Turn your donut maker on/plug it in or preheat your oven to 350f. Spray your mini donut pan with spray oil.
In a small bowl, combine the milk and apple cider vinegar and set aside for 10 minutes or so, as this creates a "buttermilk" like substitute and really adds to the texture of these donuts!
. In a large bowl, combine the remaining ingredients. Mix well, then add in the milk mixture, mixing until just combined.
Pour the batter into the donut maker or greased pan and cook until the tops are firm to touch - keep in mind the time will vary depending on the donut maker you're using or the pan you're baking with. I haven't baked these in the oven, so i'd check them around 10 minutes.
Note: if you're using a standard donut pan, you may need to bake them longer. Just keep an eye on them and try not to open the oven too many times!
Once they're done, remove them from the oven and allow them to cool completely.
You can frost them or decorate them however you'd like! I melted some white chocolate and separated it between two bowls. I added some all-natural red food coloring to one bowl to create the pretty pink color. I dipped the donuts in the melted chocolate and placed them on a wire rack covered with a piece of parchment paper, then popped them in the fridge to firm up.
Keep in mind if you use chocolate, the donuts will need to be stored in the fridge as the chocolate will melt if left at room-temp. You can also use a regular glaze, etc.!
