How to make the BEST Banana Muffins

00:00 Introduction: Preheat the oven to 425°F (220°C) and line a muffin tin with paper liners. 00:13 Place the peeled bananas in a large bowl and mash them with a fork or potato masher until well‑mashed. 00:38 Add the canola oil and melted butter, stirring well. 00:55 Stir in the sugar and light brown sugar until the mixture is smooth. 01:05 Add the eggs, vanilla extract, and buttermilk, mixing thoroughly before setting aside. 01:24 In a separate bowl, whisk together the dry ingredients—flour, baking powder, baking soda, and salt. 01:42 Fold the dry mixture into the wet batter until the batter is just a bit under‑finished, then gently fold in the remaining ingredients. 02:02 Portion the batter into the prepared muffin tin, filling each liner about three‑quarters full. 02:17 For the optional streusel, combine flour, brown sugar, and salt to create a dry‑mix. 02:43 Cut the cold butter into the streusel mixture until it resembles coarse crumbs. 03:12 Bake the muffins at 425°F (218°C) for 8 minutes, then reduce the oven temperature to 350°F (175°C) and bake for an additional 7–8 minutes, testing the muffins for doneness with a toothpick. Allow the muffins to cool before serving.
