I've been in my fair share of kitchens where butter was a luxury—or just not an option. That's how I stumbled onto these muffins. They're everything you want in a baked good: tender, golden, and packed with banana flavor, but without a single stick of butter in sight.

The secret? Greek yogurt and a good glug of olive oil. They bring the fat and moisture that butter usually provides, but with a tangy twist and a healthier profile. And the oats? They give the muffins a hearty, rustic texture that'll keep you full till lunch.
Whether you're out of butter, baking for someone with a dairy sensitivity, or just looking to lighten up your morning routine, these muffins deliver. No fuss, no fancy equipment—just a bowl, a whisk, and a hot oven.
Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (180g) whole wheat flour
Whole wheat adds a nutty flavor and more fiber. All-purpose works too, but the muffins will be less dense.
1 cup (90g) old-fashioned rolled oats
Use certified gluten-free oats if needed. Quick oats can be used, but the texture will be softer.
1 teaspoon baking soda
Make sure it's fresh for proper rise. If you're out, use 3 teaspoons baking powder.
1/2 teaspoon salt
Fine sea salt or kosher salt both work.
1 teaspoon ground cinnamon
Fresh cinnamon is more aromatic. You can also add a pinch of nutmeg or cardamom.
3 ripe bananas, mashed (about 1 1/2 cups)
The riper, the better—brown spots mean more sweetness. If you only have underripe, add an extra tablespoon of maple syrup.
1/2 cup (120g) plain Greek yogurt
Use full-fat or 2% for best moisture. Non-fat works but may be less tender. Vegan? Use coconut yogurt.
1/3 cup (80ml) olive oil or melted coconut oil
Olive oil gives a subtle fruity note; coconut oil makes them more neutral. Both keep the muffins moist without butter.
1/2 cup (120ml) maple syrup or honey
Maple syrup adds a warm flavor. Honey works too, but it's sweeter, so you can reduce to 1/3 cup.
2 large eggs
Room temperature eggs blend better. For a flax egg, mix 1 tablespoon ground flax with 3 tablespoons water per egg.
1 teaspoon vanilla extract
Pure vanilla extract is best, but imitation works in a pinch.
1/2 cup (60g) chopped walnuts or chocolate chips (optional)
Walnuts add crunch, chocolate chips add indulgence. Both are optional—use what you have.
Tips & Tricks
- Don't overmix the batter. Stir until just combined—lumps are fine. Overmixing develops gluten and makes muffins tough and rubbery.
- Use an ice cream scoop for even, uniform muffins. This ensures they bake evenly and look professional.
- Check for doneness with a toothpick inserted into the center—it should come out with a few moist crumbs, not wet batter. If the tops are browning too fast, tent with foil.
Pro Tips
Step-by-Step Instructions
1. Preheat and prep
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease with a little oil.
2. Mix dry ingredients
In a large bowl, whisk together the whole wheat flour, oats, baking soda, salt, and cinnamon until evenly combined.
3. Combine wet ingredients
In a separate bowl, mash the bananas until mostly smooth. Whisk in the Greek yogurt, olive oil, maple syrup, eggs, and vanilla extract until the mixture is well blended.
4. Fold wet into dry
Pour the wet mixture into the dry ingredients. Gently fold with a spatula until just moistened—lumps are okay. If using, fold in nuts or chocolate chips.
5. Fill muffin cups
Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full. Use a spoon or ice cream scoop for clean portions.
6. Bake to perfection
Bake for 18-22 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out with a few moist crumbs. The internal temperature should read 200°F (93°C).
7. Cool and enjoy
Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.
Delicious Variations
Blueberry Banana
Fold in 1 cup fresh or frozen blueberries (toss in a little flour to prevent sinking).
Chocolate Chip
Swap the walnuts for 1/2 cup chocolate chips and add an extra tablespoon of maple syrup for sweetness.
Spiced Pumpkin
Replace one banana with 1/2 cup pumpkin puree and add 1/2 teaspoon pumpkin pie spice.
How to Store No-Butter Banana Oat Muffins
Refrigerator
Store in an airtight container in the fridge for up to 5 days. Let come to room temperature or warm before serving.
Freezer
Wrap individually in plastic wrap, then place in a freezer bag. Freeze for up to 3 months. Thaw overnight in the fridge or microwave for 30 seconds.
Reheating
Reheat in the microwave for 20-30 seconds, or in a toaster oven at 350°F (175°C) for 5-7 minutes to refresh crisp edges.
Frequently Asked Questions
Q: Can I use all-purpose flour instead of whole wheat?
Yes, you can substitute an equal amount of all-purpose flour, but the muffins will be less dense and slightly lighter in texture. Whole wheat gives a heartier, nuttier flavor.
Q: Can I make these muffins vegan?
Absolutely. Use a flax egg (1 tablespoon ground flax mixed with 3 tablespoons water per egg), and replace the Greek yogurt with a plant-based yogurt like coconut or almond. The olive oil and maple syrup are already vegan.
Q: How ripe should the bananas be?
The riper, the better—look for bananas with brown spots or fully brown skins. They're sweeter and mash more easily. If your bananas are still green, you can roast them in the oven at 300°F (150°C) for 15 minutes to speed up ripening.
Q: Why did my muffins sink in the middle?
Sinking often happens if the batter is overmixed or if the oven temperature is too low. Make sure to fold just until combined and always preheat your oven fully. Also, avoid opening the oven door during baking.
Q: Can I reduce the sugar?
Yes, you can cut the maple syrup down to 1/3 cup (80ml) without affecting texture much, but the muffins will be less sweet. If you want to use a sugar substitute, use a 1:1 baking sweetener, but know it may alter browning.
