of mini chocolate chips, regular chocolate chips, and large chocolate chips inside and on top of the dough.

Step by Step Process

STEP 1: Preheat your oven to 350 degrees Fahrenheit and line a 9x13 inch glass baking pan with parchment paper for clean removal after baking.

STEP 2: In a large bowl, use a whisk to stir melted butter, light brown sugar, granulated sugar, room temperature eggs, and vanilla extract together until smooth and fully combined.

STEP 3: Pour all purpose flour, baking powder, baking soda, and salt into the dough. Use a rubber spatula to mix the dry ingredients into the wet until all flour pieces disappear into the batter.

STEP 5: Transfer the cookie dough to your prepared 9x13 inch dish and press the dough into the pan evenly. Push additional chocolate pieces into the top of the dough.

STEP 6: Bake the cookie bars for 23-27 minutes or until the edges look light golden brown, the tops look slightly pale and just barely turning golden in color, and the centers look slightly soft and shiny.

Frequently Asked Questions

Can I add mix-ins?

Yes! Don't be afraid to experiment with different add-ins like nuts, dried fruits, candy pieces, or marshmallows for added flavor and texture. Add the extra mix-ins when you add the chocolate chips.

How do I know when cookie bars are done baking?

The bars are done when they turn light golden brown around the edges. A toothpick or cake tester inserted into the center comes out with some moist crumbs but no wet batter.

Can I make these bars ahead of time?

Yes, cookie bars are great for making ahead! Store them individually wrapped in cling wrap in the freezer for up to 4 months and thaw at room temperature or warm them in the microwave or in the oven at 350 degrees Fahrenheit until desired heat is reached.

Expert Tips

  • Use room temperature eggs, as they incorporate better into the dough. If you forget to take them out in advance, place them in a bowl of warm water for 3 minutes.
  • Use the correct-sized baking pan. A 9x13-inch pan is the standard for this recipe, and I recommend using a glass pan.
  • Before baking top the dough with additional chocolate chips for an elevated look and extra gooey chocolate in each bite.
  • Be cautious not to overbake, as doing so can result in dry and cakey bars. Start checking a few minutes before the recommended baking time since all ovens are different.
  • Allow the cookie bars to cool in the pan for about 30 minutes before lifting them out using the parchment paper overhang. This helps them set and makes for easier slicing.
  • Use a sharp knife to get clean, even slices. Wiping the knife with a warm, damp cloth between cuts can help achieve neater edges.

Storing

Allow Them to Cool: Before storing, make sure the cookie bars have completely cooled to room temperature and any chocolate because the chocolate will smear.

Wrap or Cover: You can cover the entire dish with aluminum foil, plastic wrap, or a fitted lid. If you've cut the bars into individual pieces, place them in an airtight container, resealable plastic bag, or wrap them individually in cling wrap.

Storing: These chocolate chip cookie bars can be stored at room temperature in a cool, dry place for up to 4 days. If your kitchen is particularly warm, or if you'd like to extend their shelf life, you can refrigerate the cookie bars for up to a week.

Freezing: For longer storage, you can freeze the bars by wrapping them individually in plastic wrap or aluminum foil and then placing them in an airtight container or a resealable freezer bag for up to 4 months. Thaw at room temperature or warm in the microwave or at 350 degrees Fahrenheit to get an even chewier texture.

Description

Indulge in pure cookie bliss with these Chocolate Chip Bars- crafted for ultimate convenience and decadence. With no need for a mixer and requiring just a single bowl, these chewy, buttery bars loaded with gooey chocolate chips promise effortless baking, irresistible flavor in every bite, and endless customization options!


Ingredients

Scale
  • 1 cup (220g) unsalted butter, melted
  • 1 cup (240g) light brown sugar, packed
  • ½ cup (105g) granulated sugar
  • 2 large eggs (100g), room temperature
  • 2 teaspoons vanilla extract
  • 3 cups (420g) all purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 ½ teaspoons salt
  • 2 cups (360g) chocolate chips of choice


Instructions

  1. Preheat your oven to 350 degrees Fahrenheit and line a 9x13 inch glass baking pan with parchment paper to ensure the cookie bars come out of the pan cleanly after baking.
  2. In a large bowl, use a whisk to stir melted butter, light brown sugar, granulated sugar, room temperature eggs, and vanilla extract together until smooth and fully combined.
  3. Pour all purpose flour, baking powder, baking soda, and salt into the dough. Use a rubber spatula to mix the dry ingredients into the wet until all flour pieces disappear into the batter.
  4. Use a rubber spatula to mix in the chocolate chips.
  5. Transfer the cookie dough to your prepared 9x13 inch dish and press the dough into the pan evenly.
  6. Push additional chocolate chips and/or chunks into the top of the cookie dough.
  7. Bake the cookie bars for 23-27 minutes or until the edges look light golden brown, the tops look slightly pale and just barely turning golden in color, and the centers look slightly soft and shiny. A toothpick inserted into the center of the cookie bars should come out with just a bit of batter on it, as the cookie bars will continue to cook in the pan as they cool.
  8. Allow the cookie bars to fully cool before slicing and storing. Store in an airtight container, tightly covered, or individually wrapped at room temperature for up to 4 days, in the fridge for up to a week, or in the freezer for up to 4 months.

Notes

Parchment Paper: Line the pan with parchment paper and leave an overhang on the sides for easier removal and slicing after baking. You'll be able to lift the bars out for slicing without having the bars stick to the pan.

Chocolate Chips: Use a variety of flavors and sizes of chocolate chips for the best look, flavor, and texture. Save some to press additional chocolate pieces into the top of the dough before baking for a more elevated look.

Bake Time: To avoid overbaking cookie bars, start checking for doneness a few minutes before the recommended baking time and remove them from the oven when the edges are light golden brown and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
