Making the 4th of July Swirl Pie is a straightforward process if you follow these steps:

1. Prepare the Pie Crust: Preheat the oven to 350°F (175°C). Place the pie crust in a pie dish and bake according to package instructions, usually about 10-12 minutes. Allow it to cool completely.
2. Mix Cream Cheese Filling: In a large bowl, combine the softened cream cheese, powdered sugar, and vanilla extract. Beat until smooth and creamy.
3. Add Whipped Cream: Gently fold in the whipped cream until well incorporated, ensuring a light and fluffy texture.
4. Divide the Mixture: Split the cream cheese mixture into three separate bowls.
5. Color the Mixtures: In the first bowl, add the strawberry puree and a drop of red food coloring if desired. In the second bowl, add the blueberry puree and a drop of blue food coloring. Leave the third bowl plain (white).
6. Layer the Mixtures: Begin layering the mixtures in the cooled pie crust. Start with a layer of the white mixture, followed by spoonfuls of the red and blue mixtures. Continue layering until all mixtures are used.
7. Swirl the Mixtures: Use a knife or skewer to gently swirl the mixtures together, creating a marbled effect. Be careful not to overmix; you want to maintain distinct colors.
8. Chill the Pie: Cover the pie with plastic wrap and refrigerate for at least 2 hours to allow it to set.
9. Serve: Once set, remove from the fridge and slice to serve.
