  1. Hi Lori,
    Yes, I have made this in a 9 x 13 pan and it works. If you use cool whip don’t add regular root beer. You could add a few drops of root beer flavored extract. -Amy

  2. If you use Cool Whip, how much root beer would you add? Don’t want it too runny?!?

  3. Did anyone try the recipe with a 9×13 pan?

  4. Hi Joan. I use Dream Whip. It’s the dry packet of whip topping. Comes in a box. Also cold root beer. I’ve been this many times and it whips up perfectly. -Amy

  5. Just the Whip It and root beer are suppose to make a frosting??? After 5 minutes on high I still had liquid.

  6. I loved this idea, I think I’m going to make these for my graduation party. And for my welcome home party when I return for my military training:)

    They were so easy to make and tasted great. I used a piping bag to ice so I took your tip to double the recipe but I had a lot leftover. So I froze it and am gonna use it over root beer for kinda a real root beer float. Thank you so much.

  8. Delicious is right!!!! Fun, cool, light cup cakes and toppings yumm. My only concern is the topping was very expensive 2 pck of dream whip was $2.58 at Walmart. That could be $5.00 to $10.00 if u double the topping . No complaints. We tried an alternative bought the ready made Topping added some root beer and melted the candy added powdered sugar used a press with different top designs. Did this last night the topping is still holding up Amazing.
    Saw u on channel 6 new Milwaukee a week a go or so.
    Luv it.

  9. Great recipe! Super easy to make. Did have about double what I needed to frost them though…

    1. Hi Lori,

      I’ve added a note to the recipe to double the frosting when using a piping bag. Thanks for sharing that tip!


  10. I saw you on WKYC last week and can’t wait to make these. Since the frosting is made with Dream Whip can I make them the night before and do they need to be refrigerated? I was concerned about the frosting holding up. Thank you!

  11. just made them they are good and fluffy and they are so easy to make

    Very moist tender cake and you can really taste the root beer in the icing.They were nice and light not too sweet or rich.Made them a birthday party and they went over well.They looked very cute as well.

  13. Oh my gosh! Fabulous! Saw “The Cooking Mom” on WGN Chicago mid-day news last week and immediately went to store to buy ingredients and made them yesterday! You rock!
