This ultra rich chocolatey old fashioned boiled chocolate icing is ready in just 10 minutes! Cooked chocolate icing is crackly and fudgy and perfect for topping sheet cake.
Boiled Chocolate Icing
If you’ve ever tried chocolate Texas sheet cake, then you know just how delicious this boiled chocolate icing is. It’s an old fashioned sweet and fudgy favorite that you may remember Grandma whipping up on the stovetop.
It has all the same ingredients as a chocolate buttercream frosting, but is cooked on the stove instead of creamed together with an electric mixer. The sugar and cocoa powder dissolve with the melted butter while cooking, resembling the texture of a rich chocolate ganache.
Powdered sugar is sifted in then the icing is poured on top of your dessert, keeping it moist and adding a thick and glossy fudge finish.
Why I Love This Recipe
- Ready in 10 minutes. This cooked chocolate frosting recipe is made from start to finish on the stovetop in less than 10 minutes.
- Locks in moisture. After pouring the boiled chocolate icing on top, it will harden and create the perfect fudgy layer which helps to lock in the moisture in the cake.
Recipe Ingredients

- Cocoa powder: Make sure to use unsweetened cocoa powder since the majority of the sweetness will come from the powdered sugar.
- Powdered sugar: Adds a sweet flavor and thick texture. Make sure to sift the powdered sugar first, so that your icing isn’t lumpy.
- Butter: Using salted butter will add the best flavor. Cube it first before adding to the pan for easier melting.
- Milk: Used to help thin out the icing. Whole milk will add the richest flavor.
- Vanilla: A high quality vanilla extract will give you the perfect boost of vanilla.
How to Make Boiled Chocolate Icing
This cooked chocolate icing recipe is super easy to whip up on the stove in just 10 minutes. Follow the simple steps below to get started.
- Melt. Chop the butter into cubes and then add to a medium saucepan. Melt over low heat, then stir in the unsweetened cocoa powder. Let the mixture come to a light boil, then remove the pan from the heat.
- Whisk. Slowly whisk in the milk, vanilla extract and sea salt. Once combined, then whisk in the powdered sugar until dissolved and smooth.
Tips and Variations
- Cube the butter. Chop the butter into pieces before adding to the pan so that it melts more evenly and quickly.
- Sift the powdered sugar. To avoid a lumpy or grainy texture, make sure to sift the powdered sugar through a fine mesh strainer before whisking into the icing.
- For a crunchy variation with a rich, nutty taste, fold some chopped pecans or walnuts into the cooked chocolate icing. It adds great flavor and texture!
- Frost immediately. Add the frosting on top as soon as you take your dessert out of the oven so the icing can soak into the cake, brownies or Texas sheet cake cookies recipe. It will thicken quickly!
Ways to Use Cooked Chocolate Frosting
This boiled chocolate icing recipe works best as a spreadable topping, making it perfect for sheet cakes, brownies and bars.
I wouldn’t recommend using it for cakes with multiple layers because the consistency is a bit too thin and smooth. Stick with a traditional chocolate buttercream frosting for desserts such as a layer cake.
- Spread on top of a Texas sheet cake, white sheet cake recipe or strawberry sheet cake.
- Use in place of chocolate ganache for frosted brownies or homemade cosmic brownies.
- Use to frost a yellow cake, homemade vanilla cake or your favorite chocolate cake recipe.
- Pour over a bowl of homemade vanilla ice cream.

Yummy and simple!
Brings back the memories of my childhood. I now use this on my chocolate caramel poke cake. Mmm
That sounds delicious, glad you enjoy the icing!
This was easy to make and delicious, I poured it over a 9 x 13 pan of cooled brownies, turned out excellent
This is my go-to icing for brownies and for a wonderful chocolate caramel poke cake that I make! Yummy! It reminds me of the 80’s frosted brownies when I was a kid!
Sharla, my name is Rosie. Have you made this frosting recipe? It is very sweet. Also, is it possible for you to share your caramel poke cake recipe? I have been looking to make that recipe. If you can email it to me, I would really appreciate it.
Thank you in advance.

Hello Rosie, feel free to try our Better Than Anything Cake! which uses caramel and sweetened condensed milk to fill the ‘pokes’. I think you love it!
This chocolate icing is an absolute champion 🏆 My family and I absolutely adore it! Its rich flavor and perfect spreadability make it an unbeatable choice. I’m already planning to make it my go-to for all future desserts!
Delicious! I think this is the perfect amount for a 9×13… a good layer of frosting but not a “sickening “ amount. 👍😄
I used this icing to top my turtle pecan poke cake. It was the perfect icing! So delicious!
That sounds delicious! I’m so glad you love the icing Sharla!
This is exactly the recipe I was looking for! I’m so excited to make it! Thank you!
I hope you enjoy it Kristina :)
The absolute BEST chocolate icing EVER !!
I however omitted the salt since I used salted butter….
But that’s my families preference.
Years ago I used the recipe from the Hersheys Cocoa can for a cake with cooked chocolate frosting. This may be it! I want to bake it for our upcoming Tea Room. A comment I read said it wasn’t best for a layer cake. What do you recommend?
I’ve only used it for sheet cakes, but you could try with a layered cake. You’ll just either want to work very quickly to frost the sides or do more of a drip down the sides (since it won’t hold up as well as a buttercream).
Hi…can I pour this frosting on a cooled cake as well? I’d like to make a single layer round chocolate cake and have the icing drip down the sides but it has to be completely cooled for me to get it out of the pan.
That should work, however I haven’t tested this recipe for a drip cake. Typically I’ll just use a chocolate ganache like I do on this bundt cake: https://www.iheartnaptime.net/chocolate-bundt-cake/#recipe
When I was a little girl, my mom would make devil’s food cupcakes every Halloween with the best frosting. I’ve tried to find the recipe for 40 years, and this is it. Thank you for bringing back some great childhood memories from the 60s for me.
Oh, this makes us SO happy to hear Anita! Nothing like recreating nostalgic recipes :) Thanks so much for your nice comment and review!
