Attach the dough hook to your kitchen mixer.
Add the milk, coconut oil, coconut sugar and aquafaba to the bowl of your mixer and mix together.
150 ml dairy free milk, 50 g coconut oil, 30 g coconut sugar, 1 tbsp aquafaba
In a separate bowl, mix together the flour, baking powder and yeast (*see note). Add this to the bowl of your mixer a little at a time, whilst it is on a low speed.
250 g plain flour, 2 tsp baking powder, 1 1/4 tsp dried yeast
Once all of the flour mixture is in the mixing bowl, leave it for 8 minutes to mix on a low speed. You may need to scrape down the bowl once or twice in that time to combine.
After 8 minutes, increase the speed to high for 2 minutes.
Put the dough in a lightly oiled bowl and leave it in a warm place, covered with a tea towel (but not touching the dough), to prove (rise) for 1 1/2 hours.
Cut out squares of parchment paper a little bigger than you want your doughnut holes to be and spread them out on a tray with a small space between each of them.
Once the dough has finished proving divide it into 20 and roll each section lightly between the palms of your hands to smooth it into a small ball (approx the size of a walnut in its shell).
Place each doughnut hole onto its own square of parchment paper. The parchment stops them sticking to anything so they're easier to pick up when you're ready to cook them.
Prove the doughnut holes in a warm place, covered with a tea towel for another 45 minutes.
