📋 Ingredients

Before starting this recipe, you'll want to verify that you have the following ingredients:

  • Old Fashioned Rolled Oats - You can use regular rolled oats also.
  • Almond Milk - Only about a ¼ cup. You can substitute with regular milk if you prefer.
  • Ripe Bananas - Overripe bananas that are soft with dark spots work best.
  • Fresh Blueberries - Fresh and ripe blueberries work best in this recipe. However, you can substitute with frozen blueberries if you wish.

🍽 Equipment and Supplies Needed

The following equipment and supplies are needed to make this recipe.

  • 12-Count Muffin Tin - Standard Size
  • Non-Stick Spray - Used to grease the muffin tin to prevent the muffins from sticking.
  • Food Processor - This is used to chop and combine all the ingredients together to form one consistency. If you don't have a food processor, you can use a blender. However, a food processor will work better.
  • Ice Cream Scoop or Large Spoon - Used to scoop the batter into the muffin tin.

🔪 Tips and Instructions

This recipe is easy to make if you know the right tips and tricks! Here are our tips for ensuring your Oatmeal Muffins come out perfectly.

💭 Tip - Getting the Right Batter Consistency

The batter for these muffins is really thick because of the small amount of milk used (¼ cup) and the thick nature of oats. In order to make the batter correctly, I recommend that you blend all the ingredients together in a food processor.

One of the greatest things about our oatmeal muffins is how easy they are to make ahead of time and store. As a result, they're perfect for breakfast meal-prepping!


If you're making these for the week or just want to store extras, we recommend you freeze them. Just follow these easy steps:

  • Allow the muffins to fully cool to room temperature.
  • Wrap the muffins (separately is best) tightly in plastic wrap or inside a zippered freezer bag.
  • Be sure to remove as much air as possible.
  • Place inside the freezer and store them for up to 1 month.

When you're ready to eat a muffin (or two), just follow these steps:

  • Remove it from the freezer.
  • Remove the plastic wrap or bag.
  • Place the frozen muffin on a paper towel or microwave safe plate.
  • Microwave on high for 30 seconds.
  • Check the muffin to make sure it's warm and fully defrosted. If not, microwave on high in additional 15 second increments until fully defrosted and warm.

The oatmeal consistency of these muffins make them a good candidate for reheating. You'll notice that the texture is almost identical as it was when they were fresh from the oven.
