Frosted Chocolate Sugar Cookies
Fudgy dark chocolate sugar cookies are frosted with a creamy chocolate buttercream frosting. Inspired by Swig’s Dirtball Cookie, these frosted chocolate sugar cookies are sure to be a new favorite!
This month I am celebrating my blog’s 5th birthday/ anniversary/ blogiversary … whatever you want to call it. To celebrate, I felt like recreating one of my favorite desserts – Swig’s Dirtball Cookie, which is basically a frosted chocolate sugar cookie.
If you are from Utah like me, you probably know about the soda shop craze that we have here. They are popping up EVERYWHERE. There are a variety of different ones. The best one in my town is Swig. I was a FIIZ fan until I moved and now the closest FIIZ to me is 30 minutes away. Thank goodness Swig moved into town!

Anyway, I used to love getting the sugar cookie at FIIZ. The one at Swig seemed dry to me, but my friend Nikki took me to Swig one day and told me to get the Dirtball Cookie and it has forever changed my life! Delicious!
Dirtball cookies are HUGE, thick, fudgy, dense, almost brownie-like cookies topped with chocolate frosting. So of course, I had to research some recipes, and alter them to come up with a recipe of my own. These are obviously smaller, which means you can eat more than one, but this way you can share too.
The most important thing is to not press the chocolate sugar cookies too thin before baking. About 1/2-inch thick is thin enough. Then do your absolute best not to over-bake them. These chocolate sugar cookies literally take 6 minutes to bake. For real! Think about how fast you’ll be popping these bad boys out of your oven! Fast enough to make a second batch. 😉
The chocolate frosting on top of these chocolate sugar cookies is made with half butter and half coconut oil. It’s my favorite way to make “buttercream,” although if you don’t have coconut oil, all butter is fine. Coconut oil is a healthy fat and helps add stability to the frosting.
Anyway, this recipe has lots of cocoa and extra milk to make it decadent and creamy! I won’t even tell you how many I ate when I first made them — okay, five! I’m not even sorry about it. I hope you get the chance to try these frosted chocolate sugar cookies! They would make great cookies for a Christmas cookie exchange party. Happy 5th Blogiversary to me!
Frosted Chocolate Sugar Cookies
Ingredients
Cookies:
- 1 cup (226 g) unsalted butter, (2 sticks) room temperature
- 1 cup (200 g) brown sugar, gently packed
- ½ cup (100 g) granulated sugar
- 2 tsp pure vanilla extract
- 2 large eggs
- 2 cups (240 g) all-purpose flour, (stir, spoon & level)
- 1 tsp baking soda
- 2 tsp cornstarch
- 1 cup (80 g) cocoa powder, (I used dark cocoa powder)
- ¼ cup (50 g) extra granulated sugar, for flattening the cookies
Frosting:
- 4 Tbsp (57 g) unsalted butter, room temperature
- 4 Tbsp (57 g) coconut oil, room temperature (can use all butter, if desired)
- 3 cups (360 g) powdered sugar, sifted
- ⅔ cup (54 g) cocoa powder, (I used dark cocoa powder) sifted
- ¼ tsp salt
- 2 tsp vanilla
- ⅓ cup (80 ml) milk, (+ additional teaspoons until desired consistency)
Instructions
- Line baking trays with parchment paper or silicone baking mats. Preheat oven to 350 degrees Fahrenheit.
- In the bowl of a stand mixer with the paddle attachment, cream the butter and sugars. Add the vanilla and eggs. Beat until smooth.
- Sift in the flour, baking soda, cornstarch, and cocoa powder. Stir until combined.
- Scoop the cookie dough and round into balls (about 1½ Tbsp each). Place on prepared baking sheets, 2-inches apart. Flatten to ½-inch thick with the bottom of a drinking glass dipped in sugar to prevent sticking.
- Bake at 350˚F for 6 minutes. Remove from oven and rest on baking sheet for a couple minutes before transferring to a wire rack to cool completely.
- With an electric hand mixer and a large bowl, beat the butter and coconut oil together until smooth. Add the sifted powdered sugar, cocoa powder, and salt. Then add the vanilla and milk. Mix thoroughly. Add extra milk 1 teaspoon at a time to desired consistency.
- Spread frosting over cooled cookies and enjoy! Store cookies in a sealed container at room temperature up to 5 days.
