Preheat oven to 180°C (360°F) or 160°C (320°F) for fan-forced ovens. Line a 24 hole muffin tin with paper cases and spray the inside of the cases generously with oil to prevent the muffins from sticking.
In a large bowl, place in the flour and sift in the cinnamon and bi-carb soda. Then give it a quick whisk.
For the wet ingredients - In a separate bowl, whisk together the egg, milk, oil, date syrup and vanilla extract until combined. Then add in the mash banana and mix a few times.
Make a well in the flour mixture, then pour in the wet ingredients over it. Fold the mixture to combine just until there are no dry bits showing. Don't over mix the batter as this will cause tough muffins.
Using two teaspoons, scoop up the batter and place them in the muffin holes. Divide the batter evenly for 24 muffins. Bake for 10 to 12 minutes or until a skewer comes out clean when inserted in the middle.
Notes
(NOTE 1) Wholemeal flour (Whole-wheat flour) is less processed and more nutritious than plain/all-purpose flour. It's a sneaky way for us to make our little ones eat healthier. However, if you don't have any in the pantry, plain flour will work just fine. Don't worry, these muffins will still be healthy!(NOTE 2) Mild/light olive oil - Olive oil is the healthier alternative for oils. I used light olive oil as it doesn't have a strong taste, and therefore less likely to deter our little ones from eating these muffins.(NOTE 3) Date syrup - I found 3 varieties of date syrup at our local supermarket, so they're easy to find. They're stocked around the health section. Most date syrup brands are natural with no added sugar but always check the label. If you cannot find date syrup, leave it out because babies between 8 to 12 months old will still happily munch on these muffins. Toddlers are harder to trick as we subject them to more food choices at this stage, so for some sweetness, use honey or maple syrup.Leftovers - Allow the muffins to cool completely at room temperature. Transfer the muffins into an airtight container and store at room temperature for 3 days. If frozen, these muffins will be good for up to 3 months.
