Hey guys, it’s Ro! Today we are gonna be making something that I have got a ton of requests for Today we are gonna be making a mirror cake

For those of you who aren’t familiar with a mirror cake, it’s a very specific type of glaze that’s very reflective And I’ve also been getting a lot of requests for a galaxy themed cake So I’m gonna combine both of those today and I’m gonna be making a galaxy mirror cake Let’s get started! The things you will need will be: 2 6” round Vanilla Cakes, 8 ounce of white chocolate, the type that I’m using is couverture, I’ve tried other types of chocolate and it just didn’t work as well 1 cup of sugar, 1/2 a cup of cold water, and then a separate measurement of water which will be 1/4 cup of water

1/2 a cup of light corn syrup, 1/2 a cup of sweetened condensed milk, 5 teaspoons of powdered gelatin, some vanilla buttercream frosting, food coloring, depending on what colors you want to make your cake, you can make these any colors, but because I’m making a galaxy cake, I’m gonna be using black, white, navy blue, electric blue, purple and pink And then lastly, this part is optional, but I’m gonna be adding a little bit of edible, black disco dust The first thing that we’re gonna do is level our 2 cakes Remember, you can use any type of cake that you’d like, but I am gonna be using vanilla because, I love vanilla! And I’m just putting it on top of a piece of parchment paper so that it won’t be on top of the table and I’m taking a cake leveler… It’s got a little wire in the middle and little feet, so you just put the feet down and then you saw back and forth Then you’re gonna take off the top, which is the best part, it’s like the muffin top! So good, you can crumble this up, put it in a little container and make cake pops with this

So you’re gonna save this for another treat The top is leveled, now we are gonna cut it in 1/2 So with our little cake leveler, I’ve moved it down a few more notches, and lined it up so that it’s hitting about 1/2 way through, doesn’t have to be perfect There we go! Now you’re gonna do this to your other cake Cakes are leveled, the next thing that we’re gonna do is assemble our cake

In front of me I have a little turner, wika-wika-wika! Which makes it a little bit easier to frost And, a little cake board I got this one at Michael’s, but you’re just gonna need something that will be the same size as your cakes Then over here I’ve got some vanilla buttercream frosting that I put into a little plastic baggie and I just cut the end, so you just put a little bit in the center, so that your cake won’t move Pick up your first layer, place it in the middle, and then, we’re gonna cover the top with your frosting

Get out of here you fly! You freaking fruit fly! You’re not allowed! I’m just gonna lightly smooth Then you’re gonna put on your next layer, and then frost again Smooth it out, then for the top layer, we’re actually gonna flip it upside down, so that the baked bottom is on the top After your cake is assembled, I just popped mine in the refrigerator for about 20 minutes to set and chill again before I frost And I’m just gonna cover the whole cake, the top and the sides with frosting

Cake is totally covered and frosted Now using a big offset spatula, I’m gonna smooth it out So you’re just gonna plant, your spatula here, and try not to move the angle And then, spin the cake around it will create a really smooth finish all the way around If it’s not perfect the first time around you can swoop it around again! Then on the top I’m just gonna smooth it out

And now I’m gonna spin it around, pushing the frosting out to the edges And you’ll see that a little bit of frosting is hanging over then end, and that’s OK, because then we’re gonna turn our spatula like this, and scoop it up Our cake is completely frosted and now we’re gonna set this in the refrigerator for 2 hours to completely set and chill And while it is setting, we are gonna make our mirror glaze! Which is what makes our mirror cake, a mirror cake! The first step to making our glaze, is we are going to bloom our gelatin So you’re gonna pour all of the gelatin into the 1/2 a cup of cold water, and then with a spoon we’re gonna stir together, and you’ll know that it’s ready when it looks like applesauce

And then I’m gonna set it off to the side for about 5-10 minutes to bloom Then, in a medium sized saucepan, we are gonna add our 1/4 cup of water, our light corn syrup, and our sugar Then I’m gonna whisk together until well combined and then take this mixture over to the stove Turn your heat to medium-low and cook for 7-8 minutes, your mixture will slowly begin to boil, and dissolve your sugar Once ready, turn off the heat, and go back to your baking station

Our mixture is hot and fresh off the stove, so be very careful, this saucepan is really hot still Now we’re gonna add our bloomed gelatin Then we’re gonna whisk together Next we are gonna add our sweetened condensed milk, and whisk together one more time Our mixture is ready, and now we are gonna pour it into a bowl with our chocolate

