For enhanced flavor, add a dash of vanilla extract to the wet ingredients. If using fresh blueberries, gently toss them with a tablespoon of flour before adding them to the batter to prevent them from sinking to the bottom. These muffins are delicious served warm with a drizzle of maple syrup and a dollop of dairy-free butter or coconut cream. Store leftover muffins in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. They can also be frozen for longer storage.
