Stir in 3 tablespoons of Greek yogurt and 1 tablespoon of water until well combined.
Step 4: Sweeten Things Up
Add 3 tablespoons of granulated sugar, 2 tablespoons of cocoa powder, 1 tablespoon of light brown sugar, and ½ teaspoon of vanilla extract. If you’re using instant espresso granules, add them here too. Mix until all the ingredients are well blended.
