Gluten Free Charcoal Sponge Cake

When we discovered the reason for my daughters bloat and pain was caused by gluten… we had to get creative. My sweet Bria has a sweet tooth and loves cake, so I created this ‘volcanic’ dessert with activated charcoal to put a smile on her face! This is the recipe for the sponge cake… I have simply layered it with whipped cream and served it with vanilla ice cream. The shards are created using a basic tuile mix with charcoal added to it. Play around and have fun!
