🛒 Ingredients

  • For the Cake:

    • 2 cups all-purpose flour 🌾

    • 2 cups granulated sugar 🍯

    • ¾ cup unsweetened cocoa powder 🍫

    • 2 tsp baking soda and 1 tsp baking powder

    • 1 tsp salt 🧂

    • 1 cup buttermilk (at room temperature) 🥛

    • ½ cup vegetable oil 🌻

    • 2 large eggs 🥚

    • 2 tsp vanilla extract

    • 1 cup hot coffee or boiling water (this “blooms” the cocoa for deeper flavor) ☕

  • For the Topping:

    • 1 cup semi-sweet chocolate chips 🍫

    • ½ cup heavy cream 🥛

    • Chocolate sprinkles 🎊


🔪 Step-by-Step Instructions

  1. Prep Work ➡️ Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.

  2. Mix Dry Ingredients ➡️ In a large bowl, whisk together the flour, sugar, cocoa, baking soda, baking powder, and salt. 🥣

  3. Add Wet Ingredients ➡️ Add the eggs, buttermilk, oil, and vanilla extract. ➡️ Beat on medium speed for about 2 minutes until well combined.

  4. The Secret Step ➡️ Lower the speed and carefully pour in the hot coffee or boiling water. ➡️ The batter will be very thin—this is normal and ensures a moist crumb!

  5. Bake ➡️ Pour the batter into the prepared pan. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. ➡️ Let the cake cool completely in the pan.

  6. Prepare the Ganache ➡️ Heat the heavy cream until it just begins to simmer. Pour it over the chocolate chips in a small bowl. ➡️ Let it sit for 5 minutes, then stir until shiny and smooth.

  7. Glaze and Garnish ➡️ Pour the warm ganache over the cooled cake, spreading it to the edges. ➡️ Immediately top with a generous layer of chocolate sprinkles while the glaze is still wet.

  8. Set and Slice ➡️ Let the glaze set for at least 30 minutes before slicing into squares. 🍽️


❓ Q/A Section

Q: Can I taste the coffee in the cake? A: Not at all! ➡️ The coffee simply intensifies the chocolate flavor. If you prefer to avoid it, boiling water works perfectly fine.

Q: Why is my batter so watery? A: Don’t worry! ➡️ This high-moisture batter is exactly what makes the cake so soft and prevents it from becoming dry.

Q: Can I make this in a different pan? A: Yes! ➡️ This recipe works for two 9-inch round pans (bake for 30-35 mins) or about 24 cupcakes (bake for 18-22 mins).

Q: How should I store the leftovers? A: Cover the pan tightly with foil or plastic wrap. ➡️ It stays moist at room temperature for up to 3 days or in the fridge for up to 5 days.
