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: https://sugarandsparrow.com/smooth-bu...
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.
