Muffins: The Any Season Snack or Breakfast
Summer may not seem like muffin-making season. I beg to differ. It’s always a great time to bake a batch of muffins, including, sunny, humid, 90-degree days in June.
Muffins are perfect for quick, easy, & nutritious breakfasts in a flash, packing into bag lunches (for camp, a sunny day at the beach, or a day hike), and grabbing for a quick snack or pre-workout gnosh.
Moreover, many muffins are quick and easy to make with items I already have on hand, for little expense (I come close to fainting when I spy $3.00 muffins in coffee shop cases–make that a double espresso, stat!).
For an exemplary version of easy, whole, grab & go anytime muffins, I offer my recipe for Vegan Peanut Butter Banana Oat Muffins.

Virtues of These Muffins
- Vegan (no egg, no dairy)
- Gluten-free
- Oil-free
- 100% oats
- Made in 1 bowl
- Made with pantry ingredients
- Low in sugar
- 149 calories each
Ingredients to Make the Muffins
The exact amounts of each ingredient are indicated in the recipe card at the end of the post. Toggle between US Customary (volume) and Metric (weights) for preferred measurement option.
Ripe bananas, with plenty of brown on the peels, are key to the success of the recipe. The starch in bananas breaks down into sugar as the bananas ripen, making them soft, squishy, and sweet.

In addition to bananas, you will need the following:
- Rolled oats (certified gluten-free, as needed)
- Nondairy milk (any variety you prefer)
- Coconut sugar (I have options for alternatives in the recipe card)
- Smooth natural peanut butter (or any nut or seed butter you prefer)
- Flaxseed meal
- Vanilla extract
- Baking powder
- Baking soda
- Cinnamon
- Salt
Step by Step Directions
Note that the complete directions are also in the recipe card below.
Step 1: Prep the Muffin Tin & Preheat the Oven
Preheat your oven oven to 325F (160C). These muffins bake at a lower temperature that many traditional muffins to ensure even baking in the absence of eggs and gluten. Line all 12 cups of a standard size muffin tin with paper or foil liners.
Step 2: Grind a Portion of the Oats.
Three cups of rolled oats are used in the recipe (all of the ingredient amounts are in the recipe card below). Since these are muffins, not baked oatmeal cups, begin by grinding 1 and 3/4 cups of the oats into a fine flour. You can use either a food processor or high speed blender for this quick task.
Step 3: Whisk the Wet Ingredients
Grab a big mixing bowl (you will only need one!) and whisk together all of the wet ingredients–the mashed bananas, nondairy milk, coconut sugar, peanut butter, flaxseed meal, and vanilla–until blended and smooth.

Step 4: Add the Dry Ingredients
Add the oat flour, remaining rolled oats, baking powder, baking soda, cinnamon, and salt. Stir until completely blended.
Step 5: Portion into Muffin Cups
Divide the batter equally between the prepared muffin cups. I like to sprinkle a few extra rolled oats on top, but it is entirely optional.

Step 6: Bake!
Bake the muffins in the preheated oven for 23 to 27 minutes until golden brown and risen. These muffins do not get peaks, but they will develop fluffy, golden tops.
Let the muffins cool in the muffin tin for 5 minutes and then remove and cool completely an a cooling rack.
These pretty muffins are ready for snacking and packing!

Storage for the Muffins
The muffins store well, so make a double batch if you have a surplus of bananas! Store the cooled muffins in an airtight container at cool room temperature for 2 days, the refrigerator for 1 week, or the freezer for up to 3 months.

Happy baking!

I’m not a huge banana fan, can I substitute apple sauce for mashed banana?
That should work fine, Christiana! You may want to add a touch more sweetness since the banana is more sweet than unsweetened applesauce.
Is the sugar purely for taste? Hoping to make them without the sugar!
Hi Taylor,
The coconut sugar adds sweetness, yes, but sugar in baked goods like this also adds moisture, browning, and volume. So if you want to leave it out (you can!), I suggest adding a few more tablespoons of banana or milk (to make up for the volume).
These are excellent, thank you!
Excellent, Andrea, glad they were a success!
Delicious and so easy.
So happy to hear it,Lia!
Easy and delicious with great texture!
Thank you, Camilla.
I am so glad they were a success, June!
I used coconut butter and premade oats flour and they are delicious.
OH, wonderful, I am so happy to know that the coconut butter worked, Sithra!
Came out great, thanks.
Yay, so glad to hear it, Matt!
Just whipped these up using cashew butter (cannot do peanuts). Came out perfect! Breakfasts made for several days 😊
I am so glad they turned out well for you, Linda!
