Add powdered sugar. Mix until combined
Add sour cream, heavy cream and vanilla extract. Mix until thick and creamy (about 5 minutes)
Divide filling evenly into two separate bowls.
Add about 5 tablespoons of purée to one bowl. Mix until combined. (If you want a brighter pink color, you can also add a few drops of pink food coloring).
Pour half of the white filling into the pan. Spread evenly over the crust.
Add a few spoonfuls of raspberry purée on top of the filling. Add the other half of the white filling and spread evenly with an offset spatula.
Add more purée and pour half of the pink raspberry filling into the pan. Spread evenly with an offset spatula.
