- Preheat the oven to 400F. Line a Vida by PADERNO Silicone Non-Stick Muffin Pan, 12-cup tin with paper liners. Whisk flour with pecans (if using), baking powder and salt in a large bowl.
- In a separate bowl, mash overripe bananas very well (you should have about 1 cup of mash). Stir in the brown sugar, oil, egg and lemon zest. Stir in milk and lemon juice.
- Reserve 3 to 4 strawberries for topping, then chop the rest.
- Add liquid mixture into flour mixture. Using a rubber spatula, stir until just combined. Add chopped strawberries and stir until just combined.
- Immediately spoon or scoop muffin batter into the prepared tin. Top each muffin with some sliced strawberry and banana, tapping each piece gently into the muffin batter.
- Bake for 5 min then reduce heat to 350F and bake for another 15 - 20 min, or until muffin tops are golden and a cake tester inserted into the centre of a muffin comes out clean. Let cool in the pan for 10 min then transfer to a rack to cool completely.
Make ahead: Freeze cooled muffins in a zip-lock bag for up to 4 weeks. Thaw at room temperature.
