Heat up water, make sure not to boil it. Then, add the hot water to a small bowl. Add the gelatin to the water and stir until the powder has completely dissolved. Set aside.
Spoon the sour cream into a large saucepan and stir in the sugar. Cook the ingredients over medium heat, until the mixture is about ready to come to a boil. Continue stirring the sugar into the sour cream until it’s completely dissolved.
Remove the pan from the heat and stir in the gelatin until it’s fully mixed into the sour cream-sugar mixture.
Next, add the yogurt to the pan and continue stirring until all the ingredients are well blended.
Spray the mold with nonstick cooking spray and pour the yogurt mixture into the pan. Spread the yogurt evenly over the pan, then allow it to rest until the mixture reaches room temperature.
Then transfer the mold to the refrigerator to chill for at least 3 hours or until jello is firm.
The Jello is ready to serve when the mixture is solid and your finger bounces back when lightly pressed into it.
