- Preheat Your Mini Doughnut Maker: Follow the manufacturer’s instructions for your mini doughnut maker and preheat it.
- Prepare the Batter: In a mixing bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon (if using).
- Combine Wet Ingredients: In another bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract.
- Mix Wet and Dry Ingredients: Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix; the batter should be slightly lumpy.
- Fill the Doughnut Maker: Lightly grease the doughnut maker with non-stick cooking spray. Spoon or pipe the batter into the doughnut molds, filling each about halfway.
- Cook the Mini Doughnuts: Close the doughnut maker and cook according to the manufacturer’s instructions, usually for 3-5 minutes or until the doughnuts are golden brown.
- Prepare the Topping: In a shallow bowl, mix together the powdered sugar and ground cinnamon (if using). In another bowl, melt the butter.
- Coat the Doughnuts: Once the mini doughnuts are done, carefully remove them from the doughnut maker. Dip each doughnut into the melted butter, then roll in the cinnamon-sugar mixture until coated.
- Serve: Place the coated mini doughnuts on a serving plate. They are best served warm.
Enjoy these delightful mini doughnuts as a tasty treat for breakfast or as a sweet snack. Feel free to get creative with additional toppings or glazes if you like!
