Preheat oven to 350°F (180°C).

In a large mixing bowl, beat softened cream cheese with an electric mixer until smooth and creamy.

Gradually add powdered sugar, beating until fully combined and the mixture is smooth and lump-free.

Stir in vanilla extract until thoroughly incorporated.

Pour the cream cheese filling into the pre-made graham cracker crust, spreading evenly.

If creating a color swirl, separate the cream cheese filling into 4-5 small bowls.

Use gel food coloring (pastel shades work beautifully for Easter) to tint each portion of batter. Stir each bowl well to achieve even colors.

Spoon dollops of each colored filling randomly over the plain cheesecake batter already in the crust.

Using a toothpick or skewer, gently swirl the colors together, moving in a figure-eight or circular motion to create a marbled effect.

If desired, you can also sprinkle pastel-colored M&M's or Easter-themed candies on top before baking for added decoration.

Bake the pie for 40-45 minutes, or until the center is just set and the edges are slightly golden. The center may still have a slight jiggle.

Allow the pie to cool completely at room temperature on a wire rack. Then, chill in the refrigerator for at least 4 hours (preferably overnight) before serving for the best texture and firmness.
