📝 Preparation Steps
1
Cake:
2
Preheat oven to 350°F. Grease three 9-inch cake pans, and line the bottoms with rounds of parchment paper. Set aside.
3
Cake batter
4
In a large bowl, stir together the sugar, flour, cocoa powder, baking powder, baking soda, and salt. Add eggs, milk, oil, and vanilla extract, and beat on medium speed for two minutes with a hand mixer or stand mixer. Add the boiling water and stir to combine, scraping the sides and bottom of the bowl as necessary (the batter will be thin). Divide the batter evenly among the three prepared pans. Use a measuring cup or large glass measuring bowl to help divide the batter evenly.

Bake for ⏱️ 22-25 minutes, until a toothpick inserted into the center of the cakes comes out clean. Place the pans on wire racks to cool completely. You can also refrigerate the cakes (tightly covered) until you're ready to frost them.

With a hand mixer or stand mixer, beat the butter and powdered sugar until creamy and combined, about one minute. Add vanilla extract and milk, and beat for another minute. Add the marshmallow creme and beat until completely combined, about one additional minute.

Assembly
10
Place one layer of cake on a serving platter and spread with half of the marshmallow frosting, leaving a 1/4 to 1/2 inch border around the outside (so the frosting won't spill out the sides). Place another layer of cake on top, and spread with the remaining marshmallow frosting, leaving a 1/4 to 1/2 inch border around the outside. Place the third layer of cake on top of that, and transfer the cake to the refrigerator while you prepare the chocolate frosting.

Whisk or sift powdered sugar and cocoa powder until all lumps are removed. With a hand mixer or stand mixer, beat butter, cocoa powder, and powdered sugar on low speed, then slowly pour in the 1/4 cup milk. Once the ingredients are incorporated, increase the mixer to medium speed and beat for about one minute, until thick and creamy. Add more milk, if needed, to thin out the frosting.

Remove the cake from the refrigerator and frost the top and sides with the chocolate frosting. Immediately pile the mini marshmallows in the center of the cake, lightly pressing them down to help them stick to the frosting.

Garnish
17
Heat the chocolate chips and 1 teaspoon milk in the microwave in ⏱️ 15-20 second increments, until smooth and creamy, stirring frequently. Drizzle the marshmallows with melted chocolate (this will help them stick together). Place the cake in the refrigerator to allow the frosting to firm up. Allow the cake to sit at room temperature for an hour before serving.
