If you are not super comfortable working with mousse and ganache, do yourself a favor & pour the top layer of ganache on the cake while still in the springform pan. Pop it back in the fridge for 5 mins. Then take it out & run a knife around the edge & separate it from the springform pan & use a spatula to apply ganache to the sides of the cake.
If the weight on top is too heavy, the white chocolate mousse layer will “melt” when you try and spread the ganache down the sides.
Eli
Will this work with a 10in springform pan?
Mindee
Yes, as long as you bake the cake layer in a 10 in cake pan instead of a 9 inch one. Otherwise you'll have an 1 wide gap between the cake layer and the edges of the springform pan.
Jeannette Navas
Are the ingredients for the first layer right? It seems there is not enough liquid for the dry ingredients. It was not a normal cake consistency but more for like brownies or harder.
★★★
Mindee
Yes, the ingredients are correct but no the batter should not be that thick. It's thicker until the boiling water is added. Did you add the boiling water?
Kristen Hale
Mindee, Thank you so much for making this cake and sharing it with me for teacher appreciation! It is so, so, so delicious. Seriously one of the best slices of cake I have ever eaten. You are awesome!
★★★★★
Mindee
Thank you!!! I truly appreciate all your hard work and kindness this school year!
Hannah
Hi, I was looking to make this for the holidays, but I don't have a springform pan, would there be a substitute for this, or am I just out of luck?
Mindee
I really can't think of another pan that would be deep enough. The reason for the springform pan is because of the depth of it and the removable outside ring so you can add the ganache and chocolate chips to the sides, show off the dessert, and for easier cutting and serving.
Brittney
I'm having issues getting my whipped cream to peak for the chocolate layer with the gelatin mix. Help?
Mindee
Hmmm...ok, let's troubleshoot this. Were you using actual heavy cream? Meaning not organic cream or another substitution? Was your cream cold? Was the bowl you were whipping it in usually warm? How close to expiration date was the cream? Was it an off brand? Is it possible it was over beaten? Did you stop beating many times while beating to check to see how close to stiff peaks it was?
Rose
I made this cake for the birthday dinner of my boyfriend's father. Everyone loved it and it looked and tasted so decadent. I absolutely loved the balanced flavor, not too sugary although very chocolatey.

Cindy
How can i tell if ive over folded the cream into the white chocolate? It almost looks curdled to me but it was folded throughly. I hope it doesnt affect the taste!
mindeescookingobsession
Even if you over folded these ingredients it would still be smooth. Heavier, but smooth. It's more likely the whipped cream was over beaten. When you over beat whipped cream it starts to separate and look curdled.
Shauna
Can I just bake the bottom cake layer in spring pan?
Mindee
You can if you have a springform pan you trust not to leak in your oven. Even though I know my springform doesn't leak I am so paranoid that for some reason it will and I don't want to deal with that mess which is why I bake the cake part in a cake and transfer it.
