This technique works best with an icing containing at least one-third butter, but can be done with an all shortening icing with slight modifications in the chilling steps.
|
1. To begin with, there are some tools I consider “must have” items: |
|
2. Trace the outline of the pan [top side down] onto a sturdy surface, such as a piece of foamcore, cardboard, or for a more permanent use, masonite. |
|
3. Cover the outline with a piece of parchment paper about 1 to 2 inches larger than the pan’s outline and tape securely so that there are not wrinkles. Some people have had success using acetate instead of parchment. |
|
4. Using a very smooth icing, “ice” the area of the circle, extending the icing about 1/4″ past the outline; any extra icing will be removed later. Apply the icing about 1/4″ thick. |
|
5. Once chilled, remove the board from the refrigerator and place the “top” cake layer top down on the iced circle, centering is in place. Fill and add aditional layers. Here I have used only 2 layers, but normally I would have torted the layers into four. |
|
6. Lightly crumb ice the sides of the cake and chill a few minutes if desired before applying the final coat of frosting. Apply the final coat of frosting to the desired thickness using a spatula or large icing tube. |
|
7. Place the cake on the turntable. Dip the spackling knife in hot water and dry with a paper towel. Hold the blade against the side of the cake at about a 45 degree angle and reach the other hand around the back until it is near the hand holding the knife. |
| BE SURE THE SPAKLING KNIFE IS TOUCHING THE PARCHEMENT or else there will be a line of icing pushed out beneath it. |
|
8. SLOWLY turn the turntable one full rotation WITHOUT STOPPING. Inspect the side so the cake. If it is not smooth to your satisfaction, repeat step #7 again. If a small amount of icing has pushed under the blade, simply scrape it away before step #7. |
|
Smooth any icing build up over onto the “bottom” of the cake with a small angled spatula. When the side are smooth to your satisfaction, carefully cut the parchment paper loose from the board ALL THE WAY AROUND THE CAKE using an Exacto Knife. Carefully return the cake to the fridge for about 10 to 15 minutes to firm the icing [all shortening icing may need to be put in the freezer]. |
|
9. Prepare the final cake board by smearing a few strokes of icing on it. Remove the cake from the fridge, center the board and quickly “FLIP” the cake over. REMOVE the cardboard, but leave the parchment in place and return to the fridge for about 10 minutes. |
|
\10. Carefully remove the parchment…..you should have a beautifully iced cake with perfect edges and a very level top. |

My icing is:
3 sticks room temperature butter
1 cup shortening [avoid transfat free shortenings]
2 pounds powdered sugar
1 tablespoon clear vanilla
Mix butter and shortening until well blended.
Add sugar all at once and mix on low…mixture will be dry at first, but will become smooth as it mixes.
If too stiff, warm a few tablespoons milk in the microwave until very hot and add a tablespoon or two.
Add vanilla.

Great technique! Would this work with IMBC or other non-crusting bc like cream cheese bc?

With IMBC or SMBC what worked for me is:
1) crumb coat
2) place in the fridge
3) spread 2nd coat of b/cream generously making edges as crisp as possible
4) place in the frdge again
5) when cold take a bench scraper and scrape away all the excess cream
This leaves the cake smooth as can be.
I have not tried this with the butter/crisco frostings

Does it work good on color icing? or will it change the color with the heat of the spatula ?
Thanks!

I am a Wilton Cake Decorating Instructor and I just want to thank you for sharing this with my students. Last night was the last night of class and one of my students used this icing method and I never seen a more flawlessly iced cake. It was smooth as copy paper.

I love this. I just bought my spackling knife today!!!! Could it work with whipped cream? I need to make a cake with whipped cream frosting and I would love to try this. I have such a hard time getting my frosting to come out smooth and neat. Thanks, Dawn

I try to avoid BC as I find it so hard to get a crisp finish that you get with fondant. But lot’s of people prefer the tast of BC now I can’t wait to try this so I can be a convert. Thanks soo much for sharing

I don’t like the taste of “american buttercream”, so can I use this with cream cheese buttercream? I have a recipe that crusts.

Does this work the same way with PC’s ganache recipe? I love the crisp edges that PC has on their cakes, but the ganache would have to be flawless to begin with! If it works, this upside down method may be the answer to all my prayers.

