Blueberry Muffins

Andrew & Matthew Roach

Streusel Topping
3 T white sugar
3 T brown sugar
1/3 cup flour
5 T melted butter

Blueberry Swirl
1 cup fresh blueberries
1 teaspoon sugar
1 tablespoon water

Muffins
2 1/2 cups unbleached all-purpose flour
1 1/8 cups sugar
2 1/2 teaspoons baking powder
1 teaspoon table salt
2 large eggs
4 tablespoons (1/2 stick) unsalted butter, melted and cooled slightly
1/4 cup vegetable oil
1 cup buttermilk
2 teaspoons vanilla extract

Directions:

Combine stresuel ingredients until it is the size of peas and set aside.

Adjust oven rack to middle position and heat oven to 425 degrees. If your oven cooks on the hot side normally, reduce the heat.

Prepare standard muffin tins with nonstick cooking spray or liners. Bring 1 cup blueberries, water, and 1 teaspoon sugar to simmer in small saucepan over medium heat. Cook, mashing the berries with your potato masher or fork several times and stirring frequently, until berries have broken down and mixture is thickened and reduced by about half. This wil take about 6 minutes. Transfer to small bowl and cool to room temperature, 10 to 15 minutes.

Whisk flour, baking powder and salt together in large bowl. Whisk remaining sugar and eggs together in medium bowl until thick and well combined. Slowly mix in butter and oil until combined. Whisk in buttermilk and vanilla. Using rubber spatula, fold egg mixture and remaining cup blueberries into flour mixture until just moistened. (Batter will be very lumpy with few spots of dry flour; do not overmix.)

Using a cookie scoop or large spoon, divide batter equally among prepared muffin cups (batter should completely fill cups and mound slightly). Spoon teaspoon of cooked berry mixture into center of each mound of batter. Using chopstick or skewer, gently swirl berry filling using figure-eight motion. Sprinkle streusel evenly over muffins.

Bake until muffin tops are golden and just firm, 17 to 19 minutes. Cool muffins in muffin tin for 5 minutes, then transfer to wire rack and cool 5 minutes before serving.
