Ingredients

Scale

Cake

  • 1 cup salted butter (2 sticks)
  • 1 cup water
  • 3/4 cup unsweetened cocoa powder
  • 1/4 cup vegetable oil
  • 1 cup brown sugar
  • 1 cup granulated sugar
  • 2 teaspoons vanilla extract
  • 2 cups all purpose flour (spooned and leveled)
  • 3/4 teaspoon kosher salt
  • 1 teaspoon baking soda
  • 3/4 cup sour cream
  • 2 large eggs

Frosting

  • 3/4 cup salted butter (1 and 1/2 sticks)
  • 1/2 cup unsweetened cocoa powder (mounded)
  • 2 cups powdered sugar
  • 1/2 cup sour cream (mounded)
  • 2 teaspoons vanilla extract
  • 1 and 1/2 cups powdered sugar (remaining)
  • 1/4 teaspoon kosher salt

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C). Line a jelly roll pan with parchment paper or spray it generously with nonstick spray.
  2. Make the chocolate base: In a medium or large saucepan, combine 1 cup salted butter, 1 cup water, and 3/4 cup cocoa powder. Bring to a boil over medium-high heat, stirring frequently to avoid burning. Once boiling, remove from heat.
  3. Add sugars and vanilla: Let the mixture cool slightly for 1-2 minutes, then whisk in 1/4 cup vegetable oil, 1 cup brown sugar, 1 cup granulated sugar, and 2 teaspoons vanilla extract until well combined.
  4. Mix dry ingredients: In a separate bowl, spoon and level 2 cups all-purpose flour, then stir in 3/4 teaspoon kosher salt and 1 teaspoon baking soda, blending them together lightly with a spoon.
  5. Combine dry with wet: Whisk the dry ingredients into the chocolate mixture until just combined. Avoid overmixing; a few lumps are okay to keep the cake tender.
  6. Add eggs and sour cream: In a glass measuring cup, beat together 3/4 cup sour cream and 2 large eggs. Fold this mixture into the batter using a spatula, mixing only until combined.
  7. Prepare and bake the cake: Pour the batter evenly into the prepared pan, spreading it to the edges. Bake at 350°F for 17-20 minutes or until a toothpick inserted in the center comes out clean and the edges begin to pull away from the pan.
  8. Make the frosting: Clean the saucepan. Over medium heat, melt 3/4 cup butter with 1/2 cup unsweetened cocoa powder, stirring constantly until it comes to a boil. Remove from heat and whisk in 2 cups powdered sugar until smooth.
  9. Add sour cream and vanilla: Stir in 1/2 cup sour cream and 2 teaspoons vanilla extract. Then whisk in the remaining 1 and 1/2 cups powdered sugar and 1/4 teaspoon kosher salt. Beat vigorously with a whisk or hand mixer until smooth and lump-free.
  10. Frost the cake: Once the cake is out of the oven, allow it to cool 15-20 minutes. Spread the warm frosting evenly over the cake quickly before it sets. Let set for at least 20 to 60 minutes before serving.
  11. Serve suggestion: This cake is fantastic served with a cold glass of milk. For an indulgent treat, stack two slices with frosting between and heat briefly in the microwave for a gooey delight.

Notes

  • Make sure not to overmix the cake batter to maintain a tender crumb.
  • Use parchment paper or proper nonstick spray to ensure easy removal and clean-up.
  • The frosting sets quickly — be ready to spread it as soon as the cake cools a bit.
  • For the best sour cream measurement, gently mound it into the measuring cup rather than packing it down.
  • If frosting develops a hardened shell, stir it occasionally to keep it smooth before spreading.
  • Microwaving two frosted slices stacked makes a warm, fudgy dessert that’s a fan favorite.
  • Use kosher or sea salt interchangeably for best taste.
