I tried the Deliciously Ella Fudgy Chocolate Brownie yesterday as it was £2 on offer in Tesco.
It's a 3/10. The main ingredient is coconut sugar which isn't really any healthier than normal sugar, why didn't they use dates to get all that fibre in? The chia seeds haven't been ground up so has that funny texture, you're supposed to grind them to make a vegan egg replacement for cakes.
Taste was ok, but had unhealthy ingredients like sunflower oil. I've made far better brownies from just blending oats, dates, cocoa, vanilla and chia seeds for 90% cheaper.
