Here's how to make blueberry cream cheese muffins using rice flour and melted butter. Prepare muffin tins with parchment paper, then mix eggs, brown sugar, melted butter, and milk in that order, adding rice flour and baking powder to make the batter. Pipe the batter into the tins, top with cream cheese and blueberry jam, and bake in a preheated oven at 180°C for 16-18 minutes. You'll have moist, fluffy, and filling muffins.
