Mornings in my house are a full-contact sport: a toddler demanding toast now, an elderly dog having an accident on the kitchen floor (!), and me trying to remember if I already made my coffee or just thought about it. That’s why I’m always grateful to have these oatmeal banana muffins on hand.

They’re wholesome, made with better-for-you ingredients like oats, avocado oil, and whole wheat flour—but still tender, lightly sweet, and satisfying. Basically, they’re the unicorn of weekday muffins. After four rounds of recipe testing (because I was determined to get the flavor and texture just right), these have officially earned a spot in our healthy muffin recipe rotation.

And trust me—they’re not just for toddlers. These muffins are perfect for post-run refuels, after-school snacks, and those 3 p.m. coffee breaks we all wish happened more often.

Ingredients and Substitutions

These muffins are made with simple pantry staples and a few wholesome swaps to keep them lighter without sacrificing flavor. Here’s what you’ll need, plus a few easy substitutions:

Overripe bananas – Bananas with lots of brown spots are the secret to natural sweetness, moist texture, and rich banana flavor. The riper, the better.

Avocado oil – A heart-healthy, neutral oil that keeps these muffins soft without overpowering the flavor. Canola or another mild vegetable oil also works well.

Milk – Adds moisture and helps create a tender crumb. Use whatever you have—dairy or non-dairy (like oat, almond, or soy milk) all do the trick.

Organic cane sugar – Lightly refined with a subtle molasses flavor. Or use half white sugar and half light brown sugar if that’s what’s in your pantry.

Eggs – These bind the muffins together and help them rise. Make sure they’re at room temperature for best results.

Pure vanilla extract – Rounds out the flavors with a warm, cozy note.

Whole wheat pastry flour or all-purpose flour – Whole wheat pastry flour adds a delicate nuttiness and boosts the nutrition without weighing the muffins down. All-purpose works just as well.

Ground cinnamon – Adds warm, subtle spice that pairs perfectly with banana.

Baking powder + baking soda – The leavening agents that give the muffins their soft rise.

Salt – Balances and enhances the sweetness and spice.

Old-fashioned rolled oats – For heartiness and texture. Quick oats can work, but rolled oats hold up best.

Chocolate chips (optional) – For a bit of sweetness and fun. Leave them out for a more classic banana oatmeal muffin.

How to Make Banana Oatmeal Muffins

For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.

Step 1: Prepare.

Preheat your oven to 425°F. Line a muffin tin with paper liners. Optional: Use two tins and space out the liners for a higher rise.

Step 2: Combine Wet Ingredients.

In a large mixing bowl, whisk together the mashed bananas, oil, milk, sugar, eggs, and vanilla until smooth.

Step 3: Combine Dry Ingredients.

In a separate bowl, whisk together the flour, cinnamon, baking powder, baking soda, and salt.

Step 4: Combine Wet and Dry Ingredients.

Add the dry ingredients and oats to the wet mixture and whisk until just combined.

Step 5: Add Chocolate Chips (Optional).

If using, fold in chocolate chips.

Step 6: Let the Batter Rest.

Let the batter rest at room temperature for 5 minutes.

Step 7: Fill Muffin Cups.

Divide the batter evenly between 12 muffin cups—they will be full.

Step 8: Bake.

Bake at 425°F for 5 minutes, then reduce the heat to 350°F and bake for another 14–16 minutes, or until a toothpick comes out clean. Cool the muffins in the pan for 10-15 minutes, then enjoy or transfer to a cooling rack to cool completely.

Recipe Pro-Tips

• Space out liners. For the highest rise, use two muffin tins and leave every other cup empty—this improves airflow and encourages beautiful, well-risen domes.
• Use super-ripe bananas. The more brown and spotty, the better! They're sweeter, softer, and pack more banana flavor.
• Let the batter rest. Let the batter rest for 5 minutes before baking. This gives the oats time to hydrate, making the muffins extra tender and soft.
• Start hot, then lower. That initial 425°F blast gives the muffins their bakery-style dome. Lowering the heat lets them cook through without drying out.
• Don’t overmix. Stir the batter just until the flour disappears. Overmixing leads to dense, dry muffins—no one wants that.

Recipe Variations

Add some variety (or work with what you have on hand) by playing around with these easy mix-ins and swaps:

• Chopped walnuts or pecans – Add a little crunch and nutty flavor.
• Raisins – For natural sweetness and chewy texture, similar to oatmeal raisin chocolate chip cookies!
• Dark chocolate chips – For a richer, more grown-up chocolate bite.
• Double chocolate – Stir in 2–3 tablespoons of unsweetened cocoa powder with the dry ingredients and use chocolate chips for a brownie-muffin hybrid.
• Dairy-free – Use your favorite non-dairy milk like oat, almond, or soy. If adding chocolate chips, be sure they're dairy-free!
• Gluten-free – Substitute a 1:1 gluten-free flour blend and certified gluten-free oats. Let the batter rest for 30 minutes before baking, and cool the muffins completely before enjoying.

High-Altitude Instructions

Baking at elevation? No problem—just make these small tweaks to keep your muffins perfectly risen and tender:

• Reduce sugar to a heaping ½ cup
• Increase flour to 1¾ cups (210g)
• Start baking at 425°F, then reduce to 365°F after 5 minutes
• Reduce baking powder to ¾ tsp and baking soda to ¼ tsp

Storage Directions

• Storing: Store muffins in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
• Freezing: Cool completely, then store them in a freezer-safe container for up to 3 months. Let thaw at room temperature for 15–30 minutes before reheating in the toaster oven or enjoying.
