If you’re craving something sweet, cookies are a good option, especially if chocolate is involved! And cookies are even better if they’re double chocolate. But when cookies support a great cause, it’s the best-case scenario.

For the fourth year in a row, fellow food blogger Julie organized an event called the Good Cookies Food Bloggers’ Valentines Event to support Cookies for Kid’s Cancer. (Last year, I shared my small batch bakery style chocolate chip cookie recipe for this event.)

Cancer is the leading cause of children’s disease-related death in the U.S. Right now, 40,000 children here are actively battling cancer. And less than 4% of the National Cancer Institute’s budget goes to childhood cancer. This is why Julie got involved. Last year, she raised $76K through this event! That is absolutely amazing, right?!

The goal is to raise $3,000 in donations. The three event sponsors (Dixie Crystals, MediaVine, and OXO) have each agreed to match the donations up to $3,000! You can read more about this event on Julie’s blog here or donate (edited: this event ended and we met our goal!).

A Note For My Readers: I have so much respect for Julie for her incredible work supporting such a great cause. And thank you, Dear Readers, for reading and considering donating. Please do what you can, even if it’s just helping to spread the word about childhood cancer awareness. xoxo, Faith

Inspiration For This Double Chocolate Chip Cookies Recipe

I first came up with this recipe a few years back when I lived in DC. Mike (my now ex-husband), asked me for a homemade version of the Subway Double Chocolate Chip Cookies and that’s exactly what I came up with. I can’t believe it took me so long to share the recipe! These cookies are his absolute favorite and I still send a box of them to him for his birthday every year.

If you like the Subway Double Chocolate Chip Cookies, you’ll love these!

These cookies are slightly crisp outside with a chewy texture inside. They have rich chocolate flavor, thanks to the use of cocoa powder in the dough.

I use a little bit of espresso in the dough, which helps pull out the complex flavor notes of chocolate. Don’t skip the molasses, it adds depth and helps make these cookies chewy.

And of course the double chocolate part of these cookies comes from the fact that these chocolate cookies are studded with chocolate chips!

Chocolate Chocolate Chip Cookies Ingredients

Ingredients Explained

In this section I explain the ingredients and give substitution ideas where applicable. For the full recipe (including the ingredient amounts), see the recipe card below.

  • Flour – Use regular all-purpose flour.
  • Unsweetened cocoa powder – This adds rich chocolate flavor. Use natural cocoa powder here, not “Dutch processed”.
  • Baking soda – The leavening agent in this cookie that helps us achieve the perfect texture.
  • Salt – To create a balanced flavor profile and season the dough so the cookies aren’t bland.
  • Unsalted butter – For rich flavor and crispy-outside, chewy-inside texture.
  • Sugar – Use regular granulated white sugar here.
  • Egg – An egg adds moisture and helps create the texture we’re going for.
  • Egg yolk – Helps create the rich, chewy texture of these cookies.
  • Blackstrap molasses – Adds rich notes of molasses and caramel, and helps make these cookies chewy.
  • Pure vanilla extract – Enhances the flavor and aroma, and helps pull out the nuances of chocolate.
  • Instant espresso powder – Helps bring out the flavor notes of chocolate.
  • Semisweet chocolate chips – Cocoa powder in the dough + chocolate chips = double chocolate chip cookies! Instead of chocolate chips, you can use chocolate chunks (or a chopped chocolate bar for puddles of chocolate).

How to Make Double Chocolate Chip Cookies

These cookies are as easy to make as regular chocolate chip cookies! However, it’s important to give the dough time to chill in the fridge for at least one day. This helps create the perfect flavor and texture.

  1. Make the dough. Whisk together the flour, cocoa powder, baking soda, and salt in a medium bowl and set aside. Beat together the butter and sugar, and then beat in the egg, egg yolk, molasses, vanilla, and dissolved espresso. Stir the dry ingredients into the wet and fold in the chocolate chips.
  2. Chill. Cover the dough and refrigerate for at least 1 day, but up to 3 days.
  3. Scoop. Preheat oven to 335F and let dough rest at room temperature 45 minutes. Line 2 half sheet pans with silpat liners.
  4. Bake. Use a 1/4-cup scoop to measure out the dough and roll it into balls. Bake 6 cookies per half sheet pan one pan at a time until golden along the outside, but still a touch doughy in the center, about 13 to 14 minutes. Cool before removing from the trays.

Storage

I store these cookies the same way I store other types of drop cookies, such as regular chocolate chip cookies. Layer them cookies between wax paper in an airtight container and store at room temperature for up to 1 week.

Tips For the Best Chocolate Chocolate Chip Cookies Recipe

  • Using a combination of granulated white sugar + molasses gives us more control of the result than using brown sugar. (If you’ve ever opened a bag of brown sugar that seemed more dry and clumpy than normal you’ll know exactly what I’m talking about!) However, you can use 1 1/3 cups of lightly packed light brown sugar instead of the white sugar and molasses.
  • These cookies are decadent and quite large! If you prefer, you can make them half this size (using 2 tablespoons of dough per cookie) and adjust the bake time accordingly.

Frequently Asked Questions

What does an extra egg yolk do in cookie dough?

The extra egg yolk in this cookie recipe adds fat and moisture. It results in richer, fudgier cookies with the perfect chewy texture.

Why do we melt and slightly cool the butter for these cookies?

Melted butter helps create cookies that are fudgy and chewy inside and crispy outside. The butter should still be hot when you mix it with the sugar (to help the sugar dissolve), but the mixture shouldn’t be hot when you add the eggs (otherwise you run the risk of scrambled eggs).

Note that this cookie recipe calls for chilling the dough for at least 1 day or up to 3 days. This ensures that these cookies will not flatten or over-spread even though the butter was melted.

What makes cookies chewy?

If you’re looking for cookies that are chewy inside and crispy outside, you found them! Here we stack a few techniques for no-fail results every time.

Ingredients make a big difference. To start, the right ratio of fat to sugar to flour is crucial. And we melt the butter so the sugar dissolves. We also add molasses. An extra egg yolk helps too!

Additionally, the method is important. Don’t skip the 1 day chill time, and be sure to take the dough out of the fridge 45 minutes before you scoop it. Lastly, don’t over-bake!

Follow this recipe and you’ll end up with the perfect chewy/crispy cookie texture.
