Preheat oven to 375°F (190°C). Line a muffin tin with paper liners.
In a large bowl, whisk together flour, sugar, baking powder, and salt.
In another bowl, combine milk, vegetable oil, and vanilla extract. Add to the dry ingredients and mix until just combined.
Fold in chopped strawberries.
In a separate bowl, beat cream cheese, sugar, and vanilla extract until smooth.
Fill each muffin cup halfway with muffin batter. Add a spoonful of cheesecake filling, then top with more muffin batter.
Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
Let cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
