Recipe: Chocolate mirror glaze

This is one of the pastry “secrets” that differentiate a home-baker from a “pro”. I’m talking about this super-shiny chocolate mirror glaze!

Recipe-Chocolate mirror glaze reflection

As you can see above, there is indeed a reason if it’s called “mirror glaze“, and I swear it is not a Photoshop trick! 🙂

Mirror glazes can be used to cover the top and the sides of modern tortes (entremets), where creams and mousses are prevalent. Covering a cake with a shiny glaze makes it instantaneously chic, professional-looking and also provides the “wow effect“!

And yet it’s so simple to make! Glazing properly, though, takes a bit of practice and a quick movement… I can see lots of practice cakes ahead! 🙂

Ingredients

50gWater
140gGranulated sugar
45gCocoa powder
95gHeavy cream
6gSheet gelatin (= 3 x 2g sheets)

Directions

1
Prepare the chocolate mirror glaze the day before using: soften the gelatin in cold water and in the meantime prepare a syrup by bringing the water and sugar to a boil on medium heat
2
Add the sifted cocoa powder and whisk
3
Brink the heavy cream to a boil
4
Incorporate the cream in the cocoa sugar syrup
5
Add the softened gelatin and whisk until it is dissolved. Store refrigerated in an airtight container overnight.
6
To glaze, make sure your entremet is cold enough (or better frozen), then melt the mirror glaze over a bain marie until it reaches 37°C (not more!). You can pour the glaze on a cake starting from the centre towards the sides with a circular movement. Keep that cake ring in place if you only want to glaze the top. It is advisable to place the cake on a wire-rack over a pan, so to collect the excess glaze

    Hi Rob, do you cover the cake in Ganache before glazing it?

      Hi Tanja, I would say that it depends on the cake. So far I’ve only used the recipe on a modern cake made of mousse, so the glaze sticks without problems. I wouldn’t probably use this glaze directly on a layer of spongecake; a simple shiny ganache might be better! 🙂

    Hi !! Can I make this glaze with same amount of granulated gelatine and butter+ whole milk instead of heavy cream?? Because I’m dying to try this glaze and couldn’t find heavy cream and sheet gelatine in stores…

      Hi Naj, for the gelatin there is no problem: you can replace sheet gelatin with granulated gelatin weight by weight. Now about the cream: “heavy cream” just means “unsweetened whipping cream”, usually with a fat percentage of 30%-35%, it’s quite common in supermarkets everywhere so it’s strange you can’t find it. But anyway, yes, I think you can replace cream with a combination of butter and whole milk. I’ll let you have fun with the conversion exercise: milk has 3% fat 97% water (to simplify), and the butter has 82% fat and 18% water. In the end you should have a mixture that is 30% fat and 70% water 😀

    Hi Rob!

    Any idea if this glaze will lose its shine if the cake is refrigerated after glazing?

    Thanks in advance!

      Hi Josiah, there is no problem in refrigerating it after glazing it: the cake has a mousse with eggs, so it needs to be stored in the refrigerator. On the other side, (books say) it’s bad to freeze the cake after glazing it, but I have never tried honestly.

    is it possible to obtain the same effect with white chocolate?

      Hi, I’ve never tried but it’s definitely possible. I would probably remove a bit of sugar since the white chocolate is sweeter than the dark one. 🙂

    Where do you get your gelatin sheets? I’ve checked many stores already including cake decorating stores.

      Hello Cynthia, that’s strange, I’ve never had problems in finding gelatin at literally ANY normal supermarket. Where are you from? Perhaps powdered gelatin is more common in your country? In the worst case, I’m sure some online specialty stores sell it.

    Does it get hard? The glaze is thick after storing it in the fridge for a few hours.

      Hi! The glaze gets thick in the fridge because it contains gelatin. To use it, you need to reheat over a bain marie up to a temperature of 35-37°C and it will be liquid (but dense), ready to be poured on a cake.

    I saw another recipe that make the glaze with chocolate plus cocoa powder , so I want to know if necessary to add chocolate or cocoa powder is enough

      Hello Aisha, depends on how the rest of the recipe is. There might be different variants. Honestly, if the recipe asks you to mix chocolate with water I would avoid it.

    Is it possible to use this as cookie glaze instead of tempering chocolate?

