Prep. Line 2 muffin liners with 16 liners and set aside. If you need a recommendation, this is my favourite tin. Mash bananas in a large bowl.
In a large bowl, add in flour, cinnamon, nutmeg, cloves, ginger, allspice, salt, cornstarch, baking powder, and baking soda. Using a spatula, mix until just completely combined. Set aside
2 1/2 cups all-purpose flour, 1 tsp baking soda, 2 1/2 tsp baking powder, 1 tbsp cornstarch, 1 1/2 tsp cinnamon, 1/2 tsp cloves, 3/4 tsp ginger, 1/4 tsp nutmeg, 1/4 tsp allspice
In another large bowl, whisk mashed bananas, oil, eggs, vanilla, sour cream, molasses, and brown sugar. Whisk until well combined. There may be lumps from the bananas but that is okay.
1 1/4 cups bananas, 1/2 cup oil, 3 eggs, 1/2 cup full fat sour cream, 1/4 cup molasses, 1 tbsp vanilla, 1 cup dark brown sugar
Combine the dry with the wet and using a spatula, gently fold until it's just combined and no flour streaks appear. Don't over-mix!
Evenly divide the batter between 16 liners, they should be almost or all the way full. Using a cookie scooper helps big time to minimize the mess. In a small cup, add in a pinch of cinnamon, nutmeg, allspice, cloves, and 1 tbsp of white sugar. Mix this together and then sprinkle on top of the muffins.
1 tbsp white sugar, Pinch of cinnamon, Pinch of allspice, Pinch of cloves, Pinch of nutmeg
Bake the muffins at 375°F for 15-17 minutes. The muffins are ready when a toothpick inserted comes out dry with no wet batter.
These muffins stay fresh covered at room temperature for a few days, or in the refrigerator in an airtight container for up to 1 week!