Jackie: Tried this today, but had problems. Sides looked great, but when peeling parch paper I lost a chunk/edge off the top. Did I not let it set long enough before putting the cake on iced circle? My cake was also pretty heavy to be flipping (4-9″rounds each torted with filling.) Could the weight have played a role in my problem? The size made it very difficult to flip. (My daughter was waiting for it to hit the ground, I was shaking after it was safely right-side up.) Also have you done this with square cakes? I’ve got a square cake I’d like to try it on next week. I’m sure my problem was operator error. Any thoughts to steepen the learning curve would be greatly appreciated. -wakemaven

Has anyone ever tried this with a large (9×13 or 11×15) cake? Am I looking for trouble?

I’ve tried this twice. nothing but disaster for me. I ended up scraping ff the icing and reapplying as usual. 5 minutes, done, smooth. I’m sure this works for others, but I’m obviously doing something wrong.

I tried this for the first time tonight, and it took FOREVER! What I could normally get done in a few minutes took me hours to do. I will admit, however, that I LOVE the technique of using the spakling knife. My cake had extremely smooth sides…but…once I took the paper off the top, it was all uneven and the buttercream stuck to it (there is no shortening in my recipe and I let it chill for over an hour). I don’t think I’ll be trying this one again (it’s faster to just smooth out the top on my own), but I will continue to use the spakling knife on the sides!

This is just what I needed. I am going to give this a try & keep doing it until I perfect it. Do you think this would work for sheet cakes as well? hmmm I’m gonna try. Thank yo so much for sharing

I’d sure like to understand the purpose of some of the chilling steps. Some of them don’t seem to serve an obvious purpose. And, when does the icing get a chance to level out on the top? You chill it before setting the cake on it & every step of the way; is it still soft enough to flatten against the top of the cake? Understanding the purpose of each step might help prevent failures. Thanks for any clarifications anyone can provide.

Also curious about a square cake. I have a 4 tier square wedding cake to make in June. I will be doing a smaller version of it for my daughters birthday this weekend…. Any heads up doing this with square tier cakes would be great! Thanks!

how much does your buttercream recipe make?

this came out great for me! but only when i use homemade buttercream. Which is sad for me because my family and friends prefer store bought frosting(yuk!) because its “cheaper”
Anyone have any tips on how to do this with store bought frosting? Like is there anything i could add to the store bought that would make it so the frosting doesnt stick to the parchment paper??
Also, after the cake was done and ready to eat a few bubbles surfaced on the top? why would it do that and any tips on how to prevent it?

Just tried this method for the 1st time. I did it with dark chocolate ganache…worked out so well! I was able to skip some stages due to not having to chill the ganache so often. Loving it!

The BC looks like a true white color…is it really that white? I’m doing a wedding cake next week and need the true white color out of BC My recipe is 1 c butter and 1/2 crisco, vanilla, meraingne(? spelling) powder and milk. Please reply quickly.

NormaJ: replace your butter with white Crisco in your recipe for true white buttercream. If using butter, your buttercream will never be pure white, because of the yellow color in the butter.

I have been working on this since i started and can’t get the nice edge. Thanks for sharing. I’m definitely trying this on my next cake.

Woohoo!! I’ve been saving your tutorial in my favorites for eons – but because I’m a scardy cat and set in my ways, I took way too long to try it. But… be still my beating heart… I’ve just iced a 4-tiered 12/10/8/6 wedding cake using this method in UNDER an hour!! I’m slow and pokey at icing cakes, I can easily spend more than an hour icing a small layer alone. THANK YOU!!

@theajo, what type of frosting did you use? I will love to use this technique on my next cake order.

Your technique is fab. I will try it will buttercream made from butter – I hope it works.
Transfats are really bad for you, and the only brand of shortening available in the UK is transfat free due to the serious health risks associated with it. Shortening is not really used over here anyway, we just like butter I suppose. But thanks for sharing your recipe. i would have loved to make white buttercream.

This is FABULOUS! I was just checking out one of my absolute favorite cake artists Chocolate Moose on Flickr. Her edges are perfect and I was wondering how she does it! This is a great tip. I have a bride wanting very sharp square corners for a marine themed wedding cake! I am so glad I came across this! THANKS A MILLION!

I can’t help but say this, the top edge on the last picture looks photoshopped to me.Kind of zigzagged. I hope its not because it seems like a great method.

doramoreno62 – I agree that pic does look photoshopped. I use photoshop daily. Zig zag is there. Maybe it pixelated or something. But if you look at the pic where he is pulling the top paper off – it is noticeably smooth. I am getting ready to try it after a cake tasting. So I will let you know

The TattooedCakeLady, did you try this method? I’m very curious to know how it turned out.
