Chocolate Slab Cake

I bake healthy snacks for my kids through the week, but occasionally I do like to treat them to something ooey, gooey and utterly yummy as a Friday after school treat.

I found this Chocolate Cake with Cream Cheese Icing in the thermomix recipe community. I’ve never tried Chocolate Cream Cheese icing before and must say, this was so good I will definitely be making it again.

Here is a very similar regular version for you from Good Chef, Bad Chef.

{The Organsied Housewife} Chocolate Cake with Chocolate Cream Cheese Icing

I found the recipe on the community page hard to understand, I read their instructions to add all ingredients, not reading further enough for EXCEPT boiling water, so I have re-typed it out here, plus I also don’t cook it for as long as it recommended.  recipe credit to pkwilly.

Hi Katrina, is the icing very runny?

Can you freeze the cake with the icing on?

Hi there, I was wondering if it was possible to leave out the cocoa and if i needed to add anything extra to make it a plain vanilla cake. Thank you
