French Coffee Custard

I'm the guy who needs coffee to function, so a French Coffee Custard in the Ninja Creami was basically inevitable. It tastes like a frozen latte that grew up, smooth and a little grown-up bitter from the espresso powder, not that fake coffee-candy flavor. My wife stole the first scoop and declared it dessert and breakfast, which I respect. Dissolve the instant espresso in the warm base so you don't bite into gritty specks later. First spin looks crumbly every single time, so add a splash of milk and re-spin until it turns creamy.
