Skinny Funfetti Cake is a lightened up dessert with lots of sprinkles and a magical frosting. So easy to make with a box of cake mix.
Preheat oven to 350 degrees. Spray a 9x13-inch baking dish with cooking spray. Set aside.
Using an electric mixer, beat cake mix, yogurt, and water until mixed well.
Pour batter into prepared pan. Spread batter evenly.
Bake 25 to 30 minutes, or until set in the middle.
In a large bowl, whisk together pudding mix, milk, and vanilla until smooth. Fold in whipped topping. Spread frosting on cooled cake. Sprinkle with sprinkles.
