Need advice * sweets trigger warning*

Hi everyone! I’ve been doing really well on my lifestyle change and have lost 20 lbs. I struggle with sweet addiction so I’ve been avoiding them. The only thing I’ve really had is a fiber one brownie and it was good but not great. Long story short I’m going to a party tomorrow and there will be cake. Is there a better alternative that could satisfy a cake craving that I could bring with me?

I looked on Publix’s website to get nutrition info and it isn’t listed which scares me calorie wise. Help I’m having major anxiety! Thanks in advance Christine
