Heat oven to 350f. Take the flax seeds and put into a small bowl and add 6 T water, let sit for 2 minutes to thicken. In a spice grinder (or coffee grinder if you can clean it easy) take the nuts and grind them until it looks like mini tapioca beads, not super fine coarse flour meal. As you go pour all into a large mixing bowl.
In bowl add all the remaining ingredients as they are listed above (there's some mashing and chopping) then mix until combined. The mix will be thick like a cookie dough vs a light cake- these actually keep you full :)
Line the muffin cups with paper and scoop 1 massive tablespoon (a little less than 1/4 cup) into each, then top off the smaller ones with the remains until they appear to be even- do your best, this recipe is forgiving.
Bake 30 min, insert a toothpick, it should come out clean. If it doesn't cook for another 5-7 and test again. When ready let sit and cool to room temperature, top with room temperature butter and a sprinkle of spice on top. If you can't wait till then dig in, melted butter works too!
