Creating Lemon Blueberry Donuts is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a donut pan with non-stick spray or butter.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt.
3. Combine Wet Ingredients: In another bowl, mix the milk, vegetable oil, eggs, lemon zest, and vanilla extract until well combined.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently until just combined; do not overmix.
5. Add Blueberries: Fold in the blueberries carefully to avoid breaking them.
6. Fill the Donut Pan: Spoon the batter into the prepared donut pan, filling each mold about ¾ full.
7. Bake: Place in the preheated oven and bake for 15-20 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let the donuts cool in the pan for about 5 minutes, then transfer them to a wire rack to cool completely.
9. Make the Glaze: In a small bowl, whisk together the powdered sugar and lemon juice until smooth.
10. Glaze the Donuts: Once the donuts are cool, dip the tops into the glaze or drizzle it over them for a beautiful finish.
