Sprinkle gelatin over 1/4 cup water to proof. Do this in a mixing bowl.
While it proofs, heat sugar, agave syrup, and water over stove. Allow to come to 240° without stirring.
Once the sugar reaches 240° pour it over the gelatin and beat at high speed for 5 minutes. Stop and add vanilla then, beat for a few more minutes.
Stir in melted butter.
Fold in rice krispies and sprinkles.
Press into a pan and wait for about 10 minutes then cut and serve.
