Preheat oven to 400 F.
Grease four 6-oz ramekins with cooking spray and dust with cocoa powder.
Activate vinegar and almond milk by mixing together in a small bowl.
In a large bowl mix applesauce, vinegar-almond milk mixture, sugar, coconut oil, and vanilla extract until smooth.
Add flour, cocoa powder, baking powder, and salt to mixture.
Fold in melted chocolate.
Pour mixture into prepared pans.
Top with nut/seed butter and use a spoon to slightly press it down into the batter. Some may still be exposed.
Place ramekins onto a baking sheet and bake for 12-13 minutes until the sides appear solid and firm. The top may still look slightly soft. Allow to cool for 1 minute, then cover each with an inverted plate and turn over. Use an oven mitt because those ramekins are hot! The cakes should release easily from the ramekin.
