Instructions
Preheat the oven to 180°C / 360°F (160°C fan), and lightly grease a mini doughnut pan. Place the butter and sugar into a medium bowl and beat well with a hand-held electric mixer until light and fluffy. You can use a stand mixer if you like, although due to the smaller amount of batter involved in these little doughnuts, it can be easier to use a hand-held mixer.
Mix in the egg and vanilla extract, then whisk thoroughly until well combined. The batter will curdle, but that’s okay. Sift the flour, baking powder, bicarbonate of soda and salt into the bowl with the batter, and then add the freshly grated nutmeg. Mix together until fully incorporated.
Pour the buttermilk into the batter and stir until it reaches a smooth consistency. Be careful not to over-mix, as you don’t want the doughnuts to be tough.
Spoon the batter into six smaller bowls, trying to be as equal as possible – there’s no need to weigh the batter, I like to just eyeball it. Add a different food colouring to each bowl, mixing well to ensure that each colour is even.
Either pipe or spoon the batters into the doughnut tin in a rainbow pattern, ensuring that each hole is about half full. Knock the doughnut pan on the table a few times to help get rid of any air bubbles, and then place in the preheated oven for about 10 minutes until a skewer or toothpick inserted into one of doughnuts comes out clean. Immediately transfer the doughnuts from the pan to a wire rack to let them cool.

Notes
To keep the doughnuts fresh, store them in an airtight container, and they’ll last for 3-4 days. For longer storage, freeze them for up to 3 months, then thaw at room temperature when ready to enjoy. Recipe inspired by Cupcake Jemma.
