Method
 

Preparation
  1. Preheat the oven to 355°F (approximately 180°C) and line an 8x4 inch loaf pan with parchment paper.
  2. In a stand mixer, cream together the butter, sugar, and instant coffee until light and fluffy, about 3-5 minutes.
  3. Add the vanilla, eggs, and egg yolk one at a time, mixing well after each addition.
  4. Slowly incorporate the flour, cocoa powder, and baking powder, mixing on low speed until just combined.
  5. Pour the batter into the prepared baking pan, smoothing the top with a spatula.
Baking
  1. Bake in the preheated oven for 40-45 minutes or until a wooden skewer inserted into the center comes out clean.
  2. Remove from the oven, allow to cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely.
Making the Frosting
  1. Dissolve 1 1/2 teaspoons of instant coffee in 1/2 teaspoon of hot water and let it bloom for a minute.
  2. Beat the stick of butter until creamy, then gradually add the sweetened condensed milk and the dissolved coffee. Whip until smooth and glossy.
  3. Spread the frosting evenly over the cooled loaf. Let it set a little before slicing.

Notes

For a thicker slice, serve with a steaming mug of black coffee or milky tea. Store in an airtight container for up to 2 days at room temperature, or in the fridge for up to 5 days. For longer storage, freeze wrapped slices for up to 2 months.
