Sounds delicious and would love to try it but am disappointed that this is NOT a dump cake

Sorry that should have read picture NOT picturembier. Also cake cuts into squares just fine

I made this cake this morning and it turned out perfectly, just like the picturemblier. It is moist and not any more crumblier than any other cake

I agree with other poster - this is very crumbly. I was expecting a more bar like cake. There is no way you can cut these into squares as they won't hold together. It tastes good, but you really don't taste any root beer flavor.

Texture was a little disappointing as it crumbles. Guess this is true of all dump cakes, even though this is technically NOT a dump cake Followed directions, cake was delicious BUT you definitely need to eat it with a spoon as it crumbles, even though it is moist. All my chips sunk to the bottom of the cake, not like in the picture where they are evenly distributed throughout.

If you "dust" the chips with flour, it will keep them from sinking to the bottom.

It's not as moist as I would've liked it, but it is still good. Has anyone figured out the nutrition info for it, even an approximate one?

Do you have to put the coconut on it if you don't like coconut?

Why would you ask this question? You know you don't.


ANY recipe is a basic guide. If you don't like an ingredient, leave it out or change it

Is this a dry or moist cake? I simply love very moist cake. Chips tend to dry out and remain hard after a few days. I cannot consume all of this cake at one time. Will try it anyway.

Crap! I don't like Root Beer and it looks so good!

I agree with mrgerie 2645418, you don't beat a Dump Cake, but the beaten kind is OK too.

This is excellent. And it's definitely a dump cake, lol. You dump ingredients, stir together, spread in pan, bake. I went exactly by directions and it was a HUGE hit with picky cake eaters. I will continue to make. Thx so much for posting.

Yes, u do have to "beat' it.. I did it with a big fork, not mixer.

Sorry, but this is NOT a dump cake!


Why can't diet soda be used? What difference would it make?

Hello. If you prefer you can definitely use diet soda instead of regular. We just preferred to use regular soda when developing this recipe in the Test Kitchen. Enjoy!

I would like to make this for a fellowship luncheon for Church this Sunday. Do you think I would be able to double the recipe and bake in 1 pan or should I just make 2 seperate cakes?

Hi there! - We definitely recommend baking in 2 pans if you plan on doubling this recipe.

if you double the recipe why not use a larger pan?

A 9- x 13-inch pan is a typical cake pan. We're not sure what size a larger pan would be, but if this cake is baked in a dish that's is not twice the size of a 9- x 13-inch dish, then it will be hard on the outside and not cooked on the inside. So, we recommend using 2 9- x 13-inch dishes to double the recipe. Hope that provides some clarification!
