I love cooked or baked blueberries. I don't like fresh blueberries for some reason. Maybe texture? I don't know why, but I really like them cooked or baked so I made some muffins with blubes! Lemons add such a brightness to baked goods, so that was easy to decide.
Lemon Blueberry Muffins
1 3/4 cups flour, plus 1 Tablespoon reserved
1 teaspoon baking powder
1 teaspoon baking soda
1/2 teaspoon salt
6 Tablespoons butter, room temperature
3/4 cup sugar
1 Tablespoon lemon zest, you'll likely need 2 lemons altogether
2 eggs
1/2 cup sour cream
1 1/2 teaspoon vanilla
1/4 cup lemon juice
2 Tablespoons milk
1 1/2 cups blueberries
Crumb Topping
1/3 cup flour
2 teaspoons brown sugar
1 teaspoon lemon zest
2 Tablespoons melted butter
Preheat the oven to 425°. Spray a muffin pan with Pam. I used a silicone muffin "pan" that I set in a regular muffin pan for stability. I sprayed it with Pam.
Place the butter in a stand mixer and beat with the paddle.
While it is beating zest 2 lemons and squeeze the juice through a strainer to keep the seeds out.
Wash and dry the blueberries and put them in a medium bowl. Sprinkle the reserved Tablespoon of flour over the blueberries and mix. This should help to keep them all from sinking to the bottom of the muffins. Set aside.
Put the flour, baking soda, baking powder and salt in a medium bowl and whisk it together. Set aside.
Scrape down the butter as it is beating until fluffy and light. Add the sugar and lemon zest to the butter and beat some more. Then beat in the eggs, sour cream and vanilla. Next add the milk and lemon juice and keep mixing.
Add the flour mixture and blend it until all the flour is incorporated.
Don't over mix.
Remove the mixing bowl from the mixer. Fold in the blueberries.

Use a large cookie scoop to fill each muffin cup to the top.
Make the crumb topping.
In a small bowl melt the butter in the microwave. Cover it with a paper towel so it doesn't spit all over the inside of the microwave.
Add the flour, brown sugar and zest. To be honest I just used the last of the zest from the two lemons I zested. It was probably a bit more than 1 teaspoon.
Mix with a fork until well blended.
Sprinkle the tops of the muffins with the crumb topping and gently press down.
Here is the tricky part that I learned from reading it on Sally's Baking Addiction. Bake for 5 minutes at 425°. Then without removing the muffins, lower the temperature to 350°. This technique is to make the tops bake up tall. Bake for an additional 15 to 20 minutes or until the muffins are golden brown on top and a tester comes out clean.
Let cool for 5 minutes in the pan and remove to a cooling rack.
These muffins were lemony and filled with the creamy sweetness of the blueberries. And at just the right texture!
