Rainbow layer cake

[nowa]

Ok who has made one of these? Can you recommend your recipe? I'm good at baking but I'm just okay at frosting so this really intimidates me because of all the layers. Share any lessons or tips!

I made one for DD years ago, she loved it. White cake can be tricky and takes like a dozen egg whites so wasn't willing to make it from scratch (I was also 9m pg;)
I used a white cake mix (double batch) and after I mixed I divided evenly into 5 bowls.
Gel food coloring is the best, you only need a tiny bit. I used a toothpick to add the colors.
I used 9" pans, make sure the sides of the pans are straight up and down instead of fanned out.
After each layer baked and cooled, I trimmed the tops flat.
I used a classic butter cream icing recipe, iced each layer. Added a crumb coat and refrigerate overnight covered in plastic wrap.
Finish final icing layer the next day. I did not color the icing.

Tips
*I always do a crumb coat
*line each pan with a parchment paper circle (with cooking spray), comes out flawless
*buy a cardboard cake circle and build the cake on it (easy to move onto a stand)
*tear 3 strips of parchment paper and put them under the bottom layer before icing, pull away after finished.

My Mom has made this one and it turned put awesome! It's impressive looking because it's very tall. It's easy to make, and uses Cool Whip for frosting, but you could also use just regular frosting if you wanted to. The only thing she found was the colours were not quite as vibrant as in the picture, so she said next time she would try adding a bit of food colouring to each. She said the Jello doesn't add much flavour, it's more for the colour.

Ha, I made one but I don't remember! I always use a basic buttercream recipe butter, sugar, vanilla & a tad bit of cream.

I did 6 layers and use wilton gel food coloring.

I'll see if I can find the recipe or blog I used.

Oh, Jelly that is funny, now. I'm sure it wasn't then!

I think this is the cake recipe I used: www.whisk-kid.com/2009/08/say-it-with-cake.html

I made it and used boxed white cake mix with gel food coloring and canned icing. I did 3 cakes with each layer cut in half (it helps if you freeze the cakes before cutting, then use a serated knife). My main tip is to use some sort of support! Even with trimming, my cakes weren't entirely flat, and as I got to the top when I was stacking/icing it, the center was a bit higher than the edges, and the top layer ended up breaking apart and sliding off. I ended up cutting some wooden skewers and sticking it through the remaining layers and that worked well. It was REALLY hot out when I was icing mine though.

The thick large plastic boba or pearl tea straws work great for skewering cakes as you can easily trim them once they inserted and actually hold cake in place better than wooden skewers. You can get them at asian markets or if you have a local place that sells boba tea I'm sure they would give you some. You would need 3 to 6 depending on the size of your cake.
You've gotten some great advice. Youtube also has some pretty great cake decorating/assembling videos.

I did this for DD1's 3rd bday and it turned out soooo neat! I can't remember exactly what I did compared to what she did at the link below. I know I didn't make anything diet, and I think I just made the cake mix rather than using soda. I doubled it, as recommended, and I made 3 layers. Definitely use the gel colors. I did the Cool Whip/pudding frosting which actually tasted great. I put rainbow-colored sprinkle mix all over the top and some tall colorful candles.

If I knew how to PIP I would show you a picture.

PS Now that I'm thinking about it, I may have actually tripled the recipe and then made the extra into cupcakes. I think I was afraid of running short of batter and  I wanted three layers.
