Being home from work and on my butt for the vast majority of the day, I surfed blogs quite a bit. I found this recipe somewhere online, and they were delish.
From The America's Test Kitchen Family Baking Book,
Vegetable oil spray
2 cups (10 oz) plus 1 tablespoon all-purpose flour
1 cup (4 oz) cake flour
1 cup (7 oz) sugar, plus 1 tablespoon for sprinkling (I used coarse sugar for sprinkling)
1 tablespoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
4 tablespoons (1/2 stick) unsalted butter, softened
2 large eggs
2 teaspoons fresh lemon Juice
1 teaspoon grated fresh lemon zest
1 teaspoon vanilla extract
1 1/2 cups plain low-fat yogurt (Use low-fat yogurt here; nonfat yogurt will make dry, tasteless muffins)
2 cups fresh or frozen blueberries (ATK prefers frozen wild blueberries)
1. Adjust an oven rack to the middle position and heat the oven to 375 degrees. Spray a 12-cup muffin tin with vegetable oil spray.
2. Whisk 2 cups of the all-purpose flour, cake flour, 1/4 cup of the sugar, baking powder, baking soda, and salt together in a medium bowl. In a large bowl, beat 3/4 cup more sugar and butter together with an electric mixer on medium speed until light and fluffy, 3 to 6 minutes. Beat in the eggs, one at a time, until combined, about 30 seconds. Beat in the lemon juice, lemon zest, and vanilla until incorporated, scraping down the bowl and beaters as needed.
3. Reduce the mixer speed to low. Beat in one-third of the flour mixture and half of the yogurt. Repeat with half of the remaining flour mixture and the remaining yogurt. Beat in the remaining flour mixture until just incorporated. Do not overmix.
4. Toss the blueberries with the remaining tablespoon of all-purpose flour, then gently fold them into the batter with a rubber spatula. Using a 1/3-cup measuring cup sprayed with vegetable oil spray, portion the batter into each muffin cup, then portion any remaining batter evenly among the cups using a small spoon (My cups were almost completely full). Sprinkle the tops with the remaining tablespoon sugar. Bake until golden and a toothpick inserted in the center of a muffin comes out with just a few crumbs attached, 25 to 30 minutes, rotating the pan halfway through baking.
This recipe made 12 regular and 24 mini. Exactly. :)
