Step 1

Add the large ice cube to a stemmed, wide-mouthed cocktail glass. Using the back of a large spoon, carefully pour the stout into the glass over the ice cube. Carefully layer the espresso liqueur, using the back of the spoon again, over the ice cube.

Step 2

In a shaker, add some ice, the heavy cream and curacao and whip-shake until combined. Float the cream on top of the coffee-infused stout, layering again with the back of a large spoon. Garnish with a couple coffee beans and serve immediately.
