Brew the coffee: Start by brewing a strong cup of your favorite coffee.
Mix the cream: In a small saucepan, warm the heavy cream over low heat. Stir in the sugar-free vanilla syrup and cocoa powder until fully combined.
Combine with coffee: Pour the warmed cream mixture into your brewed coffee.
Add whiskey (optional): For a true Irish cream taste, stir in 1 tablespoon of whiskey. This step is optional but gives an authentic Irish cream flavor.
Serve: Stir well and enjoy your delicious keto Irish cream coffee, either hot or iced.
