In a large bowl, mix together the flour, cocoa powder, brown sugar, salt, and instant yeast until everything is evenly combined.

Make a well in the center and pour in the warm oat milk and vegetable oil. Stir until the dry ingredients are fully incorporated.

Knead the dough on a lightly floured surface for 7-10 minutes, until it becomes smooth, elastic, and stretches more than it tears. The dough will be sticky, but try not to add more than 1/4 cup of extra flour.

Place the dough in an oiled bowl, cover with plastic wrap or a damp towel, and let it rise in a warm spot for about 1 hour, or until it has doubled in size.

In a small bowl, mix together the brown sugar and cinnamon until well combined.

Melt the coconut oil and chop the chocolate or use mini chocolate chips.

Once the dough has risen, turn it out onto a lightly floured surface. Roll or stretch the dough into a rectangle, about 14 inches by 20 inches.

Brush the melted coconut oil evenly over the surface. Sprinkle the cinnamon-sugar mixture all over, making sure to cover the entire surface.

Scatter the chopped chocolate or mini chocolate chips evenly on top.

Starting from the long side, gently but tightly roll the dough up. Place the seam side down.

Using a sharp knife, slice the dough into 12 even rolls. Place them in a prepared baking dish, spaced evenly.

Cover the rolls with plastic wrap or a damp cloth, and let them rise again for about 30-45 minutes, until doubled in size.

Preheat your oven to 350°F while the rolls are rising.

Once the rolls have risen, remove the plastic wrap and bake for 22-27 minutes, or until the center of the rolls is firm and springs back when touched.

Remove from the oven and allow them to cool for 15-20 minutes.

While the rolls are cooling, prepare the glaze. In a saucepan over medium-low heat, melt the coconut oil with the oat milk and cocoa powder, stirring until smooth and steaming.

Add the powdered sugar and stir until the glaze is smooth. Bring the mixture to a simmer, stirring constantly, and cook for about 2 minutes.

Remove from heat and allow the glaze to cool slightly before pouring over the cooled rolls.

Pour the glaze over the cooled rolls. These rolls are best enjoyed the same day, while still warm and fresh!
