Ingredients
- Strong brewed coffee or espresso: It is the foundation for flavor so choose a good quality bold roast
- Granulated sugar: For sweetness and to balance the coffee go for fine granulated for easy dissolving
- Brown sugar: Adds deeper caramel notes and a hint of molasses plus keeps the sauce glossy
- Unsalted butter: Provides richness and smooth texture European style butter tastes extra creamy
- Cornstarch: Thickens the sauce to a perfect pourable texture Make sure it is clump free for the best result
- Cold water: Used to dissolve the cornstarch for lump free mixing use cold not warm
- Vanilla extract: Rounds out bitter notes and adds warmth real vanilla extract gives the best fragrance
- Pinch of salt: Brightens all the flavors a flaky salt or fine sea salt works nicely

- Finish With Butter and Vanilla:
- Take the saucepan off the heat Immediately add the butter vanilla and a pinch of salt Stir gently until the butter melts is fully mixed in and the sauce looks perfectly smooth and shiny
