1 box (18.25 oz) yellow, vanilla or white cake mix, dry
1/4 cup butter, melted
40 Rolo Candies, unwrapped and cut in half
Preheat oven to 350°
Spray a 9x13 pan with cooking spray. With your mixer, beat cake mix, milk and butter until combined. Mixture will be thick and sticky. Divide batter in half and press 1 half into the bottom of the pan. Bake until just set, approximately 8-9 minutes.
Remove base from oven and place Rolo candies, caramel-side down on top.
Drop remaining batter on top of Rolos in teaspoon sized amounts.
Bake for 20-24 minutes longer until top begins to golden.
Cool completely before cutting into squares.
