Priscilla says
Could ylu make the cake in a square cake pan?
Julie Evink says
It would need to be split into two smaller 8×8 inch pans I think or it would be to much for a square pan.
Robin says

Awesome to hear Robin!
Deb says
I had family over today and made this cake. I am a hit or miss cook, but this was a HUGE hit! Everyone loved it, from my husband to my grown kids (which are picky) and my grandkids. I made it exactly as the recipe was written. I made it the night before, flipped it (I put parchment paper on bottom of cake pan and it came out great). It was beautiful. I used 2 long grilling spatulas to put back in cake pan after I flipped it and put in fridge overnight. I spread a whole container of sugar free cool whip on top this morning, then let it sit out a couple hours in covered cakepan. My 5 yo grandson begged to take some home. I had to divide the rest of the cake between the households and send home. I am one happy lady! Thank you for such a great recipe. I will definitely be making this again.
Julie Evink says
Now this is a win!! So glad you enjoyed it!
Marissa says
I want to bake this cake without the marshmallow layer. Have you tried it before and if not do you think it would effect the end result detrimentaly?
Linda says
I can I use frozen strawberries
Lynn says
MY Cake came out all runny what did I do wrong. Did I put to many strawberries in it.
Julie Evink says
Unfortunately I’m not sure what happened since I wasn’t there with you. Did you measure all the amounts according to the recipe?
