Bakery Style Lemon Blueberry Muffins

Ingredients

• 2 1/2 cups all-purpose flour
• 1 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt
• 1 cup granulated sugar
• 1 – 2 Tbsp lemon zest
• 4 Tbsp butter, softened
• 4 Tbsp vegetable oil, divided
• 2 large eggs
• 1/2 cup buttermilk
• 1/2 cup sour cream
• 3 Tbsp fresh lemon juice
• 1 2/3 cups fresh blueberries
• Topping:
• 1 1/2 Tbsp sparkling sugar/raw sugar

Directions

1. Heat the oven to 425 degrees. Set paper liners into a 12-cup muffin pan.
2. In a mixing bowl, whisk the flour, baking powder, baking soda, and salt for 20 seconds, then put the bowl aside.
3. Pour the sugar into the bowl of an electric stand mixer. Add the lemon zest and beat with the paddle attachment for 15 seconds.
4. Add the butter and 1 Tbsp vegetable oil, then beat until the mixture looks light and fluffy. Beat in the remaining 3 Tbsp vegetable oil.
5. Add the eggs, mixing them in one at a time. Take the bowl off the stand mixer.
6. In a separate bowl or liquid measuring cup, whisk the buttermilk, sour cream, and lemon juice together.
7. Add 1/3 of the flour mixture to the butter mixture and fold just until it is almost incorporated. Add 1/2 of the buttermilk mixture and fold again until nearly mixed in. Repeat with another addition of the flour mixture and the remaining buttermilk mixture. Fold in the last 1/3 of the flour mixture until it is just about combined.
8. Fold in the blueberries. By now the batter should be fully mixed, but do not overdo it; it will be thick and beginning to puff up.
9. Spoon the batter into the lined muffin cups, mounding each one generously full, about a slightly heaped 1/3 cup per cup. Use all the batter. If using sanding sugar, scatter it evenly over the muffin tops.
10. Bake for 8 minutes in the heated oven, then lower the oven temperature to 400 degrees. Continue baking for 10 – 13 minutes more, until a toothpick poked into the center comes out without wet batter.
11. Take the muffins out of the pan and let them cool on a wire rack. Store the muffins in an airtight container.
