Creating this Fruity Pebbles Cheesecake is a fun and straightforward process. Just follow these steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C).
2. Prepare Crust: In a mixing bowl, combine crushed graham crackers, ½ cup of granulated sugar, and melted butter. Mix until combined.
3. Form Crust: Press the graham cracker mixture into the bottom of a 9-inch springform pan to create an even layer. Bake for 10 minutes, then remove from the oven and let cool.
4. Beat Cream Cheese: In a large bowl, beat 2 cups of softened cream cheese until smooth and creamy.
5. Add Sugar and Vanilla: Gradually add 1 cup of granulated sugar and 1 teaspoon of vanilla extract to the cream cheese. Mix until well combined.
6. Incorporate Eggs: Add the eggs one at a time, mixing just until incorporated after each addition.
7. Add Sour Cream: Fold in 1 cup of sour cream until fully combined.
8. Fold in Fruity Pebbles: Gently incorporate 1 cup of Fruity Pebbles cereal into the cheesecake mixture.
9. Add to Pan: Pour the cheesecake mixture over the cooled crust in the springform pan, smoothing the top with a spatula.
10. Bake: Bake in the preheated oven for 55-60 minutes until the edges look set but the center is slightly jiggly.
11. Cool: Turn off the oven, crack the door open, and let the cheesecake cool for 1 hour inside. This will help prevent cracks.
12. Chill: After it has cooled to room temperature, refrigerate the cheesecake for at least 4 hours, or overnight for better texture.
13. Serve: Before serving, top with whipped cream and sprinkle additional Fruity Pebbles on top for decoration.
