Rich, fudgy chocolate brownies with a shiny crackly top, made fiber-rich with bloomed flaxseed and psyllium husk instead of the usual bean purée.
Bloom the flax and psyllium fully — a rushed gel won"t trap enough moisture and you"ll end up with a dry, crumbly bake. Store airtight at room temperature up to 4 days, or freeze the sliced squares up to 3 months. For dairy-free, swap the butter for melted coconut oil at the same weight. Chia seed can replace flax; bloom it the same way.
