Melt organic cane sugar over medium heat until deep amber. Immediately pour into a flan or bundt pan, tilting to coat the bottom evenly.
Combine dry ingredients (flour, sugar, cocoa powder, baking soda, salt) then add in wet ingredients (oil, milk, espresso, egg, vanilla). Whisk until smooth. Gently pour over the caramel layer.
Blend eggs, condensed milk, evaporated milk, espresso, and vanilla until smooth. Do not over blend. Slowly pour over the cake batter.
Cover tightly with foil. Place pan in a water bath. Bake at 350°F for 60-70 minutes, until set with a slight jiggle in the center.
Cool completely, then refrigerate overnight. Invert onto a serving plate.
Cover the top layer with thin dark chocolate strips before serving.
