Chocolate Ganache FAQs
Luscious, rich, and velvety chocolate ganache is perfect to use as a frosting to adorn cakes, cupcakes, or brownies. Additionally, you can let ganache harden, scoop it into balls, and make it into truffles. Whatever you use chocolate ganache for, it’s sure to become a favorite, especially when you realize how easy it is to make!
What is Chocolate Ganache?
In its most basic form, ganache is a mixture of chocolate that’s melted with cream. Sometimes butter is added in place of some of the cream, and sometimes other flavorings, such as vanilla, espresso powder, etc. are used. Additionally, you can use different kinds of chocolate (milk, dark, or white) and switch up the flavor profile.
What is the Ratio of Chocolate to Cream to Make Ganache?
Depending on what you want to use the ganache for, there are different ratios of chocolate to cream. The ratios below are based on weight, not volume. For example, a 1:1 ratio of chocolate:cream would be 1 ounce chocolate to 1 ounce cream.
Pro Tip: Use a kitchen scale (you can find a relatively inexpensive kitchen scale that will do the job!) to measure your chocolate and cream to make ganache.
Ganache for Chocolate Truffles
Use a 2:1 ratio of chocolate to cream (2 parts chocolate to 1 part cream). Ganache for chocolate truffles is typically refrigerated until chilled (this type of ganache will harden when chilled), rolled into balls, and then each truffle is rolled in a coating, such as cocoa powder or chopped nuts.
Ganache for Frosting for Cakes, Filling for Cakes, or Whipped Ganache Frosting
Use a 1:1 ratio of chocolate to cream (the same amount by weight of chocolate and cream). At room temperature, ganache made at this ratio will thicken to the consistency of spreadable frosting.
This type of ganache can be used as filling or frosting for cake, or it can be whipped with a handheld electric mixer until light and fluffy. Once it’s light and fluffy, it can be piped on to cakes or cupcakes, or eaten as mousse. Once it’s chilled in the fridge, this type of ganache will harden.
Ganache for Glaze or Chocolate Fondue
Use a 1:2 ratio of chocolate:cream (1 part chocolate to 2 parts cream). Ganache made using this ratio of chocolate to cream works well as a glaze or fondue. It will thicken up a bit as it cools, but it won’t harden enough to be able to use it as frosting and it won’t set hard.
How Do You Make Ganache?
Chocolate ganache is very easy to make! Here are the steps:
- Chop the chocolate and place it in a glass or other non-reactive bowl.
- Heat the cream in a saucepan over medium-low heat on the stovetop until steaming and starting to bubble along the outside.
- Carefully pour the cream onto the chocolate and let the chocolate melt (don’t stir yet).
- Once the chocolate is melted, gently stir the chocolate and cream until smooth.
- Depending on what you’re doing with the ganache and what ratio of chocolate to cream you used, you may need to let the ganache cool to room temperature or refrigerate to chill before using.
Does Chocolate Ganache Harden?
Ganache with a 2:1 ratio of chocolate to cream will harden enough to scoop and roll into chocolate truffles when refrigerated.
Chocolate ganache made using a 1:1 ratio of chocolate to cream will thicken up to a spreadable consistency when cooled to room temperature, and it will harden when refrigerated.
If made with a 1:2 ratio of chocolate to cream will thicken as it cools, but it won’t harden enough to set.
How Long Does it Take for Ganache to Set?
Ganache typically takes about an hour to set in the fridge.
What if My Ganache is Too Thin?
To fix a ganache that’s too thin for what you want to use it for, melt your ganache in a double boiler (or a microwave) with more chocolate until it reaches your desired consistency.

Fudgy Guinness Brownies with Dark Chocolate Ganache Recipe
Ingredients
Brownies:
- 3/4 cup Guinness stout
- 10 tablespoons unsalted butter melted
- 3/4 cup honey
- 4 tablespoons sugar
- 1 teaspoon pure vanilla extract
- 2 large eggs
- 3/4 cup + 2 tablespoons unsweetened natural cocoa powder not Dutch-processed
- 1/4 teaspoon + 1/8 teaspoon salt
- 1/2 cup all-purpose flour
Ganache:
- 3 1/2 oz 80 to 85% dark chocolate chopped
- 2 tablespoons heavy cream
- 1 tablespoon unsalted butter
- 1 tablespoon honey
Instructions
- For the brownies, preheat the oven to 325F; line an 8 by 8-inch baking dish with 2 pieces of parchment paper so that it hangs over all 4 sides.
- Add the stout to a small saucepan over medium-high heat; cook until it’s reduced to about 1/3 cup. Beat together the butter, honey, sugar, reduced stout, vanilla, and eggs. Sift in the cocoa powder, salt, and flour, and stir to combine.
- Pour the batter into the prepared dish and bake until set along the outside, but a wooden pick inserted into the center comes out moist with a bit of batter, about 25 to 30 minutes. Cool to room temperature before topping with the ganache.
- For the ganache, melt the chocolate, heavy cream, butter, and honey together in a double boiler or microwave and stir together until smooth. Let the ganache cool to room temperature, and then refrigerate briefly to chill (just until it’s spreadable like frosting).
- Spread the ganache onto the cooled brownies and let it set before cutting and serving.
Helpful Tips
- Use a kitchen scale (you can find a relatively inexpensive kitchen scale that will do the job!) to measure your chocolate and cream to make ganache.
- Store the brownies covered at cool room temperature, or in the fridge if it's during the middle of summer. Let them come to room temperature before serving.
