Ingredients You Will Need

Dry Ingredients:

  • 3 cups old-fashioned rolled oats 

  • 2 teaspoons baking powder 

  • 1 teaspoon cinnamon 

  • A pinch of freshly ground nutmeg 

  • 1/2 teaspoon kosher salt 

Wet Ingredients:

  • 1 cup mashed banana  (This is about 2 to 3 bananas. Remember, the browner the banana, the sweeter your muffins will be!)

  • 2 eggs

  • 1 ½ cups unsweetened almond milk  (You can substitute this with any milk of your choice).

Optional Toppings:

  • Mini chocolate chips, blueberries, raspberries, raisins, or walnuts

Step-by-Step Instructions

  1. Prep the Oven & Pan: Preheat your oven to 350°F. Spray a standard 12-cup muffin pan with coconut oil spray to ensure the muffins don't stick.

  2. Mix the Dry Ingredients: In a large bowl, combine the rolled oats, baking powder, cinnamon, nutmeg, and kosher salt. Mix everything gently and set the bowl aside.

  3. Prepare the Wet Ingredients: In a separate bowl, mash the bananas against the side until they are slightly chunky. Whisk in the eggs and your almond milk until the wet mixture is well combined .

  4. Combine Wet and Dry: Pour the wet banana mixture into your bowl of dry ingredients. Gently stir until everything is fully incorporated and you are left with a nice, moist batter.

  5. Fill the Muffin Pan: Evenly divide the batter among the 12 muffin cups. It's best to under-pour slightly at first so you can easily balance them out at the end, ensuring they all bake evenly.

  6. Add Toppings: Sprinkle some mini chocolate chips (or your favorite toppings) directly over the top of each muffin cup . You can also fold them right into the batter if you prefer!

  7. Bake: Pop the tray into the oven and bake for 20 to 25 minutes. You’ll know they are done when they have set through and boast a beautiful golden-brown top.
