Method: Death by Chocolate Cake

Now, let’s get to the fun part—baking the cake!
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your cakes will bake evenly.
Step 2: Prepare the Cake Pans
Grease and flour your two 9-inch round cake pans. This will help the cakes come out smoothly after baking.
Step 3: Mix Dry Ingredients
In a large mixing bowl, combine the granulated sugar, light brown sugar, all-purpose flour, sifted cocoa powder, baking soda, baking powder, and salt. Whisk them together until well blended.
Step 4: Combine Wet Ingredients
In another bowl, whisk together the large eggs, egg yolks, whole milk, sour cream, vegetable oil, and vanilla extract. Mix until the wet ingredients are well combined.
Step 5: Combine Wet and Dry Mixtures
Gradually add the wet ingredients into the dry mixture, mixing well until there are no lumps. The batter will be quite thick at this point.
Step 6: Add Hot Water
Slowly stir in the hot water until fully incorporated. This will thin out the batter and create a moist cake.
Step 7: Fold in Chocolate Chips
Gently fold in the chocolate chips until evenly distributed throughout the batter.
Step 8: Bake the Cakes
Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
Step 9: Let Them Cool
Once baked, let the cakes cool in the pans for about 10 minutes before transferring them to a cooling rack to cool completely.
Step 10: Prepare the Frosting
In a large bowl, beat the very soft unsalted butter with an electric mixer until creamy. Gradually add the sifted confectioners’ sugar and cocoa powder, mixing until combined. Add the vanilla extract, salt, and heavy cream, beating until the desired consistency is reached.
Step 11: Assemble the Cake
Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of frosting on top, then place the second layer on top. Frost the top and sides of the cake generously.
Step 12: Add Fudge Sauce
Drizzle hot fudge sauce over the top of the frosted cake and sprinkle with chocolate shavings and additional chocolate chips for a stunning finish.
Dairy-Free/Gluten-Free Swaps

If you need to make substitutions, consider the following options:
- Use almond milk or oat milk instead of whole milk.
- Substitute coconut yogurt for sour cream.
- For gluten-free, use a 1:1 gluten-free flour blend in place of all-purpose flour.
- Use dairy-free chocolate chips and cocoa powder.
Troubles You Can Avoid
There are a few common issues that can arise when baking a cake, but with these tips, you can avoid them:
- Make sure all your ingredients are at room temperature before mixing; this helps with a better rise.
- Don’t overmix the batter; mix until just combined to avoid a dense cake.
- Use a toothpick to check for doneness; if it comes out with moist crumbs, it’s perfect.
- Allow the cakes to cool completely before frosting, or the frosting will melt off.
Make Ahead Like a Pro
Planning to serve this decadent cake for a special occasion? Here are some tips to prepare in advance:
You can bake the cakes up to two days ahead. Just wrap them tightly in plastic wrap and store them at room temperature. The frosting can also be made a day in advance; store it in the refrigerator and bring it to room temperature before spreading. Finally, assemble the cake on the day of serving to keep it fresh and beautiful.
Ask & Learn
Can I freeze the cake?
Absolutely! You can freeze the un-frosted cake layers for up to three months. Wrap them tightly in plastic wrap and then in aluminum foil for best results. Thaw them in the refrigerator before frosting.
What’s the best way to serve this cake?
Serve the Death by Chocolate Cake chilled or at room temperature. It pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream for added indulgence.
Can I use different flavors of chocolate?
For a different twist, try using white chocolate in the frosting or dark chocolate for a more intense flavor. You can also experiment with flavored extracts for unique variations.
How can I store leftovers?
Store any leftover cake in an airtight container in the refrigerator for up to five days. If you prefer it at room temperature, just let it sit out for a bit before serving.
