Make simple, bright, and moist baked donut holes using a gluten-free flour blend, featuring strong lemon flavor and poppy seeds, finished with a simple glaze.
Preheat your oven to 350°F (175°C). Grease a 12-cup mini muffin pan or a specialized donut hole pan well.
In a large bowl, whisk together the gluten-free flour blend, granulated sugar, baking powder, salt, and poppy seeds.
In a separate medium bowl, whisk the milk, melted butter, egg, vanilla extract, lemon zest, and 2 tablespoons of lemon juice until combined.
Pour the wet ingredients into the dry ingredients. Mix gently until just combined. Do not overmix; a few small lumps are acceptable. The batter will be thick.
Spoon or scoop the batter evenly into the prepared mini muffin cups, filling each about two-thirds full.
Bake for 12 to 15 minutes, or until a toothpick inserted into the center comes out clean.
Let the donut holes cool in the pan for 5 minutes before carefully transferring them to a wire rack to cool completely.
While the donut holes cool, prepare the glaze. Whisk the powdered sugar and 2 tablespoons of lemon juice together until smooth. Add more lemon juice, a few drops at a time, if the glaze is too thick.
Dip the top of each cooled donut hole into the glaze, or drizzle the glaze over them. Let the glaze set before serving.
Notes
For the best texture in gluten-free baking, measure your flour by weight or use the spoon-and-level method.
If your batter seems too dry, add one extra teaspoon of milk. Gluten-free batters often hold less moisture than traditional batters.
You can use a small cookie scoop to portion the batter consistently into the pan.
