These blueberry oat muffins are a classic recipe here on THM that have been revamped with updated pictures and instructions. I’m thankful for the frozen blueberries (we have a Costco-sized bag of frozen organic wild blueberries at all times) that make these blueberry oatmeal muffins possible.

So if you’re wanting to enjoy a moist and decadent blueberry oatmeal muffin year round, I’ve got you covered with this delightful recipe!

Why Make This Recipe:

  • Gluten-Free – this recipe is technically gluten-free though you can easily substitute whole wheat flour if you are not gluten-free.
  • Bakery-Style – these blueberry oat muffins have a bakery-style flavor while still being low in fat and sugar.
  • Pecan Streusel – need I say more? This pecan streusel is so delicious and really amps up the flavor of these muffins!

Ingredients Needed

  • Blueberries – you can use fresh or frozen blueberries.
  • Gluten-free flour – whole wheat flour works as well! You could try all-purpose flour I just haven’t tried it myself!
  • Rolled oats – grab gluten-free oats if needed. Oats are a fantastic source of fiber.
  • Coconut palm sugar – brown sugar works as well.
  • Unsweetened almond milk – any dairy-free milk will work (oat milk is also great!)
  • Coconut oil -melted.
  • Large Egg
  • Applesauce -I add applesauce to help cut down on the oil while still maintaining the moistness these muffins require. You can replace with additional coconut oil if you don’t have applesauce.
  • Vanilla extract
  • Baking powder
  • Cinnamon – Just a half teaspoon ground cinnamon but feel free to use more if desired!
  • Sea salt

How to Make Pecan Streusel

Want to know what takes these blueberry oatmeal muffins to the next level? This pecan streusel! It adds a nice texture and crunch to these blueberry oat muffins. It’s optional but highly recommended. Here’s what you need:

  • Pecans -chopped up finely
  • Coconut oil – butter works too!
  • Coconut palm sugar – brown sugar works as well

Combine the finely chopped pecans and coconut palm sugar. Add the coconut oil to the mixture and use your hands to mix in the oil. Easy peasy!

How to Make Blueberry Oatmeal Muffins

STEP 1: MAKE STREUSEL

Make the streusel first by following the above instructions.

STEP 2: MIX DRY INGREDIENTS

Whisk together the dry ingredients: flour, rolled oats, coconut palm sugar, baking powder, salt and cinnamon in a large bowl.

STEP 3: MIX WET INGREDIENTS + COMBINE

In a separate medium bowl, combine the wet ingredients: the coconut oil, almond milk, egg, applesauce and vanilla extract. Add the wet mixture to the dry ingredients and stir until combined. Fold in the blueberries.

STEP 4: BAKE MUFFINS

Place muffin cups in muffin pan. Fill a prepped muffin tin 3/4 full with the batter. Top the batter with the pecan streusel (if desired) and bake for 20 minutes at 400ºF.

Easy Swaps & Substitutions

I think these blueberry muffins taste delicious as is but there are a couple of swaps & substitutions you can make if needed.

  • Swap the berries – you can easily swap in blackberries or raspberries in place of blueberries. Fresh or frozen will both work.
  • Change the milk – I like unsweetened almond milk in these blueberry oatmeal muffins but any plant-based milk will do. Dairy milk will likely also work but note that I haven’t tested it myself.
  • Substitute the flour – I have tested these with both gluten-free flour and whole wheat flour. I have not tested them with all-purpose white flour but they will likely work.
  • Add some zest – add the zest of a lemon to your batter for a blueberry lemon oat muffin!

*Note: I have not tried making these muffins without an egg. You’re welcome to try substituting with a flax egg but I have not tested it so be warned!

Storage Instructions

Let the muffins cool completely before placing them in an airtight container. Store at room temperature for up to three days. These muffins refrigerate and freeze well if you need to store for longer. 

To freeze: Store in a single layer in a large ziploc bag (you may need to use more than one bag). Remove from freezer a few hours before eating to bring to room temperature.
