anyone have a good recipe for a mini donut maker?
I would think any recipe would work but start out with just a few. Cake batter would probably work too.
Do I have to separate the donut dough?
I don’t understand the question.
For fillings, you could try custard or caramel and (this ones off the top of my head) if they’re big enough, some pie filling (not too much or it’ll get too heavy). You could also dust the top with cinnamon and powdered sugar. If you’re interested in doing more of a test recipe you can try adding blueberries (like you would to a muffin, coated in a little flour) but be prepared for a purple donut.
