How to Make Death by Chocolate Cake
Make Chocolate Simple Syrup: In a small saucepan, heat 1 cup of water with 1 cup of granulated sugar over medium heat, whisking until dissolved. Stir in ½ cup of cocoa powder, remove from heat, and let cool. Set aside for later.
Prepare Cake Layers: Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper for easy removal once baked.
Mix Batter: In a large mixing bowl, whisk together 2 cups of all-purpose flour, 2 cups of granulated sugar, ¾ cup of dark cocoa powder, 1 and ½ teaspoons of baking powder, 1 and ½ teaspoons of baking soda, and 1 teaspoon of fine salt.
Combine Wet Ingredients: In another bowl, whisk together 1 cup of vegetable oil, 4 large eggs (room temperature), 1 cup of full-fat sour cream, 1 cup of water, and 2 teaspoons of vanilla extract until smooth.
Merge Mixtures: Pour the wet ingredients into the dry mixture, stirring gently until just combined. Be careful not to over-mix; a few lumps are okay.
Bake Cake Layers: Divide the batter evenly between the prepared pans. Bake for 22-26 minutes, or until a toothpick inserted in the center comes out with moist crumbs.
Cool Layers: Allow the cakes to cool in the pans for 15 minutes. Then, carefully remove them from the pans and place on wire racks to cool completely.
Level Cake Layers: Once cooled, use a serrated knife to trim the tops of the cakes, ensuring they're level for stacking.
Make Buttercream Frosting: In a mixing bowl, beat 1 cup of room temperature unsalted butter until creamy. Gradually add ½ cup of dark cocoa powder, 4 cups of powdered sugar, and ½ cup of heavy whipping cream, beating until fluffy and smooth.
Assemble Cake: Place one cake layer on a serving plate. Brush generously with chocolate simple syrup, then spread a layer of buttercream on top. Stack the second cake layer and repeat the process.
Frost and Decorate: Finish by spreading the remaining buttercream all over the top and sides of the cake. For an extra touch, press mini chocolate chips onto the outer frosting.
Optional: Serve with a scoop of vanilla ice cream for an indulgent twist!

How to Store and Freeze Death by Chocolate Cake

Freezer: For longer storage, wrap uncut and unfrosted cake layers tightly in plastic wrap and aluminum foil. They can be frozen for up to 1 month.

Expert Tips
• Measurement Matters: Use a kitchen scale for precise ingredient measurements, ensuring consistent results in your Death by Chocolate Cake.
• Room Temperature Ingredients: Allow eggs and sour cream to reach room temperature before mixing, helping them blend smoothly into the batter.
• Don't Overmix: Mix the batter just until combined. Overmixing can lead to a dense cake instead of the desired light texture.
• Cool Layers Completely: Ensure cake layers are fully cooled before frosting to prevent melting the butter in your buttercream.
• Level for Success: Trim the tops of the cake layers for even stacking. This keeps your cake from leaning and looking unbalanced.
• Prep Ahead: Prepare the chocolate simple syrup and cake layers in advance. It saves time and enhances flavor, making your cake even more indulgent!

Death by Chocolate Cake Recipe FAQs
What kind of cocoa powder should I use for the best flavor?
For the richest flavor in your Death by Chocolate Cake, I recommend using high-quality dark cocoa powder. Dutch-processed cocoa gives a mellow chocolate taste, while unsweetened cocoa retains a more intense flavor. Both will work, but the quality of cocoa transforms the taste.
How should I store my leftover cake?
To keep leftovers fresh, cover your cake with plastic wrap or foil and store it in the refrigerator for up to 1 week. If you prefer keeping it at room temperature, an airtight container will maintain its moist texture for 1-2 days. This way, you can savor the rich chocolatey goodness without losing quality!
Can I freeze the cake layers?
Absolutely! To freeze your uncut and unfrosted cake layers, allow them to cool completely. Then wrap each layer tightly in plastic wrap and aluminum foil. They can be stored in the freezer for up to 1 month. When you’re ready to enjoy, just thaw them in the fridge overnight, frost, and serve!
What if my cake layers are uneven after baking?
No worries! If your cake layers have domed tops, simply level them with a serrated knife once cooled. This ensures each layer stacks evenly, making for a beautifully balanced cake. A little trimming goes a long way in achieving that professional look!
Can I make this recipe gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free blend that includes xanthan gum. Make sure to check for certified gluten-free labels on your flour to avoid any cross-contamination. Your Death by Chocolate Cake will still be decadently delicious!
What dietary considerations should I keep in mind?
If you’re catering to dietary restrictions, consider using non-dairy alternatives, such as almond milk instead of sour cream, and dairy-free butter for the frosting. You can also find dark chocolates that are dairy-free or vegan to maintain that sumptuous chocolate flavor while accommodating dietary needs.
