Follow these steps to create your Lemon Blueberry Swirl Buns perfectly:

1. Prepare the Dough: In a mixing bowl, combine flour, sugar, salt, and yeast. Whisk together until well mixed.
2. Mix Wet Ingredients: In another bowl, combine the warm milk, melted butter, and eggs. Mix in the lemon zest.
3. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients. Stir until a dough begins to form.
4. Knead the Dough: Transfer the dough to a floured surface. Knead for about 5-7 minutes until smooth and elastic.
5. First Rise: Place the dough in a greased bowl, cover it with a damp cloth, and allow it to rise in a warm place for about 1 hour or until doubled in size.
6. Prepare Filling: In a small bowl, combine the blueberries and lemon juice. Toss gently to incorporate.
7. Roll Out Dough: Once the dough has risen, punch it down and transfer it to a floured surface. Roll it out into a rectangle, about ¼ inch thick.
8. Add Filling: Spread the blueberry-lemon mixture evenly over the rolled-out dough.
9. Roll Into a Log: Starting from one edge, roll the dough tightly into a log.
10. Cut the Buns: Slice the log into equal pieces (about 1.5 inches thick), and place them in a greased baking dish.
11. Second Rise: Cover the rolled buns with plastic wrap or a kitchen towel and let them rise for another 30 minutes.
12. Preheat Oven: Preheat your oven to 350°F (175°C).
13. Bake the Buns: Bake the buns in the preheated oven for 25-30 minutes or until golden brown.
14. Prepare Glaze: In a small bowl, whisk together powdered sugar and a tablespoon of lemon juice until smooth.
15. Drizzle the Glaze: Once the buns are out of the oven, let them cool for a few minutes before drizzling with the glaze.
