Welcome to the Cake Decorators Q&A

Can anyone please tell me how much trex to put into the buttercream just for structure as the video does not tell you. I don’t want the taste changing too much. Thank you

Hi Suisie Q

I don’t know how much shortening Paul uses however you will find a recipe in the rustic wedding cake tutorial by Mish here:

Click the ingredients tab to see the recipe.
Hope this helps.
