What if I told you that one of the most tender, deeply chocolatey cakes you will ever bake requires no eggs, no butter, no milk, and not even a mixing bowl? That is exactly what a Wacky Cake delivers.
Use an ungreased 20x20cm (8x8-inch) glass or ceramic dish for best texture. A 1:1 gluten-free flour blend can replace the all-purpose flour if needed. Apple cider vinegar works as a substitute for white vinegar, and sunflower oil or canola oil can replace vegetable oil. The butter must be at room temperature before you start whipping the frosting.
