I'm going to double the recipe and I will report back.
The next morning...
These were good! I really liked them. A couple people did not love the texture of having shredded coconut in the waffles, but I did and a couple others did too.
I did not double the recipe as I only had one can of coconut milk in my pantry. There were plenty to feed this family of six (may have made 20 waffles - 5 rounds of 4 in the waffle iron).
When I opened up my can of coconut milk, it was a beautiful thick creamy texture usually highly coveted. But this meant there wasn't much actual liquid in the can so I ended up adding almost a cup of milk (cow's) to get it the right consistency.
I used butter as the recipe called for but you could definitely use melted coconut oil; I'm all out.
These were sweet and crispy in the "wells" of the waffle. I had to let my waffle iron go past the first warning beep that they were cooked to the second warning so they wouldn't be wet inside. Go with your gut and watch the steam and when the steam stops pouring out, they're done.
