This idea is so so simple. The picture explains what needs to be done. Just one watermelon is required. I love decorating it with cascading berries like blueberries, raspberries, strawberries, blackberries and even boysenberries. I think the contrast in colour looks awesome. Edible flowers also look amazing scattered through the berry waterfall.
This will be the quickest, easiest and healthiest cake you'll ever make. Not to mention it is dairy free, gluten free, vegan friendly. So many wins.
Tip... Use a few toothpicks for some of the berries to hold the rest of the cascading berry fountain in place.
