Easy Microwave Mirror Glaze Recipe

I’ve already shared my Easy Mirror Glaze Recipe (made with only 5 ingredients!!), which helped make the mirror glaze technique much more approachable.

However, I wanted to simplify the process even further, and am now sharing a modified mirror glaze recipe that can be prepared using just a microwave!!!

Microwave Mirror Glaze needs to be a thing! I’m not kidding, this take roughly 5 minutes in the microwave to whip up. I’m 99% sure this is the simplest mirror glaze recipe out there!

I wanted to make a mermaid-inspired mirror glaze. To do this, I used some light shades of pink, purple, blue, and green.

In addition to making microwave mirror glaze a thing, I also want to make mermaid glaze a thing! So many goals, so little time.

There are a few things you need to know before you begin making your mirror glaze:

  • You must use unflavored gelatin; the sugar in regular jello throws off the recipe
  • I recommend using miniature white chocolate chips if possible, they melt the fastest
  • If you want to color the mirror glaze, be sure to use gel food coloring. It won’t throw off the consistency of the glaze like liquid food coloring
  • Be sure to pour the glaze over a fully frozen, very smooth cake. I prefer to pour this over cakes frosted with buttercream, but you an also pour it over frozen mousse.

Make The Mirror Glaze

Mix the gelatin in a bowl with 1/4 cup of water, and set aside to let it bloom while you begin the glaze.

Combine together the 1 1/2 cups of sugar, 1 cup of water, and 2/3 cup sweetened condensed milk in a heatproof bowl.

Heat for 1 minute at full power, and remove from microwave. Stir, and heat for another minute.

Next, add in the gelatin (it will be very firm), breaking it up into smaller pieces.

Heat for an additional minute, then add in the melted white chocolate.

Slowly stir, until the white chocolate is fully incorporated.  

The glaze should be perfectly smooth, and roughly 130 degrees F at this point.

If there are still bits of white chocolate, heat for additional 30 second intervals (stirring between), until all the chocolate is fully incorporated.

Divide the glaze evenly between four bowls. Color the bowls pink, purple, blue, and green.

Continue to stir occasionally to stop a skin from forming, until the glaze has reached 90 degrees, or is slightly above room temperature.

My glaze took about 20 minutes to cool to the right temperature.

Then pour drizzle in 2/3 of the purple, blue, and green glazes on top of the pink.

Once the glazes have cooled slightly, pour all of the pink into a large bowl with a pouring spout.

Although the traditional mirror glaze recipe involves more ingredients and additional equipment, this easy, 5 ingredient recipe makes the technique way more approachable.

I was shocked by how quickly I was able to make this, and how easy it was to do.

Traditionally mirror glaze cakes involve pouring the glaze over a perfectly smooth, mousse-covered cake.

I experimented, and found that you can easily pour it over a classic buttercream cake, as long as the frosting is extremely smooth.

I elevated my cake with a a small cake pan, then slowly poured the glaze on the cake.

Begin pouring the onto the center of the cake, then slowly work your way out to the edges. Once the cake is fully covered, sprinkle a line of edible glitter over the top.

Swipe a bit more blue onto the top of the cake with a large offset spatula, and sprinkle some edible glitter over the top.

Let the glaze continue to drip for about 10 minutes, then placed the cake in the fridge.

See? So easy!!! My cake was a three layer cake made with seven inch cake rounds.

This glaze recipe easily covered a cake this size, and I had plenty of leftover glaze.

It can be stored in the fridge in an airtight container, and reheated to be used in the future.

However, the glaze can develop a skin, so be careful!

Easy Mirror Glaze Recipe

This galaxy mirror glaze cake is made with the easier

Mirror glaze cakes don't have to be hard! This simple recipe only uses 5 ingredients, and can be poured over a chilled buttercream cake.

Prep Time 10 minutes
Cook Time 10 minutes
Additional Time 15 minutes
Total Time 35 minutes

Instructions

  1. Begin by mixing the gelatin in a bowl with 1/4 cup of water. Set aside to let it bloom while you begin the glaze.
  2. Pour 1 1/2 cups of granulated sugar, 3/4 cup of water, and 2/3 cup sweetened condensed milk in a heat proof bowl.
  3. Heat for 1 minute on high power in the microwave.
  4. Remove the mixture, and stir to incorporate the ingredients. Pour in the bloomed gelatin, and stir until it's fully dissolved. 
  5. Melt the white chocolate chips in microwave by heating it in 30 second intervals, stirring between each interval. Once the white chocolate is fully melted, pour the chocolate into the warm gelatin mixture.
  6. Carefully whisk mixture until fully combined.
  7. Continue to stir occasionally (to prevent a skin from forming), until the glaze has reached 90 degrees, or is just slightly warm to the touch.
  8. Divide the glaze evenly between four bowls. Color them different shades using gel food coloring. To create this galaxy mirror glaze, color them blue, purple, black, and pink.
  9. Pour each color of glaze back into one large bowl, alternating colors and drizzling the colors together as you pour them.
  10. Place a chilled buttercream cake (in the freezer at least 20 minutes, or the fridge for 1 hour) on top of a circular object smaller than the cake board, and set this on top of large baking sheet to catch the run-off glaze.
  11. Begin pouring the glaze onto the center of the cake, then slowly work out to the edges of the cake in a circular motion until the cake is fully covered.
  12. Let the glaze continue to drip for about 10 minutes, then scrape away excess glaze from the bottom of the cake board using a small offset spatula

Notes

One batch of this mirror glaze makes about 4 cups, which is more than enough glaze to cover one, eight inch layer cake.

