Place the coconut milk in a small saucepan and heat over medium heat until just simmering. Turn the heat off and stir in the yeast and apple cider vinegar. Set aside.
In a large mixing bowl, add the cassava flour, xylitol, guar gum. Baking powder and salt. Stir with a whisk to mix.
Next add the egg and egg white, melted coconut oil and vanilla essence. Stir with a spoon.
Fit your electric beater with the dough hook, place it in the mixing bowl and turn it on. Slowly pour in the milk mixture while beating.
Beat until your dough comes together in a ball.
Turn the dough onto a sheet of baking paper. Cover with another sheet of baking paper and roll it out to approximately 2 cm thick.
Flour a doughnut cutter and cut the dough into doughnut shapes. Gather the remaining dough, re-roll and cut until you have used all the dough. Alternatively, break pieces of the dough off and roll into doughnut balls.
Place the doughnuts on a baking tray lined with baking paper and place them in your (turned-off) oven with a bowl of boiling water alongside them to rise.
While the doughnuts are rising make the glaze or the dust coat.
For the Glaze I used the cupcake icing recipe from my book, Mila’s Meals: The Beginning and The Basics with a slight variation (coconut butter instead of coconut oil). In a small saucepan melt the coconut butter over low heat while stirring. Once melted, add the xylitol, vanilla essence and coconut milk. Turn the heat off and set aside until the donuts are cooked and cooled. For the dust coat: Mix the xylitol with the cinnamon and pour onto a plate. Set aside until the donuts are cooked.
After the doughnuts have risen for half an hour, heat the additional coconut oil in a heavy-based pan. Test the oil to see if it is hot enough by dropping a small piece of doughnut dough into it. If the oil immediately starts bubbling around the doughnut – it is ready to use.
One by one, place the doughnuts into the hot oil with a slotted spoon. Cook for 30 seconds – 1 minute on each side, turning frequently until golden brown all over. Remove from the oil with a slotted spoon, and place on a wire wrack to cool or if you are dusting them, onto the plate with the xylitol and cinnamon – roll them around to coat them in the dust.
If you are using the glaze, wait for the doughnuts to cool, then dip them into the glaze.
Notes
*I find the doughnut balls have a better texture than the round-shaped doughnuts.
