Baking doesn't have to mean a sink full of dirty dishes – this cake and cupcake batter can be made in a single bowl! Plus, watch Everyday Food editor Sarah Carey teach you a fun piping technique to make cupcakes extra special.
Preheat oven to 350 degrees. Line standard muffin cups with paper liner. In a large bowl, whisk together sugar, flour, cocoa powder, baking soda, baking powder, and salt. Add buttermilk, vegetable oil, and 1 1/2 cups warm water; whisk to combine. Add eggs and vanilla extract and whisk until smooth.
Divide batter among muffin cups (filling each about 2/3 full) and bake until a toothpick inserted in center of cupcake comes out with a few moist crumbs attached, 20 to 25 minutes. Let cool in pans on wire racks, 5 minutes, then transfer cupcakes to racks and let cool completely. Frost as desired.
