Ingredients
Devil's food cake mix
1 (18 ounce) (Use as directed.)
Eggs
3 (Make sure they are at room temperature.)
Buttermilk
1/2 cup (Measure out.)
Oil
1/4 cup (Can use vegetable or canola oil.)
Water
1/2 cup (Warm slightly if desired.)
Unsalted butter
12 tablespoons (Softened but still cool (1 1/2 sticks).)
Confectioners' sugar
1 1/4 cups (Sift before measuring for best texture.)
Vanilla extract
1 1/2 teaspoons (Use pure for best flavor.)
Table salt
1/8 teaspoon (Standard table salt.)
Marshmallow cream
2 1/2 cups (Use straight from the jar.)
Instructions
1
Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy removal.
2
In a large mixing bowl, combine the devil's food cake mix, eggs, buttermilk, oil, and water. Mix until well-blended and smooth, ensuring there are no lumps.
3
Divide the batter evenly between the two prepared cake pans and smooth the tops with a spatula.
4
Bake in the preheated oven for approximately 20 minutes or until a toothpick inserted in the center comes out clean and the cakes spring back when lightly pressed.
5
Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely, about 1 hour.
6
While the cakes are cooling, prepare the marshmallow filling. In a mixing bowl, use an electric mixer on medium speed to beat the softened butter and confectioners' sugar together until fluffy and light, about 2 minutes.
7
Add the vanilla extract and table salt to the butter mixture and mix until well-combined. Gradually beat in the marshmallow cream until smooth and fully incorporated, about 2 more minutes.
8
Once the cakes are completely cool, spread a generous layer of the marshmallow filling over the top of one cake layer. Carefully place the second cake layer on top to form a sandwich.
9
For added indulgence, warm a can of frosting in the microwave for about 20 seconds and pour it over the top of the assembled cake, allowing it to drip down the sides.
10
Refrigerate the finished cake in an airtight container for up to 3 days to keep it fresh and delicious. Cut into wedges and serve to enjoy!
