Recipe ingredients

These peanut butter banana oatmeal muffins have just a few simple ingredients that can be easily substituted with what you have on hand.

Peanut butter banana muffins recipe ingredients
  • Oat flour. Oat flour is whole grain, lends a soft, tender texture and a nutty flavor. You can purchase it at the store, or see my post how to make oat flour to make it at home with oats you already have in your pantry. If you’re gluten-intolerant, make sure the package states that the contents are gluten-free.
  • Banana. You’ll need 1 cup of mashed banana, which is equivalent to 2 large or 3 medium bananas. The more ripe and spotty your bananas are, the sweeter they will be. The bananas add flavor, moisture and eliminate the need for oil in this recipe.
  • Peanut butter. The peanut butter adds flavor, helps bind the muffins together and adds protein. I highly recommend using natural peanut butter as it includes just peanuts and possibly salt.
  • Eggs. You’ll need 2 large eggs for this recipe to help bind the muffins together.
  • Almond milk. The almond milk adds moisture to the muffins. I use unsweetened almond milk, but you can substitute it with your favorite dairy or non-dairy milk.
  • Maple syrup. Pure maple syrup adds tremendous flavor and is my favorite unrefined sweetener. It can be substituted with honey or your favorite sweetener. Note that the muffins will not be as sweet if using coconut sugar, so I suggest adding up to 2 tablespoons extra.
  • Leaveners. A combination of baking powder and baking soda give the muffins they’re soft, fluffy domes.
  • Vanilla extract. Adds nice depth of flavor, but it’s completely optional.
  • Chocolate chips. Optional but highly recommended! I use mini dark chocolate chips, but you can use your favorite or omit them entirely.
