If it hasn't reached a very fine, almost powdery texture, continue pulsing your blender. Note: Do not substitute powdered (icing) sugar for caster sugar. Powdered sugar is mixed with corn starch, which can affect the texture of your finished cakes.

If by "normal" flour you mean all-purpose or plain flour, then it is possible but you'd need to add raising agents to the flour for it to work properly.
