Chocolate ganache is a mixture of dark chocolate and heavy cream that sets into a glossy, smooth coating or filling depending on how you use it. It takes about 20 minutes, uses three ingredients, and works as a glaze, a frosting, or a truffle base — which makes it one of the most useful things you can learn to make. Once you’ve done it once, you’ll reach for it constantly.
What makes this version work
Two things matter most here. First, chopping the chocolate finely — pieces no larger than a pea — gives the hot cream maximum surface contact, so the chocolate melts evenly without needing extra heat that could cause graininess. Second, the two-minute rest before you stir is not optional. Pouring the cream and immediately whisking traps air bubbles and can cool the mixture unevenly before the chocolate has softened. Letting it sit undisturbed means by the time you start stirring from the center outward, the emulsion comes together in under a minute with almost no effort. The butter goes in last and gives the finished ganache its shine and that slightly soft, yielding texture when it sets.
Troubleshooting
- Ganache looks greasy or separated: The fat has broken from the emulsion. Add one tablespoon of warm cream and stir slowly from the center — this usually brings it back together. Avoid adding cold cream, which makes it worse.
- Ganache is grainy or gritty: The chocolate got too hot or was stirred too aggressively while still cool. Next time, make sure the cream is just simmering, not boiling, and let the rest period do the work before you touch it.
- Ganache set too firm before you could use it: It cooled too quickly, often on a cold counter or near a draft. Reheat it gently in 10-second bursts in the microwave, stirring between each, until it loosens. A double boiler works too — just keep the heat very low.
- Ganache won’t thicken for spreading, even after cooling: The cream-to-chocolate ratio may be off if you measured by volume rather than weight. For a spreadable consistency, weight measurements are more reliable — use a kitchen scale if you have one.
- Surface has a dull, streaky finish after setting: This usually means it was disturbed while cooling, or the bowl had residual water in it. Make sure all equipment is completely dry before you start, and once the ganache is poured, leave it alone.
Keeping it fresh
Ganache keeps well in an airtight container in the fridge for up to two weeks. Press a piece of plastic wrap directly onto the surface before sealing the container — this prevents a skin from forming. When you’re ready to use it, let it come to room temperature for 30 to 45 minutes; it will soften on its own without needing heat. For longer storage, ganache freezes well for up to three months. Thaw it overnight in the fridge, then bring it to room temperature before using. Skip the microwave for thawing — it heats unevenly and can cause separation. If you’re making it ahead for a specific project, ganache made one day in advance and stored at room temperature overnight (in a cool kitchen) will be at the ideal spreading consistency the next morning.
Classic Chocolate Ganache
Equipment
- 1 Double boiler or a heatproof bowl over a saucepan
- 1 Whisk
- 1 Spoon
- 1 Measuring cups
- 1 Silicone spatula
Ingredients
Ganache Base
- 250 grams dark chocolate finely chopped, preferably 70% cocoa
- 250 ml heavy cream fresh
- 14 grams unsalted butter room temperature
Instructions
- Prepare your equipment by setting up a double boiler, or use a heatproof bowl placed over a saucepan with simmering water.
- Finely chop the dark chocolate and place it in a heatproof bowl.
- In a small saucepan, heat the cream over medium heat until it just begins to simmer, not boil, with small bubbles forming around the edges and steam rising.
- Pour the hot cream over the chopped chocolate. Let it sit for two minutes to allow the chocolate to begin melting.
- Begin stirring the mixture slowly with a whisk, starting from the center and gradually working outward. Continue until the mixture becomes smooth and glossy.
- Add the butter and gently stir until fully incorporated, ensuring the ganache is smooth and shiny.
- Allow the ganache to cool slightly before using it as a glaze, or let it thicken at room temperature to use it as a filling or frosting.

FAQ
Can I use chocolate chips instead of a bar?
You can, but the results won’t be as smooth. Chocolate chips contain stabilizers that resist melting cleanly, so the ganache may have a slightly thicker, less glossy texture. A chopped bar of good-quality dark chocolate gives you the best finish.
What if I don’t have a kitchen scale — can I measure by cups?
You can get close, but ganache is sensitive to ratio, and volume measurements for chopped chocolate are inconsistent depending on how finely it’s chopped. If you only have cups, use roughly 1.5 cups of finely chopped chocolate and 1 cup of cream, and expect you may need to adjust.
Does the chocolate percentage really matter?
Yes, it affects both flavor and how firm the ganache sets. A 70% bar gives a deep, slightly bitter flavor and a firmer set. Lower percentages like 50–60% will taste milder and produce a softer ganache, which may not set firmly enough for truffles without chilling.
My ganache is ready but my cake isn’t — how do I hold it at the right consistency?
Leave it at room temperature, covered, for up to two hours. If your kitchen is warm and it starts to loosen too much, set the bowl over a larger bowl of ice water and stir gently for a minute to firm it back up.
Can I make this dairy-free?
Full-fat coconut cream is the most reliable substitute for heavy cream in ganache. Use it in the same quantity and the process is identical. The flavor will have a mild coconut note, which works well with dark chocolate.
How do I know when the ganache is the right temperature to pour over a cake?
It should feel just slightly warm to the touch — not hot — and flow off a spoon in a slow, steady ribbon. If it runs off too fast and thin, wait five more minutes. If it’s too thick to pour cleanly, warm it briefly over a double boiler.
