Bolo de Arroz is a traditional Portuguese rice cake that is enjoyed as a sweet treat or for breakfast. The cake is made with a combination of rice flour, sugar, eggs, butter, and a hint of lemon zest. The batter is then poured into individual muffin tins and baked until golden brown and slightly crispy on the outside. Bolo de Arroz has a soft and fluffy texture with a subtle sweetness. It is often enjoyed with a cup of coffee or tea and is a popular snack in Portugal.
