1. Preheat oven to 350 degrees F, and spray an 8x8x2" square baking dish with cooking spray. Thoroughly mix the flour, sugar, baking soda, and salt in a bowl. Create a well in the center, and add 1 cup nondairy milk, oil, vanilla, and vinegar in the center. Gently mix until homogeneous (do not over mix).
2. Pour the batter into the pan a bake for 30-35 minutes. Allow to cool for an hour. After cooling, use the end of a spoon or something with a bit of girth, and stab the cake to create holes or wells for the milk to soak into later.
3. For the milk, with a spoon, gently remove the heavy fat/cream from the coconut milk can being careful not to include the non fatty and more watery coconut milk. Place the fatty cream in a bowl in which you can whip it. Set the bowl of cream in the fridge to whip later.
4. Measure out 1 cup of the leftover coconut milk. Mix it with 1/2 cup nondairy milk and sugar. Pour this into the cooled cake that has been prepped with wells to soak up the milk. Be sure to turn the pan or use your spoon to ensure that enough milk falls into all of the wells. This will ensure a true tres leches moistness.
5. Remove the coconut fat from the fridge. Whip it with a whisk to your desired consistency. Pour over the top of the cake once most of the milk has absorbed.
Enjoy the best tres leches you've ever had; yes, it's better than the original (I think so at least)!
