Preheat the oven to 350F (180C). Line 2 baking sheets with parchment paper or use 2 non-stick baking sheets.
Make the bread dough. In a large bowl, use your hands or a fork to combine the yuca, baking powder, salt, and butter. Add the egg and mix again. Finally, add the cheese and mix until a dough starts forming.
Pour in the milk in multiple additions, mixing well after every addition until you get a smooth moist dough that’s not sticky nor dry. Pan De Yuca dough is supposed to be moist, almost glimmering but should never stick to your hands or bowl.
Form into buns and place them onto your prepared baking sheets. You can use a 1 tbsp measuring spoon as a guide, they're supposed to be small buns.
Bake for 10-15 minutes or until golden/pale on the outside and soft (they shouldn't brown or toughen up). Serve immediately. Pan De Yuca is supposed to be served hot/warm or the chewy texture will harden up.
