Things You'll Need

  • 3 very ripe bananas (or 1 cup of applesauce)

  • 1 cup milk (dairy, coconut, or almond)

  • 1/2 cup peanut butter (or any nut butter)

  • 2 eggs

  • 1/4 cup maple syrup (or honey)

  • 1 teaspoon vanilla

  • 1 tablespoon baking powder

  • 1/4 cup flaxseed (ground)

  • 1 tablespoon chia seeds

Tip

The peanut butter-banana base can be adapted to suit many different tastes. Applesauce works in place of bananas and any nut butter can pinch hit for the peanut butter.

Get Started

Set your oven to 375 degrees F and grease the muffin pan. Use coconut oil, spray or butter to grease your pan. Next, mash your bananas in a large mixing bowl.

When it comes to baking with bananas, the browner the better. They'll have more flavor.

A potato masher works best but a fork would also do for very ripe bananas.

Prepare to Bake

Fill muffin cups to the top. A 3-ounce ice cream scoop works perfectly for evenly distributing muffin batter into pans. This is the time to add optional toppings such as chocolate chips or banana chips.

Tip: Place a couple of chocolate or banana chips in the bottom of each cup before ladling in the batter.
