Method: Banana Blueberry Muffins (Use Fresh or Frozen Blueberries!)

Creating these muffins is a breeze when you follow these simple steps:
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line a muffin tin with liners or spray it with cooking spray to prevent sticking.
2. Combine Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, baking powder, salt, nutmeg, and cinnamon. Set aside.
3. Mix Wet Ingredients
In a medium mixing bowl, combine the melted butter, light brown sugar, and granulated sugar. Mix until well combined. Then add the eggs, vanilla extract, sour cream, and mashed ripe banana. Whisk until the mixture is smooth and creamy.
4. Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry ingredients. Gently fold the mixture with a rubber spatula until just combined. Be careful not to overmix; a few lumps are perfectly fine.
5. Add Blueberries and Walnuts
Gently fold in the blueberries and toasted walnuts, ensuring they are evenly distributed throughout the batter.
6. Fill the Muffin Tin
Spoon the batter into the prepared muffin tin, filling each cup about 2/3 full. If desired, sprinkle the tops with sparkling sugar for a delightful crunch.
7. Bake
Bake in the preheated oven for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. The tops should be golden brown and spring back when lightly pressed.
8. Cool and Enjoy
Remove the muffins from the oven and allow them to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. Enjoy warm or at room temperature!
Easy Ingredient Swaps

If you’re looking to switch things up or cater to dietary needs, consider these easy swaps:
- For a dairy-free version, substitute the buttermilk and sour cream with plant-based alternatives like almond milk yogurt and coconut milk.
- Replace the all-purpose flour with whole wheat flour for a healthier option.
- Use maple syrup instead of granulated sugar for a natural sweetener.
- Add a teaspoon of lemon zest for a refreshing citrus twist.
Troubleshooting Tips
If you encounter any issues while baking, here are some helpful tips:
- If your muffins are too dense, you may have overmixed the batter. Mix until just combined for a lighter texture.
- In case your muffins come out dry, check your oven temperature. An oven thermometer can help ensure accurate baking temperatures.
- If you notice the tops browning too quickly, cover them loosely with aluminum foil halfway through baking.
- For perfectly domed muffins, avoid opening the oven door during the first 15 minutes of baking.
Refrigerate, Freeze, Reheat
These Banana Blueberry Muffins (Use Fresh or Frozen Blueberries!) store beautifully:
To refrigerate, place the muffins in an airtight container for up to one week. For longer storage, you can freeze them. Wrap each muffin tightly in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to three months.
To reheat, simply microwave a muffin for about 15-20 seconds, or warm them in the oven at 350°F (175°C) for about 10 minutes until heated through.

How can I tell when the muffins are done baking?

Can I make these muffins ahead of time?
