After Several Failed Attempts, Here Is Katalin´s Take on How to Turn Chocolate Chip Cookies into Cookie Bars

While turning chocolate chip cookies into irresistible cookie bars might seem as easy as pressing any batch of cookie dough into a pan, there's a bit more to it if you want flawlessly satisfying results. Trust me, I've tried it that way, and it didn't work out well at all! Instead, I ended up with greasy, unappealing cookie bars that were far from what I had in mind.

After several rounds of trial and error, I found that the secrets to creating the ideal cookie bar texture while preserving that classic chocolate chip cookie flavor intact were 1. adding an extra egg, 2. adding corn starch, and 3. adding a bit more flour (vs. my chocolate chip cookie recipe) to keep it sturdy while balancing the flavors. That sounds easy once you know it, right?

So, if you're ready to bring the convenience of chocolate chip cookies to a tasty new level, keep reading!

Ingredients

You only need a few simple pantry staples, such as butter, sugar, flour, eggs, and chocolate chips to make this recipe. For a printable recipe card with exact ingredient quantities, visit the original Chocolate Chip Cookie Bars recipe at Spatula Desserts.

We start with a cookie dough

Before beginning the cookie dough mix, ensure your butter (unsalted butter only) and egg are at room temperature. See my guide on softening butter quickly for tips on how to do so without using a microwave. To quickly bring the egg to room temperature, stick it in a bowl of warm water for 5-10 minutes.

Preheat your oven to 175°C / 350°F (without the fan setting), and prepare a 9-inch / 23 cm brownie pan. Lightly grease the pan with a small amount of oil, then line both the bottom and sides with parchment paper.

Using an electric hand mixer, cream the softened butter and sugar (both the granulated and dark or light brown sugars) for a few minutes until the mixture becomes light and fluffy. Add the room-temperature eggs and vanilla extract and mix just until combined.

In a separate bowl, sift in the all purpose flour, cornstarch, salt, and baking soda. Salt is a key ingredient that enhances and balances the flavors of the other ingredients, so don't leave it out!

Use a rubber spatula to gently fold this dry mixture into the wet ingredients until just combined. Finish by folding in the chocolate chips.

Then bake it in a brownie pan to turn it into cookie bar

Transfer the cookie bar dough to the prepared baking pan. Use an offset spatula to spread it evenly and smoothly. It is highly recommended to add more chocolate chips on top.

Bake at 175°C / 350°F for approximately 30 minutes, until the edges appear baked and the center is golden brown and slightly gooey (but not raw). Avoid overbaking, as the cookie bars will continue to firm up as they cool.

Let the bars cool completely in the pan, then slice, serve, and enjoy!

What to do with leftovers

To experience the absolute best chocolate chip cookies bars, I recommend enjoying them the same day you bake them. However, if you have leftovers, you can keep them fresh in an airtight container at room temperature for 2-3 days.

To freeze the cooled, sliced bar cookies, wrap each in foil, using parchment paper between layers to prevent sticking. Then, place them in a freezer-safe bag or container and freeze for up to one month. When you're ready to enjoy them, let them thaw at room temperature. I recommend warming them for a few seconds in the microwave to melt the chocolate again!

Ingredient Substitutions If You Must

For a vegan version of these chocolate chip cookie bars, consider using one of these egg substitutes and high-quality vegan chocolate chips. For butter-free cookies, you can use my chocolate chip cookies without butter recipe.

If you don't have or prefer not to use brown sugar, you can use my chocolate chip cookies without brown sugar or one of these many brown sugar substitutes.

Instead of all-purpose flour, you can use a blend of low-protein flour (i.e., pastry flour) and high-protein flour (i.e., bread flour). For gluten-free cookies, you can switch to gluten-free flour. For more information about the different types of flour and how to use them in baking, refer to my flour guide.

However, baking is a science that requires precision and accuracy, so making ingredient substitutions can be a challenge. Substituting ingredients will also require adjusting the quantities and ratios of other components in the recipe, which I can't guarantee will result in the same taste or texture.

My Expert Tips For Making Chocolate Chip Cookie Bars

For the best results and rich flavor, always opt for high-fat, high-quality ingredients, such as high-fat butter (I use 83% European-style butter) and high-quality semi sweet chocolate chips (i.e.Callebaut or Lindt). Lower-quality chocolate may turn greasy when melted, so investing in good ingredients makes a difference!
When preheating, consider setting the oven at 20°C / 68°F higher than the recipe calls for to account for the heat loss when opening the oven door. Once the cookie bars are in, lower the oven to the correct temperature for baking.
Mix the ingredients only just until combined. Overmixing the dough can result in a crumbly texture.
Consider reducing the baking time and slightly underbaking the cookies for a softer, gooier texture. Whatever you do, do not overbake, as you may end up with dry, crumbly cookies!
Although you may be tempted to dive in as soon as they're done baking, allow the bars to cool completely before slicing. Cutting them too soon may cause them to fall apart.

What Equipment To Use

For the most precise measurements, a digital scale is a must. A digital oven thermometer is also helpful to ensure your oven maintains the ideal temperature during baking.

An electric hand mixer makes combining the wet ingredients a breeze, but you will need a rubber spatula to gently fold the wet and dry ingredients together without overmixing.
