16 - 7 oz chopped dark chocolate (70%)
17 - 7 oz chopped milk chocolate

→ Ganache

24 - 6 oz dark chocolate chunks (70%)
25 - 3/4 cup (180g) whipping cream

# Preparation Steps:

01 - Combine dry stuff in one bowl, wet stuff in another, then mix them together and bake in your springform pan at 350°F until done, about 25-30 minutes
02 - Cut off any dome from the cooled cake, wrap the inside of pan with acetate or parchment paper. Drizzle your coffee-cocoa mix all over the cake
03 - Melt both chocolates together, stir in egg yolks. Mix in your cream and gelatin blend. Gently fold in the whipped cream followed by your meringue mixture
04 - Dump the mousse on top of your soaked cake and let it firm up in the fridge for at least 4 hours but better overnight
05 - Whip up the ganache and pour it over your set mousse. Stick it back in the fridge for half an hour before you dig in

# Additional Tips:

01 - Swap in gluten-free flour if you want
02 - Don't have acetate? Just use parchment paper instead
03 - Tastes way better when it sits in the fridge overnight
