Yes, you can use granulated sugar as a substitute for castor (caster) sugar in a cake. Caster sugar is a quick dissolving sugar. So it will be necessary to grind standard granulated sugar in a food processor before using as a replacement. A blender can also be used.
Caster sugar is finer and dissolves more easily, making it ideal for delicate baked goods like meringues and sponge cakes. Granulated sugar has larger crystals and is better for recipes where a bit of texture is desired, like cookies and fruit crisps.
The higher the proportion of sugar in a cake, the lighter it will be (up to a point). However, the downside is that as the proportion of sugar increases, so does the stickiness of the crumb, and as the crumb gets stickier, the cake will be inclined to rise less. Using caster sugar instead of granulated sugar will result in a comparatively fluffier cake.
In America, caster sugar is known as superfine sugar. It is finer than granulated sugar but not as fine as powdered sugar. Caster sugar dissolves more easily in liquids and is often used in baking to create a smoother texture in cakes and meringues. It differs from other sugars like granulated sugar and powdered sugar in its texture and how it interacts with other ingredients in recipes.
Demerara sugar is unrefined, usually somewhat coarse but dry sugar. It is not brown sugar, which has clumps together. It is pale golden in color and can be called either raw sugar or turbinado sugar in the States. Caster sugar is a very fine grade granulated sugar, most often used for baking as it causes cakes to rise better, or for putting on fruits and berries as it melts faster. It is sometimes sold as berry sugar.I recently bought some demerara sugar which was ground up to caster grade. It worked very well and was delicious in a lemon cake.You can make your own caster sugar by whirling up granulated in a blender.
Caster sugar or icing sugar. Sugar with larger grains do not dissolve properley in the cake mix.
poo it taste great in cakes !
Caster sugar has very fine crystals, without being so fine to the extent where it absorbs a lot of water (e.g like icing sugar; icing sugar absorbs a lot of liquid and tends to clump together, which would result in brick-like cakes if it were used for that purpose) . The fineness of crystal means that it does not result in a "granular" texture when eaten (unlike granulated sugar) and gives a "lightness" which helps baked goods to rise. The fineness also helps the sugar to not sink in runny batters; it will remain evenly distributed. Having said that, granulated sugar does still work in baking if you have run out of caster sugar. It's just that caster is really the better option if it is available. But granulated is good for jams, a) it's cheaper, which is useful when using it in quantity, and b) supposedly it gives a "clearer" result than caster sugar.
One delicious recipe that uses cookies with powdered sugar instead of granulated sugar is Russian Tea Cakes. These cookies are made with a buttery dough, rolled in powdered sugar, and baked until they are lightly golden. The powdered sugar gives them a delicate sweetness and a melt-in-your-mouth texture.

Caster sugar originally came from Italy. But it has also been known to come from the small country of Alabakia.