And this is still hot, so I’m gonna be using an oven mitt Since this it’s still hot, we’re gonna let it sit for 2-3 minutes, right here, and let it melt the chocolate Our chocolate has softened, it’s ready to mix, I’m gonna be using a handheld emersion blender You can use just a regular hand mixer, that’s fine But I really like to use this type of blender for chocolate because it gets things very smooth

You’re just gonna turn it on, and mix it up Ha-ha-ha! The power! Our mirror glaze is now all mixed, and over here, I’ve got another medium sized bowl, with a strainer on the top! And we’re just gonna pour the mixture through the strainer, to catch all the little air bubbles or chunks Anything that wasn’t smooth I’m letting it drip in there, because I want all the mirror glaze I can get! Ha-ha-ha-ha! Now we’re gonna split it between 5 bowls for our different colors And now we’re gonna color our mirror glaze

And this is where you can pick any colors you’d like, if you’d like to make a rainbow mirror cake, or a tie-dye mirror cake, you can pick any colors So for this one I’m gonna be adding a little bit of navy and a little bit of black Here I’m gonna be adding 6 of electric blue and 2 navy blue For this one, a couple drops of pink A little bit of purple, and a little bit of electric blue! Then over here, I’ve got 5 different spoons, and now we’re gonna mix them together

Be sure to move quickly, as they set fast My colors are all done and I am so excited because now it is time to pour these over our frosted cake Our cake is ready to become a mirror cake I just took it out of the fridge and I placed it on top of a little vase, I had a very small vase If you don’t have a little vase, you can use a little cup, whatever you have around your kitchen

And then, I placed it on top of a cookie sheet, lined with a piece of parchment paper, so that when we’re pouring the glaze, it will be easy cleanup Over here I’ve got my base glazes, so whatever color you want to use for the base coat I’m gonna be using the dark space color, and the darker blue I’m going to pour the blue into the space blue Then, using the spoon, I’m gonna give it a gentle swirl, but I’m not mixing it together, just giving it a little swirl

And then we’re gonna pour it on the top of the cake, and let it drip all over the sides We’re gonna cover the whole cake with this base coat of glaze I’m gonna start over the top, and it’s just gonna drip over the sides Oh you guys! Look at that! If you were just doing a single color or a two-tone color, you would just stop here and let the cake set, but we’re gonna be adding some extra details to really look like the galaxy! Another helpful tip is you’ll want your glaze to be at about 90 degrees temperature, I have a little candy thermometer so you can stick it into the glaze to make sure that it’s 90 degrees, if it’s hotter than that, it’s gonna be too thin and not stick to your cake If it’s colder than that, it’s gonna be a little thicker and a little clump-ier, it won’t spread as even

And if they cool down, you can just pop ‘em in the microwave, and stir ‘em up to make them warm again I’m gonna take the lighter blue, with a spoon and I’m just gonna pour across to get some cool detail And a little purple, we-oooo! Just have fun with it, you can make it look however you’d like Then the pink! Once you’ve got your colors on the cake, now I’m just gonna take a very big spatula, and very gently brush the top to kind of evenly blend the colors

I’m gonna be moving with the streak Just be very, very gentle, you don’t want to expose the frosting Over here I’ve got the black disco dust, and a little paint brush And I’m just gonna dip the ends into the dust, and then I’m just gonna flick it on top of the cake It’s adding this really cool shimmer effect

It looks so cool, it looks shiny, and shimmer-y Lastly, using the same brush, we are gonna dip this into a little bit of white food coloring over here, in this little bowl And we’re gonna do a little splatter! Just like that! It’s a little bit messy, but it’s very fun! Because we need stars in our galaxy! Yeah! Now we’re gonna let our cake sit for about 20 minutes to let the excess glaze drip off After your mirror cake has set you can transfer it onto a serving tray, or a serving plate And the bottoms are very, very sticky

So if you’ve transferred it and there are any imperfections on the bottom, this part is totally optional, but I am gonna be adding a little traditional cake border, all the way around the bottom edge, to hide any imperfections I’ve just got some buttercream frosting with a star tip at the end Ta-da!

  1. My son is turning 9 in a couple of weeks and really wants this cake. But we hate buttercream. And I’ve never made a cake like this at all before. I just make the Box cakes and use the Box frosting unless I’m making a sugar glaze for a lemon pound cake. Can you help?

  2. I made this cake and I’m only 14! It turned out alright but I didn’t have anything to smoothe the buttercream with. But otherwise it turned out really good! Can’t wait to eat it later!!