If you plan to eat the cake within a few hours after pouring the glaze, leave it out at room temp.

If you pour the glaze in advance, store the cake in the fridge. Remove the cake from the fridge a couple hours before you plan to cut into it.

Make this mirror glaze ahead of time or save leftovers! Once it's made, wrap the bowl with plastic wrap store in the fridge for up to a week.

To use chilled glaze, heat the bowl in to the microwave for 15-20 second intervals until it reaches the right consistency

Use leftover glaze to top cupcakes, cookies, or even ice cream!

  1. you state that the glaze develops a film. So do you recommend glazing day of party or can you store it in the refrigerator over night and it be okay? Thanks!

  2. i used a swiss merinque buttercream and when i glazed it the glaze didn’t seem to want to stick to spots on the edges…any idea why? cheers!

  3. How long does the glaze keep, and how would you recommend reheating the glaze? I did a trial run today for a birthday cake next weekend, and I have a TON of glaze that I would love to just save and use later this week.

    1. It keeps for up to 3 weeks, and you can reheat it to reuse it! However, it can form a skin, so be sure to put some saran wrap on top of it when storing it in the fridge! 🙂

  4. We actually just did a cake with fondant instead of icing, and did the mirror glaze over it. It did pretty good, although was a little dark since we did chocolate flavored fondant, but otherwise, worked just fine and was a really smooth cover due to the fondant! 🙂

  5. Can you use colored candy melts instead of white chocolate chips? I would like to use white candy melts so was hoping that would work, any thoughts?

  6. Just made my third mirror glaze cake using your recipes. The first two were spectacular. I used the stovetop method for the glaze. This one I used the microwave, and wasn’t as happy with it. The temp never got up to the 130 that you mention initially, only about 90. At least it got to room temp much quicker! Then when I poured it, it was thin and had tiny bubbles, even though I had sieved it to get out any lumps. I think it will be okay, since I was making it for a friend’s kid and he wanted some white in it (the frosting is showing in places). Not sure if it was because I didn’t get it hot enough initially, do you think that the gelatin needs to be hotter to activate it? Anyway, I will probably stick to the stovetop method in the future. I’m sure it was operator error, just wondered if you had any ideas about what went wrong. I used your vanilla cake recipe and it tasted great (of course I had to taste the trimmings!!). Thanks for all of the ideas. I almost went into a sugar coma just looking at the S’Mores cake pics!

    1. I’m so sorry to hear that! Yah, i think it needs to be heated up a bit to ensure it sets properly! Happy that my vanilla cake recipe was a hit though 🙂

  7. Hello there! this is the first time I see a recipe that does not call for glucose and I wonder if, comparing a traditional recipe, you detect some loss of gloss in the final glaze? I would love to say goodbye to the glucose, not only because it’s a pain to measure, very messy to work with, but most recipes use a lot of it, and I keep having to order more and more 😉

    I am tempted to try it, but if you have input on the difference I’d love to know!

    also, have you tried to do a “spider web” effect with your method? that is also on my list to try soon

    1. it does lose it’s shine overtime, which is the downside to omitting the glucose! however, it makes this type of recipe so much more accessible to all the home bakers out there, which is why I’ve chosen not to use it. I have yet to try the spider web method, but I’ve been wanting to for a while!!

    1. I’d recommend just following the measurements to a T, and making sure your cake is fully chilled before you pour the glaze over it 🙂 best of luck!

  8. WooHoo! Worked on the very first time!
    However, it seems too opaque when finished even though it was VERY dark when mixed.
    Can I color the frosting to further darken to overall appearance?

    1. Hi Carla,

      So happy to hear that this worked on the first try for you! Usually I recommend using a light colored frosting under the glaze to help the colors pop, but it depends on what look you’re after and what color or colors you’re using! If you’re doing a single color and want to use the same color of frosting underneath, you can totally do that. Hope that helps, happy baking!

  9. I got a 10” round cake from Sam’s and had them cover it with buttercream. Then I will do the glaze. You said to freeze the cake but if I’m going to decorate and eat it in the same day the cake will not have time to thaw completely. Can I do the cake right out of the fridge and serve it that afternoon? Thanks.

    1. Hi Deidre,

      I’d try popping it in to the freezer for at least 20 minutes before pouring the glaze! The glaze will be a bit warm, and if the cake isn’t pretty well chilled the frosting can melt! I’m not sure what Sam’s clubs frosting is like and if it’s butter or shortening based, but I think a little bit of time in the freezer should do the trick! Please let me know how it turns out, I’m super curious!!

    1. Hi Bev,

      Do you mean before pouring the glaze?? Yes, I definitely think cakes need to be thoroughly chilled before pouring the glaze!! 🙂

  10. Definately! I cover cake in buttercream first, then freeze. Next day I do the mirror glaze, but if you want cake shortly afterwards, at least semi freeze it for a few hours. As I said, cake will thaw rather quickly.

  11. Hi, I froze the cake for a few hours that morning. Your recipe was easy and the glaze went on just fine. The shine of the mirror glaze only lasted maybe an hour then it went dull. I was sad. Next time I will use the karo syrup so it will stay shiny. Thank you for an easy recipe.

  12. This is my first time trying a mirror glaze and it ended up looking pretty cool (except the bald spot in the back). But it doesn’t have any shine to it, is that due to something with the temperature of the glaze? Thanks

    1. Hi Brandi,

      The shine usually has to do with the white chocolate you use! If you want a shinier look, you can try adding a bit less white chocolate next time. You also can make the glaze a bit warmer! It loses its shine as it cools. Hope that helps, happy baking! <3

Let me know what you think!
