Slice-and-Bake Chocolate Shortbread Cookies
These slice-and-bake chocolate shortbread cookies are buttery, crisp, and deeply chocolatey. The dough comes together in one bowl, chills into a log, and slices into neat rounds.
No rolling, no cutters, just rich chocolate cookies whenever you want them. They are the kind of cookie you can pull from the freezer and have warm out of the oven in under 20 minutes.
Why These Shortbread Cookies Stay in the Rotation
The cocoa and butter meld into a deep chocolate flavor that is not too sweet, and the texture is sandy and crisp at the edges with a tender center. They are sturdy enough to dip in coffee but delicate enough to feel like a real treat.
The real reason I keep making them is the log in my freezer. A fresh-baked cookie is never more than 15 minutes away, and that beats any store-bought version.
Ingredients
- 1 cup unsalted butter, softened: use a good butter you like the taste of, it carries the cookie
- 1/2 cup powdered sugar: dissolves completely for a melt-in-your-mouth crumb
- 1 teaspoon vanilla extract: rounds out the chocolate
- 1/4 teaspoon salt: fine sea salt, it sharpens the chocolate flavor
- 1/3 cup unsweetened cocoa powder: Dutch-process gives a deeper color and smoother flavor
- 1 1/3 cups all-purpose flour: spoon and level to avoid dense cookies
Variations / Substitutions
- Dark cocoa powder: swap in black cocoa for an Oreo-like intensity, the cookies will be darker and slightly more bitter
- Espresso powder: add 1 teaspoon espresso powder with the cocoa to boost the chocolate notes without tasting like coffee
- Almond extract: replace the vanilla with 1/2 teaspoon almond extract for a nutty chocolate cookie
- Gluten-free: use a 1-to-1 gluten-free flour blend, the texture will be a touch more crumbly
- Chocolate dip: once cooled, dip half of each cookie in melted dark chocolate and let set on parchment

How to Make Slice-and-Bake Chocolate Shortbread Cookies
Step 1: Cream the Butter and Sugar
In a large bowl, beat 1 cup softened butter with an electric mixer on medium speed until smooth, about 1 minute. Add 1/2 cup powdered sugar and beat until light and fluffy, about 2 minutes, scraping down the bowl as needed. Beat in 1 teaspoon vanilla extract and 1/4 teaspoon salt.
The mixture should look pale and have the texture of thick frosting. This aeration is what gives the cookies their tender crumb.
Step 2: Mix the Dry Ingredients
Sift 1/3 cup cocoa powder and 1 1/3 cups flour together into the butter mixture, then mix on low speed just until the dough comes together in a smooth ball. It will look dry at first but will gather as you mix.
Resist the urge to keep mixing. Stop as soon as no dry streaks remain. The dough will be soft but not sticky, with a deep chocolate color.
Step 3: Shape and Chill the Log
Turn the dough onto a sheet of plastic wrap and shape it into a log about 2 inches in diameter and 8 inches long. Roll it tightly in the plastic, twist the ends to seal, and refrigerate for at least 2 hours, until firm and sliceable.
The longer chill firms the butter so the cookies hold their round shape when sliced. You can speed this by freezing the log for 30 minutes if you are in a hurry.
Step 4: Slice and Bake the Cookies
Preheat the oven to 325°F (160°C) and line a baking sheet with parchment paper. Unwrap the log and slice it into 1/4-inch-thick rounds with a sharp serrated knife, rotating the log as you go to keep the shape even. Place the rounds 1 inch apart on the sheet.
Bake for 12 to 15 minutes, until the edges are set and the tops look dry. The cookies will be soft when hot but will crisp as they cool. Let them rest on the baking sheet for 5 minutes, then transfer to a wire rack. Serve warm or let cool completely; the chocolate flavor deepens as they cool.
Tips for the Best Chocolate Shortbread
- Chill the dough thoroughly: even an extra 15 minutes in the freezer after the initial chill helps the butter set and keeps the edges sharp during slicing.
- Roll the log smooth: after wrapping, roll the log on the counter a few times to smooth out bumps and make it evenly round. This prevents misshapen cookies.
- Watch the bake time: the cookies should be dry on top and just set at the edges, not browned. Overbaking turns them bitter.
- Freeze a spare log: the wrapped dough freezes well for up to 3 months. Slice straight from frozen and add 2 minutes to the bake time.
Keeping Chocolate Shortbread Fresh
Store cookies in an airtight container at room temperature for up to 5 days. They stay crisp if the container is not opened too often while warm. No need to refrigerate.
What to Serve with Chocolate Shortbread Cookies
These cookies are made for dunking. A strong cup of black coffee or a cold glass of milk are the obvious partners, and they work because the bitterness of the coffee or the creaminess of the milk balances the chocolate.
For an after-dinner upgrade, crumble a couple over vanilla ice cream with a drizzle of olive oil and a pinch of flaky salt. The sandy cookie texture holds up beautifully and adds crunch.
Frequently Asked Questions
Can I use regular granulated sugar instead of powdered?
You can, but the texture will be grainier and the cookies will spread more. Powdered sugar dissolves fully and gives that classic shortbread melt.
Can I use margarine instead of butter?
I would not. Butter provides the flavor and the crisp edges that define shortbread. Margarine will give you a softer, less flavorful cookie.
Can I add chocolate chips?
Yes, fold in 1/4 cup mini chocolate chips after mixing the dry ingredients for little bursts of chocolate. The cookies may spread slightly thinner.
Can I make these dairy-free?
You can use a plant-based butter stick that is at least 80% fat. The texture will be similar but the cookie will not be quite as flaky.
