Stepwise Method: Chocolate Bundt Cake with Chocolate Fudge Icing

Step 1: Prepare the Bundt Pan
Start by preheating your oven to 350°F (175°C). Grease your Bundt pan with melted butter and dust it with cocoa powder, ensuring every crevice is covered to allow for easy cake release.
Step 2: Melt the Chocolate
In a heatproof bowl, combine the chopped bittersweet chocolate and optional espresso powder. Pour the boiling water over it and let sit for a minute. Stir until smooth and let it cool slightly.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. Set aside.
Step 4: Cream Butter and Sugar
In a large mixing bowl, beat the room temperature unsalted butter and light brown sugar with an electric mixer until light and fluffy, about 3-4 minutes.
Step 5: Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract.
Step 6: Combine Wet and Dry Ingredients
Mix in the sour cream and the melted chocolate mixture until well combined. Gradually add the dry ingredients, mixing just until incorporated.
Step 7: Bake the Cake
Pour the batter into the prepared Bundt pan, smoothing the top. Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. Let it cool in the pan for 10 minutes, then invert onto a cooling rack to cool completely.
Step 8: Prepare the Chocolate Fudge Icing
In a small saucepan over low heat, melt the unsalted butter. Stir in the cocoa powder and evaporated milk until smooth. Gradually mix in the powdered sugar, vanilla extract, and salt until the icing is glossy and pourable.
Step 9: Ice the Cake
Once the cake is completely cool, drizzle the chocolate fudge icing over the top, allowing it to cascade down the sides of the Bundt cake.
Step 10: Serve and Enjoy
Slice the cake and serve it on its own or with a dollop of whipped cream or a scoop of vanilla ice cream for an extra indulgent treat.
If You’re Out Of…

- Bittersweet chocolate – Use semisweet chocolate or a combination of semisweet chocolate and unsweetened cocoa powder.
- Sour cream – Substitute with plain Greek yogurt for a similar texture and tang.
- Evaporated milk – Use whole milk or heavy cream as a substitute in the icing.
- Light brown sugar – Dark brown sugar will work just as well and add a deeper flavor.
