Preheat your oven to 350°F (175°C).
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
Add the softened butter and mix until crumbly.
In a separate bowl, beat the egg and add it to the flour mixture, combining until dough forms.
Roll out the dough on a floured surface into a rectangle.
In a medium bowl, mix the cream cheese, powdered sugar, strawberries, and vanilla extract until smooth.
Spread the cream cheese mixture evenly over the rolled-out dough.
Starting from one end, carefully roll the dough into a tight log.
Slice the rolled dough into equal pieces, around 1 inch thick.
Place the rolls on a baking sheet lined with parchment paper.
Bake for 20-25 minutes or until golden brown.
Let the rolls cool slightly before serving.
