This simple and easy recipe with my tips and troubleshooting will show you how to make a mirror glaze perfectly every single time.
Have you seen these mirror glaze cakes recently? Wow! It’s got to be the latest craze in the cake world. Mirror Glaze, aka Shiny Cakes.
There is a Russian confectioner on Instagram that has these cakes, and they blow my mind every single time, especially those galaxy mirror glaze cakes. These have been on my wishlist for a while, and I wanted to make one and share the recipe with you.
What is a mirror glaze?
Mirror glaze is white chocolate and gelatin-based and is often used on entremets. This glaze, when poured over a cake, gives an ultra-shiny appearance like the surface of a mirror. Hence the name mirror glaze. And, although it consists of chocolate, very little of it sticks to the cake, so it does not affect the flavor of the cake much.
Ingredients and substitutes
- Gelatin – This is what helps the mirror glaze stick to the cake. So, yes, a critical element. Use good-quality non-flavored gelatin for the best results.
- Glucose – This helps prevent the mixture from crystallizing. If you can’t find glucose, you can use light corn syrup as well. But you do need one of these two.
- Sugar – Yes, I know condensed milk is sweet, and then again, we have sugar, but this recipe is not about the calories; it’s about achieving that mirror glaze effect.
- Condensed milk – The main ingredient in a mirror glaze is condensed milk, which, when combined with chocolate, water, and gelatin, gives it that reflective, mirror quality. And, because it uses gelatin, the result is a soft glaze, not hard like chocolate. You can use homemade condensed milk, too.
- White Chocolate – We use white so we can play with color and achieve all those different colors, but you can use dark chocolate too! Of course, once you add dark chocolate, there is only one color – brown – so you won’t be able to make the blue, reds, and all those fancy colors.
Mirror glaze cake
- Have all your ingredients ready, so you do not leave anything out.
- Add half the water in a small bowl with gelatin and let it soak for 3 to 5 mins to bloom.
Pro tip – It is important that the gelatin soaks well, or it can give you a very grainy glaze.
- In a heavy-based saucepan, add glucose, sugar, condensed milk, vanilla extract, and remaining water. Stir well and let it come to a boil over low to medium heat.
Pro tip – A heavy-bottomed pan will prevent the condensed milk from scorching at the bottom. If it does, do not scrape it, as it will ruin the taste and texture of the glaze.
- Once all the sugar has dissolved and the mixture has come to a nice, slow boil, take it off the heat. Let it rest for a minute before you add the white chocolate.
Pro tip – The reason we let it cool for a minute is so that the white chocolate does not split as soon as we add it to the boiling mixture. - Next, add the soaked/bloomed gelatin. Let it melt.
Pro tip – The heat in the liquid mixture should be enough to melt the white chocolate and gelatin. If not, use an immersion blender for just a few seconds. - Strain the mixture through a fine mesh sieve or mesh.
Pro tip – We strain to remove any undissolved gelatin or unmelted chocolate. - Color the glaze – Divide the glaze into the number of colors you need for your project. Color the glaze with food gel colors. Let it reach almost room temperature, between 90 and 95°F.
Pro tip – You don’t want the glaze too hot, as it can melt the dessert, but also, not too thick. It should be a pouring consistency. Otherwise, it will not flow down the dessert.
- Pouring the glaze – Place the frozen cake on a cooling rack (wire rack) over a large plate or baking sheet/tray so the excess glaze will drip down on the cake. Pour the glaze in a circular motion, starting with one or two colors based on the desired effect. Use an offset spatula to blend the colors.
Pro tip – If you have air bubbles in the mirror glaze, hold the glaze a bit higher so the bubbles disperse before the glaze drips down to the cake.
What cake is best to use for mirror glaze cakes?
Ideally, you want something that has a smooth finish. If you have a bumpy cake, the glaze will show those bumps and dips. So it’s good to have a smoothly frosted cake for the best results. Also, it’s best on frozen cakes because the gelatin sets as soon as it hits the chilled cake. You can also use mirror glaze on frosted cakes, and cheesecakes. It works best on entremet and cakes with mousse and Bavarian creams. And, yes, you can also use it on layer cakes as long as the outside is smooth. Today, I used a chocolate mousse cake with a chocolate torte insert. Here are a few of my mousse recipes that will work well for the mousse cake with mirror glaze.
- Classic Mango Mouse – vegetarian mango mousse
- Vegan mango coconut cream mousse (vegan, vegetarian)
- Classic strawberry mousse
- Classic chocolate mousse, Eggless, or Vegan chocolate mousse
- Blackberry mousse (eggless)
- Chestnut mousse (eggless)
Frequently asked questions
Mirror glaze has chocolate in it, so ideally, it will set as soon as it hits the frozen cake. You want the glaze to drip completely; clean the edges on the bottom with a clean knife or spatula. Carefully transfer the cake to a cake board or a serving platter. Before the cake sets, it is essential that you do not touch the glaze.
If you use a cake with buttercream frosting, it does not have to be frozen, but it does need to be smooth. The glaze does not cover any blemishes, so any imperfections will show through. A mousse-based cake needs to be frozen before you glaze it. Mousse is usually set in a silicone mold and often has a smooth surface that works well with the glaze.
Glazes made with perishable ingredients like this one with condensed milk should always be refrigerated.
