Ingredients
Method
- Preheat the oven to 425°F (220°C). Line a 12-cup muffin pan with paper liners and prepare extra liners for the remaining batter.
- Beat the cream cheese, sugar, and vanilla until smooth. Set aside.
- In a large bowl, whisk together the oil, melted butter, and sugar. Add the egg, egg white, buttermilk, and vanilla, then whisk until smooth.
- In another bowl, whisk together the flour, cornstarch, baking powder, and salt. Fold the dry ingredients into the wet ingredients just until combined.
- Toss the blueberries with a teaspoon of flour, then gently fold them into the batter.
- Mix the streusel ingredients together until crumbly.
- Fill each muffin liner one-third full with batter. Add about 1 teaspoon of cheesecake filling, cover with more batter until three-quarters full, then sprinkle with streusel.
- Bake for 5 minutes at 425°F (220°C). Without opening the oven door, reduce the temperature to 350°F (175°C) and bake for 18–20 minutes, or until a toothpick inserted near the edge comes out clean.
- Cool the muffins in the pan for 10 minutes before transferring them to a wire rack to cool completely.
