For frosting, you may choose a store-bought vegan option or prepare your own. Consider enhancing the presentation with toppings such as sprinkles, chopped nuts, seeds, or fresh fruit. If substituting olive oil, opt for another minimally processed oil like avocado or coconut oil, though any plant-based oil will suffice. Brown sugar may be replaced with coconut sugar for a comparable texture and sweetness. For a gluten-free version, use an all-purpose gluten-free flour blend; if it lacks xanthan gum, include a small pinch during the mixing of dry ingredients.
