For the Chocolate Frosting

  • 0.5 cup unsweetened cocoa powder
  • 4 cups powdered sugar
  • 0.5 cup heavy cream
  • 1 tsp vanilla extract

  • Electric Mixer
  • Medium bowl
  • Small Bowl
  • Whisk
  • Toothpick
  • Wire rack

Method
 

  1. Step 1: Preheat Oven & Prepare Pan: First things first, get your oven to 325°F (163°C). Then, you'll want to generously grease and flour your Bundt pan or 10-inch tube pan. Don't skip this step, friend; it’s crucial for a clean release!
  2. Step 2: Prepare Batter: In a large bowl, cream together your softened butter, vegetable oil, and granulated sugar until the mixture is beautifully light and fluffy (about 4-5 minutes with an electric mixer). Next, add the large eggs, one at a time, mixing thoroughly after each addition. Stir in your vanilla extract.
    In a separate medium bowl, whisk together your flour, cocoa powder, baking powder, and salt. In another small bowl, combine your whole milk and sour cream. Gradually add the dry ingredients to your butter mixture, alternating with the milk mixture, starting and ending with the dry ingredients. Mix until everything is just smooth; do not overmix.
  3. Step 3: Bake Cake: Pour your batter into the prepared pan and gently smooth the top. Bake for 70-80 minutes, or until a toothpick inserted right into the center comes out perfectly clean. Let the cake cool in the pan for about 15 minutes. After 15 minutes, carefully flip it onto a wire rack to cool completely.
  4. Step 4: Prepare Frosting: While your cake is cooling, in a medium bowl, beat your softened butter until wonderfully creamy. Then, add the cocoa powder and mix until perfectly smooth. Gradually add the powdered sugar, alternating with the heavy cream, beating until the frosting is thick, smooth, and easily spreadable. Finish by stirring in the vanilla extract and a pinch of salt.
  5. Step 5: Assemble: Once your chocolate pound cake is completely cool to the touch, spread or pipe the luscious chocolate frosting evenly over the top and sides.

Notes

Substitutions & Additions: Try different extracts like almond, peppermint, or coffee. For dairy-free, swap whole milk for plant-based milk and sour cream for a dairy-free alternative or plain plant-based yogurt. Fold in a cup of chocolate chips for extra chocolatey goodness. Add 1-2 teaspoons of instant espresso powder to deepen the chocolate flavor. A little orange zest (1-2 teaspoons) can brighten the chocolate flavor. Garnish with shaved chocolate, chocolate curls, a sprinkle of sea salt, or fresh raspberries, and serve with vanilla bean ice cream.
Tips for Success: Room temperature ingredients (softened butter, eggs, milk, sour cream) are crucial for a smooth batter and tender crumb. Do not overmix the batter to avoid a tough cake. Measure flour correctly by spooning it into the measuring cup and leveling it off. Thoroughly grease and flour your pan, especially for Bundt pans. Cool the cake completely before frosting to prevent melting.
How to Store: Store frosted cake in an airtight container at room temperature for up to 3-4 days, or in the refrigerator for up to a week (bring to room temperature before serving). Unfrosted cake can be tightly wrapped and frozen for 2-3 months. Leftover frosted slices can be flash-frozen, then wrapped and frozen for up to a month.
