Pour all crepe ingredients (excluding oil) into blender. Blend for 10 seconds. Scrape sides of blender with spatula to ensure ingredients are combined. Refrigerate for 30 minutes.
Brush an 8” skillet lightly with cooking oil or melted butter. Heat over medium heat. Pour a bit less than ⅓ cup of batter into the pan, tilting the pan so the batter forms an 8” circle.
Remove to a cooling rack to cool and repeat until you have used all of your crepe batter. Note: You only need 20 crepes to make this crepe cake, you will have a few extras.
Place one crepe on a serving platter then portion a large spoonful (about 3 Tablespoons) of filling over the crepe. Use an offset spatula to spread evenly over the crepe.
Top with your next crepe, then repeat until you have used 20 crepes and all your filling (if you have any filling left over, feel free to use your extra crepes!)
Place chocolate in heatproof bowl. Place cream in a small saucepan and heat until steaming. Pour cream over chocolate, cover with foil, and let sit for 5 minutes.
Whisk chocolate until smooth. Let chocolate cool until slightly thickened, then spread evenly over crepe cake. Return to fridge and let chocolate set. Enjoy!
