Packed with juicy berries and a hint of vanilla, these muffins are easy to make and even easier to enjoy.

Why Choose Marionberries?
Marionberries are a type of blackberry but are more oblong and tend to be sweeter and juicier. These berries were named after Marion County, Oregon, where the berry was bred and tested in the mid-20th century. Oregon accounts for over 90% of the worldwide acreage of marionberries.
Marionberries, often called the “Cabernet of Blackberries,” are known for their complex, rich flavor. They are larger, juicier, and have a more intense flavor compared to regular blackberries. Perfect for baking, Marionberries add a burst of sweetness and tartness to your muffins.
