If you are looking for more quick & easy breakfast ideas, look no further than my peanut butter banana oatmeal bars, or my protein baked oats.

Why You'll Love This Recipe

• They are literally made with only 3 ingredients- so simple and quick! I don't count the water/milk because well everyone should have access to water at their sink.
• They're customizable- add in things like vanilla extract, blueberries, peanut butter, or chocolate chips to spice things up! Whatever you have on hand.
• The only sweetener in this recipe is ripe bananas! Perfect way to use up bananas that are going bad.
• They are perfect for meal prepping since they last in the fridge all week.
• These are allergen-friendly, plant based, and have no added sugar.

Ingredients

This list is short and sweet, and all things you probably already have on hand ! Find ingredient notes (including substitutions and swaps) below.

• Oats- I used old-fashioned oats blended up as my "oat flour", make sure to blend them to a fine crumb. You can also buy oat flour if you'd like!
• Bananas- the more ripe they are, the better (think like banana bread ripe)! Ripe bananas act as our sweetener and binding agent in this recipe, while adding moisture.
• Baking powder- as our levening agent, this is going to add a bit of height to our muffins.
• Milk/water- I like adding water or milk for extra moisture to make sure the muffins aren't too dry.

How to Make 3 Ingredient Muffins

This recipe is so easy to make. Follow along below.

Mash the bananas with a fork until no clumps remain.

If using whole oats, blend in a food processor until you have a fine crumb.

Mix oat flour with baking powder, then add in the bananas and milk/water. Mix until fully combined. If adding any add-ins, do that now.

Scoop into a greased muffin tin and bake for 15-18 minutes, or until a toothpick comes out clean.

FYI- These muffins are pretty dense/not as fluffy as traditional muffins. I filled my muffin tins about halfway, but if you want taller muffins, fill them to the top (this will make less muffins).

Recipe Substitutions and Variations

• Any kind of oats will work in this recipe! Just be sure to grind them down to almost a powder form. I used a food processor to do this, but you could also use a high-powdered blender.
• Make these sweeter by adding some honey, maple syrup, or coconut sugar to the batter.
• Add in ideas:
  • vanilla extract, salt, cinnamon, nutmeg, pumpkin pie spice
  • chocolate chips or chopped chocolate bar, blueberries, raspberries, strawberries, chopped nuts
  • peanut butter, almond butter, chia seeds

Equipment Needed

A good quality muffin pan is needed for making any muffin or cupcake recipe- you'd be surprised how the pan can make a hug difference!

I have this food processor that I used to grind up my oats into oat flour.

Anytime you are making muffins, make sure to really grease your muffin tin so that they pop out easily after being baked. I love using a baking spray that has flour in it.

How To Store

These muffins will stay good in an airtight container for 3-4 days at room temperature and up to a week in the fridge.

You can also freeze them for up to 4 months. To defrost, allow them to sit at room temperature until thawed.

What if my bananas aren't ripe?

There are a couple of ways you can ripen bananas quickly- If you want to make these muffins in a few days from now, close the bananas in a brown paper bag and they will ripen faster. Otherwise, you can ripen them in the oven by baking the unpeeled bananas for 20-30 minutes (in a 300F oven). They should come out brown/black and very squishy. Let them cool completely before using for this recipe.
