Chocolate cake with boiled icing is a delightful dessert that combines rich chocolate cake with a unique type of icing known as boiled icing.
I am always active a soft spot for classic desserts, and chocolate cake has been a favorite for as long as I can remember.
However, I wanted to try something different, so I decided to pair a rich, moist chocolate cake with a light, marshmallow-like boiled icing.
What made me decide to bake this particular chocolate cake with boiled icing version was the unique texture contrast between the dense, decadent cake and the fluffy, smooth icing that beautifully complements it.
The combination of sour cream in the chocolate cake with boiled icing adds a slight tanginess, which balances out the sweetness of the icing, making this dessert stand out.
I’ve tried many chocolate cakes, but this one, with its distinct icing, feels like an elevated twist on the classic.

In a large mixing bowl, combine the flour, baking soda, sugar, cocoa powder, and salt. Mix thoroughly.

Add the softened butter, egg, sour cream, and vanilla extract to the dry ingredients. Mix using an electric mixer or whisk until smooth and well-combined.

Tips And Tricks
1. Always make sure your ingredients are at room temperature, especially butter and eggs. It makes the mixing process smoother and helps create a lighter cake.
2. Don’t overmix your batter! Stir just enough to combine the ingredients. Overmixing can make your cake dense and heavy.
3. Use Dutch-processed cocoa for a richer, deeper flavor. It makes a huge difference in the taste of the cake!
4. When making boiled icing, don’t be afraid to take your time. Whisk it continuously, and make sure the sugar dissolves completely to avoid any graininess.
5. Let your cake cool completely before frosting it. If it’s still warm, the icing might melt, and you won’t get that nice, fluffy texture on top.
(FAQs) About Chocolate Cake With Boiled Icing
What is boiled icing?
Boiled icing is a light, fluffy frosting made by cooking sugar and water to a soft-ball stage and then whipping it into beaten egg whites. This process creates a glossy, airy texture that pairs perfectly with rich cakes.
How do I store chocolate cake with boiled icing?
Store the cake in an airtight container at room temperature for up to 3 days. If you need to keep it longer, refrigerate it for up to a week. For extended storage, you can freeze the cake without icing for up to 3 months.
Can I make boiled icing in advance?
Yes, you can make boiled icing in advance and store it in the refrigerator for up to a week. Before using, allow it to come to room temperature and re-whip it gently for the best consistency.
What type of cocoa powder should I use?
For the best flavor, use high-quality unsweetened cocoa powder. Dutch-processed cocoa can also be used for a smoother taste, but avoid using sweetened cocoa.
Can I substitute the egg whites in the icing?
While egg whites are essential for the texture of boiled icing, you can use pasteurized egg whites or egg white substitutes if you’re concerned about raw eggs. Keep in mind that the texture might vary slightly.
How do I prevent boiled icing from becoming grainy?
To prevent graininess, ensure the sugar is fully dissolved in the water before boiling. Also, avoid stirring the mixture while it’s cooking, as this can cause sugar crystals to form.
