These stunning bakery-style cupcakes feature a rich swirl of silky dulce de leche or vanilla buttercream atop moist chocolate and vanilla cupcakes—each one crowned with a cinnamon sugar mini donut for a playful, indulgent finish.
Preheat oven to 350°F (175°C). Line a cupcake pan with liners.
Prepare the chocolate cupcake batter by combining dry ingredients in one bowl and wet ingredients in another. Mix until smooth and stir in hot water last. Set aside.
In another bowl, make vanilla cupcake batter by creaming butter and sugar, then adding eggs, milk, vanilla, and dry ingredients. Mix until smooth.
Fill cupcake liners 2/3 full with the appropriate batters. Bake for 18–20 minutes or until a toothpick comes out clean. Let cool completely.
For dulce de leche frosting: Beat butter until creamy, then add powdered sugar gradually. Mix in dulce de leche and cream until desired consistency is reached.
For vanilla buttercream: Beat butter until creamy, then gradually add powdered sugar, vanilla, and milk until fluffy.
Pipe dulce de leche frosting onto cooled chocolate cupcakes and vanilla buttercream onto vanilla cupcakes.
Top each frosted cupcake with a mini cinnamon sugar donut. Optionally sprinkle with additional cinnamon sugar.
Notes
Use room temperature ingredients for a smoother batter and frosting.
Chill cupcakes slightly before piping for clean frosting swirls.
Mini donuts can be homemade or store-bought for convenience.
Store in an airtight container at room temperature for up to 2 days or refrigerate for longer shelf life.
