In a medium mixing bowl, combine cake mix with greek yogurt, and water. Whisk together until smooth.
Spray mini muffin pan or line with cupcake liners and divide batter evenly among 48 cupcakes (roughly a heaping tablespoon in each).
Bake for 14-16 minutes, until a toothpick comes out clean. Let cool before frosting.
Cream Cheese Frosting
In the bowl of a stand mixer, combine cream cheese and butter and beat on medium speed until well combined and fluffy. Add powdered sugar and powdered sugar substitute 1/2 cup at a time until frosting thickens. Add vanilla and beat on medium speed to combine, until frosting is fluffy.
Frost each mini cupcake and finish with some sprinkles. Keep in the fridge until ready to eat. Enjoy!
