These banana oatmeal muffins 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 muffins!

Why You’ll Love This Banana Oatmeal Muffin Recipe
- So easy to make
- Nutritious and delicious
- Make ahead and freezer friendly
- Even your toddler will love them!
Ingredients & Variations
- 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. You can also use maple syrup!
- Vanilla extract – vanilla extract adds delicate flavor.
- Salt – salt enhances flavor.
- Walnuts (optional) – walnuts add texture, flavor and protein! 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).

My Pro Tip
Pro Tips
Use dairy or non-dairy milk. I use non-fat milk.
For sweeter muffins, 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!

Frequently Asked Questions
Quick oats can make your oatmeal cups dry.
Reheat oatmeal cups in a foil package in the oven at 375 degrees for 10-15 minutes (best option), or on a plate in the microwave for 45 seconds. They are also delicious served chilled!
Store in the fridge, in an airtight container, for up to 5 days.
Yes! Freeze muffins in a freezer safe container after they’ve cooled. Thaw in the fridge or at room temperature.
I don’t recommend this. Quick oats can make your banana oatmeal muffins dry.

Banana Oatmeal Muffins
Equipment
- muffin pan
Ingredients
- 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
Instructions
- Preheat oven to 350℉. 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)!