If the glaze is poured over a mousse-based cake, then the mousse is also made of perishable ingredients. Mousse, if left at room temperature, will start to soften. So, yes, it needs to be kept in the fridge and is usually served cold.
On the other hand, if you pour the glaze over a frosted buttercream cake, you can leave it out on the counter for a few hours, and it will be ok.
The only ingredient in the mirror glaze that’s not vegetarian is gelatin, which is usually animal or fish-based. If you substitute the gelatin for vegetarian gelatine or agar-agar, this can be a vegetarian glaze. You can find my recipe for vegetarian mirror glaze here.

Notes
-
- Plan this dessert in advance so you have enough time to do the necessary steps.
-
- Make sure the cake is frozen for a few hours so the glaze solidifies as soon as it hits the cold cake.
-
- The temperature of the glaze is important. You need the glaze to be a pouring consistency at a temperature between 90 to 95 F.
-
- Glazes made with perishable ingredients like this one with condensed milk should always be refrigerated.
-
- Plan the colors you are going to use in advance and take note that white chocolate, gelatine, and condensed milk are not white. So, you are starting off with an off-white base. Some colors don’t do well with this base. You may need more.
-
- Mirror glaze is not white, so if you need white, you will need to use white gel food color, also called titanium oxide.
-
- Once glazed, the cake must be left in the fridge to thaw so the moose is not too cold to cut.
Troubleshooting
- My glaze is too thick, so it won’t pour. You need the mirror glaze to have a pouring consistency at a temperature between 90 and 95 F. Before you attempt to pour, take a ladle and check the consistency. If it’s not pouring, then add a few tablespoons of water. Be careful when adding water, as you cannot make it thicker once you’ve diluted it.
- My glaze is too thin – If you have not boiled the mixture enough when preparing the mirror glaze, it will be too runny and will result in a very thin coverage. Also, if you have not waited long enough after making the glaze, the gelatin will not have gelled. I suggest placing the glaze for 3 to 5 minutes in the fridge or waiting a little longer at room temperature. This will help thicken it up a bit – then try again.
- The glaze does not stick to the cake – It just slips off. Condensation on the cake can cause the glaze to slide off the cake rather than stick to it. If the cake is frozen, wipe off any excess moisture from the cake and try it again. If you live in a place with high humidity, I highly recommend glazing immediately, as soon as the cake is out of the freezer, before it has had time to condense. Additionally, setting the air conditioner to high for those few minutes might also help.
- My cake started to melt as soon as I started to glaze it – The glaze needs to be at room temperature. If you use a hot or warm glaze, it will melt the frozen cake, causing the cake to have a melting effect.

Please share tips to transfer the mirror glazed cake on to a cake board, to be packed in cake box.
I did a small tester cake followed by a galaxy birthday cake for my son’s Star Wars birthday. The glaze turned out great both times with this recipe and the pro tips were especially helpful as I had never tried this before. All of the party guests were wowed!
Thank you so much, Jennifer, for the lovely feedback. I am so happy to hear your cake was impressive
Worked Fantastic! Have been wanting to try a mirror glaze but was intimidated by gelatin sheets. Came across this recipe and decided to give it a try. Made a 2 tiered layered cake for my father in law’s birthday with buttercream icing. Used this glaze recipe and it turned out beautifully! Thank you for posting the cake was a hit!
Thank you for the lovely feedback, Jennifer. So happy that worked great for you.
How big of a cake will this cover?
Will white chocolate melts work?
Should be good for an 8 or 9 inch cake
Hi Veena, would this recipe work if I use white compound chocolate instead of coverture chocolate.
Yes, Namrata. It should work. Though compound chocolate is not very tasty. I highly recommend using a chocolate bar instead.
It does say when to add vanilla.
Hey, Wendy, yes, you can add the vanilla at the last step with the chocolate or as I suggested in the post, to the saucepan with condensed milk. Thanks, I just updated the post.
can you pipe over top of the glaze once it sets?
I have not tried to pipe on it. The glaze when dried is still tacky – the gelatin effect. Perhaps something light like a chocolate writing or such.
Turned out great! The only thing I changed was I added a bit of lemon emulsion and some white food coloring before adding colors. The white made it more opaque and not so translucent. I would love to post a picture but it won’t let me.
Thank you, Kendall. Lemon sounds delicious. Yes, I would love to see it. You can share with me by uploading an image here on Pinterest – you will see – add photo – click and upload it will go below my image. And don’t forget to tag me on Instagram or Facebook @veenaazmanov or #veenaazmanov. Thanks
Thanks for the receipe and for detailed instruction! I made a buttercream cake and the glaze worked out perfectly!! Please let me know where I can share the photos of my cake..
I am so happy to hear that this worked well for you. You can share the photo with me in my Facebook group Thank you
Hi! Website lists 150 gram of sugar but the print version says 300 gram (it’s the only measurement that’s different). Also, print version says 1 tsp of vanilla. Just trying to clarify what to use.
Sorry, Lyndie – I think yesterday I must have made some error while working on that post. Thanks for bringing it to my attention. I have corrected it now.
Wonderful recipy tnk u so much???
Thank you, Shanaz
Hi Veena, my mirror glaze cake came out very nice. But it seem to loose the shine once it dried. What am I doing wrong.
Hey Gerda. Is it tacky when you touch it? The shine comes from the combination of gelatin and condensed milk. Perhaps the glaze was too liquid?
