Baked Rainbow Doughnuts

Preheat your oven to 180ºc (160ºc fan), gas mark 4. Combine the dry ingredients together in a bowl and then gradually add the wet ingredients (except the dyes) until just combined. 

Divide the batter equally into 6 bowls and colour with each of the food colourings.

Using a teaspoon (or piping bag), place the coloured mixtures in small amounts into each cavity of the doughnut pan, until 3/4 full. Swirl a little to acheive a marbled effect, or leave the colours in blocks.

Bake for 15 minutes or until the doughnuts have risen. Remove from the oven and allow to cool in the tin for a few minutes before removing to completely cool on a rack. 

To make the icing

Combine the icing sugar and lemon juice in a bowl. Mix these together until a runny icing has formed. If it's too thick, add more lemon juice, a teaspoon at a time. If it's too runny, add a tea spoon of icing sugar at a time to thicken it. 

Wait until the doughnuts have completely cooled before decorating them. Once iced, top with sprinkles, or however you like!
