Preheat and Prepare
– Preheat the oven to 375°F (190°C).
– Prepare the muffin tin by lining it with paper liners or greasing it.
Mix Dry Ingredients
– In a bowl, whisk together 2 cups of all-purpose flour, 1 tablespoon of baking powder, 1/2 teaspoon of salt, and 1/2 cup of granulated sugar.
– Make sure there are no lumps for a smooth muffin.

– Mix until the mixture is smooth and combined well.
Mix Batter
– Carefully pour the wet mixture into the dry ingredients.
– Stir gently until just combined. Do not overmix; this keeps the muffins light.
– Fold in 1 cup of blueberries gently to avoid breaking them.

Tips & Tricks
Muffin Making Tips
– Avoid overmixing for a light texture. Stir gently until the batter just comes together.
– Use room temperature ingredients for best results. This helps the batter mix smoothly and rise well.
Ingredient Substitutions
– If you don’t have buttermilk, mix regular milk with 1 tablespoon of vinegar. Let it sit for a few minutes before using.
– You can use honey or maple syrup instead of granulated sugar. This will change the flavor and moisture.
Enhancing Flavor
– Try adding a splash of vanilla extract for a warm touch.
– A hint of almond extract can add a nice twist to the muffins.
– Experiment with spices like nutmeg or ginger for added depth.
Pro Tips
- Use Fresh Ingredients: Fresh blueberries and lemons will enhance the flavor of your muffins significantly. If using frozen blueberries, do not thaw them to prevent the batter from becoming too wet.
- Don’t Overmix: Mix the batter until just combined to keep the muffins light and fluffy. Overmixing can lead to dense muffins.
- Chill the Butter: For the best streusel topping, ensure your butter is cold when cutting it into the flour mixture. This helps create a crumbly texture.
- Check for Doneness: Use a toothpick to test the muffins; it should come out clean or with a few crumbs attached, but not wet batter.
Variations
Fruit Variations
You can change the fruit in these muffins. Instead of blueberries, try using raspberries or blackberries. Both fruits add a burst of flavor. You can also mix fruits together for fun. Adding nuts or seeds gives muffins a nice crunch. Chopped walnuts or sunflower seeds work well. They add texture and nutrition.
Dietary Adjustments
If you need a gluten-free version, swap all-purpose flour for a gluten-free blend. Make sure it has xanthan gum for the right texture. For a vegan twist, use plant-based milk and replace the egg with a flax egg. Simply mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit for a few minutes to thicken. These changes keep the muffins tasty for everyone.
Flavor Twists
Want to change the flavor? Try adding lime or orange zest instead of lemon. Each citrus brings a different taste. You can also mix in herbs like thyme or basil. These herbs add a fresh taste that surprises the palate. Experimenting with flavors can lead to new favorites.
Storage Information
Best Storage Practices
To keep your lemon blueberry streusel muffins fresh, store them in an airtight container. This helps lock in moisture and flavor. If you don’t have one, you can use a zip-top bag. Just make sure to squeeze out as much air as possible before sealing. Keep the muffins at room temperature for up to two days. If you need to store them longer, consider freezing them.
Freezing Instructions
To freeze your muffins, first allow them to cool completely. Place them in a single layer on a baking sheet and freeze for about an hour. Once frozen, transfer them to an airtight container or a freezer bag. Label the bag with the date. When you want to enjoy them, remove a muffin from the freezer. Reheat it in the microwave for about 30 seconds. This will help restore the soft texture.
Shelf Life
These muffins last about two days at room temperature. If you store them in the fridge, they can last for up to a week. Look for signs of spoilage, like mold or an off smell. If the muffins feel dry or hard, they may not taste good anymore. Always trust your senses when it comes to food safety.
FAQs
Can I make these muffins without buttermilk?
Yes, you can! If you don’t have buttermilk, mix regular milk with 1 tablespoon of vinegar. Let it sit for about 5 minutes. This creates a similar tangy flavor that works well in the recipe. You can also use plain yogurt diluted with a little water. Both options will keep your muffins moist and delicious.
What can I do if my muffins are dense?
If your muffins turn out dense, check a few things. First, ensure you measure your flour correctly. Too much flour makes them heavy. Use the spoon and level method. Also, mix the batter just until combined. Overmixing can make muffins tough. Finally, make sure your baking powder is fresh. Old baking powder won’t help the muffins rise.
How do I know when the muffins are done?
To test if your muffins are done, use a toothpick. Insert it into the center of a muffin. If it comes out clean or with a few crumbs, they are ready. If wet batter sticks to it, bake them a bit longer. You can also check the tops; they should be golden brown and spring back when lightly touched.
Can I use frozen blueberries?
Absolutely! You can use frozen blueberries in your muffins. Just don’t thaw them; add them straight from the freezer. This helps keep the muffins from turning blue and soggy. Frozen berries also add a nice chill to your muffins.
