How to Make Lump of Coal Bittersweet Chocolate Cookies
-
Preheat the oven to 350°F (175°C). This step is essential to ensure your cookies bake evenly, creating that perfect chewy center and crisp edges.
-
Cream together the cold unsalted butter, packed light brown sugar, and granulated sugars in a large bowl until smooth. This mixture should be light and fluffy, which helps the cookies rise beautifully.
-
Beat in the eggs, one at a time, then stir in the pure vanilla extract. This will add richness and depth of flavor to your cookie dough.
-
Whisk together the flour, black cocoa powder, baking powder, baking soda, instant coffee or espresso powder, and kosher salt in another bowl. This dry mix is crucial for achieving that signature bittersweet taste and perfect texture.
-
Gradually blend the dry ingredients into the creamed mixture. Mix just until combined, as over-mixing can lead to tough cookies.
-
Fold in the dark chocolate chips gently until evenly distributed throughout the dough, ensuring each cookie has gooey pockets of chocolate.
-
Scoop spoonfuls of the dough onto a lined baking sheet. Roll each mound in the extra granulated sugar before baking for a sweet, sparkly finish.
-
Bake for 10-12 minutes or until the edges are set but the centers remain soft. The cookies will continue to firm up as they cool.
-
Cool the cookies on the baking sheet for a few minutes before transferring them to a wire rack. This allows them to set perfectly without falling apart.
Optional: Add a sprinkle of sea salt on top for a delightful contrast to the sweetness.

Expert Tips for Lump of Coal Cookies
-
Room Temperature Butter: Ensure your cold butter is just a bit softened before creaming. It helps create a lighter dough and ensures even mixing.
-
Don’t Overmix: When combining dry and wet ingredients, mix just until incorporated. Overmixing can lead to tough, chewy cookies instead of soft, delightful Lump of Coal treats.
-
Chill the Dough (Optional): If time allows, chill your dough for about 30 minutes before baking. This can intensify the flavors and help maintain the cookie shape while baking.
-
Watch the Bake Time: Keep a close eye on those cookies! Remove them from the oven when the edges are set but the centers are still soft for that perfect fudgy bite.
-
Use Quality Chocolate: Opt for high-quality dark chocolate chips. The better the chocolate, the richer and more satisfying your cookies will be.
-
Extra Flavor Kick: Consider adding a pinch of cinnamon or a splash of almond extract for an unexpected twist that elevates the bittersweet profile.
Make Ahead Options
These Lump of Coal Bittersweet Chocolate Cookies are perfect for busy home cooks looking to save time! You can prepare the cookie dough up to 24 hours in advance; simply wrap it tightly in plastic wrap and refrigerate. This helps the flavors meld while also maintaining the dough’s freshness. If you want to plan further ahead, you can freeze the dough for up to 3 months. When ready to bake, scoop the chilled or frozen dough onto your baking sheets, roll in sugar, and add a couple of extra minutes to the baking time. This allows you to enjoy fresh, gooey cookies without the hassle of prep on busy days!

Lump of Coal Bittersweet Chocolate Cookies Recipe FAQs
What type of cocoa powder is best for this recipe?
I recommend using black cocoa powder for its rich, deep flavor that perfectly complements the dark chocolate chips. It gives the cookies their characteristic color and a gourmet touch. If you can’t find black cocoa, regular unsweetened cocoa powder will work too, but the color will be less intense.
How should I store leftover cookies?
Absolutely! Store your Lump of Coal cookies in an airtight container at room temperature for up to 3 days. If you’d like them to stay fresh longer, you can refrigerate them for up to a week, just be sure they’re well-wrapped to avoid drying out.
Can I freeze these cookies?
Yes! To freeze your cookies, first, place them in a single layer on a baking sheet without touching and freeze for about 2 hours. Once frozen, transfer them into a freezer-safe bag. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy some, simply reheat in the oven at 350°F (175°C) for about 5 minutes if frozen.
What should I do if the cookie dough is too sticky?
If your cookie dough is sticky, don’t worry! You can sprinkle a bit more flour onto your work surface, or add in a tablespoon at a time while mixing until it reaches a manageable consistency. A little stickiness is normal, but it shouldn’t be unworkable by any means.
Are these cookies suitable for people with nut allergies?
Yes! This particular cookie recipe does not include any nuts, making it a great option for those with nut allergies. However, always check the labels of your ingredients, especially for chocolate chips, to ensure they haven’t been processed in facilities that handle nuts. If you’re baking for someone with severe allergies, it’s safer to use brands that guarantee nut-free production.
