Perfect Blueberry Muffins

We were in Chicago visiting our daughter Amber. One morning she made the best blueberry muffins I have ever eaten. They were perfect. A hint of lemon, tender crumb, juicy berries and a tasty streusel topping. What's not to like? I asked for the recipe, that's just what we do. She explained it was on Our Best Bites. What? I look at that site every day. Somehow I had missed it.
I hesitated to make them at home. Food always tastes better when someone bakes it for you and Amber lives at sea level, we live above 5000 feet. But I tried the recipe and I'm happy to say the muffins turned out perfect. This recipe is a keeper. Thank you, Our Best Bites!

Streusel-Topped Blueberry Muffins or Perfect Blueberry Muffins
Recipe from Our Best Bites

1 3/4 c. all-purpose flour
2 3/4 tsp. baking powder
3/4 tsp. table salt
1/2 c. sugar
2 tsp. grated orange or lemon peel
1 large egg
3/4 c. buttermilk
1/3 c. canola oil
1 c. fresh or frozen blueberries
1 Tbsp. flour
1 Tbsp. sugar

Streusel Topping
1/4 c. sugar
2 1/2 Tbsp. flour
1/2 tsp. cinnamon
1 1/2 Tbsp. butter

Preheat oven to 400 degrees. Combine flour, baking powder, salt, sugar and citrus peel is large bowl and stir. Make a well in the center of the mixture. In a smaller bowl, whisk together the egg, buttermilk, and oil. Add to the dry ingredients, stirring just until moistened.

In a small bowl, combine the remaining flour and sugar and then toss the blueberries in this mixture until they are well-coated. Gently fold the blueberry mixture into the batter. Spoon the batter into lined muffin tins, filling 2/3 full.

To make the streusel topping, combine the 1/4 c. sugar, 2 1/2 Tbsp. flour, and cinnamon. Cut in the butter with a pastry cutter or two butter knives until the mixture is crumbly. Sprinkle over the batter and bake for 18 minutes or until the tops are golden and a toothpick inserted into the center of one of the muffins comes out clean. Remove from oven and allow to cool in the pan for 5 minutes and then transfer to a cooling rack. Makes 12 muffins.
