In a large bowl, beat the softened cream cheese and powdered sugar with a hand mixer for 2–3 minutes until smooth and fluffy.
Add the vanilla extract and mix until fully blended. Gently fold in the whipped topping with a spatula, keeping the texture light and airy.
Divide the filling evenly into 3–4 small bowls. Add a few drops of pastel food coloring to each and stir gently until the colors are uniform.
Spoon dollops of each colored filling into the graham cracker crust, alternating colors to create a patchwork. Use a toothpick or butter knife to gently swirl the colors together without overmixing.
Refrigerate the pie for at least 4 hours, or overnight, until fully set and firm to the touch.
Before serving, top with Easter sprinkles, candy eggs, or marshmallow bunnies. Slice into colorful servings.
