Easy to make sprinkle Confetti Cake Batter Brownies recipe. These funfetti brownies are moist and so ooey gooey good!
Spray a 11x9 baking pan with nonstick spray.
Combine cake mix, vegetable oil, egg, and milk into a bowl. Mix with hand mixer.
Add sprinkles and white chocolate chips, continue to mix until all combined.
Spoon batter from bowl into baking pan, sprinkle a few more rainbow sprinkles on top.
Bake 25-30 minutes until your edges are slightly brown. Mine take 26 minutes to be exact.
Since the brownies are very fudgy, please allow them to cool completely or they will fall apart! :) After cooling, cut into brownie square and enjoy!
