Hark! Take heed, for this cake be both mighty and magnificent!

1.75 cups flour
2 cups white sugar
2 tsp. baking soda
1 tsp. baking powder
0.75 cups unsweetened cocoa powder
1 tsp. salt
2 eggs
1 cup (as in 8 fl.oz/250mL.) strongly brewed coffee (make more and drink it!)
1 cup buttermilk (or 1 tbs. white vinegar+1 cup milk mixed well, blah blah)
0.5 cups cocoanut oil (or 0.33 cups basicallywhatever oil), a little less if ***
1 tsp. vanilla extract
OPTIONAL:
2-3 shots (60-90mL; 0.2-0.33 cups) black spiced *** (Kraken, if at all possible)
I also want to experiment with whiskey/burbon.. if you try it, let me know!

--Flour, sugar cocoa powder, baking soda+powder, salt mixed in one bowl
-- eggs, coffee, ***, buttermilk, oil, vanilla in another

Slowly mix the dry into the wet until as homogenous as possible.
I use an 8"x8" (20cmx20cm) pan @350F (175 C) for about 40 minutes, but I check on it at round 30 minutes because some variance may well apply. If you use olive oil, or avocado oil, or whatever other more fluid oil, I find a slightly hotter oven (375 F/190 C) can be advisable, but pay attention to your specific scenario! The worst that's happened for me is the top gets a bit crusty, but that pleasantly works with the overall moisture of the cake, especially with olive oil and the *** addition.
Do the toothpick test to see if it's ready!

Frosting is applicable, as well, because this Magical Cake is not horribly sweet for how horribly sweet it sure is. I usually just sprinkle some confectioner's sugar on it to make it look all fancy for my classy friends and band-mates.
ENJOY!
Bake responsibly, but have some fun.
Also, suffer the decimals!
