Banana baked oatmeal cups (oatmeal muffins) are healthy and simple to make! They are perfect for breakfast on-the-go, since they are freezer-friendly and easy to heat in the microwave. Your whole family will love these, including the kids!

These banana baked oatmeal cups are easy to make and easy to reheat!

No flour is required to make this baked oatmeal muffin cup recipe. In fact, they are gluten free! Mashed bananas make these oatmeal cups tender and naturally sweet. There are many ways to flavor your muffin cups, but I love adding walnuts for a delicious banana nut version, or you can add a dollop of peanut butter for another delicious way to enjoy banana oatmeal cups!

Ingredients for Banana Baked Oatmeal Muffin Cups

  • Old-fashioned rolled oats – rolled oats provide the best texture over quick oats or steel cut oats.
  • Milk – I like non-fat milk since it is flavorless. You can use dairy or non-dairy milk!
  • Eggs – eggs help bind all ingredients together.
  • Ripe bananas – ripe bananas add natural sweetness, flavor, and take the place of oil or butter.
  • Baking powder – baking powder prevents denseness.
  • Honey – honey adds a touch sweetness and complimentary flavor. I only add a 1/4 cup honey which makes these oatmeal cups relatively low sugar and lightly sweet.
  • Vanilla extract – vanilla extract adds delicate flavor.
  • Salt – salt adds flavor.
  • Walnuts (optional) – walnuts add texture, flavor and protein!

Ingredient Substitutions

  • Milk – substitute non-dairy milk for regular milk.
  • Honey – substitute maple syrup for honey.
  • Walnuts – for a peanut butter banana version, substitute 1/3 cup peanut butter and 2/3 cup mashed banana (instead of 1 cup mashed banana and walnuts).

  • 1 muffin pan


  • 3 cups old-fashioned rolled oats
  • 1 ¼ cups milk
  • 2 large eggs
  • 1 cup ripe, well-mashed bananas
  • ¼ cup honey
  • 1 teaspoon baking powder
  • 1 teaspoon vanilla extract
  • 1 teaspoon salt
  • 1 cup chopped walnuts optional


  • Preheat oven to 350 degrees.
  • Grease a muffin pan with nonstick spray. You can use muffin cup liners but a sprayed muffin pan works best.
  • In a large bowl, add rolled oats, eggs, mashed banana, honey, baking powder, and salt. Stir until combined.
  • Add vanilla extract, milk, and walnuts. Stir until combined. Mixture will look loose and runny.
  • Immediately spoon mixture into muffin pan, filling each almost to the top. Make sure each muffin has an equal amount of liquid and dry ingredients.
  • Bake for 25-30 minutes until muffins are just set (no liquid) and are lightly golden brown.
  • Let cool in the muffin pan for 10 minutes before loosening with a knife.
  • Serve warm, room temperature or chilled (like overnight oats)!
  • After cooling completely, store in the fridge for up to a week. Freeze any leftovers.



  • About 3 bananas equal 1 cup of mashed banana. Measure for accuracy!
  • Use dairy or non-dairy milk. I use non-fat milk.
  • For sweeter oatmeal cups, use 1/3 cup honey.
  • As soon as milk is added, immediately spoon mixture in muffin pan and bake. You don’t want the milk to absorb into the oats until they bake!
