Step 1

Preheat the oven to 350 degrees and line a 9 x 13 baking dish with parchment paper or foil. Lightly spray with non-stick spray and set aside.

Step 2

In a large bowl, cream together the butter and cream cheese.

Step 3

Add in the egg and vanilla and mix until fully combined.

Step 4

Add in the Funfetti cake mix, 1/3 at a time, and mix until combined. The batter will be very thick.

Step 5

Feel free to add additional sprinkles to the batter -  also stirred in the sprinkles that came on the top of the Funfetti frosting can.

Step 6

Spread evenly into the prepared baking dish and bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.

Step 7

Once fully cooled, frost, add sprinkles, and cut into bars.
