01 - Preheat the oven to 350°F (175°C). Grease a mini donut pan thoroughly to prevent sticking.
02 - In a large bowl, whisk together sweet rice flour, ground black sesame seeds, granulated sugar, baking powder, and salt until evenly distributed.
03 - In a separate bowl, beat eggs until uniform. Add milk, melted butter, and vanilla extract. Whisk until fully combined and smooth.
04 - Pour the wet ingredients into the dry mixture. Stir gently until a thick, smooth batter forms without overmixing.
05 - Spoon or pipe the batter into the prepared donut pan, filling each cavity approximately 3/4 full to allow for rising.
06 - Bake for 15–18 minutes, or until donuts spring back when lightly pressed and a toothpick inserted comes out clean.
07 - Let donuts rest in the pan for 5 minutes to set, then carefully transfer to a wire rack to cool completely.
08 - Whisk powdered sugar with 1 tbsp milk and black sesame paste until smooth. Adjust consistency with additional milk if needed for proper dipping texture.
09 - Dip the tops of cooled donuts into the glaze, allowing excess to drip off. Sprinkle with additional black sesame seeds if desired. Let glaze set before serving.
