Funfetti Gooey Butter Cake is a delicious and easy dessert everyone will love! The bottom layer is a butter cake and the top is a funfetti cream cheese layer that stays nice and gooey, almost cheesecake-like.

Preheat oven to 350F. Spray a 9x13-inch pan with nonstick baking spray. Set aside.
To make the cake, beat together cake mix and egg whites with an electric mixer until smooth.
Add melted butter and beat until just combined.
Spread the batter into the prepared pan. (It will be thick and hard to spread but you want it to reach all the corners and sides. I found that an icing spatula really helped to smooth it out.) Set aside.
To make the gooey filling, beat together cream cheese and vanilla with an electric mixer until smooth. Add egg whites and beat again until smooth. Add the melted and cooled butter; beat until smooth.
With the mixer on low, slowly add the powdered sugar and beat until the powdered sugar is incorporated and mixture is smooth.
Use a rubber spatula to fold in sprinkles.
Spread the filling over the cake batter.
Bake for 40 - 45 minutes, until the center is set and the edges are puffed up and golden brown.
Let cool before slicing and serving.
Serve with ice cream and sprinkles on top.
