- 1 ½ cups all-purpose flour (about 235 grams): The base for our muffins; it provides structure.

- ½ teaspoon salt: Enhances all the flavors.

How to Make Streusel-Topped Banana Nut Muffins
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or grease with non-stick spray.
- Make the Streusel Topping: In a medium bowl, mix together the oats, chopped walnuts, and cinnamon until well combined. Set aside to allow the flavors to meld together.
- Combine Wet Ingredients: In a large mixing bowl, use an electric mixer to cream together the softened unsalted butter, granulated sugar, and brown sugar until light and fluffy. Beat in the eggs, one at a time, then mix in the Greek yogurt and vanilla bean paste or extract until fully incorporated.
- Prepare Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and cinnamon. This step ensures even distribution of the leavening agents throughout the muffins.
- Combine & Fold: Gradually add the dry mixture to the wet mixture, mixing just until combined. Be careful not to over-mix—lumps are okay!
- Add Bananas & Nuts: Gently fold in the mashed bananas and chopped walnuts, ensuring they are evenly distributed throughout the batter.
- Fill Muffin Tins: Spoon the batter into the prepared muffin tin, filling each cup about two-thirds full. Sprinkle a generous amount of the streusel topping over each muffin.
- Bake: Place the muffin tin in the preheated oven and bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean and the tops are golden brown.
- Cool: Allow the muffins to cool in the tin for about 5 minutes, then transfer them to a wire rack to cool completely.
Storing & Reheating
Store your Streusel-Topped Banana Nut Muffins at room temperature in an airtight container for up to 2 days. If you want them to last longer, pop them in the refrigerator where they’ll stay fresh for up to a week. For long-term storage, freeze them in a ziptop bag for up to 3 months. When you’re ready to enjoy, simply reheat them in the microwave for 10-15 seconds or in a preheated oven at 350°F (175°C) for about 5-7 minutes. Note that while freezing may slightly alter the texture, these muffins will still be delicious!
Chef’s Helpful Tips
- Ensure that your bananas are very ripe; brown spots mean more sweetness, which is key for excellent flavor.
- Use room temperature ingredients, including eggs and yogurt, to help everything mix smoothly and create a tender crumb.
- Avoid over-mixing the batter to prevent dense muffins. It’s okay if some lumps remain!
- Feel free to play around with the nuts; pecans or hazelnuts can also add a lovely twist.
- For extra flavor, consider adding chocolate chips or a sprinkle of nutmeg!
