Mix the oatmeal, water, and dairy product of choice together well and cover. Let set for 24 hours.
If it’s very wet you can strain it a bit if needed, then spread onto two parchment paper-lined baking pans. Place in 170* oven, or lower if your oven goes lower, and leave it for a couple hours, turning over once. If you stay close by you can turn this temp up a little higher to make it go a little faster. At this point it wasn't dried enough (you just want it so you can break the pieces up a little for the next step), but it was bedtime, so I turned the oven off and left it there overnight with the oven light on, not wanting to ruin another batch... Melt the coconut oil, sugar, maple syrup, and sea salt together in a medium saucepan.
Next, break up the oat pieces into a big bowl (keep the parchment paper on the baking pans to reuse again in a sec) and add dried fruit, nuts, einkorn flour, and the melted mixture from above. Stir well.
Spread it out onto the pans again and place them back into a 170* oven. I left it for about 6 more hours. Keep checking it until it gets to the desired crispiness. Other times when I've made it, it takes much longer for some reason, so I get impatient and turn the heat up higher again to 350* and watch it closely, it may take another 2-3 hours until it's crispy enough, but not so hard that it hurts your teeth! Your oven temp may heat differently than mine so you'll have to keep checking it. Just remember that it will crisp up a little more as it cools.
So again, this isn't tricky at all, but keeping such a close eye on it is a little annoying.
