Place butter in a small sauce pan and heat on low until melted. Set aside.
In a mixing bowl, whisk together all the dry ingredients (sugar, cocoa powder, sea salt, all-purpose flour and baking powder). Make a well and add the eggs. Gently start mixing inwards going outwards with your mini whisk. Add the cooled melted butter and vanilla extract. Mix until it is all incorporated.
Scoop your preparation into the Flexipan®, flatten the batter if necessary with your spatula.
BAKE!
Bake for 20 minutes at 350F/180C. (Every oven heats differently, monitor your brownie from 18min). Always remember to undercook your Brownie, it tastes so much better this way!
Once your brownies are out of the oven, let them cool down for at least 30 minutes. Then, Unmold and set aside.
CHOCOLATE GANACHE
While your Cake is cooling down, prepare the Chocolate Ganache.
Pour the heavy whipping cream into the Mini Round Mold and bring it just to a boil in microwave, about 30 seconds at a time. Add the dark chocolate chips and swirl to coat all chips. Allow to sit for 2 minutes, then stir. Pour into each savarin's well, sprinkle powdered sugar, cinnamon and cocoa on top. Enjoy at room temperature & Bon Appétit.
