Best One-Bowl Chocolate Cake Recipe

The easiest and best One-Bowl Chocolate Cake recipe is super chocolatey, light, fluffy, tender, and moist and hardly any more work than using a box cake mix.  This chocolate cake made from scratch is simply the best!
  • 2 cups all-purpose flour (250g)
  • 2 cups granulated sugar (400g)
  • ¾ cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 cup boiling water

Chocolate Frosting

  • 1 cup salted butter, softened (2 sticks)
  • Pinch of salt
  • ¾ cup cocoa powder
  • 4 cups powdered sugar
  • 2 teaspoons pure vanilla extract
  • ¼ cup heavy cream + more as needed


  • Preheat oven to 350°F. Spray a 9x13-inch baking dish with cooking spray or line two 9-inch cake pans with parchment paper circles and spray sides with cooking spray.
  • Whisk flour, sugar, cocoa powder, baking soda, baking powder, and salt together in a large bowl.  
  • Add the buttermilk, oil, eggs, and vanilla and mix on medium speed using a hand mixer or stand mixer until combined.  
  • Add the hot water and mix on low speed until combined. Scrape bottom and sides of the bowl and mix on medium speed for 30 seconds.
  • Pour into the baking dish or divide evenly between cake pans. Bake for 32-37 minutes for a rectangular cake, or 30-35 minutes for 9-inch round cake pans until a toothpick inserted into the center of the cake comes out clean.  
  • Cool completely before frosting.

Chocolate Frosting

  • In a large bowl, beat the butter, salt and cocoa powder together until creamy and smooth.
  • Gradually add the powdered sugar 1 cup at a time, with 1 tablespoon of the cream at a time, mixing between each addition and scraping down the sides of the bowl as needed. Add additional cream as needed and continue to beat for about 5 minutes until light and fluffy.
