Baking Tips for Success
- Banana Hack: Unripe bananas? No problem! Baking them at 300°F for 20 minutes softens them and adds a hint of sweetness, though overripe (brown-spotted) bananas will give the best flavor next time.
- Dome Secret: The initial 425°F blast helps the muffins rise quickly, setting that beautiful dome. Don’t open the oven during the first 5 minutes!
- Moisture Check: If the batter feels too thick with less milk, add 1-2 tablespoons more, but the ¼ cup should keep these muffins just right.
- Add-Ins: Chocolate chips or toasted walnuts add a delightful crunch—try a mix of both for fun!
- Storage: Store at room temperature for 3 days, refrigerate for a week, or freeze for 3 months. Pop frozen muffins in the microwave for 20-30 seconds to reheat.

Baking Science 101
The high initial temperature (425°F) causes the baking powder and soda to react quickly, pushing the batter upward for that domed top. The shift to 375°F ensures the insides bake evenly without drying out. The reduced milk (¼ cup) balances the banana liquid, preventing a soggy crumb while keeping these muffins tender.
FAQs
- Why 15 muffins?: This yield worked for all our tests with a standard tin. For 12 larger muffins, use my DIY Tulip Liner hack and fill only 12 cups or use a jumbo tin.
- Can I use gluten-free flour?: Yes! Substitute with a 1:1 gluten-free baking flour and add ¼ teaspoon xanthan gum if your blend doesn’t include it.
- Too sweet?: Reduce brown sugar to ½ cup (100g) if you prefer a less sweet muffin.

- ¼ cup milk 60 g
- ½ cup salted butter, melted & cooled slightly 115 g
- 2 large eggs room temperature
- 2 tsp vanilla extract
- 1 ½ tsp baking powder
- 1 tsp baking soda
- 1 ½ tsp ground cinnamon
- ¼ tsp ground nutmeg
- ¾ tsp salt
- 1 cup chocolate chips, chopped nuts or dried fruit (optional) 160 g
Instructions
- Preheat & Prep: Preheat your oven to 400°F (205°C) for the first 5 minutes to encourage a domed rise, then lower to 375°F (190°C). Line a muffin tin with 15 paper liners (use two 12-cup tins if needed) or grease lightly.
- Mix Dry Ingredients: In a large bowl, whisk together oats, flour, brown sugar, baking powder, baking soda, cinnamon, nutmeg, and salt.
- Prepare Bananas: If using unripe bananas, bake them whole (in their skins) at 300°F (149°C) for 20 minutes to soften and enhance sweetness, then mash to measure 1 ½ cups (360g). For ripe or frozen bananas, thaw and mash with their liquid.
- Mix Wet Ingredients: In a medium bowl, whisk mashed bananas, milk, melted butter, eggs, and vanilla extract until smooth.
- Combine Wet & Dry: Stir wet ingredients into dry until just combined (avoid over-mixing). Fold in optional add-ins.
- Scoop Muffins: Divide batter evenly among 15 muffin cups, filling each about ¾ full. Mound the batter slightly in the center for a taller top.
- Bake: Bake at 425°F (220°C) for 5 minutes, then reduce to 375°F (190°C) without opening the oven door. Bake for 15-19 minutes more (total 20-24 minutes), until a toothpick comes out clean. Check at 20 minutes to avoid overbaking.
- Cool and Serve: Cool in the tin for 5 minutes, then transfer to a wire rack. Serve warm with smear of butter.
