1 cup (250g) mashed ripe bananas
Add the sugar and whisk together until they’re well combined.
1 1/4 cup (250g) light brown sugar
Then add the oil and whisk until it's all well combined.
1/2 cup (120mL) oil
Add in one egg and whisk until it’s well combined and has lightened in color, about 30-60 seconds. Repeat with the next two eggs, one at a time.
3 large eggs
Add in the Greek Yogurt and the vanilla extract and whisk until it’s completely smooth.
3/4 cup (170g) Greek Yogurt, 1 Tbsp pure vanilla extract
Add in the flour, baking powder, baking soda, salt and cinnamon and whisk just until the last streak of flour is incorporated.
2 1/2 cups (300g) all-purpose flour, 1 Tbsp baking powder, 1/2 tsp baking soda, 1/2 tsp fine sea salt, 1 1/2 tsp cinnamon

Preheat the oven to 425F (218C) and line 12 muffins tins.
Use a large cookie scooper to fill the muffins tins to the top, the batter should be enough for 12 large muffins.
Sprinkle each muffin with 1-2 tsp of raw sugar for a crispy muffin top.
2-3 Tbsp raw or granulated sugar
Bake for 5 minutes then reduce the oven temperature to 375F (190C) and bake for 10-12 minutes, just until the muffins are golden brown and spring back when you press on the center gently.
Remove from the oven and allow to cool for at least 10-20 minutes before serving.
