These chocolatey chocolate chip shortbread cookies are extra delicious if you're a chocolate lover. They're made with black cocoa for an ultra-rich chocolate shortbread cookie, and then they're stuffed with dark chocolate chunks.
Hello, tall glass of milk! Meet your new best friend.
What you're going to love about this recipe
- The chocolate cookie dough is rich dark chocolate with the deep dark flavor of an oreo cookie with the buttery texture of shortbread.
- You can mix in chocolate chips or chocolate chunks if you want to, or you can bake this up without any mix-ins at all.
- The cookie dough freezes well, so you don't have to bake a huge batch. You can freeze the dough and have cookies on demand all year long.
What you'll need
- Unsalted Butter. Use European-style unsalted butter, which has a higher butterfat content than American butter.
- Sugar. Granulated sugar. Superfine sugar is a good choice here because it melts into the butter more quickly.
- Salt. Always use Kosher or fine sea salt for baking.
- Egg yolks. Egg yolks help to refine this dough and give it a more tender crumb.
- Vanilla.
- All-purpose flour.
- Cocoa powder. Cocoa powder will be replacing some of the flour that would be in a traditional shortbread cookie. Use whatever cocoa powder you like. I've chosen dutch process or alkalized darker cocoa powder. The flavor is similar to Oreos.
First of all: Why Are They Called Shortbread?
Shortbread or a short dough is a dough that gets its name from the interaction that the high ratio of butter has on the gluten proteins in the flour.
The high amount of butter in this dough prevents gluten from forming long bonds, as you might see in bread, and keeps the crumb tight and "short."
The result is a crispy, crumbly dough. This ratio of butter to flour is what makes a shortbread cookie so delicious.
The butter heats up and lightly toasts the flour and sugar during the baking process, giving it a buttery, savory flavor with just a hint of sweetness. The flour is merely holding all of the butterfat molecules in place so that they don't run off the baking sheet.
Good job, butter, and flour! 🏆
Which Cocoa Powder?
Chocolate shortbread involves replacing some of the flour in traditional butter shortbread with cocoa powder. This shortbread cookie recipe calls for dark or black cocoa powder. However, you can substitute any unsweetened cocoa powder.
Cocoa powder has a different chemical composition than flour. You may not realize how much flavor variety there is in cocoa powders.
You're probably familiar with Hershey's Unsweetened Cocoa Powder. Hershey's is a pretty standard and super easy-to-find cocoa powder, and Hershey's cocoa has a well-rounded flavor and is suitable for most baking applications.
Hershey's also has a Special Dark variety of cocoa powder double processed, yielding, and darker flavor. It's more like the flavor that you know from an Oreo cookie.
My favorite Cocoa Powders
I encourage you to try different cocoa powders and find your signature chocolate shortbread cookies.
Using a different cocoa powder than most people are used to tasting gives your cookies that extra special something that leaves everyone wondering what you did to get that unique flavor!
PRO-TIPs for Making Chocolate Shortbread
- Butter and eggs should always be at room temperature before baking.
- Do not whip the butter. You want to blend the butter with the sugar for a long time so that the sugar dissolves into it. However, you don't want to introduce a lot of air into the butter. Excess air will cause the cookies to spread.
- A stand mixer with a paddle attachment makes easy work of shortbread.
- Make sure you have plastic wrap so that you can wrap and chill the dough.
- Chill the dough overnight, if possible.
- Use parchment paper to line your cookie sheets.
Let's Get Baking
- Set all of your ingredients out, make sure the butter and flour are at room temperature.
- Start by sifting together the dry ingredients. I usually add my dry ingredients to a medium bowl and then give them a quick stir with a whisk.
- Add the butter to your stand mixer, fixed with a paddle attachment, and cream the butter until it is creamy and the sugar is dissolved into it.
- Add the sugar. Beat until light in color for about 3 minutes.
- Add the egg and the vanilla. Beat again
- Scrape down the sides and beat one more time.
- Add all of the dry mixture in at once.
- Turn the mixer on low. Beat very slowly until the mixture becomes crumbly.
- Scrape all of the mixture onto the countertop and then press it together.
- Divide the dough into four equal portions and make four eight-inch logs. The logs can be round or rectangular.
- Wrap in plastic and refrigerate for at least four hours and up to overnight.
When You're Ready to Bake
This chocolate shortbread recipe is easy to slice and bake. If you have more cookie dough than you want to bake you can freeze it for several months, or even longer.
- Preheat the oven to 350℉.
- Line baking sheets with parchment paper.
- Slice each log of cookie dough into approximately 12 slices. They will be a little bit fatter than a quarter inch.
- Bake the cookies for 14 to 18 minutes. Watch closely as oven temperatures vary.
Frequently Asked Questions
Touch the edges, and they should feel firm and crispy. The middle of the cookies will still feel slightly soft but should feel like they have a crust on them. They will crisp up as they cool.
Because the cookies are dark, you can't really see if they are browned. I use this "feel" test to figure out if they are done or not.
