Store the baked and cooled muffins in an airtight container in the fridge for up to 5 days. We recommend reheating for 15-30 seconds in the microwave. You can freeze the baked muffins for longer storage, up to 3 months.

Can I use Frozen Blueberries in Muffins

Yes, with most recipes that call for fresh fruit, you can substitute frozen fruit, and these muffins are no exception. If using frozen berries, there’s no need to thaw them. We recommend adding the frozen blueberries directly to the batter and folding them in very gently.

Yes, you sure can. Mashed banana can almost always be used as a substitute for applesauce in baked good recipes. So, if you don’t have applesauce on hand or you want to turn this recipe into a Banana Blueberry Oatmeal Muffins, then simply substitute 1 mashed banana (about a 1/2 cup) for the applesauce in this recipe.
