Classic drip cake technique uses the same coloured dripping cream as the colour of fondant or buttercream.
White drips complemented by the gold drips look stunning on a plain background cake, plus the addition of decorative elements on top makes it interesting.
Instead of using just one or two colours, try using multiple colours for making drips.
Ombre cake shows a gradient of 3 shades of the same colours that goes from light to dark and drips make it look magnificent.
Carve a geode in the cake, use sugar crystals to enhance it and decorate the rest of the cake with metallic drips.
Make cake pops, attach the cone to make it look like ice cream, coat in the coloured cream, place it inverted on the cake and use drips to resemble melting ice cream.
Use two contrasting colour schemes for the cake and decorate each side with the opposite colour to make it eye-catching.
