These homemade Fudgee-O cookies are extra soft, intensely chocolatey, and seriously addictive. This simple recipe uses a chocolate cake mix for the cookies, finished with a creamy chocolate frosting for the perfect sandwich cookie.
I love chocolate cookies, and these homemade Fudgee-O sandwiches may become a new favorite. They’re soft, chewy with a slightly cakey texture, and paired with a rich chocolate frosting they’re impossible to resist.
Recently I’ve experimented with several cake mix cookie recipes—it’s an easy, reliable way to get great texture and flavor. This version ramps up the chocolate with a Devil’s food cake mix for a deep cocoa taste and a creamy frosting to sandwich the cookies together.
How to Make Homemade Fudgee-O Cookies
These chocolate sandwich cookies are quick and straightforward. The full recipe is below, but here are the basic steps so you know what to expect.
- Beat together the oil and eggs until combined.
- Add one box of chocolate cake mix (Devil’s food recommended) and mix to form a dough.
- Portion the dough into balls—use a cookie scoop for uniform cookies—and place them on a lined baking sheet.
- Flatten each ball slightly and press a small indent in the center so cookies don’t puff too much while baking.
- Bake 7–8 minutes, until the tops are set but still soft.
I prefer Devil’s food cake mix for its richer chocolate flavor, but other chocolate mixes will also work.
The frosting is just as simple and very creamy:
- Melt butter and cocoa powder together in a small saucepan, stirring until smooth.
- Let the chocolate mixture cool slightly before proceeding.
- Beat in powdered sugar, then add milk a tablespoon at a time until you reach your desired consistency.
Once the cookies are baked and the frosting is ready, spread frosting on the bottom of one cookie and sandwich another on top. From start to finish these take about 45 minutes and yield a dozen irresistible chocolate sandwich cookies.
These cookies stay soft and chewy rather than dry or crisp, with a slightly cake-like crumb. If you prefer cookies that are cakey and tender with a touch of gooeyness, these homemade Fudgee-O sandwiches are ideal.
Below is the full ingredient list and step-by-step instructions for baking and assembling these cookies.
Homemade Fudgee-O Cookies
Ingredients
Chocolate Cookies
- 6 tablespoons vegetable oil (canola works too)
- 2 large eggs
- 1 18 oz box Devil’s food cake mix
Chocolate Frosting
- 6 tablespoons unsalted butter
- 1/3 cup cocoa powder
- 1 1/2 cups powdered sugar
- 2-3 tablespoons milk (add to reach desired consistency)
Instructions
Chocolate Cookies
- Preheat the oven to 350°F (175°C) and line cookie sheets with parchment paper or silicone baking mats.
- In a large bowl, beat together the vegetable oil, eggs, and cake mix until combined and a dough forms.
- Form dough into balls about 1 to 1.5 tablespoons in size and place them about 2 inches apart on the prepared sheets.
- Flatten each ball slightly and press a small indent into the center to prevent excess puffing during baking.
- Bake for 7–8 minutes, or until the tops are set. Let the cookies cool on the pan briefly, then transfer to a wire rack to cool completely before assembling.
Chocolate Frosting
- In a small saucepan, melt the butter and cocoa powder together over low heat, stirring until smooth and lump-free.
- Pour the mixture into a bowl and allow it to cool slightly so it doesn’t melt the powdered sugar.
- Beat in the powdered sugar, then add milk one tablespoon at a time until you reach a spreadable frosting consistency.
- Spread frosting on the bottom of one cookie and sandwich a second cookie on top. Repeat until all cookies are assembled.
Notes
*Store cookies in an airtight container at room temperature for best texture.
