In a mixing bowl, combine the flour, sugar, yeast, and salt.

In a separate bowl, whisk together the warm milk, eggs, and melted butter.

Gradually add the wet ingredients to the dry ingredients and mix until a dough forms.

Transfer the dough to a floured surface and knead for about 5–7 minutes until smooth and elastic.

Shape the dough into a ball and place it in a greased bowl. Cover with a kitchen towel and let it rise in a warm place for about 30 minutes or until doubled in size.

Once risen, punch down the dough and transfer it to a floured surface.

Roll it out into a rectangle, approximately 1/4-inch thick.

Spread the brownie batter evenly over the dough, leaving a small border around the edges.

Sprinkle chocolate chunks or nuts for an added crunch if desired.

Starting from one long edge, carefully roll the dough tightly into a log.

Slice the log into 12 equal pieces.

Place the rolls in a greased baking dish, cover them again, and let them rise for another 20 minutes.

Preheat your oven to 350°F (175°C). Bake for 20-25 minutes or until golden brown.

Once baked, let the rolls cool for a few minutes before drizzling with optional chocolate icing or serving with vanilla ice cream.
