Sienna Bakery premium stuffed muffins boldly enhance classic muffin flavor with delicious fillings. No aspect of these muffins has been overlooked. We start with a rich batter including real butter, sweet cinnamon and sugar, top them with a decorative streusel topping, and only use the highest quality ingredients. Then we pair them with a toasty, thick Caramel filling which enhances the already delicious flavors.
