Instructions
To make the cakes:
Preheat oven to 350°F. Butter and flour a muffin pan or line with paper liners.
In a bowl, whisk together the coffee and cocoa powder until no lumps remain. Set aside. In another bowl, sift together the flour, salt, and baking soda.
In a large bowl, beat the sugar and eggs together until smooth and pale yellow in color. Stir in the sour cream, followed by the vegetable oil. Add the flour mixture all at once and stir until combined. Stir in the cocoa mixture and mix until smooth.
Fill each cup in the muffin pan ⅔ full and bake until a toothpick inserted into the center comes out clean, about 15-20 minutes. Let cool in the pan for 5 minutes, then remove and place on a wire rack to cool completely.
To make the icing:
Melt the white chocolate in a double boiler or in a heat proof bowl places over a pan of simmering water. Stir until smooth and remove from heat when melted. Slowly whisk in the sweetened condensed milk and espresso. The white chocolate will seize as you first stir them in, but don't be alarmed, keep stirring and it will become smooth.
Dip the tops of the cooled cakes into the warm glaze and set over a wire rack to cool, letting the glaze drip down the sides. Glaze will remain moist as it sits.
