How to Store Leftover Muffins

Store leftover muffins in an airtight container for up to 4 days. These muffins can also be frozen. Store in a freezer bag and microwave for 15-20 seconds to thaw when ready to enjoy!

Tips for Perfect Oatmeal Blueberry Muffins

  • Once the muffins are done let cool for 1 minute in the pan, then transfer to a wire rack to finish cooling. This helps prevent soggy muffins.
  • Do NOT over mix the batter. When mixing in the dry ingredients, mix until just combined. It’s ok if there are a few streaks of flour. This helps the muffins rise and stay fluffy.
  • No buttermilk? No problem! Try these vegan blueberry muffins instead, no buttermilk required!
