Preheat the oven to 350 F. Line a baking sheet with parchment paper.

Heat treat the flour: spread Funfetti mix evenly on the baking sheet. Bake for 10 minutes (you can stir the flour gently halfway through), until it reaches an internal temperature of 160 F.

Add Funfetti mix, Cool Whip, and yogurt to a large bowl and stir until mixture is mixed well and smooth. Cover with plastic wrap and place in the fridge for at least 1 hour.

Fold in sprinkles gently (they will bleed if mixed too much), reserving some for the top of the dip. Add dippers of choice and serve.
