Marble Buttercream Cake Tutorial feat. the JOANN Stir Collection

Learn how to create a beautiful marble buttercream cake with gold painted details. This tutorial is sponsored by JOANN's Stir line of baking and cake decorating tools and I couldn't help but create this cake inspired by the gold/marble color palette of the tools. Get the full tutorial here: sugarandsparro...
Tools & Materials:
A 6-inch cake that’s been crumb coated and chilled
Cake turntable: www.joann.com/...
1.5 batches of vanilla buttercream: sugarandsparro...
Black food color gel: www.joann.com/...
Bowls and spoons for color mixing
Baker’s twine
Parchment paper
Scissors
Scotch tape
Icing spatula set: www.joann.com/...
Icing smoother
Fondant smoother: www.joann.com/...
Small food-grade paint brush: www.joann.com/...
Gold luster dust: www.joann.com/...
Clear extract (lemon or vanilla) or vodka
Step 1: Frost a smooth buttercream finish on the chilled, crumb coated cake. Place the frosted cake into the refrigerator for at least 30 minutes. Here's a great tutorial for creating a smooth finish: sugarandsparro...
Step 2: Mix the marble buttercream color palette. Divide the remaining buttercream into three small bowls. Add 2 drops of black food color gel into the first bowl and gently mix it with your spatula until it’s about half mixed. You’ll want a dark grey color with some streaks of white/lighter grey in there. Scoop out about 1 teaspoon of this dark grey marble color and mix it into the second bowl. Repeat the process of mixing until you have a light grey color with streaks of white mixed in. Keep the last bowl uncolored.
Step 3: Trim a piece of parchment paper based on the height and circumference of the cake. Place swatches of the different buttercream colors onto the parchment paper, covering the length of the parchment but varying in height.
Step 4: Wrap the marble parchment around the chilled, frosted cake and smooth it down with an icing smoother to adhere it. Place it back into the refrigerator for at least 30 minutes.
Step 5: Gently peel away the parchment paper and paint the raw edge with gold edible paint.

I found you video yesterday and used it for my sons 18th Birthday cake. It turned out pretty good for a first attempt. Thank you for the inspiration.

[@laurazeller2014]

Beautiful, Whitney! Thank you!

[@rebekahgrace-]

[@moduqueRN]

Beautiful cake! 🎉😊

[@Renesmeedevil]

that's amazing! do you think it will work on swiss meringue buttercream too?

[@ntombi105]

This is so pretty😊😊😊

[@Kue_Eva_Cake]

Oh banyak juga perlengkapannya.... Mantap

[@shawnaellis9059]

Such a beautiful effect! Is there a way to extend the marbling ABOVE the top of the cake? I'm wanting to do something that looks like a stone flower pot with succulents and cacti inside. So I need the marbling to be higher on the outside. Suggestions?

[@arishachoudhury_]

ik this is really late and kinda useless but you might want to sandwich it between 2 layers and then cool it to have it be even, then when youre done refrigerate the cake to firm up the buttercream some more? or maybe swap buttercreamfor something like chocolate and try something like a chocolate cage?

[@donnaroff4072]

Could you use vanilla extract to mix with the lustre dust?

[@christiecorcino4172]

Will it work in whipped cream frosting?

[@hae1123]

Hi! Is marbling how-to in your cookbook? Can’t wait for your cookbook to arrive!

[@SugarandSparrow]

I’m so excited for you to have my cookbook!! 🥳 thanks so much! There isn’t a marbling tutorial in there but there are lots of other decorating styles - stripes, ombré, textured buttercream, Lambeth piping, extra smooth buttercream, and more!

[@evelinyusti6348]

Wooow 😍😍😍

[@cassiericard1]

Why couldn't you just use this same technique directly on the cake? What does the extra step add?

[@SugarandSparrow]

This technique is easier imo because the acetate keeps marble texture in place without mixing the colors together too much. There are other techniques out there for creating a marble finish directly on the cake if you want to try them though!
