Chocolate Cupcakes with Marshmallow Cream Filling -- The Cake That Made the Whole Building Smell Like a Chocolate Factory

Election week (local). I voted, as always, because Babcia's ghost would haunt me if I didn't. More importantly: I pitched the big idea to Milwaukee Eats. A four-part series: "From the Old Country to the New Kitchen: Polish Food in Milwaukee." Part one: the immigrants (1880s-1940s). Part two: the establishment (1940s-1990s). Part three: the grandmothers (the preservers, the carriers, the Babcias). Part four: the future (guys like me, trying to keep it alive). Each part would be four to five thousand words, with recipes, photos, and interviews with families across the city. Claire, the editor I've been working with, called me back the same day. "This is exactly what we want to publish," she said. "But it's going to take months. Can you handle that alongside the monthly column?" I said yes. I can handle it because I have to handle it. This story needs to be told, and I seem to be the person standing in front of it. I'm going to start the research this month. Polish Center archives. Milwaukee Historical Society. Interviews with Mrs. Wojcik and the women in her pierogi class. Visits to the old Polish churches — St. Josaphat, St. Stanislaus, Basilica of St. Hyacinth. I want to understand the full arc, not just my piece of it. Dad's birthday dinner is next week. He's turning fifty-two. Last year I did the beer-braised short ribs and he said, "You're a hell of a cook, kid." This year I want to push further. I've been planning: a whiskey-brined pork chop (thick-cut, bone-in, brined in bourbon and brown sugar and sage), Babcia's potato pancakes (because they're his favorite and you don't mess with a man's favorite), roasted Brussels sprouts with bacon (because even Dad likes vegetables when there's bacon), and for dessert, a chocolate stout cake made with Forest Floor. The chocolate stout cake is new. Three layers. Dark, rich, with the roast and bitter chocolate from the beer deepening the flavor. Cream cheese frosting. I tested it this weekend and it was so good that Mike and Amy came upstairs and asked what I was baking because their apartment smelled like "a chocolate factory." I gave them a slice. Amy said, "This is the best cake I've ever had." Mike said, "Dude, open a bakery." Everyone has an opinion about what I should open.

The chocolate stout cake I tested this weekend was the proof-of-concept for Dad’s birthday table — dark, bitter, layered with cream cheese frosting — but the soul of it is the same soul in these chocolate cupcakes: deep cocoa, a rich crumb, and a creamy surprise at the center that makes the whole thing feel like it was worth the effort. If you want that “chocolate factory” smell drifting through your building and neighbors showing up at your door, this is your starting point. Make these when you need a dessert that says you meant it.

Chocolate Cupcakes with Marshmallow Cream Filling

Prep Time: 20 min | Cook Time: 20 min | Total Time: 40 min | Servings: 24 cupcakes

Ingredients

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 3/4 cup unsweetened cocoa powder
• 2 teaspoons baking soda
• 1 teaspoon baking powder
• 1 teaspoon salt
• 2 large eggs
• 1 cup buttermilk
• 1 cup strong brewed coffee, cooled
• 1/2 cup vegetable oil
• 1 teaspoon pure vanilla extract
• Marshmallow Cream Filling:
• 4 oz cream cheese, softened
• 1 cup marshmallow creme (such as Jet-Puffed)
• 1/2 cup powdered sugar
• 1 teaspoon vanilla extract
• Chocolate Frosting:
• 1/2 cup unsalted butter, softened
• 2/3 cup unsweetened cocoa powder
• 3 cups powdered sugar
• 1/3 cup milk
• 1 teaspoon vanilla extract

Instructions

1. Preheat and prep. Preheat oven to 350°F. Line two standard 12-cup muffin tins with paper liners and set aside.
2. Mix the dry ingredients. In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until evenly combined.
3. Mix the wet ingredients. In a separate bowl, whisk eggs, buttermilk, cooled coffee, vegetable oil, and vanilla extract until smooth.
4. Combine. Pour the wet ingredients into the dry ingredients and stir until just combined — do not overmix. The batter will be thin; that’s correct.
5. Fill and bake. Fill each cupcake liner about 2/3 full. Bake 18–20 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs. Cool completely on a wire rack before filling or frosting.
6. Make the filling. Beat cream cheese until smooth. Add marshmallow creme, powdered sugar, and vanilla; beat on medium until fluffy and well combined, about 2 minutes.
7. Fill the cupcakes. Using a small paring knife or a cupcake corer, cut a small well in the center of each cooled cupcake about 1 inch deep. Spoon or pipe approximately 1 tablespoon of marshmallow cream filling into each well.
8. Make the frosting. Beat butter and cocoa together until blended. Gradually add powdered sugar, alternating with milk, beating on medium-high until smooth and spreadable. Mix in vanilla. Add a splash more milk if needed to reach piping consistency.
9. Frost and serve. Pipe or spread chocolate frosting over each filled cupcake. Serve at room temperature. Store covered at room temperature up to 2 days or refrigerate up to 5 days.
