These chocolate and vanilla Marble Cupcakes are cute and fun yet so easy to make. The cupcakes themselves are tender, moist, and so pretty and delicious that you could serve them without the swirled frosting. Call them muffins, if you want, which makes them an acceptable breakfast, right?

The Marble Cream Cheese Frosting is really the best part of these cupcakes. The flavor is sensational and I love the marbled look of the frosting.
I used my Cream Cheese Frosting recipe for these and added some melted chocolate to half of it to make the chocolate cream cheese frosting. The chocolate cream cheese frosting turned out amazing! It has an intense chocolate flavor while accentuating the cream cheese and vanilla flavors. I think I will put it on everything I bake from now on. 😉
To marble the frosting, lay a pastry bag fitted with a large star tip on your work surface and fill the bottom half with the vanilla frosting. Then fill the top half with the chocolate frosting. Pipe swirls of frosting onto the cupcakes, starting at the outside edge of the cupcake and ending in the middle.
Marble Cupcakes with Marble Cream Cheese Frosting
- ½ cup (113 g) butter melted
- ¾ cup (150 g) granulated sugar
- 1 egg
- 1 cup (240 ml) buttermilk
- 2 teaspoons vanilla extract
- 1 ⅔ cups (230 g) all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon baking soda
- ½ teaspoon salt
- ¼ cup (20 g) cocoa powder + 1 tablespoon brewed coffee
Marble Cream Cheese Frosting
- ½ cup plus 1 tablespoon (125 g) butter room temperature
- 2 ¾ cups (300 g) powdered sugar
- 1 teaspoon vanilla extract
- 5 ¼ ounces (150 g) cream cheese spread full fat, room temperature
- 1 ¾ ounces (50 g) bittersweet chocolate melted
- For the cupcakes: Preheat oven to 350°F (175°C). Line muffin tins with 14 cupcake liners.
- Whisk melted butter and granulated sugar together in a large mixing bowl. Add egg, buttermilk and vanilla extract and whisk together. In a separate, medium-sized bowl, whisk together flour, baking powder, baking soda and salt. Add the dry ingredients to the wet mixture and stir just until combined. Transfer half of the batter to another bowl and add cocoa powder and 1 tablespoon brewed coffee (or buttermilk). Stir until combined.
- Spoon 1 teaspoon of the vanilla batter into each cupcake liner, followed by 1 teaspoon of the chocolate batter, alternating until the batters are used up. Gently swirl the batters together with a knife to create the marble effect. Bake for 16-18 minutes until a toothpick comes out clean. Remove from oven and cool in the pans on a wire rack for 5 minutes. Transfer cupcakes to a wire rack to cool completely.
- For the frosting: Beat the butter in the bowl of a stand mixer on high speed until light and fluffy. Add the powdered sugar, one third at a time, and beat on high speed for several minutes until mixture is light and creamy. Beat in vanilla. Add the cream cheese and beat on high for a couple of seconds to incorporate. Scrape the bowl and beat on high again for a couple of seconds. Transfer half of the frosting (about 300 g) to another bowl. Beat the cooled melted chocolate into the remaining frosting to make the chocolate frosting.
- To frost the cupcakes: For marbled frosting, use a large star tip and fill one side of the piping bag with vanilla cream cheese frosting and fill the other half with the chocolate cream cheese frosting so the two frostings are side by side in the piping bag (see photo). Pipe swirls of frosting onto the cooled cupcakes.
- Store frosted cupcakes tightly covered in the refrigerator for up to four days. The cupcakes taste best if you take them out of the refrigerator 15-30 minutes before serving. Unfrosted cupcakes may be stored at room temperature.
