What is the glaze on top in the last picture?
Hi Andrew ~ what looks like a glaze is actually just the key lime pie filling peeking through. 🙂
Would this work with a yellow cake mix instead?
Hi Kennedy ~ yes… you could substitute a yellow cake mix. Enjoy! 🙂
for a old 69 yr old vet these are great………..you can fill them with darn near anything, fresh and from a can. I am disabled and this is so much easier then the long drawn out way to make a cake……………thank you…
Aww ~ you’re very welcome! Dump cakes are definitely some of my favorite desserts, too! So easy and so many flavor combinations! 🙂
How do you serve the cake? Do you turn it out on a plate and cut it or do you spoon it out like you would a cobbler? Thanks!
Hi Cathy ~ you’ll just spoon it out with a large spoon… just like a cobbler. 🙂
Thank you! I can’t wait to try this! 🙂
Do you prepare the cake mix according to the box? or just the dry mix and butter?
Hi Mae ~ no… you’ll just use the dry mix and butter. Hope that helps!
I never knew you could buy key lime pie filling. We like the yogurt, so we’d probably like this too. Thanks for sharing.
You’re very welcome, Brenda! You’ll find it on the baking aisle near the other pie fillings. It is SO delicious… just like the yogurt. 😉 ENJOY!
