Preheat oven to 325 F and prepare mini-muffin pan by lightly greasing (I misted with spray-canola oil).
Pour canola oil in a medium saucepan over very low heat. Add butter and chocolate. Stir occasionally over low heat until butter and chocolate have completely melted. (*Note: don't be impatient and crank the heat to make the chocolate melt faster: It is critical that the butter melts slowly and does not bubble or boil. .
Add sugars, milk, and Special Dark cocoa powder.
Stir until all ingredients are well combined.
Remove mixture from heat and allow it to cool for 5 minutes.
Stir in vanilla.
Add eggs and beat well, until mixture is smooth and oil does not separate.
Gradually stir in flour and salt. Stir well, until mixture is smooth and oil is not separating from the mixture.
Pour batter into prepared mini-muffin tray, filling cups about ¾ full.
Bake on 325 for 20 minutes.
Once brownie bites have finished baking, allow them to set for 3-5 minutes and then sprinkle with sea salt.
