Tips For Making Apple Oat Muffins

  • Use any kind of apple you like. I prefer Granny Smith or Honeycrisp. Use your favorite kind.
  • You can grate the apple with the skin on! I promise you won’t even notice any bits of skin in the muffins. 
  • The apple will start to brown after sitting out, so it might be better if you do it right before it is needed. 
  • Any pie spice will work – pumpkin pie spice and apple pie spice are the most accessible.
  • If you don’t have buttermilk, you can make your own by combining 1 cup milk with the juice of 1 lemon. Let the mixture sit for 5 minutes, then pour into the bowl.
  • You can omit the cinnamon from the glaze if preferred.
  • If you don’t want to make & use a glaze with these muffins, that’s okay!
  • These muffins will stay fresh for 3-4 days when stored in an airtight container.

Can You Freeze Apple Muffins?

Yes! Muffins are the perfect food to freeze for easy breakfasts or snacks!

Once the muffins have baked and cooled, arrange them in a single layer on a dish or baking sheet. Pop the sheet in the freezer for 30 minutes (this is flash freezing!) or until the muffins are frozen solid.

Place frozen muffins in airtight freezer bags. Gently place the freezer bag into another freezer bag.

Repeat until all of the muffins are packed. Now, label and freeze the bags for up to three months.

How to Re-Heat Frozen Muffins

Thaw at room temperature for several hours. Then, enjoy or gently heat up int he oven at 350 degrees for just a few minutes!

For a quick thaw and eat method, place a single muffin in one paper towels and place in the microwave for a few seconds. That’s one of those lazy morning hacks! :)
