Preheat oven to 350 degrees F (176 C) and lightly spray 2 8-inch round cake pans or 1 large rectangular pan with nonstick spray (see notes for cooking times for different size pans // adjust number or size of pans if altering batch size). Dust with cocoa powder, shake out the excess and set aside.
Mix the almond milk and vinegar in a large mixing bowl, and let set for a few minutes to activate. Add the oil, coffee, vanilla extract, and applesauce and beat until foamy. If coconut oil hardens, microwave the mixture in 10-15 second increments until melted.
Divide batter evenly between your cake pans or rectangular pan.
*I tested butternut squash puree in the original recipe and it made it a bit too dense for my liking. Applesauce was perfect, which is why I highly recommend it over other purees.
*Double the recipe and use 4 pans for a 4-layer cake. Halve the recipe and use 1 pan for a 1-layer cake.