    Reply

      Hi Amy, honestly I wouldn’t use this to glaze cookies… it is a very liquid glaze that is perfect for smooth surfaces but would not cover well a rough surface like the one of a cookie. Moreover, you eat a cookie with your hands and you would get them dirty since the glaze sets but does not become hard.

        Thanks for the quick reply. I didn’t know if the glaze became hard enough. Sigh. Back to tempering.

    Hi what sort of cake can you mirror glaze? And what do you have to put under the glaze layer?

      Hi Emily! This is great for modern cakes, for example those with a spongecake inside and a mousse (with gelatin) on the outside. I used this glaze with my favourite cake: http://bit.ly/1c1nXBH
      For sure I think that using this glaze directly on a spongecake rather than a cream/mousse would not get you a good result.

    Hi Rob, I will try this one today! Just out of curiosity, is there a particular significance when you mention to prep this the day before using? I’m planning to make and use it within the day. Thanks!! I’ve become huge fan of this site. There’s something about the style and personality of this blog that’s really attractive and genuine!!

      Hi, Ana! Thank you very much! 🙂 I mention to make it the day before because it takes several hours to set (I don’t know how many) and it needs to set a first time before you melt it to use it. Perhaps 6 hours of fridge would be enough before using it. Good luck! 😉

    **Hi just a quick update**

    Success! Mirror test, passed.

    For those without easy access to gelatin sheets, I used 6g (same amount the recipe calls for) granulated gelatin dissolved in 20ml (since 3g of sheet gelatin absorbs 10ml of liquid) cold water. I let it set for 8 hrs before melting and assembly.

    For those wondering what other types of cakes to use this with… I used it to glaze a layered chocolate chiffon cake filled and covered with chocolate ganache, frozen for 5 hrs before applying mirror glaze. I could have kept it longer in the freezer but was pressed for time.

    Again, many thanks for this wonderful recipe!

      Hi Nisha, I haven’t tested any white mirror glaze recipe yet, so I cannot give you a trusted one. All I know is that you could make it with white chocolate or condensed milk (or both) with cream and sugar. And if you really want a shining white, you can use white colouring (titanium dioxide).
      I think any mirror glaze is shiny but still opaque enough to cover a dark-coloured cake.

    Why do you have to refrigerate the glaze then warm it back up again to use? Why not just let it cool to 37 then pour?
    I’m just confused as other recipes I’ve read say to let it cool then pour. But those recipes also use chocolate instead of cocoa powder.

      Hi, that’s a good question and I’m afraid I don’t have a scientific answer ready. I think it’s got to do with how the gelatin sets. And by experience, I once glazed a cake with a just made glaze and the result was horrible.

    I’m super excited because I’ve never made a mirror glaze with out having to use chocolate with condensed milk. So I can’t wait to try it! It completely makes sense, since rule number one is don’t mix chocolate with water, plus cocoa powder really blooms in warm liquid. Anyways, I was wondering did just the cocoa powder give enough color for a dark black finish? Or should I add food gel coloring? Thanks for the recipe!

      Hi! Yes, the cocoa powder is dark enough to give a perfectly chocolatey color!

      (PS: I recently discovered you can indeed mix water with chocolate… but it must be ENOUGH water to make the chocolate melt and create an emulsion)

      Hi, what is simple gelatin? 🙂 Is it the granulated one? If so, yes, you can replace weight by weight, but you’ll have to balance the recipe by removing the same amount of water used to dissolve the granulated gelatin (I’d say around 6g of water per gram of gelatin).

          The same amount as in the recipe. But you will have to dissolve it in a specific amount of water first, based on the instructions of your gelatin package. You will then have to remove that amount of water from the total water used in the recipe… makes more sense?

    Hi! I love this glaze I have used it many times! I usually always glaze my whole cake but tomorrow I am planning on doing just the top. I’m nervous because you can’t skim off the top like usual. Any idea how much to pour for a 10 inch cake? Just the top. Hope to hear! Thank you!!

    Hey! Me again! I figured it out and I think it’s about 3/4 of a cup to glaze just the top of a 10 inch cake! My next question is it is ok to store the remaining glaze in the freezer to use later? Thanks!!!

      Hi Emily, I think you can. Gelatin has a tendency to release water when thawing, but in this case I think the result is perfectly acceptable. 🙂
