Prepare the dough:Mix all-purpose flour, glutinous rice flour, sugar, salt, and yeast in a large bowl.Gradually add warm water and vegetable oil. Knead until a smooth, elastic dough forms.Cover and let it rise for 1 hour or until it doubles in size.Prepare the filling:Mix brown sugar, chopped nuts, and cinnamon in a small bowl.Shape the pancakes:Divide the dough into 4 equal portions.Flatten each portion into a disc, place 1–2 tbsp of filling in the center, and pinch the edges to seal.Gently flatten the filled dough into a thick pancake shape.Cook the pancakes:Heat a non-stick pan over medium heat and add a small amount of oil.Place the pancakes in the pan and cook for 2–3 minutes on each side until golden brown.Press slightly with a spatula to help the filling spread and caramelize.Serve warm:Best enjoyed fresh and warm, straight from the pan.
