– Butterator

 Soft Butter is probably the most important item in Cookietology. Butterator's task is to create it.
The butterator needs a fan and some milk to operate. The fan is a block and is placed on top of the machine, while milk should be placed through buckets in its GUI.
Once everything is ready, the butterator will start to consume milk, while displaying different statuses on its display:

– Missing Fan

– Time Left

– Cooldown (when it creates the butter)

The butterator will output a random of Soft Butter, between 1 and 4.
The cooldown status also implies more things, but we'll talk about them in another block.

– Butterator Fan
It's the butterator second part, mandatory to work.
Once the butterator enters the cooldown stage, its fan has a 20% chance of breaking. To fix it, simply use an iron ingot on it.

– Mixing Bowl
Accepts 6 items, if they form a recipe then you can mix them.

To mix the ingredients crouch and right click the bowl several times until something pops out.

– Baker
Like a furnace, but with 2 ingredient slots!
Here you will bake a final Shaped Dough with cocoa beans, creating the cookie of your dreams. This cooking process may take a little longer than a normal furnace.

Alright, so you want to start making custom cookies.

The first thing you'll need is Soft Butter, the above page already explains how to make it, so I'll assume you already have some of them. After that create some flour on the crafting table, the recipe is easy (Make a 4×4 with wheat).
Grab a Mixing Bowl and place it on the ground, here we'll mix some ingredients to make the base dough:

As you can see doughs have stats: Brilliance and Thickness.

At the moment of baking, these two will define all the properties of our final cookies (Eat Speed, Saturation, and Nutrition).

The short explanation for the formulas:
More thickness means more nutrition but less saturation
More brilliance means more saturation but less nutrition
Eat speed is the absolute difference between the thickness and brilliance

Anyways, here is the cool math if you want to be precise:

So… How I Increase the brilliance and thickness of my doughs?
– To increase the brilliance mix again your dough with a Soft Butter, there is a 50% chance that the brilliance will be increased by one point. 
Max Brilliance value is 10.
– To increase the thickness put your dough with more doughs on a crafting table, these will fuse and the thickness points will be added. 
Max Thickness value is 50.
[!] If you mess something up you can always clean your dough by mixing it with flour in the bowl.

That's it, once you have the perfect dough create a Cookie Mold and use it with your dough. (Crafting Table)
At this step there is no turning back, a Cookie Shaped Dough is unmodifiable.

Everything ready, time to bake.
Grab your Cookie Shaped Dough and some cocoa beans, put them on a Baker and turn it on. Wait until cooked!
That's all, you have a round of 8 fresh cookies with the stats you want. Enjoy them and make any experiments you want.
