Mix flour, yeast, sugar, and milk in a large bowl. Knead until smooth, cover and let rise in a warm area for about 1 hour.

Preheat the oven to 350°F (175°C) and grease a bundt pan with butter.

Punch down the dough, divide into small pieces, and roll each into a ball. Coat each ball in melted butter, sugar, and cinnamon mixture.

Layer the coated dough balls in the bundt pan, scattering blueberries between layers until all used up.

Bake for about 30-40 minutes until puffed and golden brown. Check with a toothpick to ensure it's cooked through.

Let the monkey bread cool for 10 minutes before inverting onto a serving plate.
