Polish Blueberry Buns Delight (Print Version)

# Ingredients:

→ Dough

01 - 4 cups all-purpose flour
02 - 1 cup warm milk
03 - ½ cup unsalted butter, melted
04 - ¼ cup sugar
05 - 2 ¼ tsp instant yeast
06 - 1 tsp vanilla extract
07 - 1 egg
08 - ½ tsp salt

→ Blueberry Filling

09 - 2 cups fresh blueberries
10 - ¼ cup sugar
11 - 1 tbsp cornstarch

→ Streusel Topping

12 - ¼ cup all-purpose flour
13 - 2 tbsp sugar
14 - 2 tbsp cold butter, cubed

→ Optional Additions

15 - Lemon zest for extra freshness
16 - Cinnamon in the streusel
17 - Powdered sugar glaze for added sweetness
18 - Almond flakes for a nutty crunch

# Instructions:

01 - In a bowl, whisk together warm milk, sugar, and yeast. Let sit for 5-10 minutes until foamy. Add melted butter, egg, vanilla, and salt. Gradually mix in the flour until a dough forms. Knead for about 8-10 minutes until smooth and elastic. Cover the dough with a towel and let it rise in a warm place for 1-1.5 hours, until doubled in size.
02 - In a bowl, toss blueberries with sugar and cornstarch. Set aside.
03 - Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper. Punch down the dough and divide it into 10-12 equal portions. Flatten each piece into a small disc, place a spoonful of blueberry filling in the center, and seal the edges tightly. Place buns seam-side down on the baking sheet.
04 - In a bowl, mix flour, sugar, and butter with your fingers until crumbly. Brush the buns with a little milk or egg wash and sprinkle with streusel. Bake for 18-22 minutes until golden brown. Let cool slightly before serving.

# Notes:

01 - Use warm (not hot) milk to activate the yeast properly.
02 - Let the dough rise in a warm, draft-free space to ensure fluffiness.
03 - Coat the blueberries in cornstarch to avoid extra moisture in the dough.
04 - Avoid overfilling the buns to prevent bursting during baking.
