Prepare the Blueberry Puree:

• In a small saucepan, combine fresh blueberries and sugar. Cook over medium heat, stirring occasionally, until the blueberries break down and release their juice (about 5-7 minutes).

• Once cooked, add lemon zest and lemon juice. Stir to combine.

• Remove from heat and allow the puree to cool. Set aside.

Prepare the Dough:

• In a bowl, combine yeast and warm milk. Let sit for 5-10 minutes until the yeast activates and bubbles form.

• Add sugar, bread flour, and salt into a large mixing bowl. Stir to combine.

• Add the eggs, vanilla extract, and softened butter to the flour mixture. Mix until it forms a dough.

• Knead the dough on a floured surface for 8-10 minutes, until smooth and elastic.

• Place the dough in a greased bowl, cover with a damp cloth, and let rise in a warm place for about 1 hour, or until doubled in size.

Shape the Rolls:

• Preheat your oven to 180°C (350°F).

• After the dough has risen, punch it down and roll it out into a rectangle (about 30cm x 40cm).

• Spread the cooled blueberry puree evenly over the dough.

• Roll the dough tightly from one side, then cut it into 12 equal-sized rolls.

• Place the rolls on a greased baking tray, leaving some space between each roll. Cover and let them rise for another 30 minutes.

Bake the Rolls:

• Bake the rolls in the preheated oven for 20-25 minutes, or until golden brown and cooked through.

Prepare the Frosting:

• While the rolls are baking, prepare the frosting by beating the cream cheese and butter together until smooth.

• Gradually add powdered sugar, mixing until smooth and fluffy.

• Stir in 15g of the prepared blueberry puree for a light blueberry flavor.

Assemble:

• Once the rolls are done baking, let them cool slightly before spreading the blueberry frosting over the top.

• Serve warm and enjoy your delicious Blueberry Rolls!
